Abstract
The Multi-Protocol Lambda Switching (MPλS) has been recently applied in the optical network control plane to provide fast lightpath provisioning. With the growth of traffic in optical network, the survivability of the network becomes extremely important. Therefore, an efficient protection mechanism is needed. Shared backup tree lightpath protection is a promising paradigm in MPλS networks because of its fast recovery from single failure and its efficiency in terms of consumed capacity. In this paradigm, a shared backup tree is used to protect a group of working lightpaths. In this paper, we propose a heuristic that yields an efficient placement of working paths and backup trees in polynomial time.
