Abstract

In this paper we study dynamically changing multicast trees (light-trees) in double-layer optical networks. In this scenario, the continuous changing of multicast endpoints causes the degradation of the tree. Therefore a huge amount of network resources can be spared by regular reconfiguration. The benefit of reconfiguration is investigated for different routing algorithms and reconfiguration periods.
