Abstract
A variety of congestion control algorithms were proposed during the past two decades to make the greatest use of the network without congesting the bottleneck link, and they have raised the discussion of fairness and friendliness among flows in the bottleneck link. Meanwhile, large companies or clusters have considerable needs for shaping their own flows while maintaining friendliness to other flows in the network. This thesis proposes a novel cross flow congestion control scheme to achieve weighted fairness among flows owned by clusters and friendliness between those flows and network traffic. The control scheme can be applied to both window-based and rate-based congestion control algorithms, and it is implemented for TCP Cubic (window-based) and TFRC (rate-based).
We combine ns-3 simulation, emulation and Linux implementation to demonstrate the cross-flow control. Specifically, weighted fairness is achieved with a reasonable number of flows without losing the friendliness.
