The large use of P2P systems gives rise to the question of the performance of these applications. The performance evaluation of P2P systems can be undertaken in many ways. Here, we focus mainly on file retrieval performance, i.e., the time to download a file, the throughput of downloads and the waiting time before the transfer begins. Our study is based on(More)
While networks capacities are usually planned to cope with the offered traffic, transient link overloads may occur due to link failures or traffic peaks. According to previous analytical and simulation studies, performance degradation is relatively slow at moderate overloads. The reason is the high variance of the current flow size distribution. We check(More)
