A Stage-Based Congestion Notice Strategy on TCP over OBS
Chunyan Liu · Computer Technology and Development · 2008
Traditional TCP congestion control algorithm mainly aimed at packets based communication network,when it is implemented in OBS network there will be series of new problems and may even degrade the performance of the OBS network.A three-stage-indication method is first proposed to improve congestion situations of TCP traffic in an OBS network.The technology can randomly mark different TCP flows in OBS border router in order to avoid congestion.It can not only respond quickly when congestion occurs,but also detect the false time-out phenomena,and therefore lead to better performance of the OBS network.
