Overview:
This paper presents a novel network architecture, called Optical Burst Transport Network (OBTN), which can efficiently transport burst data over a virtual topology and reduce the port count of optical burst nodes. In OBTN nodes, bursts from attached optical feeder networks, e. g., metro networks, are multiplexed and transported to their egress OBTN node in one of two ways: preferably on direct end-to-end lightpaths set up between OBTN nodes or alternately on a relatively small number of hop-by-hop overflow burst wavelengths assigned to specific links which are shared among traffic flows.
