A Comparison of TCP-Friendly Congestion Control Protocols
Using the ns simulatior, the authors perform a detailed study of the fairness and the smoothness properties of SimdNR, an enhanced version of SIMD. The study includes TFRC and TCP congestion control protocols in both steady-state and highly dynamic network conditions through RED and DropTail routers. The results show that SimdNR is fair to TCP through RED routers in steady-state scenario. But, SimdNR is not fair to TCP over drop tail routers. Also the results show that SimdNR demonstrates less smoothness than TFRC in steady-state scenario and superior smoothness than TFRC in dynamic network conditions.
