AIMD control for deflection routing in OBS networks

A novel scheme entitled as Additive Increase Multiplicative Decrease control with the Number of Burst Control Packet (AIMD-NBCP) is proposed. The basic idea of AIMD-NBCP is to count the number of the burst control packet (BCP) at the core node and estimate the average load by which to adjust the burst transmitting rate of the edge node with the AIMD scheme. Simulation results show that AIMD-NBCP scheme is efficient at keeping the network stable and enhancing the performance of deflection routing in terms of good-put, burst loss probability as well as fairness index.
