Qualitative study of TCP NewRAPID
Nopporn Kongwatmai, Kultida Rojviboonchai · 2012
In this paper, we further evaluate our previously-proposed NewRAPID by comparing with TCP CUBIC and TCP RAPID in the following aspects: intra-protocol fairness, inter-protocol fairness, and convergence time. The result shows that TCP CUBIC provides more intra-protocol fairness than others because of its stability characteristic while TCP RAPID and TCP NewRAPID provide almost the same. Our designed stability enhancement makes TCP NewRAPID provide the best fair share when operating with TCP NewReno in inter-protocol scenario. Lastly, when an available bandwidth changes, TCP RAPID and TCP NewRAPID can converge faster than TCP CUBIC. This has been known as a characteristic of delay-based protocols.
