This document defines a specific set of tests that vendors can use to measure and report the performance characteristics of ATM network devices. The results of these tests will provide the user comparable data from different vendors with which to evaluate these devices. The methods defined in this memo are based on RFC 2544 "Benchmarking Methodology for Network Interconnect Devices".
本文档定义了一组特定的测试，供应商可以使用这些测试来测量和报告ATM网络设备的性能特征。这些测试的结果将为用户提供来自不同供应商的可比数据，用于评估这些设备。本备忘录中定义的方法基于RFC 2544“网络互连设备基准测试方法”。
The document "Terminology for ATM Benchmarking" (RFC 2761), defines many of the terms that are used in this document. The terminology document should be consulted before attempting to make use of this document.
文件“ATM基准术语”（RFC 2761）定义了本文件中使用的许多术语。在尝试使用本文件之前，应查阅术语文件。
The BMWG produces two major classes of documents: Benchmarking Terminology documents and Benchmarking Methodology documents. The Terminology documents present the benchmarks and other related terms. The Methodology documents define the procedures required to collect the benchmarks cited in the corresponding Terminology documents.
BMWG产生两大类文件：基准术语文件和基准方法文件。术语文件介绍了基准和其他相关术语。方法文件规定了收集相应术语文件中引用的基准所需的程序。
This document is based on the requirement that a test device is available. The test device can either be off the shelf or can be easily built with current technologies. The test device must have a transmitting and receiving port for the interface type under test. The test device must be configured to transmit test PDUs and to analyze received PDUs. The test device should be able to transmit and analyze received data at the same time.
本文件基于测试设备可用的要求。测试设备可以是现成的，也可以使用当前技术轻松构建。测试设备必须具有用于被测接口类型的发送和接收端口。测试设备必须配置为传输测试PDU和分析接收到的PDU。测试设备应能够同时传输和分析接收到的数据。
There are a number of tests described in this document that do not apply to each SUT. Vendors should perform all of the tests that can be supported by a specific product type. It will take some time to perform all of the recommended tests under all of the recommended conditions.
本文件中描述的许多测试不适用于每个SUT。供应商应执行特定产品类型支持的所有测试。在所有推荐条件下执行所有推荐测试需要一些时间。
Performing all of the tests in this document will result in a great deal of data. The applicability of this data to the evaluation of a particular SUT will depend on its expected use and the configuration of the network in which it will be used. For example, the time required by a switch to provide ILMI services will not be a pertinent measurement in a network that does not use the ILMI protocol, such as an ATM WAN. Evaluating data relevant to a particular network installation may require considerable experience, which may not be readily available. Finally, test selection and evaluation of test results must be done with an understanding of generally accepted testing practices regarding repeatability, variance and the statistical significance of a small numbers of trials.
执行本文档中的所有测试将产生大量数据。该数据对特定SUT评估的适用性将取决于其预期用途和使用网络的配置。例如，在不使用ILMI协议的网络（如ATM WAN）中，交换机提供ILMI服务所需的时间将不是相关的度量。评估与特定网络安装相关的数据可能需要相当多的经验，而这些经验可能并不容易获得。最后，测试选择和测试结果的评估必须在了解关于重复性、方差和少量试验统计显著性的公认测试实践的情况下进行。
In this document, the words that are used to define the significance of each particular requirement are capitalized. These words are:
在本文件中，用于定义每个特定要求重要性的词语大写。这些词是：
* "MUST" This word, or the words "REQUIRED" and "SHALL" mean that the item is an absolute requirement of the specification.
* “必须”一词，或“要求”和“应”一词表示该项目是本规范的绝对要求。
* "SHOULD" This word or the adjective "RECOMMENDED" means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications should be understood and the case carefully weighed before choosing a different course.
* “应该”这个词或形容词“建议”意味着在特定情况下可能存在忽略该项目的正当理由，但在选择不同的课程之前，应理解其全部含义并仔细权衡情况。
* "MAY" This word or the adjective "OPTIONAL" means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item.
* “MAY”这个词或形容词“OPTIONAL”表示这个项目确实是可选的。一个供应商可能会选择包括该项目，因为特定的市场需要它，或者因为它增强了产品，例如；另一个供应商可以省略相同的项目。
An implementation is not compliant if it fails to satisfy one or more of the MUST requirements for the protocols it implements. An implementation that satisfies all the MUST and all the SHOULD requirements for its protocols is said to be "unconditionally compliant"; one that satisfies all the MUST requirements but not all the SHOULD requirements for its protocols is said to be "conditionally compliant".
如果一个实现未能满足其实现的协议的一个或多个必需要求，则该实现是不兼容的。满足其协议所有必须和应该要求的实现称为“无条件兼容”；满足其协议的所有必须要求但并非所有应该要求的协议称为“有条件地符合”。
The test device can be connected to the SUT in a variety of configurations depending on the test point. The following configurations will be used for the tests described in this document.
根据测试点的不同，测试设备可以多种配置连接到SUT。以下配置将用于本文档中描述的测试。
1) Uni-directional connection: The test devices transmit port (labeled Tx) is connected to the SUT receive port (labeled Rx). The SUTs transmit port is connected to the test device receive port (see Figure 1). In this configuration, the test device can verify that all transmitted packets are acknowledged correctly. Note that this configuration does not verify internal system functions, but verifies one port on the SUT.
