VP-BASED ATM NETWORK DESIGN WITH CONTROLLED OVER-SUBSCRIPTION OF RESTORATION CAPACITY

--We develop an optimization method which allows exploitation of the statistical nature of ATM traffic to reduce the total spare capacity required for restoration, with a controlled maximum impact on QoS. Results show that significant capacity savings can be obtained if ATM VP restoration is allowed even modest restoration-induced over-subscription of bandwidth on surviving spans. We give Integer Program (IP) formulations and a pair of algorithms for upper and lower bounding of the spare capacity required for ATM Backup-VP restoration. While significant capacity savings are found, they are not as large as in some prior work which appears to have involved uncontrolled over-subscription effects as a side-effect of the capacity planning algorithm used.
