Design of Light-Tree Based Logical Topologies for Multicast.. - Yang, Liao (2003) (2 citations) (Correct)
....constraints for the same problera Note that [12 14] do not consider wavelength assignment in the network. Only the routing problem is discussed. Design of logical topologies. Formulation to design the light path based logical topologies for unicast streams are provided in [1 4] Mellia et al. [15] proposes a formulation to design the logical topologies for multicast streams. Both approaches use lightpaths, instead of light trees, to form the logical topologies. Moreover, they assume that either all nodes are capable of wavelength conversion, or no node is capable of wavelength ....
....as discussed in [7 9,12 14] Optimal solution can be obtained using formulation in previous section. Multicasting is only available on logical networks. Each node of a logical network is capable of multicasting. Each edge of a logical network is a lightpath. It is the problem as discussed in [15]. Multicasting is available both on physical networks and logical networks. A light tree can carry data from multiple multicast streams. It is the focus of this section. The set of constraints is listed as follows. 1) Multicast routing constraints: Rn x Z Zn(t j) Rn(j) Vn V, Vj H t:tF,tT ....

.... aspects that must be defined in TS concern: the choice of an initial solution the definition of the topology perturbation that generates the neighborhood the evaluation of the visited solutions the stop criterion As initial solution we select the result of the heuristic, proposed in [13]. This heuristic initially considers a fully connected logical topology, and iteratively removes the least loaded lightpaths from the logical topology, until the degree constraints are satisfied. The perturbation is defined according to the following algorithm: within the current solution, ....
