1. Introduction
1. 介绍

Microwave radio is a technology that uses high-frequency radio waves to provide high-speed wireless connections that can send and receive voice, video, and data information. It is a general term used for systems covering a very large range of traffic capacities, channel separations, modulation formats, and applications over a wide range of frequency bands from 1.4 GHz up to and above 100 GHz.

微波无线电是一种利用高频无线电波提供高速无线连接的技术,可以发送和接收语音、视频和数据信息。它是一个通用术语,用于覆盖非常大范围的业务容量、信道分离、调制格式以及从1.4 GHz到100 GHz及以上的频带范围内的应用的系统。

The main application for microwave is backhaul for mobile broadband. Those networks will continue to be modernized using a combination of microwave and fiber technologies. The choice of technology depends on fiber presence and cost of ownership, not capacity limitations in microwave.

微波的主要应用是移动宽带的回程。这些网络将继续采用微波和光纤技术相结合的方式实现现代化。技术的选择取决于光纤的存在和拥有成本,而不是微波的容量限制。

Today, microwave is already able to fully support the capacity needs of a backhaul in a radio access network and will evolve to support multiple gigabits in traditional frequency bands and more than 10 gigabits in higher-frequency bands with more bandwidth. Layer 2 (L2) Ethernet features are normally an integrated part of microwave nodes, and more advanced L2 and Layer 3 (L3) features will be introduced over time to support the evolution of the transport services that will be provided by a backhaul/transport network. Note that wireless access technologies such as 3/4/5G and Wi-Fi are not within the scope of this document.

今天,微波已经能够完全支持无线接入网络中回程的容量需求,并将发展到在传统频带中支持多个千兆位,在更高频带中支持10个千兆位以上的带宽。第2层(L2)以太网功能通常是微波节点的集成部分,随着时间的推移,将引入更高级的第2层和第3层(L3)功能,以支持回程/传输网络提供的传输服务的发展。请注意,3/4/5G和Wi-Fi等无线接入技术不在本文档范围内。

Open and standardized interfaces are a prerequisite for efficient management of equipment from multiple vendors, integrated in a single system/controller. This framework addresses management and control of the radio link interface(s) and their relationship to other interfaces (typically, Ethernet interfaces) in a microwave node. A radio link provides the transport over the air, using one or several carriers in aggregated or protected configurations. Managing and controlling a transport service over a microwave node involves both radio link and packet transport functionality.

开放和标准化的接口是有效管理来自多个供应商、集成在单个系统/控制器中的设备的先决条件。该框架解决了微波节点中无线链路接口的管理和控制及其与其他接口(通常为以太网接口)的关系。无线链路使用聚合或受保护配置中的一个或多个载波提供空中传输。通过微波节点管理和控制传输服务涉及无线链路和分组传输功能。

Today, there are already numerous IETF data models, RFCs, and Internet-Drafts with technology-specific extensions that cover a large part of the L2 and L3 domains. Examples include IP Management [RFC8344], Routing Management [RFC8349], and Provider Bridge [IEEE802.1Qcp]. These are based on the IETF YANG data model for Interface Management [RFC8343], which is an evolution of the SNMP IF-MIB [RFC2863].

今天,已经有许多IETF数据模型、RFC和Internet草案,其中包含技术特定的扩展,覆盖了L2和L3领域的大部分。示例包括IP管理[RFC8344]、路由管理[RFC8349]和提供商网桥[IEEE802.1Qcp]。这些是基于IETF接口管理数据模型[RFC8343],它是SNMP IF-MIB[RFC2863]的一种改进。

Since microwave nodes will contain more and more L2 and L3 (packet) functionality that is expected to be managed using those models, there are advantages if radio link interfaces can be modeled and managed using the same structure and the same approach. This is

由于微波节点将包含越来越多的L2和L3(数据包)功能,预计将使用这些模型进行管理,因此,如果可以使用相同的结构和方法对无线链路接口进行建模和管理,则具有优势。这是

especially true for use cases in which a microwave node is managed as one common entity that includes both the radio link and the L2 and L3 functionality, e.g., basic configuration of the node and connections, centralized troubleshooting, upgrade, and maintenance. All interfaces in a node, irrespective of technology, would then be accessed from the same core model, i.e., [RFC8343], and could be extended with technology-specific parameters in models augmenting that core model. The relationship/connectivity between interfaces could be given by the physical equipment configuration. For example, the slot where the Radio Link Terminal (modem) is plugged in could be associated with a specific Ethernet port due to the wiring in the backplane of the system, or it could be flexible and therefore configured via a management system or controller.

