Abstract

A differentiated survivable service provisioning (DSSP) framework is investigated in this paper for optical networks providing dedicated path protection (DPP) and shared path protection (SPP) services. To tackle the service provisioning problem under the framework, spare capacity allocation (SCA) problem is studied first. The structure of the problem is captured by a set of matrices. Then, based on the matrix model, a path-flow integer linear programming (ILP) formulation is presented to find the optimal service provisioning solution for a given set of traffic demands. The objective is to minimize total capacities consumed by working and backup paths of all demands. Furthermore, network performance under the dynamic DSSP framework is illustrated in terms of blocking probability, resource overbuild and average hop distance.
