| Abstract: | Content delivery network is an internet application aiming to solve the response rate and improve the quality of service in recent years. Streaming media content deliver network is the application of streaming media technology in content delivery network. The cache strategy is the core algorithm in edge server proxy. So based on deep research on the current cache algorithms, this paper presents a new partial cache algorithm. This algorithm can obviously improve the system Concurrency, hit rate and Qos in practical project. |
