A Novel Transport Protocol Suitable for Bufferless Optical Packet Switching Networks

In bufferless Optical packet switching (OPS) network, packet loss occurs when multiple packets arrive at the output port in relay node at the same timing even if there is no congestion. We propose a novel paradigm of transport protocol which has mechanism to autonomously control the burst transmission timing and interval. Differently from a large number of conventional modifications of TCP, such as congestion avoidance mechanisms, window control mechanisms, pacing mechanisms and so on, our proposal completely keeps burst packets transfer every constant time interval determined in a per-flow stepwise manner. Extensive simulation results confirmed that our proposal attains more than 7.0 times larger network throughput compared to conventional TCP.
