Optical burst switching (OBS) control architecture considers two different models for the management of the offset time in the network. The conventional OBS (C-OBS) introduces the offset time in soft-way by delaying the transmission of the burst relative to its control packet in the edge node. Another idea for an OBS architecture (E-OBS) comes from optical packet switching world and it intends to...
Burst preemption is the most effective technique to provide quality of service (QoS) differentiation in optical burst switching (OBS) networks. Nonetheless, in conventional OBS architectures, when preemption happens the control packet corresponding to the preempted burst continues its travel to the destination node reserving resources at each node of the path. Therefore, an additional signaling procedure...
