Cooperative cache sharing among ISPs for reducing inter-ISP transit cost in content-centric networking

Abstract (in Japanese) (See Japanese page) 
(in English) Content-Centric Networking (CCN) has an in-network caching mechanism, which can suppress traffic volume along the route to the destination host. This traffic volume reduction can also decrease inter-ISP transit cost. However, the memory spaces for caching at CCN routers are relatively small for the amount of contents. In addition, any initial access to a content requested by users must use the transit link, even when nearby CCN routers outside the route has the cached content. In this report, we propose a method of cooperative cache sharing among CCN routers in multiple ISPs. It aims to lead the further reduction in the inter-ISP transit cost by improving the cache hit ratio. In the proposed method, the CCN routers share the memory space for caching and cache contents without overlapping. We evaluate the proposed method by simulation experiments using the actual ISPs' IP-level network topologies, and show that the inter-ISP transit traffic can reduce by up to 28% compared to the normal caching behavior of the CCN.