1) 单向连接：测试设备传输端口（标记为Tx）连接至SUT接收端口（标记为Rx）。SUTs传输端口连接到测试设备接收端口（见图1）。在该配置中，测试设备可以验证所有发送的分组是否被正确确认。请注意，此配置不验证内部系统功能，但验证SUT上的一个端口。

2) Bi-directional connection: The test devices first transmit port is connected to the SUTs first receive port. The SUTs first transmit port is connected to the test devices first receive port. The test devices second transmit port is connected to the SUTs second receive port. The SUTs second transmit port is connected to the test devices second receive port (see Figure 2). In this configuration, the test device can determine if all of the transmitted packets were received and forwarded correctly. Note that this configuration does verify internal system functions, since it verifies two ports on the SUT.
2) 双向连接：测试设备的第一个发送端口连接到SUTs的第一个接收端口。SUTs第一个发送端口连接到测试设备的第一个接收端口。测试设备的第二个发送端口连接到SUTs的第二个接收端口。SUTs第二个发送端口连接到测试设备第二个接收端口（见图2）。在该配置中，测试设备可以确定是否所有发送的分组都被正确接收和转发。请注意，此配置确实验证内部系统功能，因为它验证SUT上的两个端口。

The test devices second transmit port is connected to the SUT2 receive port. The SUT2 transmit port is connected to the test devices second receive port (see Figure 3). In this configuration, the test device can determine if all of the packets transmitted by SUT1 were correctly acknowledged by SUT2. Note that this configuration does not verify internal system functions, but verifies one port on each SUT.
3) 单向直通连接：测试设备的第一个发送端口连接到SUT1接收端口。SUT1传输端口连接到测试设备的第一个接收端口。测试设备的第二个发送端口连接到SUT2接收端口。SUT2传输端口连接到测试设备的第二个接收端口（见图3）。在该配置中，测试设备可以确定SUT1发送的所有分组是否被SUT2正确确认。请注意，此配置不验证内部系统功能，但验证每个SUT上的一个端口。

The SUT MUST be configured as described in the SUT users guide. Specifically, it is expected that all of the supported protocols will be configured and enabled. It is expected that all of the tests will be run without changing the configuration or setup of the SUT in any way other than that required to do the specific test. For example, it is not acceptable to disable all but one transport protocol when testing the throughput of that protocol. If PNNI or BISUP is used to initiate switched virtual connections (SVCs), the SUT configuration SHOULD include the normally recommended routing update intervals and keep alive frequency. The specific version of the software and the exact SUT configuration, including what functions are disabled and used during the tests MUST be included as part of the report of the results.
必须按照SUT用户指南中的说明配置SUT。具体而言，预计将配置并启用所有受支持的协议。预计所有测试都将在不改变SUT配置或设置的情况下运行，而不是以执行特定测试所需的任何方式。例如，在测试一个传输协议的吞吐量时，禁用该协议之外的所有传输协议是不可接受的。如果使用PNNI或BISUP启动交换虚拟连接（SVC），SUT配置应包括通常建议的路由更新间隔和保持活动频率。软件的特定版本和确切SUT配置，包括测试期间禁用和使用的功能，必须作为结果报告的一部分。
The formats of the test IP PDUs to use for TCP/IP and UPC/IP over ATM are shown in Appendix C: Test Frame Formats. Note that these IP PDUs are in accordance with RFC 2225. These exact IP PDU formats SHOULD be used in the tests described in this document for this protocol/media combination. These IP PDUs will be used as a template for testing other protocol/media combinations. The specific formats that are used to define the test IP PDUs for a particular test series MUST be included in the report of the results.
用于TCP/IP和UPC/IP over ATM的测试IP PDU的格式如附录C：测试帧格式所示。请注意，这些IP PDU符合RFC 2225。这些精确的IP PDU格式应用于本文件中描述的该协议/媒体组合的测试中。这些IP PDU将用作测试其他协议/媒体组合的模板。用于定义特定测试系列的测试IP PDU的特定格式必须包含在结果报告中。
All of the described tests SHOULD be performed using a number of IP PDU sizes. Specifically, the sizes SHOULD include the maximum and minimum legitimate sizes for the protocol under test on the media under test and enough sizes in between to be able to get a full characterization of the SUT performance. Except where noted, at least five IP PDU sizes SHOULD be tested for each test condition.
应使用多种IP PDU尺寸执行所有描述的测试。具体而言，大小应包括在被测介质上被测协议的最大和最小合法大小，以及能够获得SUT性能完整特征的足够大小。除非另有说明，否则应针对每个测试条件测试至少五个IP PDU尺寸。
Theoretically the minimum size UDP Echo request IP PDU would consist of an IP header (minimum length 20 octets), a UDP header (8 octets), AAL5 trailer (8 octets) and an LLC/SNAP code point header (8 octets); therefore, the minimum size PDU will fit into one ATM cell. The theoretical maximum IP PDU size is determined by the size of the length field in the IP header. In almost all cases the actual maximum and minimum sizes are determined by the limitations of the media. In the case of ATM, the maximum IP PDU size SHOULD be the ATM MTU size, which is 9180 octets.
理论上，最小大小的UDP回显请求IP PDU将包括一个IP报头（最小长度20个八位字节）、一个UDP报头（8个八位字节）、一个AAL5拖车（8个八位字节）和一个LLC/SNAP码点报头（8个八位字节）；因此，最小尺寸的PDU将适合一个ATM信元。理论最大IP PDU大小由IP报头中长度字段的大小决定。在几乎所有情况下，实际的最大和最小尺寸都是由介质的限制决定的。对于ATM，最大IP PDU大小应为ATM MTU大小，即9180个八位字节。
In theory it would be ideal to distribute the IP PDU sizes in a way that would evenly distribute the theoretical IP PDU rates. These recommendations incorporate this theory but specify IP PDU sizes, which are easy to understand and remember. In addition, many of the same IP PDU sizes are specified on each of the media types to allow for easy performance comparisons.
