Abstract:
Named Data Networking (NDN) is a widely adopted future Internet architecture that focuses on large scale content retrieval. The congestion control is one of the hot research topics in NDN, and the rate-based congestion control method is considered to be well suited. From the viewpoint of implementation, however, the rate-based method has an issue that it requires the fine-grained clock management. This is hard to implement in off-the-shelf computers. This paper evaluates the performance in the case that consumers use a coarse-grained clock system. We use the Stateful Forwarding as a target, which is a rate-based method proposed by the group proposing NDN. The simulation results show that a coarse-grained clock system increases congestion. This paper also proposes a smooth Interest sending scheme under a coarse-grained clock system, which relieves congestion.
