Abstract
This paper addresses dynamic restoration to the scenario of single link failure for survivable traffic grooming in WDM mesh networks. Two restoration schemes are proposed, dynamic restoration at connection granularity (DRAC) and dynamic restoration at lightpath granularity (DRAL). DRAC routes a failed connection to a new multihop path, while DRAL routes a failed lightpath to a new lightpath or other available lightpath. Then we compare the two restoration schemes with other schemes for survivable traffic grooming.
