摘要:There are enormous types of traffic flows in the IoT era. The traffics could be control by Software Defined Network (SDN) or other transmission protocols in the core networks or mobile edge networks. TCP-BBR algorithm has a better performance on long-fat pipes than traditional TCP protocols in terms of link perception and response time. However, when TCP-BBR and other congestion control algorithms which are based on time delay like TCP-Westwood is applied to the same network links, TCP-BBR will perform unfriendly to the TCP-Westwood. Aiming to improve the fairness between TCP-BBR congestion control algorithm and delay-based congestion control algorithms, this paper proposes a congestion control algorithm based on TCP-BBR which has moderate fairness named Modest Fairness BBR(MFBBR). The simulation results on the Mininet show that our algorithm can improve the fairness of BBR when it coexists with Westwood, and it also has better fairness than delay-based congestion control algorithms.
