摘要：Using identifiers to address the member nodes at DHT based peer-to-peer (p2p) networks provides structured method of addressing the nodes. The node lookup is then used to find the equivalent communication address of a given identifier. One of the main concerns is how to find the communication addresses efficiently, especially if a node has joined or rejoined the network recently. In this paper an address propagation model has been proposed which is used as a solution in friend-to-friend (f2f) overlays at p2p networks. The model keeps the required communication addresses up-to-date in order to reduce the need of any node to perform the lookup process. It allows each node to maintain the addresses in a distributed manner using bucket based broadcasting and guarantees that it has the current up-to-date addresses of its friend nodes as a necessary information to establish a direct connection without any centralized scheme. Despite adding some traffic overhead to the network, the proposed address propagation process is secure and fast.
