【摘要】 针对越来越多P2P语音、视频传输应用给底层网络造成巨大通信压力的问题,提出Skype网络拓扑测量方案,分析Skype协议、通信机制、流量及行为特征。通过分析大量主动获取的节点数据和被动获取的Skype通信流量,总结出Skype网络的通信机制,发现部分Skype网络的流量特征、协议行为特征,经测试,在局域网环境下,该项方案能有效识别、管理Skype流量。更多还原

【Abstract】 For the issue that more and more popular P2P voice and video transmission application cause great pressure for the underlyingcommunication network, this paper provides the scheme of measuring Skype network topology, and analyzes Skype protocols, communicationmechanism and traffic characteristics.Based on analyzing lots of active measuring experimental data and passive capturing communication traffic ofSkype, it provides the communication mechanism of Skype, and finds out partly traffic characteristics and protocol behavior characteristics ofSkype.Through tests, these conclusions can be used to analyze and control Skype in the LAN environment.更多还原