尤其适用于微波节点作为一个公共实体进行管理的用例,该实体包括无线链路以及L2和L3功能,例如,节点和连接的基本配置、集中故障排除、升级和维护。一个节点中的所有接口,无论技术如何,都将从同一个核心模型(即[RFC8343])访问,并且可以在扩展该核心模型的模型中使用特定于技术的参数进行扩展。接口之间的关系/连通性可通过物理设备配置给出。例如,由于系统背板中的布线,插入无线电链路终端(调制解调器)的插槽可能与特定以太网端口相关联,也可能是灵活的,因此可通过管理系统或控制器进行配置。

There will always be certain implementations that differ among products, so it is practically impossible to achieve industry consensus on every design detail. It is therefore important to focus on the parameters that are required to support the use cases applicable for centralized, unified, multi-vendor management and to allow other parameters to either be optional or be covered by extensions to the standardized model. Furthermore, a standard that allows for a certain degree of freedom encourages innovation and competition, which benefits the entire industry. Thus, it is important that a radio link management model covers all relevant functions but also leaves room for product- and feature-specific extensions.

在不同的产品中总会有不同的实现方式,因此实际上不可能在每个设计细节上达成行业共识。因此,重要的是关注支持适用于集中、统一、多供应商管理的用例所需的参数,并允许其他参数可选或由标准化模型的扩展覆盖。此外,允许一定程度自由的标准鼓励创新和竞争,这有利于整个行业。因此,重要的是,无线链路管理模型涵盖所有相关功能,但也为特定于产品和功能的扩展留出空间。

Models are available for microwave radio link functionality: "Microwave Information Model" by the ONF [ONF-MW] and "Microwave Radio Link YANG Data Models" submitted to and discussed by the CCAMP Working Group [CCAMP-MW]. The purpose of this document is to reach

微波无线电链路功能可用模型:ONF[ONF-MW]的“微波信息模型”和CCAMP工作组[CCAMP-MW]提交并讨论的“微波无线电链路数据模型”。本文件旨在达到以下目的:

consensus within the industry around one common approach with respect to the use cases and requirements to be supported, the type and structure of the model, and the resulting attributes to be included. This document describes the use cases, requirements, and expected characteristics of the model. It also includes an analysis of how the models in the two ongoing initiatives fulfill these expectations and recommendations for what can be reused and what gaps need to be filled by a new and evolved model ("A YANG Data Model for Microwave Radio Link" by the IETF [IETF-MW]).

业界就一种通用方法达成共识,该方法涉及要支持的用例和需求、模型的类型和结构以及要包含的结果属性。本文档描述了模型的用例、需求和预期特性。它还包括对两个正在进行的计划中的模型如何满足这些期望和建议的分析,这些期望和建议涉及哪些可以重用,以及需要通过新的和改进的模型(“IETF[IETF-MW]提出的微波无线电链路的YANG数据模型”)填补哪些空白。

2. Terminology and Definitions
2. 术语和定义

Microwave radio: a term commonly used for technologies that operate in both microwave and millimeter wavelengths and in frequency bands from 1.4 GHz up to and beyond 100 GHz. In traditional bands, it typically supports capacities of 1-3 Gbps; in the 70/80 GHz band, it supports up to 10 Gbps. Using multi-carrier systems operating in frequency bands with wider channels, the technology will be capable of providing capacities of up to 100 Gbps.

微波无线电:通常用于微波和毫米波以及1.4GHz至100GHz及以上频段的技术的术语。在传统频段,它通常支持1-3 Gbps的容量;在70/80 GHz频段,它支持高达10 Gbps的速率。使用在更宽信道的频带中运行的多载波系统,该技术将能够提供高达100 Gbps的容量。

Microwave radio technology: widely used for point-to-point telecommunications because its small wavelength allows conveniently sized antennas to direct radio waves in narrow beams and its comparatively higher frequencies allow broad bandwidth and high data-transmission rates. It is used for a broad range of fixed and mobile services, including high-speed, point-to-point wireless local area networks (WLANs) and broadband access.

