Abstract:
Content-Centric Network (CCN) is expected to become the network architecture in the future for exchanging content without specifying the addresses of nodes. An advantage of adopting CCN is that it improves the availability of network resources by using in-network caching. However, since servers that have a lot of popular content may suffer heavy traffic loads, which lead to frequent updates of caches in neighboring routers, the efficiency of cache usage may be degraded. To solve this problem, we propose a method for widely distributing content by using random encoded addresses. From our simulation results, we show that our method can reduce cache sizes by about up to 75% while still achieving the same cache hit ratio when the access frequencies are biased to a specific server.