理论上，以一种能够均匀分布理论IP PDU速率的方式分布IP PDU大小是理想的。这些建议结合了这一理论，但指定了易于理解和记忆的IP PDU大小。此外，在每种介质类型上都指定了许多相同的IP PDU大小，以便进行性能比较。
Note: The inclusion of an unrealistically small IP PDU size on some of the media types (i.e., with little or no space for data) is to help characterize the per-IP PDU processing overhead of the SUT.
Note: The inclusion of an unrealistically small IP PDU size on some of the media types (i.e., with little or no space for data) is to help characterize the per-IP PDU processing overhead of the SUT.translate error, please retry
The IP PDU sizes that will be used are:
将使用的IP PDU大小为：
44, 64, 128, 256, 1024, 1518, 2048, 4472, 9180
44, 64, 128, 256, 1024, 1518, 2048, 4472, 9180
The minimum size IP PDU for UDP on ATM is 44 octets, the minimum size of 44 is recommended to allow direct comparison to token ring performance. The IP PDU size of 4472 is recommended instead of the
ATM上UDP的最小IP PDU大小为44个八位字节，建议最小大小为44，以便与令牌环性能进行直接比较。建议IP PDU的大小为4472，而不是
theoretical FDDI maximum size of 4500 octets in order to permit the same type of comparison. An IP (i.e., not UDP) IP PDU may be used in addition if a higher data rate is desired, in which case the minimum IP PDU size is 28 octets.
理论上FDDI的最大大小为4500个八位字节，以便进行相同类型的比较。如果需要更高的数据速率，则还可以使用IP（即，非UDP）IP PDU，在这种情况下，最小IP PDU大小为28个八位字节。
The test equipment SHOULD discard any IP PDUs received during a test run that are not actual forwarded test IP PDUs. For example, keep-alive and routing update IP PDUs SHOULD NOT be included in the count of received IP PDUs. In any case, the test equipment SHOULD verify the length of the received IP PDUs and check that they match the expected length.
测试设备应丢弃在测试运行期间接收到的不是实际转发的测试IP PDU的任何IP PDU。例如，“保持活动”和“路由更新”IP PDU不应包含在接收的IP PDU计数中。在任何情况下，测试设备都应验证接收到的IP PDU的长度，并检查它们是否与预期长度匹配。
Preferably, the test equipment SHOULD include sequence numbers in the transmitted IP PDUs and check for these numbers on the received IP PDUs. If this is done, the reported results SHOULD include, in addition to the number of IP PDUs dropped, the number of IP PDUs that were received out of order, the number of duplicate IP PDUs received and the number of gaps in the received IP PDU numbering sequence. This functionality is required for some of the described tests.
优选地，测试设备应包括发送的IP pdu中的序列号，并在接收的IP pdu上检查这些序列号。如果这样做，报告的结果除应包括丢弃的IP PDU数量外，还应包括无序接收的IP PDU数量、接收到的重复IP PDU数量以及接收到的IP PDU编号序列中的间隙数量。某些所述测试需要此功能。
It is useful to characterize the SUTs performance under a number of conditions. Some of these conditions are noted below. The reported results SHOULD include as many of these conditions as the test equipment is able to generate. The suite of tests SHOULD be run first without any modifying conditions, then repeated under each of the modifying conditions separately. To preserve the ability to compare the results of these tests, any IP PDUs that are required to generate the modifying conditions (excluding management queries) will be included in the same data stream as that of the normal test IP PDUs and in place of one of the test IP PDUs. They MUST not be supplied to the SUT on a separate network port.
在多种条件下表征SUTs的性能非常有用。其中一些情况如下所述。报告的结果应包括测试设备能够产生的所有这些条件。测试套件应首先在没有任何修改条件的情况下运行，然后在每个修改条件下分别重复。为了保持比较这些测试结果的能力，生成修改条件（不包括管理查询）所需的任何IP PDU都将包含在与正常测试IP PDU相同的数据流中，并取代其中一个测试IP PDU。它们不得通过单独的网络端口提供给SUT。
Most ATM data networks now make use of ILMI, signaling and OAM. In many environments, there can be a number of management stations sending queries to the same SUT at the same time.
大多数ATM数据网络现在使用ILMI、信令和OAM。在许多环境中，可能有多个管理站同时向同一SUT发送查询。
Management queries MUST be made in accordance with the applicable specification, e.g., ILMI sysUpTime getNext requests will be made in accordance with ILMI 4.0. The response to the query MUST be verified by the test equipment. Note that, for each management protocol in
管理查询必须根据适用规范进行，例如，ILMI sysUpTime getNext请求将根据ILMI 4.0进行。对查询的响应必须由测试设备进行验证。请注意，对于中的每个管理协议
use, this requires that the test equipment implement the associated protocol state machine. One example of the specific query IP PDU (ICMP) that should be used is shown in Appendix C.
使用时，这要求测试设备实现相关的协议状态机。附录C中显示了应使用的特定查询IP PDU（ICMP）的一个示例。
The processing of PNNI updates could have a significant impact on the ability of a switch to forward cells and complete calls. If PNNI is configured on the SUT, one routing update MUST be transmitted before the first test IP PDU is transmitted during the trial. The test SHOULD verify that the SUT has properly processed the routing update.
处理PNNI更新可能对交换机转发小区和完成呼叫的能力产生重大影响。如果在SUT上配置了PNNI，则在试验期间传输第一个测试IP PDU之前，必须传输一个路由更新。测试应验证SUT是否正确处理了路由更新。
PNNI routing update IP PDUs SHOULD be sent at the rate specified in Appendix B. Appendix C defines one routing update PDU for the TCP/IP over ATM example. The routing updates are designed to change the routing on a number of networks that are not involved in the forwarding of the test data. The first IP PDU sets the routing table state to "A", the second one changes the state to "B". The IP PDUs MUST be alternated during the trial. The test SHOULD verify that the SUT has properly processed the routing update.
