Current TCP congestion control can be inefficient and unstable in high-speed wide area networks due to its slow response with a large congestion window. Several congestion control proposals have already been suggested to solve these problems and two properties have been considered: TCP friendliness and scalability, to ensure that a protocol does not take away too much bandwidth from TCP, while utilizing a bandwidth of high speed networks efficiently. In this paper, we propose a new variant of TCP for a high-speed network which combines delay-based congestion control with loss-based congestion control. Our simulation results show that proposed scheme performs better than the existing high-speed TCP protocols in terms of fairness, stability and scalability, while providing friendliness at the same time.
