Dynamic Multi-stream Transport Protocol

Legacy TCP is not suitable in high speed network environments due to its slow response time to high speed link bandwidth (large scale window size). A number of solutions have been proposed to support scalability under high link bandwidth. However, other criteria such as fairness and friendliness, in additional to scalability, should be considered. Accordingly, this paper describes a transport protocol for high speed networks, referred to as DMS-TCP, which uses multiple end-to-end streams simultaneously and considers scalability, fairness and friendliness simultaneously. DMS-TCP describes a scheme that controls the number of streams according to network condition. In this paper, the performance of DMS-TCP is evaluated through NS-2 simulation. The simulation results demonstrate that DMS-TCP can be used efficiently in high speed networks.
