The free-riding problem is widely accepted to be retarding the deployment and growth of P2P networks. In order to solve this problem, we give a strict definition of the peer's contribution, utility and incentive reputation and model a P2P network with heterogeneous peers as an incomplete information static game.

With the rapid development of Web, dynamic and personalized web pages increase gradually. In order to deliver dynamic web pages more efficiently, researchers proposed some kinds of schemes. ESI (Edge Side Includes) and CDE (Class-based Delta-encoding) which classical techniques for efficient delivery of dynamic web pages are elaborated in this paper. Then, dynamic page classification is discussed,...
DDoS flows that do not cut down their sending rates after their packets are dropped will hog the buffer space at routers and deprive all other flows of their fair share of bandwidth. Based on the network behavior, this paper studies the defense mechanism of DDoS from the aspect of congestion control. And in the simulation environment of DDoS, this paper studies the RED (random early detection) algorithm...
