| 摘 要： | 测量分析P2P文件共享系统是解决P2P优化、网络管理等问题的基础。当前P2P网络设计日趋复杂,并且部分运行机制直接导致测量数据不完整或测量周期过长,比如BitTorrent文件共享系统。针对这一问题,本文抽象出BitTorrent系统的3个测量层次,包括索引测量、节点测量和内容测量,并重点解决了3个层次中的测量难题,设计实现了一个面向BitTorrent的测量系统。在此基础上,本文对BitTorrent系统进行了持续测量,并重点分析了BitTorrent系统的节点行为:节点演化规律和节点到达模型。测量结果表明,节点演化规律和节点到达均呈现强烈的周期性。为此,本文改进了节点到达模型,新模型与实际测量数据拟合效果较好,进一步修正了节点到达模型。

| Abstract: | Measuring and characterizing peer-to-peer file-sharing systems will benefit the optimization and management of P2P systems.The designs of current P2P network are getting more complicated,and several operational mechanisms bring about the incompleteness of data or long period in measurement,such as BitTorrent system.To solve the problem,three levels are abstracted from BitTorrent system in the view of measurement in this paper,including index,peer and content.Furthermore,this paper focuses on the difficult p... |
