Effective Content Management Technique Based on Cooperation Cache among Neighboring Routers in Content-Centric Networking
Miho Aoki, Tetsuya Shigeyasu · 2017
Recently, ICN attracts the attention of network researchers. The ICN uses contents name as the ID for recognizing the communication partner instead of the traditional IP network using IP address (terminal location). Nowadays, the NDN which is the one of the network technology realizing the ICN policy, has been proposed. In NDN, routers consisting the backbone network collect the contents recent requested by users. By using NDN, users can obtain the desired contents from those routers caching the corresponding one. Hence, the network traffic induced by the user requests can be reduced significantly. However, the effects of the in-network caching on NDN will be largely influenced by the cache management algorithm. Currently, most researchers consider the LRU for the typical for the NDN. In the NDN, it is well known that the use of LRU induces the unfairness problem among the users. So, in this paper, we propose to cooperative cache management for increasing performance of cache hit ratio on NDN.