PNNI路由更新IP PDU应按照附录B中规定的速率发送。附录C为TCP/IP over ATM示例定义了一个路由更新PDU。路由更新旨在更改多个不涉及测试数据转发的网络上的路由。第一个IP PDU将路由表状态设置为“A”，第二个IP PDU将状态更改为“B”。IP PDU必须在试验期间交替使用。测试应验证SUT是否正确处理了路由更新。
Filters are added to switches to selectively inhibit the forwarding of cells that would normally be forwarded. This is usually done to implement security controls on the data that is accepted between one area and another. Different products have different capabilities to implement filters. Filters are applicable only if the SUT supports the filtering feature.
将过滤器添加到交换机，以选择性地抑制通常会转发的小区的转发。这样做通常是为了对一个区域和另一个区域之间接受的数据实施安全控制。不同的产品具有不同的功能来实现过滤器。仅当SUT支持过滤功能时，过滤器才适用。
The SUT SHOULD be first configured to add one filter condition and the tests performed. This filter SHOULD permit the forwarding of the test data stream. This filter SHOULD be of the form as described in the SUT Users Guide.
应首先将SUT配置为添加一个过滤器条件和执行的测试。该过滤器应允许转发测试数据流。此过滤器应采用SUT用户指南中所述的形式。
The SUT SHOULD be then reconfigured to implement a total of 25 filters. The first 24 of these filters SHOULD be based on 24 separate ATM NSAP Network Prefix addresses.
然后应重新配置SUT，以实现总共25个过滤器。前24个过滤器应基于24个单独的ATM NSAP网络前缀地址。
The 24 ATM NSAP Network Prefix addresses SHOULD not be any that are represented in the test data stream. The last filter SHOULD permit the forwarding of the test data stream. By "first" and "last" we mean to ensure that in the second case, 25 conditions must be checked before the data IP over ATM PDUs will match the conditions that permit the forwarding of the IP PDU. Of course, if the SUT reorders the filters or does not use a linear scan of the filter rules the effect of the sequence in which the filters are input is properly lost.
24个ATM NSAP网络前缀地址不应是测试数据流中表示的任何地址。最后一个过滤器应允许转发测试数据流。通过“第一个”和“最后一个”，我们的意思是确保在第二种情况下，在ATM PDU上的IP数据与允许IP PDU转发的条件匹配之前，必须检查25个条件。当然，如果SUT对过滤器重新排序，或者不使用过滤器规则的线性扫描，则过滤器输入顺序的效果将正确丢失。
The exact filters configuration command lines used SHOULD be included with the report of the results.
结果报告中应包括使用的确切过滤器配置命令行。
Two sets of filter addresses are required, one for the single filter case and one for the 25 filter case.
需要两组筛选器地址，一组用于单个筛选器，另一组用于25个筛选器。
The single filter case should permit traffic from ATM address [Switch Network Prefix] 00 00 00 00 00 01 00 to ATM address [Switch Network Prefix] 00 00 00 00 00 02 00 and deny all other traffic. Note that the 13 octet Switch Network Prefix MUST be configured before this test can be run.
单个筛选器案例应允许从ATM地址[交换机网络前缀]00 00 01 00到ATM地址[交换机网络前缀]00 00 00 02 00的流量，并拒绝所有其他流量。请注意，在运行此测试之前，必须配置13个八位组交换机网络前缀。
The 25 filter case should follow the following sequence.
25滤清器壳体应遵循以下顺序。

All previous filter conditions should be cleared from the switch before this sequence is entered. The sequence is selected to test to see if the switch sorts the filter conditions or accepts them in the order that they were entered. Both of these procedures will result in a greater impact on performance than will some form of hash coding.
在进入该序列之前，应清除开关上所有先前的过滤条件。选择该序列进行测试，以查看开关是否对筛选条件进行排序，或是否按照输入顺序接受筛选条件。这两个过程对性能的影响都比某种形式的散列编码更大。
It is easier to implement these tests using a single logical stream of data, with one source ATM address and one destination ATM address, and for some conditions like the filters described above, a practical requirement. Networks in the real world are not limited to single streams of data. The test suite SHOULD be first run with a single ATM source and destination address pair. The tests SHOULD then be repeated with using a random destination address. In the case of testing single switches, the addresses SHOULD be random and uniformly distributed over a range of 256 seven octet user parts. In the case of testing multiple interconnected switches, the addresses SHOULD be random and uniformly distributed over the 256 network prefixes, each of which should support 256 seven octet user parts. The specific address ranges to use for ATM are shown in Appendix A. IP to ATM address mapping MUST be accomplished as described in RFC 2225.
使用单个逻辑数据流、一个源ATM地址和一个目标ATM地址来实现这些测试更容易，对于某些情况，如上述过滤器，这是一个实际要求。现实世界中的网络并不局限于单个数据流。测试套件应首先使用单个ATM源和目标地址对运行。然后应使用随机目标地址重复测试。在测试单个交换机的情况下，地址应该是随机的，并且均匀分布在256个七个八位字节的用户部分上。在测试多个互连交换机的情况下，地址应随机均匀分布在256个网络前缀上，每个网络前缀应支持256个七个八位字节的用户部分。ATM使用的具体地址范围如附录A所示。IP到ATM地址映射必须按照RFC 2225中的描述完成。
It is not reasonable that all of the routing information necessary to forward the test stream, especially in the multiple address case, will be manually set up. If PNNI and/or ILMI are running, at the start of each trial a routing update MUST be sent to the SUT. This routing update MUST include all of the ATM addresses that will be required for the trial. This routing update will have to be repeated at the interval required by PNNI or ILMI. An example of the format and repetition interval of the update IP PDUs is given in Appendix B (interval and size) and Appendix C (format).
