WANG Jiang-tao, PENG Wei, GUAN Dong-liang. Optimal Cache Allocation of Streaming Video under Distributed Server Architecture[J]. 2011, 16(6): 104-108.DOI:
and fixed interval multicast is used in distributing popular videos under distributed server architecture where the remote server to local proxy server and local server to client connections are multicast capable.Based on the proposed transmission architecture
a closed form expressions is derived to determine the prefix cache allocation of each video on each local server so that the remote server bandwidth can be minimized.
