Abstract
An incremental capacity allocation with topology augmentation problem is investigated in this article to maximize the service restorability in SDH/SONET mesh networks. To tackle the optimal design problem, two schemes are proposed, i.e., minimal backup path provisioning with topology augmentation (MBPP-TA), and global path pair provisioning with topology augmentation (GPPP-TA). Both schemes are formulated as integer linear programming (ILP) models, and are implemented using the proposed two-step linear programming (LP) approaches. Numerical results show that the two-step LP approaches achieve better solutions with significantly less execution time than the direct ILP approach. Moreover, results show that GPPP-TA provides better solutions than MBPP-TA at the cost of longer computation time.
