CANR: Cache-Aware Name-based Routing

In the efforts to study the next generation of Internet, several Information Centric Networking (ICN) architectures, such as DONA, TRIAD and NDN, which focus on named data rather than named host, are proposed to facilitate content delivery (the primary usage of today´s Internet). In such networks, content may be dynamically cached in routers (i.e., in-network caching) and the same content may appear in multiple locations, and thus routers may serve users´ requests with nearby copies(either cached or replicated) instead of routing them to remote content publishers, which improves packet delivery performance as well as saves bandwidth. This work poses an open question that whether a Cache-Aware Name-based Routing (CANR) system that introduces cache-awareness in its control plane could be built so that in-network caches can be utilized in a more efficient and policy-compliant way. We explore the assumptions and goals that such a routing system should establish, make the problem concrete in NDN networking, dig into literature on related subjects, and propose an initial solution that serves as a catalyst.
