An information sharing method among distributed peer activity management server on managing peer´s activities in MP2P network

Since P2P (Peer-to-Peer) technologies has been widely deployed, P2P-based applications produce tremendous traffic to Internet service providers. It is hard to predict traffic pattern since data is exchanged between peers. This leads to burden to the ISP on desiging network management plan. In order to solve problems caused by P2P application, there are several activities such as IETF ALTO and ISO MP2P Framework. IETF ALTO can provide underlying network information, and MP2P framework is capable of providing peer´s status and activity preferences that are gathered by PAMS. By the way, it is need to consider avoiding bottleneck problem that will be caused if many reports are concentrated into a server. In this paper, we describe a distributed peer activity management method and related issues to be resolved such as synchronization, procedures for server discovery, and procedures for probing remote peer´s status.
