Solving Selfish Routing in Route-by-Name Information-Centric Network Architectures

Information-Centric Networking (ICN) is a promising network paradigm for the future Internet. As in the current Internet, selfish routing is also crucial problem in ICN. To the best of our knowledge, however, the selfish routing problem in ICN is remaining an unresolved challenge. To fill this gap, in this paper we propose a Nash Bargaining based content registration (NBREG) method, which is used for register content names (dissemination of content reachability information) from the game theoretic perspective. NBREG allows neighboring domains to cooperate with each other without revealing their internal private information. Based on results from real (inter-domain topology) trace simulations and prototype implementations, we show that neighboring domains can obtain more benefits with NBREG than they register and forward contents selfishly.