微波无线电技术:广泛用于点对点通信,因为它的波长小,可以方便地用大小合适的天线在窄波束中引导无线电波,而其相对较高的频率允许宽带和高数据传输速率。它用于广泛的固定和移动服务,包括高速、点对点无线局域网(WLAN)和宽带接入。

The ETSI EN 302 217 series defines the characteristics and requirements of microwave equipment and antennas. In particular, ETSI EN 302 217-2 [EN302217-2] specifies the essential parameters for the systems operating from 1.4 GHz to 86 GHz.

ETSI EN 302 217系列定义了微波设备和天线的特性和要求。具体而言,ETSI EN 302217-2[EN302217-2]规定了在1.4 GHz至86 GHz范围内运行的系统的基本参数。

Carrier Termination and Radio Link Terminal: two concepts defined to support modeling of microwave radio link features and parameters in a structured yet simple manner.

载波终端和无线链路终端:定义两个概念,以支持以结构化但简单的方式对微波无线链路特性和参数进行建模。

* Carrier Termination: an interface for the capacity provided over the air by a single carrier. It is typically defined by its transmitting and receiving frequencies.

* 载波终端:单个载波通过空中提供的容量接口。它通常由其发射和接收频率定义。

* Radio Link Terminal: an interface providing Ethernet capacity and/or Time Division Multiplexing (TDM) capacity to the associated Ethernet and/or TDM interfaces in a node. It is used for setting up a transport service over a microwave radio link.

* 无线链路终端:向节点中的相关以太网和/或TDM接口提供以太网容量和/或时分复用(TDM)容量的接口。它用于通过微波无线电链路建立传输服务。

Software-Defined Networking (SDN): an architecture that decouples the network control and forwarding functions, enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. SDN can be used for automation of traditional network management functionality using an SDN approach of standardized programmable interfaces for control and management [RFC7426].

软件定义网络(SDN):一种将网络控制和转发功能解耦的体系结构,使网络控制可以直接编程,并将底层基础设施抽象为应用程序和网络服务。SDN可用于传统网络管理功能的自动化,使用控制和管理标准化可编程接口的SDN方法[RFC7426]。

3. Approaches to Manage and Control Radio Link Interfaces
3. 管理和控制无线链路接口的方法

This framework addresses the definition of an open and standardized interface for radio link functionality in a microwave node. The application of such an interface used for management and control of nodes and networks typically varies from one operator to another in terms of the systems used and how they interact. Possible approaches include using a Network Management System (NMS), Software-Defined Networking (SDN), or some combination of the two. As there are still many networks where the NMS is implemented as one component/interface and the SDN controller is scoped to control-plane functionality as a separate component/interface, this document does not preclude either model. The aim of this document is to provide a framework for development of a common YANG data model for both management and control of microwave interfaces.

该框架解决了微波节点中无线链路功能的开放和标准化接口的定义。用于管理和控制节点和网络的此类接口的应用通常因运营商的不同而有所不同,具体取决于所使用的系统及其交互方式。可能的方法包括使用网络管理系统(NMS)、软件定义网络(SDN)或两者的某种组合。由于仍有许多网络,其中NMS作为一个组件/接口实施,SDN控制器作为一个单独的组件/接口控制平面功能,因此本文件不排除这两种模型。本文件的目的是为微波接口的管理和控制提供一个通用数据模型的开发框架。

3.1. Network Management Solutions
3.1. 网络管理解决方案

The classic network management solutions, with vendor-specific domain management combined with cross-domain functionality for service management and analytics, still dominate the market. These solutions are expected to evolve and benefit from an increased focus on standardization by simplifying multi-vendor management and removing the need for vendor- or domain-specific management.

经典的网络管理解决方案,包括特定于供应商的域管理,以及用于服务管理和分析的跨域功能,仍然主导着市场。通过简化多供应商管理并消除对供应商或特定领域管理的需求,这些解决方案有望发展并受益于对标准化的日益关注。

3.2. Software-Defined Networking
3.2. 软件定义的网络

One of the main drivers for applying SDN from an operator perspective is simplification and automation of network provisioning as well as end-to-end network service management. The vision is to have a global view of the network conditions spanning different vendors' equipment and multiple technologies.

从运营商的角度来看,应用SDN的主要驱动因素之一是网络供应的简化和自动化以及端到端网络服务管理。愿景是对跨越不同供应商设备和多种技术的网络状况有一个全局视图。

If nodes from different vendors are managed by the same SDN controller via a node management interface without the extra effort of introducing intermediate systems, all nodes must align their node management interfaces. Hence, an open and standardized node management interface is required in a multi-vendor environment. Such a standardized interface enables unified management and configuration of nodes from different vendors by a common set of applications.

如果来自不同供应商的节点由同一SDN控制器通过节点管理接口进行管理,而无需引入中间系统,则所有节点都必须对齐其节点管理接口。因此,在多供应商环境中需要一个开放和标准化的节点管理界面。这种标准化的接口可以通过一组通用的应用程序对来自不同供应商的节点进行统一的管理和配置。

In addition to SDN applications for configuring, managing, and controlling the nodes and their associated transport interfaces (including the L2 Ethernet, L3 IP, and radio interfaces), there are also a large variety of more advanced SDN applications that can be utilized and/or developed.

除了用于配置、管理和控制节点及其相关传输接口(包括二级以太网、三级IP和无线电接口)的SDN应用程序外,还可以利用和/或开发多种更高级的SDN应用程序。

A potentially flexible approach for operators is to use SDN in a logically controlled way, managing the radio links by selecting a predefined operation mode. The operation mode is a set of logical metrics or parameters describing a complete radio link configuration, such as capacity, availability, priority, and power consumption.

运营商潜在的灵活方法是以逻辑控制的方式使用SDN,通过选择预定义的操作模式来管理无线链路。操作模式是一组描述完整无线链路配置的逻辑度量或参数,如容量、可用性、优先级和功耗。

An example of an operation mode table is shown in Figure 3. Based on its operation policy (e.g., power consumption or traffic priority), the SDN controller selects one operation mode and translates that into the required configuration of the individual parameters for the Radio Link Terminals and the associated Carrier Terminations.

图3显示了操作模式表的示例。基于其操作策略(例如,功耗或业务优先级),SDN控制器选择一种操作模式,并将其转换为无线链路终端和相关载波终端的各个参数的所需配置。

If some part of the model is generic for other technology usage, it should be clearly stated.

Models are available for microwave radio link functionality: "Microwave Information Model" by the ONF [ONF-MW] and "Microwave Radio Link YANG Data Models" submitted to and discussed by the CCAMP Working Group [CCAMP-MW]. The analysis in this document takes these initiatives into consideration and makes a recommendation on how to use and complement them in order to fill the gaps identified.

For generic functionality, not functionality specific to radio link, the ambition is to refer to existing or emerging models that could be applicable for all functional areas in a microwave node.

对于通用功能,而不是特定于无线链路的功能,我们的目标是参考现有或新兴的模型,这些模型可能适用于微波节点中的所有功能区域。

6.1. Microwave Radio Link Functionality
6.1. 微波无线电链路功能

[ONF-CIM] defines a CoreModel of the ONF Common Information Model. An information model describes the things in a domain in terms of objects, their properties (represented as attributes), and their relationships. The ONF information model is expressed in Unified Modeling Language (UML). The ONF CoreModel is independent of specific data-plane technology. The technology-specific content, acquired in a runtime solution via "filled in" cases of specification, augments the CoreModel by providing a forwarding technology-specific representation.

[ONF-CIM]定义了ONF公共信息模型的核心模型。信息模型根据对象、对象的属性(表示为属性)及其关系来描述域中的事物。ONF信息模型用统一建模语言(UML)表示。ONF CoreModel独立于特定的数据平面技术。特定于技术的内容通过规范的“填充”案例在运行时解决方案中获得,通过提供特定于转发技术的表示来增强CoreModel。

IETF data models define implementations and protocol-specific details. YANG is a data modeling language used to model the configuration and state data. [RFC8343] defines a generic YANG data model for interface management that doesn't include technology-specific information. To describe the technology-specific information, several YANG data models have been proposed in the IETF to augment [RFC8343], e.g., the data model defined in [RFC8344]. The YANG data model is a popular approach for modeling interfaces for many packet transport technologies and is thereby well positioned to become an industry standard. In light of this trend, [CCAMP-MW] provides a YANG data model proposal for radio interfaces that is well aligned with the structure of other technology-specific YANG data models augmenting [RFC8343].

IETF数据模型定义了实现和特定于协议的细节。YANG是一种数据建模语言,用于对配置和状态数据进行建模。[RFC8343]为接口管理定义了一个通用数据模型,该模型不包括特定于技术的信息。为了描述特定于技术的信息,IETF中提出了几个数据模型来扩充[RFC8343],例如[RFC8344]中定义的数据模型。YANG数据模型是许多数据包传输技术接口建模的流行方法,因此很有可能成为行业标准。鉴于这一趋势,[CCAMP-MW]为无线电接口提供了一个YANG数据模型提案,该提案与其他技术特定的YANG数据模型的结构保持一致,以增强[RFC8343]。

[RFC3444] explains the difference between Information Models (IMs) and Data Models (DMs). An IM models managed objects at a conceptual level for designers and operators, while a DM is defined at a lower level and includes many details for implementers. In addition, the protocol-specific details are usually included in a DM. Since conceptual models can be implemented in different ways, multiple DMs can be derived from a single IM.

[RFC3444]解释了信息模型(IMs)和数据模型(DMs)之间的区别。IM在概念级别为设计人员和操作员建模托管对象,而DM在较低级别定义,并为实现人员提供许多详细信息。此外,特定于协议的详细信息通常包含在DM中。由于概念模型可以以不同的方式实现,因此可以从单个IM派生多个DM。

It is recommended to use the structure of the model described in [CCAMP-MW] as the starting point, since it is a data model providing the wanted alignment with [RFC8343]. To cover the identified gaps, it is recommended to define new leafs/parameters and include those in the new model [IETF-MW] while taking reference from [ONF-CIM]. It is also recommended to add the required data nodes to describe the interface layering for the capacity provided by a Radio Link Terminal and the associated Ethernet and TDM interfaces in a microwave node. The principles and data nodes for interface layering described in [RFC8343] should be used as a basis.

建议使用[CCAMP-MW]中描述的模型结构作为起点,因为它是一个数据模型,提供了与[RFC8343]所需的一致性。为了弥补已确定的差距,建议定义新的LEAF/参数,并在参考[ONF-CIM]的同时将其包括在新模型[IETF-MW]中。还建议添加所需的数据节点,以描述无线链路终端和微波节点中相关以太网和TDM接口提供的容量的接口分层。[RFC8343]中描述的接口分层原则和数据节点应作为基础。

6.2. Generic Functionality
6.2. 通用功能

For generic functionality, not functionality specific to radio links, the recommendation is to refer to existing RFCs or emerging Internet-Drafts according to Figure 4. "[IETF-MW]" is used in Figure 4 for the cases where the functionality is recommended to be included in the new model [IETF-MW] as described in Section 6.1.

对于通用功能,而不是特定于无线电链路的功能,建议参考图4中的现有RFC或新兴互联网草案。“IETF-MW]”在图4中用于建议将功能包括在第6.1节所述的新型号[IETF-MW]中的情况。

Figure 4: Recommendation for How to Support Generic Functionality

图4:关于如何支持通用功能的建议

Microwave-specific alarm configurations are recommended to be included in the new model [IETF-MW] and could be based on what is supported in the models described in [ONF-MW] and [CCAMP-MW]. Alarm notifications and synchronization are general and are recommended to be supported by a generic model, such as [YANG-ALARM].

建议在新型号[IETF-MW]中包括微波特定报警配置,并可基于[ONF-MW]和[CCAMP-MW]中所述型号中支持的配置。报警通知和同步是通用的,建议由通用模型(如[YANG-Alarm])支持。

Activation of interval counters and thresholds could be a generic function, but it is recommended to be supported by the new model [IETF-MW]. It can be based on the models described in [ONF-MW] and [CCAMP-MW].

激活间隔计数器和阈值可能是一种通用功能,但建议新型号[IETF-MW]支持该功能。它可以基于[ONF-MW]和[CCAMP-MW]中描述的模型。

Collection of interval/historical counters is a generic function that needs to be supported in a node. File-based collection via the SSH File Transfer Protocol (SFTP) and collection via NETCONF/YANG interfaces are two possible options; the recommendation is to include

间隔/历史计数器集合是节点中需要支持的通用函数。通过SSH文件传输协议(SFTP)进行基于文件的收集和通过NETCONF/YANG接口进行收集是两种可能的选择;建议包括:

support for the latter in the new model [IETF-MW]. The models described in [ONF-MW] and [CCAMP-MW] can also be used as a basis in this area.

在新型号[IETF-MW]中支持后者。[ONF-MW]和[CCAMP-MW]中描述的模型也可作为该领域的基础。

Physical and/or equipment inventory associated with the Radio Link Terminals and Carrier Terminations is recommended to be covered by a generic model for the complete node, e.g., the model defined in [RFC8348]. It is thereby outside the scope of the new model [IETF-MW].

建议完整节点的通用模型涵盖与无线链路终端和载波终端相关的物理和/或设备清单,例如[RFC8348]中定义的模型。因此,它超出了新型号[IETF-MW]的范围。

6.3. Summary
6.3. 总结

The conclusions and recommendations from the analysis can be summarized as follows:

分析得出的结论和建议可总结如下:

1. A new YANG data model for radio link [IETF-MW] should be defined with enough scope to support the use cases and requirements in Sections 4 and 5 of this document.

1. 无线电链路[IETF-MW]的新数据模型应具有足够的范围,以支持本文件第4节和第5节中的用例和要求。

2. Use the structure of the model described in [CCAMP-MW] as the starting point. It augments [RFC8343] and is thereby as required aligned with the structure of the models for management of the L2 and L3 domains.

2. 使用[CCAMP-MW]中描述的模型结构作为起点。它扩充了[RFC8343],因此根据需要与L2和L3域管理模型的结构保持一致。

3. Use established microwave equipment and radio standards (such as [EN302217-2], the model described in [CCAMP-MW], and the model described in [ONF-MW]) as the basis for the definition of the detailed leafs/ parameters to support the specified use cases and requirements, proposing new ones to cover identified gaps.

3. 使用已建立的微波设备和无线电标准(如[EN302217-2]、[CCAMP-MW]中描述的模型和[ONF-MW]中描述的模型)作为详细LEAF/参数定义的基础,以支持指定的用例和要求,并提出新的用例和要求,以弥补已确定的差距。

4. Add the required data nodes to describe the interface layering for the capacity provided by a Radio Link Terminal and the associated Ethernet and TDM interfaces, using the principles and data nodes for interface layering described in [RFC8343] as a basis.

4. 以[RFC8343]中描述的接口分层原理和数据节点为基础,添加所需数据节点,以描述无线链路终端和相关以太网和TDM接口提供的容量的接口分层。

5. Include support for configuration of microwave-specific alarms in the new YANG data model [IETF-MW] and rely on a generic model such as [YANG-ALARM] for notifications and alarm synchronization.

5. 在新的YANG数据模型[IETF-MW]中包括对微波特定警报配置的支持,并依靠[YANG-ALARM]等通用模型进行通知和警报同步。

6. Use a generic model such as [RFC8348] for physical/equipment inventory.

6. 使用[RFC8348]等通用模型进行物理/设备库存。

7. Security Considerations
7. 安全考虑

The configuration information may be considered sensitive or vulnerable in network environments. Unauthorized access to configuration data nodes can have a negative effect on network operations, e.g., interrupting the ability to forward traffic or increasing the interference level of the network. The status and inventory reveal some network information that could be very helpful to an attacker. A malicious attack to that information may result in a loss of customer data. Security issues concerning the access control to management interfaces can be generally addressed by authentication techniques providing origin verification, integrity, and confidentiality. In addition, management interfaces can be physically or logically isolated by configuring them to be only accessible out-of-band, through a system that is physically or logically separated from the rest of the network infrastructure. In cases where management interfaces are accessible in-band at the client device or within the microwave transport network domain, filtering or firewalling techniques can be used to restrict unauthorized in-band traffic. Additionally, authentication techniques may be used in all cases.

配置信息在网络环境中可能被视为敏感或易受攻击。未经授权访问配置数据节点可能会对网络操作产生负面影响,例如,中断转发流量的能力或增加网络的干扰级别。状态和清单显示了一些可能对攻击者非常有用的网络信息。对该信息的恶意攻击可能会导致客户数据丢失。有关管理接口访问控制的安全问题通常可以通过提供源验证、完整性和机密性的身份验证技术来解决。此外,通过将管理接口配置为只能在带外通过与网络基础设施的其余部分在物理上或逻辑上分离的系统访问,可以在物理上或逻辑上隔离管理接口。在客户端设备或微波传输网络域内的频带内可访问管理接口的情况下,可以使用过滤或防火墙技术来限制未经授权的频带内通信量。此外,认证技术可在所有情况下使用。

This framework describes the requirements and characteristics of a YANG data model for control and management of the radio link interfaces in a microwave node. It is supposed to be accessed via a management protocol with a secure transport layer, such as NETCONF [RFC6241].

该框架描述了用于控制和管理微波节点中无线链路接口的YANG数据模型的要求和特征。它应该通过具有安全传输层的管理协议进行访问,如NETCONF[RFC6241]。
