Research of edge caching strategy based on collaboration mechanism

This paper introduces a collaboration mechanism in a multi-layered and centered network topology model to achieve the sharing and effective use of cache content through edge cache clusters. Under this network architecture, a collaborative cache deployment algorithm and a cache elimination strategy based on a multi-level popularity index are proposed, and a cache strategy evaluation mechanism with cache hit rate and content acquisition delay as evaluation indicators is established. Finally, the two are combined into a caching strategy based on a collaboration mechanism. Simulation experiments and comparative analysis are performed using the caching strategy evaluation mechanism. The experimental results show that the proposed caching strategy can effectively improve cache performance and service quality.