将手动设置转发测试流所需的所有路由信息（尤其是在多地址情况下）是不合理的。如果PNNI和/或ILMI正在运行，则在每次试验开始时，必须向SUT发送路由更新。此路由更新必须包括试用所需的所有ATM地址。必须按照PNNI或ILMI要求的时间间隔重复此路由更新。附录B（间隔和大小）和附录C（格式）给出了更新IP PDU的格式和重复间隔示例。
Bidirectional performance tests SHOULD be run with the same data rate being offered from each direction. The sum of the data rates should not exceed the theoretical limit for the media.
双向性能测试应以每个方向提供的相同数据速率运行。数据速率之和不应超过介质的理论极限。
The full suite of tests SHOULD be run with the appropriate modifiers for a single receive and transmit port on the SUT. If the internal design of the SUT has multiple distinct pathways, for example, multiple interface cards each with multiple network ports, then all possible permutations of pathways SHOULD be tested separately. If multiple interconnected switches are tested, the test MUST specify routes, which allow only one path between source and destination ATM addresses.
对于SUT上的单个接收和传输端口，应使用适当的修饰符运行全套测试。如果SUT的内部设计有多个不同的路径，例如，多个接口卡，每个接口卡具有多个网络端口，则应单独测试所有可能的路径排列。如果测试多个互连交换机，则测试必须指定路由，在源和目标ATM地址之间只允许一条路径。
Many switch products provide several network ports on the same interface module. Each port on an interface module SHOULD be stimulated in an identical manner. Specifically, half of the ports on each module SHOULD be receive ports and half SHOULD be transmit ports. For example if a SUT has two interface module each of which has four ports, two ports on each interface module be receive ports and two will be transmit ports. Each receive port MUST be offered the same data rate. The addresses in the input data streams SHOULD be set so that an IP PDU will be directed to each of the transmit ports in sequence. That is, all transmit ports will receive an identical distribution of IP PDUs from a particular receive port.
许多交换机产品在同一接口模块上提供多个网络端口。接口模块上的每个端口应以相同的方式进行模拟。具体来说，每个模块上的一半端口应为接收端口，一半端口应为传输端口。例如，如果SUT有两个接口模块，每个模块有四个端口，则每个接口模块上的两个端口为接收端口，两个端口为传输端口。每个接收端口必须提供相同的数据速率。应设置输入数据流中的地址，以便将IP PDU按顺序定向到每个传输端口。也就是说，所有发送端口将从特定接收端口接收相同的IP PDU分发。
Consider the following 6 port SUT:
考虑以下6个端口SUT：
--------------
---------| Rx A Tx X|--------
---------| Rx B Tx Y|--------
---------| Rx C Tx Z|--------
--------------
--------------
---------| Rx A Tx X|--------
---------| Rx B Tx Y|--------
---------| Rx C Tx Z|--------
--------------
The addressing of the data streams for each of the inputs SHOULD be:
每个输入的数据流寻址应为：
stream sent to Rx A: IP PDU to Tx X, IP PDU to Tx Y, IP PDU to Tx Z stream sent to Rx B: IP PDU to Tx X, IP PDU to Tx Y, IP PDU to Tx Z stream sent to Rx C IP PDU to Tx X, IP PDU to Tx Y, IP PDU to Tx Z
发送到Rx的流A:IP PDU到Tx X、IP PDU到Tx Y、IP PDU到Tx Z发送到Rx B:IP PDU到Tx X、IP PDU到Tx Y、IP PDU到Tx Z发送到Rx C IP PDU到Tx X、IP PDU到Tx Y、IP PDU到Tx Z
Note: Each stream contains the same sequence of IP destination addresses; therefore, each transmit port will receive 3 IP PDUs simultaneously. This procedure ensures that the SUT will have to process multiple IP PDUs addressed to the same transmit port simultaneously.
注意：每个流包含相同的IP目标地址序列；因此，每个发送端口将同时接收3个IP PDU。此过程确保SUT必须同时处理寻址到同一传输端口的多个IP PDU。
The same configuration MAY be used to perform a bi-directional multi-stream test. In this case all of the ports are considered both receive and transmit ports. Each data stream MUST consist of IP PDUs whose addresses correspond to the ATM addresses all of the other ports.
相同的配置可用于执行双向多流测试。在这种情况下，所有端口都被视为接收端口和发送端口。每个数据流必须由IP PDU组成，其地址对应于所有其他端口的ATM地址。
This document does not address the issue of testing the effects of a mixed protocol environment other than to suggest that if such tests are wanted then PDUs SHOULD be distributed between all of the test protocols. The distribution MAY approximate the conditions on the network in which the SUT would be used.
本文件不涉及测试混合协议环境影响的问题，只是建议如果需要此类测试，则应在所有测试协议之间分配PDU。分布可能近似于使用SUT的网络上的条件。
This document does not address the issue of testing the effects of a mixed IP PDU size environment other than to suggest that, if such tests are required, then IP PDU size SHOULD be evenly distributed among all of the PDU sizes listed in this document. The distribution MAY approximate the conditions on the network in which the SUT would be used.
本文件不涉及测试混合IP PDU大小环境的影响问题，只是建议如果需要此类测试，则IP PDU大小应均匀分布在本文件中列出的所有PDU大小中。分布可能近似于使用SUT的网络上的条件。
In the performance testing of a single SUT, the paradigm can be described as applying some input to a SUT and monitoring the output. The results of which can be used to form a basis of characterization of that device under those test conditions.
