CATT: Cache aware target identification for ICN

Abstract

The role of the Internet has been changed to a content oriented data sharing network. This new paradigm requires a major transformation of the current Internet architecture, which leads to the birth of the Information Centric Networking (ICN) concept in today's Internet. In this article, we propose an ICN architecture named Cache Aware Target identification (CATT) and introduce the architecture by focusing on two of its major components: routing and content caching. For each component of the CATT, Potential Based Routing (PBR) and topology aware caching policy are proposed respectively, and their cooperated operation is illustrated. Due to the synergy effect of both components, the CATT provides an efficient solution of content dissemination in the ICN environment.
