Abstract
In a typical multicast scenario the tree members (users attached to the tree) change all the time. New users join the tree,while some existing users leave it. Here we consider these dynamically changing multicast trees in two-layer, grooming-capable, optical networks. The continuous changing of the tree members (users) causes the degradation of the tree. Thereforea huge amount of network resources can be spared by periodically repeated reconfiguration. In this paper the benefits ofreconfiguration are investigated for different multi-cast routing algorithms and reconfiguration periods.
