A Rate-based Congestion Control Method for NDN using AIMD and Explicit Rate Notification

摘要

In this paper, we propose a new rate-based congestion control method for Named Data Networking (NDN) using additive increase multiplicative decrease (AIMD) and explicit rate notification. In the proposed method, routers notify consumers of bottleneck bandwidth using Data packets, In addition, routers check congestion status using leaky bucket. If they detect congestion, they notify report it to consumers using negative acknowledgment (NACK) packets. A consumer sets its Interest sending rate to the reported rate, and adjusts the sending rate around the reported rate based on the AIMD mechanism. Through computer simulations, the proposed method achieves a high throughput performance and max-min fairness as a result of the effective congestion avoidance.
