Multicast applications have attracted more and more attention due to more efficient bandwidth usage and the increasing popularity of the point-multipoint multimedia applications. Optical multicasting outperforms the electronic multicasting in some aspects. Service level agreement (SLA) and quality of service (QoS) are important to service providers and users. Service providers always first maximize revenue to accept as many as connection requests as possible and then to minimize the capacity of all accepted connection. In this paper, the problem of cost-effective optical multicasting connection provisioning to satisfy the connections' availability requirements on a given physical topology is formally stated. We propose a mixed integer linear program (MILP) based approach for static multicast traffic. The feature of our algorithm lies on without considering any protection schemes, and when the system adapts dedicated protection or the sharing protection, the problem is more complicated.
