Abstract

A novel restoration scheme, Parted Path Shared Restoration (PPSR), was proposed in this paper. 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, 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.
