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, which is hard to implement in off-the-shelf computers. We focused this issue in our previous paper, and evaluated the performance in the case that consumers use a coarse-grained clock system. In this evaluation, we used the Stateful Forwarding as a target, which is a rate-based method proposed by the group proposing NDN. The simulation results showed that a coarse-grained clock system increases congestion. We also proposed a smooth Interest sending scheme under a coarse-grained clock system, which relieves congestion. However, our previous paper discussed only results with limited evaluation conditions, such as one consumer/producer pair configuration and a relatively low link speed. In this paper, we revisit the impact of system clock granularity of the performance of NDN rate based congestion control with practical evaluation conditions and with detailed analysis.
