Probabilistic Preemptive Scheduling for Service Differentiation in OBS Networks
نویسندگان
چکیده
This paper presents a Probabilistic Preemptive (PP) scheduling discipline for service differentiation in Optical Burst Switching (OBS) networks. The main idea of PP is that a probabilistic parameter is added to the preemptive scheduling discipline. With PP, a high priority burst preempts a low priority burst in a probabilistic manner. By changing the probabilistic parameter, PP can achieve flexible blocking differentiation.

A probabilistic preemptive scheme for providing service differentiation in OBS networks
In this paper, we propose a Probabilistic Preemptive (PP) scheme for service differentiation in Optical Burst Switching (OBS) networks. By changing the preemptive probability, an OBS node can adjust the ratio of burst blocking probability between different traffic classes, while the overall blocking probability is not affected.
متن کاملA preemptive scheduling technique for OBS networks with service differentiation
Existing burst scheduling techniques could be improved in terms of bandwidth utilization and QoS support. In this paper, we introduced a new partially preemptive scheduling technique with QoS support. The technique is capable of handling data bursts in parts and may use preemption due to the priorities of data bursts in a multi-service OBS network environment. Simulation studies suggest that mo...

Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...
متن کاملRate-controlled optical burst switching for both congestion avoidance and service differentiation
Optical Burst Switching (OBS) has recently been proposed as a candidate architecture for the next generation optical Internet. Several challenging issues remain to be solved to pave the way for the OBS vision. Contention arises in OBS networks when two or more bursts are destined for the same wavelength, and a wide variety of reactive contention resolution mechanisms have been proposed in the l...
