Abstract:
In-network caching technologies like Content-Centric Networking (CCN) are expected to reduce the network traffic and improve the service quality, such as communication latency, by storing content data on routers near to users. Meanwhile, the adaptive cache management using Time-To-Live (TTL) of content can realize efficient memory management per content. However, for a distributed cache system such as CCN, it is difficult to evaluate cache performance and network resources required in the cache mechanism using the TTL value. Therefore, we propose a theoretical model, which can analyze the impact of TTL-based caching on network resources and cache performance, and evaluate some scenarios using the proposed model. We finally introduce a cache mechanism using energy efficient TTLs and show its effectiveness by the model-based analysis.
