Abstract
Optical burst switching(OBS) is a potential technology to construct next generation all-optical networks
while its blocking performance becomes very poor in heavy load cases and network parameters are difficult to be designed.A novel time-slot optical burst switching networks architecture was intraduced in this paper.Based upon the comparison of conventional OBS networks
we present the mechanism of its control plane and corresponding functional units.The scheduling problem for network intermediate nodes was defined and slot assignment strategy was also discussed.Four on-line scheduling algorithms applied in network edge and core nodes are evaluated by simulation.
