This paper proposes using a modified TCP decoupling approach as a congestion control mechanism for optical burst switched networks. The TCP decoupling approach is a novel way that can apply TCP congestion control to any traffic flow (which can be an aggregate) in a network. Since this approach is generic, it has found applications in several areas. In the Optical Burst Switching (OBS) area, because the basic mechanism of the TCP decoupling approach matches the mechanism of the OBS very well, the authors propose using a modified TCP decoupling approach to congestion-control the traffic load offered to an OBS switch and regulate the timing of sending bursts.
