Name-based routing for information centric future internet architectures

Information Centric Architecture has been proposed to overcome weaknesses of current Internet architecture. A number of research projects are exploring possible architectures for Future Internet (FI) based on Information Centric paradigm. There are number of challenges which needs to be addressed like Quality of Service provisioning, caching, scalability, trust management, security etc. Proposing an efficient and scalable routing solution for Information Centric Architecture is also a challenging research problem. The aim of this paper is to develop an understanding of the Information Centric Architectures and the problem of routing through a comparative analysis of existing solutions. We first outline the design challenges being faced by current Internet architecture which have motivated the need for new architecture for Internet followed by an overview of major Information Centric Architectures and name-based routing techniques proposed for them. We have classified the routing techniques for Information Centric Architectures into two main approaches i.e. distributed and centralized routing which either use DHT based or conventional IP like longest prefix matching solutions. Finally the paper outlines issues which need to be considered for finding the best solution for name-based routing.
