Ratna Pavani. K, N. Sreenath . Evaluating the Burst Delivery Ratio of TCP Variants with Varying Burst Sizes and Offset Times in an all-Optical Burst Switching Network. International Journal of Computer Applications. 67, 10 ( April 2013), 9-12. DOI=10.5120/11429-6782
To protract next generation Internet, TCP over OBS is a potential transport paradigm. Since the popular variants of TCP were designed to work with IP networks, they behave differently over OBS networks. Packets from various IP sources assemble into a Data burst and it is transmitted from ingress node to egress node cutting through the core nodes all-optically. Data burst is always preceded by a control packet with an offset time. Owing to bufferless nature of OBS burst losses may occur due random contention. In this scenario an experimental study was made to evaluate the performance of two popular TCP variants, TCP-Reno and TCP-Vegas using NS-2.
