Shared running cache algorithm with supporting video VCR operation
一种支持视频VCR操作的共享动态缓存算法

VCR operations are important functions of streaming media servers. Most of conventional caching algorithms implemented by media servers do not consider the impact of VCR operations. Based on the SRB algorithm and combining patching technology, a kind of shared cache algorithm named SRC-SV was proposed, which supported VCR operations. The simulation results show that the SRC-SV algorithm can be used to handle VCR operations and be effective in reducing consumption of server's load and backbone bandwidth.
