网络监测系统中SIP监测模块的研究与实现

Research and implementation of SIP monitoring system in network monitoring system

为了对实现对NGN网络的建设和优化,需要一种对网络中传输的信令消息进行分析的监测系统。本文以方案思想—设计实现—结果分析为线索,首先对监测系统设计思想进行研究,然后对信令测试仪中SIP监测模块进行了详细分析。在分析SIP协议消息结构的基础上,提出了SIP协议监测的方案,并给出了SIP类的定义体和SIP协议消息解码模块流程图。在SIP解码的基础上对监测模块中最重要的CDR合成模块进行了讨论,通过实际工程测试给出合成CDR结果,从而验证了监测系统方案的可行性与可靠性。

For building and optimization of network,we need monitoring System which can analyze Signaling messages in communication network.Following the clue：＂construction idea--designrealization--resultanalysis＂,we first research the design theory of monitoring system,then elaborate SIP monitoring module.According to the structure of SIP protocol,we propose the SIP Monitoring proposal ,SIP class definition body and decoding flowchart.Based on SIP decoding,we discuss the CDR module.Finally,we confirmed that the SIP module is reliable and feasible by testing.
