Topology-awareness based latency minimizing data traffic optimized allocation algorithm

To solve the network bandwidth optimization problem of P2P media streaming, a topology-awareness based latency minimizing data traffic optimized allocation algorithm was proposed. By utilizing the knowledge of underlying topology, the algorithm divides the member peers of a P2P streaming system into bottleneck shared peers and non-bottleneck shared ones, and uses the weighted round-robin algorithm and the enumerative optimization algorithm separately to optimize the transmission performance. The simulation results show that the algorithm can reduce the duplicated data about to 70%~90%, and reduce the network delay of about 30%.
