摘要：Optical Burst Switching (OBS) is a promising solution for all optical Wavelength Division Multiplexing (WDM) networks. It combines the benefits of both Optical Packet Switching (OPS) and Optical Circuit Switching (OCS). In this switching, data are transmitted in the form of bursts. Fairness is the main constraint in high-performance OBS network. In order to improve the fairness, a method known as hop-based burst-cluster transmission is used. In this method, bursts are assembled from smallest to largest number of hops, and transmitted along with the control packets, that are used to reserve the wavelengths. Bursts with larger number of hops have more chances of wavelength reservation than those with smaller number of hops. This results in the decrease of overall burst loss probability and fairness is also improved. Finally the performance of hop based burst-cluster transmission for 14-node NSFNET is evaluated.
