Abstract:
|
A simple scheme to implement dedicated path protection in Elastic Optical Networks is proposed and evaluated under dynamic traffic conditions. It consists in splitting the spectrum available in the network links in two bands used respectively for working and backup traffic. These bands are conveniently sized taking into account the network topology and the routing constraints. When the band dedicated to backup paths is reduced to achieve a higher throughput in the network, the protection capability is also reduced. Then, some strategies to equalize the protection probability of the different connections sizes are proposed and their performance is evaluated by simulation. |
