Using dual-path allocation for partial traffic protection in elastic optical networks

Multi-path allocation has been proposed as a simple way to achieve traffic protection in different networking domains. In this work dual-path allocation is proposed for Elastic Optical Networks (EON) assuming dynamic offered traffic, and its performance is quantified by simulation. Indeed, dual-path allocation is compared with partial dedicated path protection assuming different scenarios. In addition to a qualitative comparison where advantages and drawbacks of both schemes are analysed, quantitative results for different backbone network scenarios are presented.Peer Reviewe
