Priority-Aware Optical Shared Protection Coupled With Mutation Probability
Source: Concordia University
The next big challenge for optical network operators is to meet the diverse availability requirements of the various subscribed services through the adoption of appropriate protection strategies. One promising scheme that has been proposed in the open literature and that is presenting itself as a potential approach to dealing with this challenge is the priority-aware protection scheme. However, the priority-aware protection strategy suffers from a major limitation as it privileges the failed high priority connections taking no account of the failed low priority ones. As such, this paper proposes to combine priority-aware shared protection with a parameter called mutation probability thus giving birth to a more effective protection strategy.
