Dynamic Resource Allocation for All-Optical Multicast based on Sub-tree Scheme in Elastic Optical Networks

Not Accessible

Abstract

All-optical multicasting with a single light-tree suffers inefficient distance-adaptive spectrum allocation from its large tree-spanning size. We propose a routing modulation format and spectrum allocation (RMSA) algorithm based on sub-tree scheme to improve spectrum utilization.
