Data explosion and higher service level agreements (SLA) are common terminologies in modern communication networks. Recent advancements toward 5G networks add to the complexity where billions of devices, both static and mobile, are connected generating trillions of megabits of data flooding the network and where service providers scuffle daily to deliver key performance indicators: Lower latency, longer battery life, higher data rates, ultra-high reliability, and more connected devices. The optical-fiber world simultaneously witnesses a denser, fiber-rich network infrastructure which is critically challenged in fast economically developing countries by heavy construction of roads and other infrastructures that inflict repeated and unpredictable cuts to the extent that traffic is simultaneously interrupted in up to 10% of the optical links. Thus, network resiliency to fiber failures is already and will continue to be a top …
