摘　　要：本文对P2P SIP抖动模型进行了初步研究。首先介绍P2P SIP系统的基本原理和存在的抖动问题。然后结合问题探讨了实验室环境下抖动模型的设计思路,重点围绕产生抖动现象的几个关键输入变量以及反映抖动对系统性能影响程度的几个典型输出变量,分析了抖动模型的设计过程;并基于可变输入量设计了两组测试例。最后给出了其测试结果数据,并基于对数据的处理和比较研究,初步分析了影响系统性能的几个量之间的关系,得出了基本结论。This document provides an research on the basic P2P SIP churn model.Firstly it introduces the basic principles of P2P SIP system and the presence of churn problem.Then it discusses some design ideas of churn test model,which focuses on several key input indexes that cause churn as well as a few typical output indexes that reflect the performance of P2P SIP system,and it analyzes the design process of churn model.It also describes some test cases base on the variable inputs in this document.and at the end it presents with the test results,and base on the data processing and comparison,it provides a preliminary analysis on the relationship of variables which effect system performance and approach some basic conclusions.