在单个SUT的性能测试中，范例可以描述为将一些输入应用到SUT并监视输出。其结果可用于在这些试验条件下形成该装置特性的基础。
This model is useful when the test input and output are homogeneous (e.g., 64-byte IP, AAL5 PDUs into the SUT; 64 byte IP, AAL5 PDUs out).
当测试输入和输出是同质的（例如，64字节IP，AAL5 PDU进入SUT；64字节IP，AAL5 PDU输出）时，此模型非常有用。
By extending the single SUT test model, reasonable benchmarks regarding multiple SUTs or heterogeneous environments may be collected. In this extension, the single SUT is replaced by a system of interconnected network SUTs. This test methodology would support the benchmarking of a variety of device/media/service/protocol combinations. For example, a configuration for a LAN-to-WAN-to-LAN test might be:
通过扩展单个SUT测试模型，可以收集关于多个SUT或异构环境的合理基准。在此扩展中，单个SUT被互连网络SUT系统所取代。该测试方法将支持各种设备/媒体/服务/协议组合的基准测试。例如，LAN到WAN到LAN测试的配置可能是：
(1) ATM UNI -> SUT 1 -> BISUP -> SUT 2 -> ATM UNI
(1) ATM UNI -> SUT 1 -> BISUP -> SUT 2 -> ATM UNI
Or an extended LAN configuration might be:
或者，扩展LAN配置可能是：
(2) ATM UNI -> SUT 1 -> PNNI Network -> SUT 2 -> ATM UNI
(2) ATM UNI -> SUT 1 -> PNNI Network -> SUT 2 -> ATM UNI
In both examples 1 and 2, end-to-end benchmarks of each system could be empirically ascertained. Other behavior may be characterized through the use of intermediate devices. In example 2, the configuration may be used to give an indication of the effect of PNNI routing on IP throughput.
在示例1和2中，可以根据经验确定每个系统的端到端基准。其他行为可通过使用中间装置来表征。在示例2中，该配置可用于指示PNNI路由对IP吞吐量的影响。
Because multiple SUTs are treated as a single system, there are limitations to this methodology. For instance, this methodology may yield an aggregate benchmark for a tested system. That benchmark alone, however, may not necessarily reflect asymmetries in behavior between the SUTs, latencies introduced by other apparatus (e.g., CSUs/DSUs, switches), etc.
由于多个SUT被视为单个系统，因此该方法存在局限性。例如，此方法可能会为测试系统生成一个聚合基准。然而，该基准本身可能不一定反映SUT之间行为的不对称性、由其他设备（例如，CSU/DSU、交换机）引入的延迟等。
Further, care must be used when comparing benchmarks of different systems by ensuring that the SUTs' features and configuration of the tested systems have the appropriate common denominators to allow comparison.
此外，在比较不同系统的基准时必须小心，确保测试系统的SUT特性和配置具有适当的公分母，以便进行比较。
The maximum IP PDU rates that should be used when testing LAN connections SHOULD be the listed theoretical maximum rate for the IP PDU size on the media.
测试LAN连接时应使用的最大IP PDU速率应为介质上IP PDU大小的理论最大速率。
The maximum IP PDU rate that should be used when testing WAN connections SHOULD be greater than the listed theoretical maximum rate for the IP PDU size on that speed connection. The higher rate for WAN tests is to compensate for the fact that some vendors employ various forms of header compression.
测试WAN连接时应使用的最大IP PDU速率应大于该速度连接上列出的IP PDU大小的理论最大速率。广域网测试的较高速率是为了补偿一些供应商采用各种形式的报头压缩的事实。
A list of maximum IP PDU rates for LAN connections is included in Appendix B.
LAN连接的最大IP PDU速率列表包含在附录B中。
It is convenient to measure the SUT performance under steady state load; however, this is an unrealistic way to gauge the functioning of a SUT. Actual network traffic normally consists of bursts of IP PDUs.
可以方便地测量稳态负载下的SUT性能；然而，这是衡量SUT功能的不切实际的方法。实际网络流量通常由IP PDU突发组成。
Some of the tests described below SHOULD be performed with both constant bit rate, bursty Unspecified Bit Rate (UBR) Best Effort [AF-TM4.1] and Variable Bit Rate Non-real Time (VBR-nrt) Best Effort [AF-TM4.1]. The IP PDUs within a burst are transmitted with the minimum legitimate inter-IP PDU gap.
应使用恒定比特率、突发未指定比特率（UBR）最大努力[AF-TM4.1]和可变比特率非实时（VBR nrt）最大努力[AF-TM4.1]执行以下描述的一些测试。突发中的IP PDU以最小的合法IP PDU间隙传输。
The objective of the test is to determine the minimum interval between bursts that the SUT can process with no IP PDU loss. Tests SHOULD be run with burst sizes of 10% of Maximum Burst Size (MBS), 20% of MBS, 50% of MBS and 100% MBS. Note that the number of IP PDUs in each burst will depend on the PDU size. For UBR, the MBS refers to the associated VBR traffic parameters.
