Peer-to-peer (P2P) traffic dominates the Internet (Parker, 2005) and the P2P service Skype dominates global VoIP. This paper is an introduction to IP overlay networks and P2P applications, such as are used for content distribution and communications. P2P SIP is the standards based approach for P2P communications. The main design features of P2P SIP networks are presented along with interesting usage scenarios that would be difficult to implement with client-server (CS) SIP systems. The properties of P2P communications, security and control issues are described. P2P communications are the opposite to complex infrastructure based Voice over IP (VoIP) and multimedia systems such as IMS and TISPAN and may render them largely obsolete for reasons of cost, complexity and ease of innovation at the edge of the network.
这个嘛,去数据库吧。一般高校肯定有比较有名的数据库使用权限。找英文资料,通信方面的,自然是IEEE数据库啦,用关键词搜索,文章很多的,挑个差不多的就行了。
