Abstract
摘要
Multiprotocol Label Switching (MPLS), described in RFC 3031, is a method for forwarding packets that uses short, fixed-length values carried by packets, called labels, to determine packet next hops. A fundamental concept in MPLS is that two Label Switching Routers (LSRs) must agree on the meaning of the labels used to forward traffic between and through them. This common understanding is achieved by using a set of procedures, called a Label Distribution Protocol (as described in RFC 3036) , by which one LSR informs another of label bindings it has made. One such protocol, called LDP, is used by LSRs to distribute labels to support MPLS forwarding along normally routed paths. This document reports on a survey of LDP implementations conducted in August 2002 as part of the process of advancing LDP from Proposed to Draft Standard.
RFC 3031中描述的多协议标签交换（MPLS）是一种转发数据包的方法，该方法使用称为标签的数据包携带的短、固定长度值来确定数据包的下一跳。MPLS中的一个基本概念是，两个标签交换路由器（LSR）必须就用于在它们之间转发流量的标签的含义达成一致。通过使用一组称为标签分发协议（如RFC 3036中所述）的过程，一个LSR通知另一个LSR已进行的标签绑定，可以实现这一共识。LSR使用一种称为LDP的协议来分发标签，以支持MPLS沿正常路由路径转发。本文件报告了2002年8月进行的LDP实施情况调查，该调查是LDP从拟定标准推进到起草标准过程的一部分。

Multiprotocol Label Switching (MPLS) is a method for forwarding packets that uses short fixed-length values carried by packets, called labels, to determine packet next hops [RFC3031]. A fundamental MPLS concept is that two Label Switching Routers (LSRs) must agree on the meaning of the labels used to forward traffic between and through them. This common understanding is achieved by using a set of procedures by which one LSR informs another of label bindings it has made.
多协议标签交换（MPLS）是一种转发数据包的方法，它使用数据包携带的短固定长度值（称为标签）来确定数据包的下一跳[RFC3031]。MPLS的一个基本概念是，两个标签交换路由器（LSR）必须就用于在它们之间转发流量的标签的含义达成一致。这一共识是通过使用一组程序实现的，通过这些程序，一个LSR通知另一个LSR已进行的标签绑定。
Label Distribution Protocol (LDP) specifies a set of procedures LSRs use to distribute labels to support MPLS forwarding along normally routed paths. LDP was specified originally by [RFC3036]. The current LDP specification is [RFC5036], which obsoletes [RFC3036]. [RFC3037] describes the applicability of LDP.
标签分发协议（LDP）指定了LSR用于分发标签以支持MPLS沿正常路由路径转发的一组过程。LDP最初由[RFC3036]指定。当前LDP规范为[RFC5036]，淘汰了[RFC3036]。[RFC3037]描述了LDP的适用性。
This document reports on a survey of LDP implementations conducted in August 2002 as part of the process of advancing LDP from Proposed to Draft standard.
本文件报告了2002年8月进行的LDP实施情况调查，该调查是LDP从拟定标准推进到起草标准过程的一部分。
This section highlights some of the survey results. Section 2 presents the survey results for LDP features, and Appendix A presents the survey results in full. Appendix B contains a copy of the survey form.
本节重点介绍了一些调查结果。第2节给出了LDP特性的调查结果，附录A给出了完整的调查结果。附录B包含调查表的副本。
The LDP implementation survey requested the following information about LDP implementation:
自民党执行情况调查要求提供关于自民党执行情况的以下信息：
- Responding organization. Provisions were made to accommodate organizations that wished to respond anonymously.
- 响应组织。已作出规定，以容纳希望匿名回应的组织。
- The status, availability, and origin of the LDP implementation.
- LDP实施的状态、可用性和来源。
- The LDP features implemented and for each whether it was tested against an independent implementation. The survey form listed each LDP feature defined by [RFC3036] and requested one of the following as the status of the feature:
- 实现的LDP功能以及每个功能是否针对独立的实现进行了测试。调查表列出了[RFC3036]定义的每个LDP特征，并要求以下一项作为特征的状态：
t: Tested against another independent implementation y: Implemented but not tested against independent implementation n: Not implemented x: Not applicable to this type of implementation
t:针对另一个独立实现进行测试y:已实现但未针对独立实现进行测试n:未实现x:不适用于此类型的实现
In addition, for the 'n' status, the responder could optionally provide the following additional information:
此外，对于“n”状态，响应者可以选择提供以下附加信息：
s: RFC specification inadequate, unclear, or confusing u: Utility of feature unclear r: Feature not required for feature set implemented
s:RFC规范不充分、不清楚或令人困惑u:feature的实用性不清楚r:feature set实现时不需要feature
This document uses the following conventions for reporting survey results for a feature:
本文档使用以下约定报告要素的调查结果：
At By Cn indicates:
Cn的At表示：
- A responders implemented the feature and tested it against another independent implementation (t) - B responders implemented the feature but have not tested it against an independent implemented (y) - C responders did not implement the feature (n)
- A响应者实现了该功能并针对另一个独立实现进行了测试（t）-B响应者实现了该功能但未针对独立实现进行测试（y）-C响应者未实现该功能（n）
(Ds Eu Fr) indicates optional responses:
（Ds Eu Fr）表示可选响应：
- D responders thought the RFC 3036 specification of the feature inadequate, unclear, or confusing (s). - E responders thought the utility of the feature unclear (u). - F responders considered the feature not required for the feature set implemented (combines x and r).
- D响应者认为RFC 3036特征规范不充分、不清楚或令人困惑E响应者认为该功能的效用不明确（u）。-F响应者认为所实现的功能集不需要该功能（结合x和r）。
This section presents some highlights from the implementation survey.
本节介绍实施调查的一些要点。
- There were 12 responses to the survey, 2 of which were anonymous. At the time of the survey, 10 of the implementation were available as products and 2 were in beta test. Eleven of the implementations were available for sale; the remaining implementation had been done by a company no longer in business.
- 调查共有12份回复，其中2份是匿名回复。在进行调查时，10个实现作为产品提供，2个处于测试阶段。其中11种实现可供出售；其余的实施由一家不再营业的公司完成。
- Seven implementations were independently written from the RFC 3036 specification. Four implementations combined purchased or free code with code written by the responder.
- 七个实现独立于RFC3036规范编写。四种实现将购买的或免费的代码与响应者编写的代码结合起来。
One of the implementations was fully purchased code ported to the vendor's platform.
其中一个实现是完全购买的代码，并移植到供应商的平台。
- Every LDP feature in the survey questionnaire was implemented by at least 2 respondents.
- 调查问卷中的每个LDP特征均由至少2名受访者实施。
- Each of the 8 LDP Label Distribution Modes implemented and tested:
- 实施和测试的8种LDP标签分发模式中的每种：

LDP Implementation Survey Form (V 1.0)
LDP实施情况调查表（V1.0）
The purpose of this form is to gather information about implementations of LDP as defined by RFC 3036. The information is being requested as part of the process of advancing LDP from Proposed to Draft Standard.
本表格的目的是收集有关RFC 3036定义的LDP实现的信息。要求提供这些信息是将LDP从拟定标准推进到标准草案过程的一部分。
The form is patterned after the implementation report form used for HTTP/1.1; see:
