【摘要】：近年来,移动业务的中心从语音业务逐渐转移到数据业务,数据流量成倍增加,无线通信网络技术从2G往LTE不断演进升级,固定与移动业务在回传网中的融合成为了未来的趋势。伴随着传送网设备向IP无线接入网(IP Radio Access Network, IP RAN)的升级,如何对这些设备进行有效的管理是一大难题。本文首先介绍了网络管理的基本概念,对当前现有的网络管理技术作了简要说明,分析了目前网络管理技术中流行的编码方式。随后通过对比,引入了Protocol Buffers编码方式。本文从Protocol Buffers的数据类型、代码生成机制、编码原理等多方面做了分析,并将其与现有的网管技术结合在一起,设计了Protocol Buffers适配层。该适配层部署在控制平面,完成了传输适配、网管协议适配、数据适配和语义适配,在结构上划分为网管客户端、Protocol Buffers适配模块和协议栈客户端三个模块。本文详述了各个模块的工作原理、工作流程与模块间接口。最后,本文将适配层的设计方案在现有的IP RAN设备网络管理系统中进行部署,与设备的命令行接口(Command Line Interface, CLI)进行适配。实现了适配层各个模块的编码与模块间通信,通过单元测试验证了适配层各个模块的功能。
[Abstract]:In recent years, the center of mobile services has gradually shifted from voice services to data services, data traffic has multiplied, wireless communication network technology has been evolving from 2G to LTE, and the integration of fixed and mobile services in the backpass network has become a future trend. With the transmission network devices to IP wireless access network (IP Radio Access Network, IP RAN) In this paper, the basic concept of network management is introduced, and the current network management technology is briefly explained, and the popular coding methods in the current network management technology are analyzed. Then the Protocol Buffers encoding method is introduced through the comparison. This paper from Pr Otocol Buffers data types, code generation mechanism, coding principle and many other aspects are analyzed, and combined with existing network management technology, the Protocol Buffers adaptation layer is designed. The adapter layer is deployed in the control plane, completes transmission adaptation, network management protocol adaptation, data adaptation and semantic adaptation, and is structurally divided into network The client, the Protocol Buffers adapter module and the protocol stack client three modules. This article details the working principle of each module, the work flow and the intermodule interface. Finally, the design scheme of the adapter layer is deployed in the existing IP RAN network management system, and the Command Line Interface (Command Line Interface, CLI) adapts, realizes the encoding and inter-module communication of each module in the adapter layer, and verifies the function of each module in the adapter layer through unit test.
