Comparison of Migration Approaches of ICN/NDN on IP Networks

Named-based Internet architecture such as the Named Data Networking (NDN) and the Information-Centric Networking (ICN) have been developed rapidly. The current Internet architecture, TCP/IP, will be replaced by ICN/NDN in the next decades. However, it seems unrealistic to replace all the IP routers to ICN/NDN routers at the same time, so the migration process of the ICN/NDN routers over the Internet is unavoidable. Therefore, we should discuss the migration mechanism to realize the name-based Internet architecture. This paper depicts several mechanisms and approaches that have been written and reported in recent years. The advantages and disadvantages of each approach are also deeply discussed and explained. Finally, this paper gives a big picture and recommendation about the efficient way of migrating ICN/NDN routers on the Internet.
