Abstract :
To support large-scale IP-TV signal delivering, a new multicast-IP over light-tree network model was proposed in W. Sun et al. In this paper, we study the problem of topology-independent IP group aggregation in the multicast capable optical network. We first use a tri-partite graph to describe the problem, and then formulate the problem by a mixed integer linear programming (MILP) model. Finally, we propose a pre-estimation for the number of light-trees to reduce the searching space, which significantly saves solving time of MILP
