摘要：
Optical Burst Switching is a promising switching technology to exploit the potential benefits of optical communication for next generation optical networks. Edge nodes are able to support multiple priorities by assigning different offset time between control packets and data bursts. Data traffic having high priority is known to have better performance than that having low priority in terms of blocking probability. However, we found that the extra offset time-based QoS mechanism does not support the aforementioned benefits in viewpoint of TCP-level performance. Simulation results show the limitation of QoS support based on the extra offset-time.
