Abstract

Based on current load balance and minimum interference routing technology, a least interference optimization based dynamic multi-path routing algorithm (LI-DMA) in automatically switched optical network (ASON) is proposed. LI-DMA employs least interference technology and takes future demands into consideration while calculating routing paths. In LI-DMA, the link cost is dynamically adjusted according to its residual capacity and criticality, and the traffic is distributed to several disjoint paths equally while loading the connections. Simulation results show that, compared with conventional routing algorithms, LI-DMA can efficiently decrease the blocking probability of network and achieve better performance of load balance.
