In this paper we present the GoalBit platform. GoalBit is the first open source peer-to-peer system for the distribution of real-time video streams through the Internet. The main advantage of a P2P architecture is the possibility of exploiting the available bandwidth unused by the set of user' hosts connected to the network. The main difficulty is that(More)
—This paper introduces a Combinatory Optimization Problem (COP) which captures the performance in cooperation of a P2P Streaming Network, considered at the buffer level. A new family of strategies of cooperation is defined, which represents the order of query of pieces in a communication between peers. We define a measure of quality for each strategy, based(More)
In this paper, a Cooperative Network Game (CNG) is introduced. In this game, all players have the same goal: display a video content in real time, with no cuts and low buffering time. Inspired in cooperation and symmetry, all players should apply the same strategy, resulting in a fair play. For each strategy we shall define a score, and the search of the(More)
The design of efficient protocols for mesh-based Peer-to-Peer (P2P) networks has many challenges, one of them is bandwidth allocation. On one hand, peers demand high Quality of Experience and network traffic when they watch their streaming contents. On the other, Internet Service Providers (ISPs) support their business with the capacity of their(More)
Peer-to-peer networks are strongly based on cooperation. The users, called peers, communicate basically in a three-level based policy. In the first one, peers discover others interested in the same content, and is called swarm selection strategy (or swarming). Then, peers must select the best ones to cooperate, what is called peer selection strategy.(More)
