In this letter, we study dynamic multicasting in GMPLS networks with unequal branching capability. An overlapped multicasting tree is proposed to reduce blocking probability, which can utilize the branching capabilities more efficiently than the traditional Steiner tree. A nearest node branch first heuristic is developed to find such an overlapped tree.

The network performance of a single joint multicasting capable optical cross-connect (jMC-OXC) integrating both space- and frequency-splitters is simulated. The results show that the jMC-OXC architecture with limited frequency-splitters can obtain a close performance to that with full frequency splitters. The improvement offered by jMC-OXCs on the performance of multicasting routing is also discussed.
