Abstract

In this paper, the congestion control for named data networking (NDN) is studied. A novel dynamic content store-based congestion control strategy is proposed on account of the characteristic of in-network cache in NDN. A queuing network model is constructed to judge whether congestion occurs. If the network has the tendency of congestion or the congestion happened, the buffer of the output queue is dynamically expanded by borrowing NDN content store (CS), and the forwarding rates of data packets and corresponding interest packets are reduced so as to prevent or alleviate network congestion. In order to reflect fairness, the CS to be borrowed by the data output queue in the port is calculated in terms of the data output queue length and its weight. The simulation results based on ndnSIM show that the given scheme improves the bottleneck link utilization and maintains a low packet loss rate and average flow completion time.
一种基于公平动态内容存储的命名数据网络拥塞控制策略
本文研究了命名数据网络(NDN)的拥塞控制问题。针对NDN网络中网内缓存的特点,提出了一种基于动态内容存储的拥塞控制策略。构造了一个排队网络模型来判断是否发生拥塞。当网络有拥塞趋势或拥塞发生时,通过借用NDN内容存储(content store, CS)动态扩展输出队列的缓冲区,降低数据包和相应兴趣包的转发速率,从而防止或缓解网络拥塞。为了体现公平性,根据数据输出队列的长度及其权重计算端口内数据输出队列所要借用的CS。基于nnsim的仿真结果表明,该方案提高了瓶颈链路利用率,保持了较低的丢包率和平均流完成时间。
