Title:The Effects of Perturbation on Gnutella Network
Author(s):Ko, Steven Y.

Subject(s):Peer-to-Peer Systems
Network Monitoring
Abstract:It is well known that a user, who participates in an overlay network like Gnutella, does not stay in the network continuously, but goes online and offline repeatedly. In addition to this user behavior, dynamic network conditions like congestion, routing flaps in BGP, and intermittent router failures can force a node unavailable for a short period of time. This paper studies how Gnutella would perform under those stressful network environments caused either by the network itself or by the users of the overlay network. According to our results, Gnutella tolerates node perturbations well and shows even better performance when a small portion of nodes is perturbed. This behavior of Gnutella confirms the common belief that unstructured peer-to-peer systems can tolerate dynamic changes of the overlay topology.
