Paper Abstract

Conventional approaches to QoS (Quality of Service) provisioning in IP networks are difficult to apply in all-optical networks. This is mainly because there is no optical RAM (Random Access Memory) to store packets during contention for bandwidth, so the provision of QoS with OBS (Optical Burst Switching) is a hot issue that has been widely studied. Most of the QoS schemes guarantee the performance of high priority traffic at the cost of low priority traffic's performance. To solve this problem, a novel wavelength assignment scheme for supporting QoS in OBS networks is proposed in this paper, we give the detailed means to increase the priority of the buffed low priority bursts and show it is especially beneficial to improve networks average throughput than that of offset-time-based scheme.
