A survey of Reservation schemes for Optical Burst Switching (OBS)

Optical Burst Switching (OBS) is an efficient switching method to building very high capacity routing switches based on all optical burst data and electronic processing for the control data. OBS combines the benefits of circuit switching and packet switching while taking into consideration the limitations of the current all-optical networks. In this paper we introduce the concept of OBS network and examine the various OBS reservation schemes. A comparison amongst the different reservation schemes is made in terms of admission, delay, delivery, and QoS. Key-Words: Optical Burst Switching (OBS), Quality of Service (QoS)
