Abstract

Packet-level caching is difficult to implement in the traditional caching system. The emergence of information-centric networking has alleviated this problem. However, the packet-level caching is still facing severe scalability issues. This paper analyzed the issues which limited the implementation of packet-level caching and proposed a packet-level caching optimization approach. This scheme reduced the consumption of fast memory by creating the index with group prefixes instead of the packet prefixes, while also used the group-level popularity to optimize caching decision. This paper evaluated the performance of the scheme through extensive simulation experiments regarding a wide range of performance metrics. The experimental results indicate the scheme can reduce the fast memory usage and achieve significant improvement in terms of server load reduction ratio, average hop reduction ratio and average cache hit ratio, compared with current packet-level caching schemes.
