Abstract

In the congestion control algorithm, the round trip time (RTT) has been used as a key parameter to estimate the degree of network congestion However, RTT indicates the packet delays taken in both the forward path (from source to destination) and the backward path (from destination to source) Therefore, the congestion control algorithm based on RTT may falsely trigger the rate control due to the congestion built in the backward path In this paper, we propose a receiver-based congestion control algorithm in which the network condition is estimated by using the one-way trip time (OTT) By virtue of the use of OTT, the proposed algorithm can effectively decouple the forward path from the backward path when estimating the network congestion The simulation results confirm the effectiveness of the proposed algorithm.
