Reliability analysis of Structured P2P System
Reliability is most important for structured p2p systems and how to exactly evaluate the metric-loss rate which is tightly related to reliability is a hot topic and challenge.Many research works of the loss rate only consider the situation that the loss rate is caused by next hop node failure (NF).Indeed,the lost of queuing message (QF) on the failure node also contribute to the loss rate.This paper presents an analytical model of loss rate caused by NF and NQ.In order to achieve the optimal performance of system through minimizing the NQ,we propose two methods:process power enhancing (PPE) and Space Partition (SP).In the heterogeneous systems,we can obtain the minimal loss rate via improving each nodes process power; in the homogeneous structured p2p systems,the partition space method can evenly partition the ID space so as to ensure the traffic load is uniformly distributed over all nodes.
