We study the problem of maximizing the broadcast rate in peer-to-peer (P2P) systems under node degree bounds, i.e., the number of neighbors a node can simultaneously connect to is upper-bounded. The problem is critical for supporting high-quality video streaming in P2P systems and is challenging due to its combinatorial nature. In this paper, we address this problem by providing the first distributed...
Broadcasting systems such as P2P streaming systems represent important network applications that support up to millions of online users. An efficient broadcasting mechanism is at the core of the system design. Despite substantial efforts on developing efficient broadcasting algorithms, the following important question remains open: How to achieve the maximum broadcast rate in a distributed manner...
We consider a P2P multicast network with time- varying topology and node upload capacities. By utilizing network coding, we design a dynamic and distributed algorithm that can achieve arbitrarily close to maximum network utility while maintaining network stability. In addition, we show this algorithm can provide incentives for nodes to stay in the network and relay traffic for others even when they...
