This paper mainly studied on IPTV, which is paid most attention just behind 3G in the field of telecommunications in the world at present.

Impact of peers stochastic behaviors on file population in peer-to-peer network;

The design and implementation of computing engine in PC grid based on Peer-to-Peer Infrastructure;

Web Services in the Peer-to-Peer environment;

A novel authentication framework,which is named central identity-code assignment and distributed authentication(CIADA),is proposed in order to meet the demands of the secure authentication for nodes in the peer-to-peer(P2P) network.

A hierarchical P2P-SIP architecture was proposed based on the features of the existing Peer-to-Peer(P2P) applications and Session Initiation Protocol(SIP).

A Novel Peer to Peer Network Security Route Algorithm Based on Group;

The search method based on P2P(peer to peer) computing , which can significantly enhance the search efficiency compared with the traditional search method, provides a new way for researching the next generation search engine.

With the rapid development of computer network and the increasing processing ability of personal computer,Peer to Peer technology has attracted much attention for its new feature.

A trace of BitTorrent application traffic,which is the most popular P2P(peer-to-peer)application in China,is accurately captured using payload-based method.

In P2P(peer-to-peer),a kind of search mechanism based on topic partition is presented.

The fast development of P2P(peer-to-peer) also brings some problems such as the bandwidth shortage,internet piracy,and network security management etc.
