A Research about Redundant Data Packet in Unstructured P2P Network

Peer-to-Peer systems depend on effective techniques to find and retrieve data; however, current techniques used in existing unstructured P2P system are often very inefficient because of the existence of large number of redundant messages. In this paper, we analyze the reason of engendering redundant data packet and put forward the Condensing Forward-List algorithm to reduce redundancy. Through experiments we find that it has good results. In addition, we design our algorithm to be simple, as a module that can be easily incorporated into existing unstructured P2P systems for immediate impact.
