| 摘 要： | 以PPLive为代表的各种P2P多媒体应用的兴起给因特网带来了巨大的负担,为了解决它所造成的网络管理和维护的困难,从深入分析PPLive通信协议入手,根据其节点信息报文的格式构造爬虫程序从而获取当前网络中PPLive节点的地址和端口信息,并基于爬虫提出了一个分布式的PPLive流实时检测系统.通过试验对系统检测方法的正确性以及实时性进行了测试.试验结果表明,该系统能够准确和高效地检测出网络中的PPLive流.

| Abstract: | Represented by PPLive, popularity of mult imedia has brought great bur den on Inter net . In order
to solve the t ro ubles in netw or k manag ement and maintenance, the PPLiv e communicat ion protocol
w as analy zed. A craw ler was constr ucted acco rding to the peer info rmat io n packet to o btain IP address and
po rt of PPLive peers in netw or k current ly . Based on craw ler , a dist ributed r eal-t ime ident if icat ion sy stem
w as presented. T he cor rectness and real-time feature of the ident ificat ion method w ere tested. The result
of ex periment indicates that the system can ident ify the PPLive ex act ly and eff icient ly . |
