“…Many of fair bandwidth allocation schemes, e.g., schemes proposed in [6]- [9], including the case of using the adaptive max-min rate allocation for RFP, use control plane to update arrival and fairly allocated rates of flows among switches. This information can be used for predicting the status of the network.…”

Preemption is one of the most effective ways to achieve fair bandwidth allocation in ORS networks. Preemption allows ingress edge switches to transmit the traffic of flows over their fairly allocated bandwidth but core switches drop over-used traffic when there is contention. This paper proposes a rate-fairness preemption combined with deflection routing (RFP-DR) scheme to provide service isolation and protection among flows according to the max-min fair bandwidth allocation and minimize total loss probability in ORS networks. Our deflection routing (DR) technique aims to decrease loss probability while preserving the definition of max-min fairness. In addition, our DR can also be applied to rate control approaches. Our simulation results prove that our proposed combination of RFP and DR works well in terms of preserving max-min fair-share and minimizing loss.

“…The RFP-DR-based core switches use the effective link capacity, exC (O'<esl), to allocate the max-min rate instead of the actual link capacity C due to the high loss and incomplete link-utilization characteristics of OBS networks. This modification is the same as that done in [6], [7], and [9]. A properly set value for e can be found in [7].…”
