In the second episode of our series, I explain how multilayer control boosts network resiliency, improves its ability to recover from faults, and at the same time lowers costs. 

Most protection schemes today rely on IP-only restoration in the case of optical failure. It’s a very expensive way of guarding the network, and the required overhead is a main contributor the very low utilization rates that characterize most service provider networks. Switching to multilayer restoration changes that picture. Watch the video to see how.
