ABSTRACT
Despite the growing popularity of live P2P continuous media transmission applications, still limited the current understanding of important aspects of the behavior of the participants, like the arrival time between them and time spent on the network. This work aims to fill this gap by presenting a characterization of the behavior of participants in SopCast, one of the most popular live transmission applications on P2P. The analysis includes properties for the session, such as gaps between the arrival of new participants, staying time, number of sessions and inactivity time between sessions. We also present properties of partnerships among participants, such as number of partners. In addition, the study deals with different SopCast channels, highlighting differences in patterns of behavior depending on content. The characterizations present a model set of participants, which can be used as a basis for creating new protocols and generation of realistic synthetic loads for live broadcast on P2P.

An experimental study of peer behavior in a pure P2P network
Abstract: Dynamic peer behavior in P2P networks has a large impact on the performance of the network because each peer acts simultaneously as a server and a client in an overlay network. However, peer behavior in pure P2P networks is not well known ...
