Abstract

Optical Burst Switching (OBS) is a promising candidate for a more dynamic optical network layer. Wavelength resources must be reserved in core nodes for each passing burst. This reservation task is done by reservation modules in the output ports of OBS nodes. As processing of control information should not limit the performance of the system, the reservation process must be performed in short time intervals. This paper surveys reservation schemes in OBS and discusses relevant scenarios with respect to offset values. Then, architectures for reservation modules supporting the just-enough-time (JET) reservation scheme are presented. Finally, their implementation complexity and their scalability are analyzed.
