A novel restoration scheme, Parted Path Shared Restoration (PPSR), was proposed. The major idea of PPSR is the strategy of ‘parted disposal’. PPSR keeps the advantage of Path Based Shared Restoration (PBSR) in utilization of capacity. In addition, the restoration time of PPSR is much less than that of PBSR. Furthermore, a satisfaction function was proposed to estimate the performance of PPSR. This function takes the utilization of capacity and restoration time into a harmonious and uniform frame. Through theoretical analysis and computer simulation, the performance of PPSR was demonstrated.

This paper addresses the problem of optimally placing a limited number of wavelength converting nodes in multicast optical wdm *** problem is motivated by the high cost incurred in the usage of *** propose a Mixed Integer Linear Programming（MILP） formulation algorithm with the objective function of minimizing the total costs for a given set of multicast sessions in wdm *** results show that the algorithm is tractable in networks with dozens of nodes.
