As a promising switching paradigm

Optical Burst Switch (OBS) was proposed for optical networks showing higher efficiency and shorter delay than traditional circuit switching

and it is more feasible than optical packet switching.In OBS

burst assembly is one of the critical technologies

and will significantly affect the performance of networks.In this paper

we focus on the study of burst assembly mechanism

and propose a new burst assembly algorithm

which reduces the self-similarity of IP traffic

enhances the data burst utilization and avoids the bandwidth contention due to sending burst data synchronously at different ingress nodes.
