Abstract

In this paper, it presents an effective caching algorithm based on random access with the finite storage size in distributed server architecture for networked video services. Under the general video traffic condition, it is observed that the storage size and total popular contents of edge video server affect the performance of the total video sever system, and channel bandwidth between edge video servers and central video servers also is the key factor. To consider this fact, we design an effective edge caching algorithm to select the positions of content based on user random access in distributed server´s architecture. Finally, experimental results are provided to show the superior performance of the proposed algorithm.
