Utilization balancing algorithms for dynamic multicast scheduling problem in EON
Abstract
Dynamic data transfer demands are often being a challenge for present communication networks, as they appear in unpredictable time and must be satisfied prior to deadline. Important kind are the multi-target demands occurring in task of replication, backup, database synchronization or file transferring in pear-to-pear networks. Optimal scheduling usually depends of the nature of transport network. In the paper we consider dynamic deadline-driven multicast scheduling problem over elastic optical network. We propose the method for improving link utilization by traffic balance for multicast demands. We present few heuristic algorithms and results of experiments, proving the benefits of balancing concept.References
