Abstract
Light-trail is a solution to providing high resource utilization and sub-wavelength support [1]. A light-trail is a multi-point light-path, such that multiple users can take part in communication along the trail, through time (differentiated) non-overlapping connections. This multi-point flow model leads to a new set of problems in the area of protecting and restoring light-trail based networks. Conventional link protection which just protects the existed connection in the light-trail at the time of the failure is not sufficient for light-trails because of the potential of having multiple possible source-destination pairs in the same trail over time. The fact is demonstrated and explained detailedly in [4]. In this paper, a novel protection mechanism is proposed for light-trail WDM mesh network, which is Backup Light-trail Expending scheme. Subsequently the performance of this scheme is evaluated and compared to conventional Connection Dedicated Protection Scheme. Numerical results obtained by simulation indicate that, Backup Light-trail Expending Scheme has a faster restoration time and better wavelength utilization.