测试的目的是确定SUT在不丢失IP PDU的情况下可以处理的最小脉冲间隔。测试应在最大突发大小（MBS）的10%、MBS的20%、MBS的50%和MBS的100%的突发大小下运行。请注意，每个突发中的IP PDU数量将取决于PDU大小。对于UBR，MBS指的是相关的VBR流量参数。
A particular test consists of multiple trials. Each trial returns one piece of information, for example the loss rate at a particular input IP PDU rate. Each trial consists of five of phases:
一个特定的测试由多个试验组成。每次试验返回一条信息，例如特定输入IP PDU速率下的丢失率。每个试验包括五个阶段：
a) If the SUT is a switch supporting PNNI, send the routing update to the SUT receive port and wait two seconds to be sure that the routing has settled.
a) 如果SUT是支持PNNI的交换机，请将路由更新发送到SUT接收端口，并等待两秒钟以确保路由已解决。
b) Send an ATM ARP PDU to determine the ATM address corresponding to the destination IP address. The formats of the ATM ARP PDU that should be used are shown in the Test Frame Formats document and MUST be in accordance with RFC 2225.
b) 发送ATM ARP PDU以确定与目标IP地址对应的ATM地址。应使用的ATM ARP PDU格式如测试帧格式文件所示，且必须符合RFC 2225。
c) Stimulate SUT with traffic load.
c) 用流量负载刺激SUT。
d) Wait for two seconds for any residual IP PDUs to be received.
d) 等待两秒钟，以便接收任何剩余的IP PDU。
e) Wait for at least five seconds for the SUT to restabilize.
e) 至少等待5秒钟，使SUT重新稳定。
The objective of the tests defined in this document is to accurately characterize the behavior of a particular piece of network equipment under varying traffic loads. The choice of test duration must be a compromise between this objective and keeping the duration of the benchmarking test suite within reasonable bounds. The SUT SHOULD be stimulated for at least 60 seconds. If this time period results in a high variance in the test results, the SUT SHOULD be stimulated for at least 300 seconds.
本文件中定义的测试目标是准确描述特定网络设备在不同流量负载下的行为。测试持续时间的选择必须在这一目标和将基准测试套件的持续时间保持在合理范围内之间达成妥协。应刺激SUT至少60秒。如果该时间段导致测试结果出现较大差异，则应刺激SUT至少300秒。
The SUT MUST be able to respond to address resolution requests sent by another SUT, an ATM ARP server or the test equipment in accordance with RFC 2225.
根据RFC 2225，SUT必须能够响应另一SUT、ATM ARP服务器或测试设备发送的地址解析请求。
2.25. Synchronized Payload Bit Pattern.
2.25. 同步有效负载位模式。
Some measurements assume that both the transmitter and receiver payload information is synchronized. Synchronization MUST be achieved by supplying a known bit pattern to both the transmitter and receiver. This bit pattern MUST be one of the following: PRBS-15, PRBS-23, 0xFF00, or 0xAA55.
一些测量假设发射机和接收机有效载荷信息是同步的。同步必须通过向发射机和接收机提供已知的位模式来实现。此位模式必须是以下之一：PRBS-15、PRBS-23、0xFF00或0xAA55。

The cell delay measurements assume that both the transmitter and receiver timestamp information is synchronized. Synchronization SHOULD be achieved by supplying a common clock signal (minimum of 100 Mhz or 10 ns resolution) to both the transmitter and receiver. The maximum timestamp values MUST be recorded to ensure synchronization in the case of counter rollover. The cell delay measurements SHOULD utilize the O.191 cell (ITUT-O.191) encapsulated in a valid IP packet. If the O.191 cell is not available, a test cell encapsulated in a valid IP packet MAY be used. The test cell MUST contain a transmit timestamp which can be correlated with a receive timestamp. A description of the test cell MUST be included in the test results. The description MUST include the timestamp length (in bits), counter rollover value, and the timestamp accuracy (in ns).
小区延迟测量假定发射机和接收机的时间戳信息是同步的。同步应通过向发射机和接收机提供公共时钟信号（最低100 Mhz或10 ns分辨率）来实现。必须记录最大时间戳值，以确保计数器翻转时的同步。小区延迟测量应利用封装在有效IP包中的O.191小区（ITUT-O.191）。如果O.191单元不可用，则可以使用封装在有效IP分组中的测试单元。测试单元必须包含可与接收时间戳关联的发送时间戳。测试结果中必须包含测试单元的说明。描述必须包括时间戳长度（以位为单位）、计数器翻转值和时间戳精度（以ns为单位）。

Procedure:
程序：
1) Set up the SUT and test device using the bi-directional configuration.
1) 使用双向配置设置SUT和测试设备。
2) Configure the SUT and test device with the maximum number of VCCs supported on the SUT. For example, if the maximum number of VCCs supported on the SUT is 1024, define 256 VPIs with 4 VCIs per VPI. The VCC's MUST be configured as either a CBR, VBR, or UBR connection. The VPI/VCIs MUST not be one of the reserved ATM signaling channels (e.g., [0,5], [0,16]).

3) Send a specific number of IP packets containing timestamps at a specific constant rate through the SUT via the defined test VCCs. All of the VPI/VCI pairs will generate traffic at the same traffic rate. Since this test is not a throughput test, the rate should not be greater than 90% of line rate. The IP PDUs MUST be encapsulated in AAL5.
3) 通过定义的测试VCC，通过SUT以特定的恒定速率发送包含时间戳的特定数量的IP数据包。所有VPI/VCI对将以相同的流量率生成流量。由于该测试不是吞吐量测试，因此速率不应大于线路速率的90%。IP PDU必须封装在AAL5中。
4) Count the IP packets that are transmitted by the SUT on all VCCs to verify connectivity and load. If the count on the test device is the same on the SUT, continue the test; else lower the test device traffic rate until the counts are the same.
4) 统计SUT在所有VCC上传输的IP数据包，以验证连接和负载。如果测试设备上的计数与SUT上的计数相同，则继续测试；否则，降低测试设备通信速率，直到计数相同。
5) Record the packets timestamps at the transmitter and receiver ends of the test device for all VCCs.
