© 2015 ACM.This paper proposed a distributed packet scheduling algo-rithm for live peer-To-peer streaming system, where network coding is extended to improve the efficiency in bandwidth utilization. A problem of superuous packet transmission due to the lack of synchronization among peers is identi-filed. This problem often leads to bandwidth inefficiencies. We solve the problem of finding a suitable asynchronous packet scheduling policy by posing and solving a bandwidth allocation problem. This proposed scheduling policy can re-duce the superuous packet transmission, thereby achieving a more efficient bandwidth usage and an improved quality of service in live streaming applications. Experimental results confirm that the proposed scheme demonstrates significantly better video quality, delivery ratio under different network size and different loss rate compared with other push-based schemes.
