Abstract

In recent years, Session Initiation Protocol (SIP) based Voice over IP (VoIP) based applications are alternative to the traditional Public Switched Telephone Networks (PSTN) because of its flexibility in the implementation of new features and services. The Session Initiation Protocol (SIP) is becoming a popular signaling protocol for Voice over IP (VoIP) based applications. The SIP Proxy server is a software application that provides call routing services by parsing and forwarding all the incoming SIP packets in an IP telephony network. The efficiency of this process can create large scale, highly reliable packet voice networks for service providers and enterprises. Since, SIP Proxy server performance can be characterized by its transaction states of each SIP session, we proposed the M/M/c performance model of the SIP Proxy Server and studied some of the key performance benchmarks such as server utilization, queue size and memory utilization. Provided the comparative results between the predicted results with the experimental results conducted in a lab environment.

基于M/M/c的SIP代理服务器排队模型的性能与可扩展性——一种实用方法

近年来，基于会话发起协议(SIP)的IP语音(VoIP)应用以其在实现新特性和新业务方面的灵活性取代了传统的公共交换电话网(PSTN)。会话发起协议(SIP)正在成为基于IP语音(VoIP)应用的一种流行的信令协议。SIP代理服务器是一种软件应用程序，它通过解析和转发IP电话网络中所有传入的SIP数据包来提供呼叫路由服务。该过程的效率可以为服务提供商和企业创建大规模、高可靠的分组语音网络。由于SIP代理服务器的性能可以通过每个SIP会话的事务状态来表征，我们提出了SIP代理服务器的M/M/c性能模型，并研究了服务器利用率、队列大小和内存利用率等关键性能基准。提供了预测结果与实验室环境下的实验结果的对比结果。
