The demonstration was conducted on a live network setup, encompassing equipment from five different vendors in both the IP/MPLS and Optical layers. After a fiber failure was simulated, the app started operating automatically and restored traffic. The process took into consideration both network layers and achieved optimal restoration order with minimum loss of traffic. After the fiber cut was fixed, the app also reverted to normal operations without any loss of traffic.
Multilayer restoration can transform carrier business. Currently, core and metro networks are heavily underutilized since their electrical protection schemes require massive overprovisioning. Orchestrating IP and optical resources, multilayer restoration allows carriers to run their network at much higher utilization rates without compromising resilience. This could save up to 50% of the $26B spent each year on network expansions.
