One of the crucial building blocks for Information Centric Networking (ICN) is a name based routing scheme that can route directly on content names instead of IP addresses. However, moving the address space from IP addresses to content names brings scalability issues to a whole new level, due to two reasons. First, name aggregation is not as trivial a task as the IP address aggregation in BGP routing. Second, the number of addressable contents in the Internet is several orders of magnitude higher than the number of IP addresses. With the current size of the Internet, name based, anycast routing is very challenging specially when routing efficiency is of prime importance. We propose a novel name-based routing scheme (αRoute) for ICN that offers efficient bandwidth usage, guaranteed content lookup and scalable routing table size.

We propose a name-based routing scheme α Route for ICN that offers efficient bandwidth usage, guaranteed content lookup and scalable routing table size. αRoute consists of two components: an alphanumeric Distributed Hash Table (DHT) and an overlay to underlay (Internet topology) mapping algorithm. Simulation results show that αRoute performs significantly better than Content Centric Network (CCN) in terms of network bandwidth usage, lookup latency and load balancing.

The concept of information-centric networking (ICN) defines a new communication model that focuses on what is being exchanged rather than which network entities are exchanging information. From the ICN perspective, contents are first class network citizens instead of hosts. ICN's primary objective is to shift the current host-oriented communication model toward a content-centric model for effective distribution of content over the network. In recent years this paradigm shift has generated much interest in the research community and sprung several research projects around the globe to investigate and advance this stream of thought. Content naming and content-based routing are core research challenges in this research community. In this survey, we analyze, compare, and contrast the naming and routing mechanisms proposed by some of the most prominent ICN research projects.
