Abstract
We investigate the problem of grooming dynamic multicast traffic in WDM mesh networks. This problem is equivalent to designing a light-tree based logical topology for multicast streams. It consists of four sub-problems, namely routing, wavelength assignment, design of a light-tree based logical topology, and traffic-grooming. We develop different routing schemes to efficiently groom low-speed connections on the light-tree based logical topology. Numerical results demonstrate that the proposed approaches use the network resources more efficiently compared to the non-grooming approach and the approach of serving the multicast requests as separate unicast requests. Moreover, amongst the proposed techniques, the Logical-First multi-hop grooming scheme MC-MH1 outperforms all other schemes in terms of blocking probability and performance gain.
