An important problem that confronts P2P network is to efficiently search the node that stores a particular data. Chord is a distributed lookup protocol that addresses the problem. However, the chord protocol has not yet efficiently resolved the problem. In this paper an improved Chord algorithm is presented, which considers the node's actual ability, the physical location relationship, the routing...
Distance education resources based on P2P mode are distributed in each node, which is difficult to find target resource. In order to improve the efficiency of the distance education system resource utilization, the paper fully considers the node physical location and node ability, and puts forward an improved Chord mode on the base of the analysis of the Chord model principle. Then, the improved Chord...
