This paper proposes a novel stream sharing strategy named TPG-Patching,which based on the stream creating algorithm of Grace-Patching,the regular stream management algorithm of PeriodPatch,and the stream schedule strategy of Patching First.

• 为提高WanLan集群视频服务器的服务能力,基于Grace-Patching流生成策略、PeriodPatch主流管理算法和Patching First流调度策略,提出TPG-Patching流共享策略。
