Exploring Cache Coding Scheme for Information-centric Networking

The tremendous growth of the Internet application has driven wider efforts to advanced future Internet architecture especially Content-Centric Networking. In this paper we propose a Centralized Architecture for ICN (CAN), which efficiently combines Content-Centric Networking and network coding (NC). In order to achieve optimal coding performance, we design a global controller which is mainly responsible for calculating entire network routing tables and controlling optimal trade off among cache coding schemes. Specifically, we propose a coding chunk naming scheme and an efficient network coding management approach, which apply to recover the lost native content packets according to NC. Experiment results show that NC in CAN has a great performance for content packet loss recovery. In particular, it can reach nearly 100% recovery in sufferable packet loss rate. Meanwhile, the efficiency and performance of which are superior to the conventional CCN.
