Burst Queue Schemes in Optical Burst Switching Network Edge Node

Optical burst switching technique has gained considerable interest for the reason that it merges the merits of optical packet switching technique and optical circuit technique. But as far as we know, there is no research about the burst queue schemes in an optical burst switching edge node. The functional architecture of optical burst switching network edge node is briefly introduced in this paper, and the function of each part is analyzed in brief. We then present three burst queue schemes:centralized queue scheme, mixed queue scheme and individual queue scheme. Theoretical analysis and simulation results demonstrate that the centralized queue scheme is the best.
