Information-Centric Networking Cache Placement Method Based on Cache Node Status and Location

Information-Centric Networking with caching is a very promising future network architecture. The research on its cache deployment strategy divided into three categories, namely, noncooperative cache, explicit collaboration and implicit cache. Noncooperative can cause problems such as high content repetition rate in the web space. Explicit generally reflects best effect but requires lot of communication to satisfy exchange node information depends controller perform calculation. On this basis, cooperative reduce calculation between nodes while maintaining good effect. Therefore, paper proposes an on-path method based dynamic LRU-K replacement strategy. This evaluates their location state selects value transmission path for caching. Each request will only select one or two redundancy data. Simulation experiments show that improve hit average length.