5) 在所有VCC的测试设备的发射器和接收器端记录数据包时间戳。

目的：根据RFC 2761“ATM基准术语”中定义的SUT支持的最大VCC数，确定信元传输延迟中的SUT变化。
Procedure:
程序：
1) Set up the SUT and test device using the bi-directional configuration.
1) 使用双向配置设置SUT和测试设备。
2) Configure the SUT and test device with maximum number of VCCs supported on the SUT. For example, if the maximum number of VCCs supported on the SUT is 1024, define 256 VPIs with 4 VCIs per VPI. Each VCC MUST be defined as one of the Bearer classes for a total of (max VCC/3) CBR, (max VCC/3) UBR and (max VCC/3) VBR VCC's. If the maximum number of VCC's is not divisible by 3, the total for each bearer class MUST be within 3 VCC's of each other. The VPI/VCI MUST not be one of the reserved ATM signaling channels (e.g., [0,5], [0,16]).
2) Configure the SUT and test device with maximum number of VCCs supported on the SUT. For example, if the maximum number of VCCs supported on the SUT is 1024, define 256 VPIs with 4 VCIs per VPI.

The VPI/VCI MUST not be one of the reserved ATM signaling channels (e.g., [0,5], [0,16]).translate error, please retry
3) Send a specific number of IP packets containing timestamps through the SUT via the defined test VCCs. Each generated VCC stream MUST match the corresponding VCC Bearer class. All of the VPI/VCI pairs will generate traffic at the same traffic rate. Since this test is not a throughput test, the rate should not be greater than 90% of line rate. The IP PDUs MUST be encapsulated in AAL5.
3) 通过定义的测试VCC通过SUT发送特定数量的包含时间戳的IP数据包。每个生成的VCC流必须与相应的VCC承载类匹配。所有VPI/VCI对将以相同的流量率生成流量。由于该测试不是吞吐量测试，因此速率不应大于线路速率的90%。IP PDU必须封装在AAL5中。
4) Count the IP packets that are transmitted by the SUT on all VCCs to verify connectivity and load. If the count on the test device is the same on the SUT, continue the test; else lower the test device traffic rate until the counts are the same.
4) 统计SUT在所有VCC上传输的IP数据包，以验证连接和负载。如果测试设备上的计数与SUT上的计数相同，则继续测试；否则，降低测试设备通信速率，直到计数相同。
5) Record the packets timestamps at the transmitter and receiver ends of the test device for all VCCs.
5) 在所有VCC的测试设备的发射器和接收器端记录数据包时间戳。

Procedure:
程序：
1) Set up the SUT and test device using the bi-directional configuration.
1) 使用双向配置设置SUT和测试设备。
2) Configure the SUT and test device with the maximum number of VCCs supported on the SUT. For example, if the maximum number of VCCs supported on the SUT is 1024, define 256 VPIs with 4 VCIs per VPI. The VCC's MUST be configured as either a CBR, VBR, or UBR connection. The VPI/VCIs MUST not be one of the reserved ATM signaling channels (e.g., [0,5], [0,16]).
2) 使用SUT上支持的最大VCC数配置SUT和测试设备。例如，如果SUT上支持的VCC的最大数量为1024，则定义256个VPI，每个VPI 4个VCI。VCC必须配置为CBR、VBR或UBR连接。VPI/VCI不得是保留的ATM信令信道之一（例如，[0,5]、[0,16]）。
3) Send a specific number of IP packets at a specific constant rate through the SUT via the defined test VCCs. All of the VPI/VCI pairs will generate traffic at the same traffic rate. Since this test is not a throughput test, the rate should not be greater than 90% of line rate. The IP PDUs MUST be encapsulated in AAL5.
3) 通过定义的测试VCC，通过SUT以特定的恒定速率发送特定数量的IP数据包。所有VPI/VCI对将以相同的流量率生成流量。由于该测试不是吞吐量测试，因此速率不应大于线路速率的90%。IP PDU必须封装在AAL5中。
4) Count the IP packets that are transmitted by the SUT on all VCCs to verify connectivity and load. If the count on the test device is the same on the SUT, continue the test; else lower the test device traffic rate until the counts are the same.
4) 统计SUT在所有VCC上传输的IP数据包，以验证连接和负载。如果测试设备上的计数与SUT上的计数相同，则继续测试；否则，降低测试设备通信速率，直到计数相同。
5) Record the number of CRC errored cells received per VCC on the test device.
5) 在测试设备上记录每个VCC接收到的CRC错误单元数。

Notes: 1. PDU size in cells is computed based on ceiling( ( PDU size in octets + 16) / 48). This assumes an 8 octet LLC/SNAP header and an 8 octet AAL/5 trailer.
注：1。单元中的PDU大小根据上限计算（（八位字节中的PDU大小+16）/48）。这假设一个8八位组LLC/SNAP头和一个8八位组AAL/5拖车。
2. Due to the number of possible configurations, IMA pps rates are not listed, but may be derived from the following formula: floor (IDCR/cells per packet), where cells per packet is computed as in note 1.
2. 由于可能的配置数量，未列出IMA pps速率，但可以从以下公式得出：floor（IDCR/每个数据包的小区数），其中每个数据包的小区数按注释1计算。
3. The following cell rates were used: DS-1 = 3622 cps (using ATM TC) E1 = 4681 cps 25.6 Mb/s = 60377 cps E3 = 80000 cps (using ATM TC) DS-3 = 104266 cps (using ATM TC) OC-3c = 353207 cps OC-12c = 1412828 cps
3. 使用了以下信元速率：DS-1=3622 cps（使用ATM TC）E1=4681 cps 25.6 Mb/s=60377 cps E3=80000 cps（使用ATM TC）DS-3=104266 cps（使用ATM TC）OC-3c=353207 cps OC-12c=1412828 cps
