Implementation and Evaluation of WBBR in ns-3 for Multipath Networks

Today’s networks carry a large amount of data, it is common for traffic to exceed the capacity of the network links, this event is called congestion. Therefore, the development of congestion control algorithms has become a key task in improving the performance of networks. BBR is a congestion control algorithm that continuously measures bottlenecks and RTT to establish the size of the congestion window. WBBR is an algorithm that incorporates a weighting factor to BBR to achieve fairness. The present work proposes an implementation of WBBR in ns-3 and performs a comparative evaluation with BBR since it has not been done before. The implemented module was validated with the previous results available in the literature. The results show that WBBR is fairer than BBR achieving load balancing, without increasing the RTT values.
