Performance analysis of VS nodes in TCP over optical burst switched multicast networks

This paper deals with multicast routing overhead for TCP over Optical Burst Switched Networks. This scheme is based on specialized nodes in All-Optical Networks (AONs) called as Virtual Source (VS) nodes. It aims at exploiting the capabilities of these nodes in order to reduce number of failed requests, thus reducing number of Burst retransmissions required. The architecture is simulated and proved effective with experimental results.
