Abstract

We review the most important WDM system innovations motivated by the evolution of DCI transport. State-of-the-art coherent transmission has already exceeded 6 b/s/Hz in transatlantic deployments. Moreover, the adoption of software innovations in automation and programmability, which DCI pioneered in transport networks, has also simplified operations and enables the emergence of open transport architectures. Combining these advances with emerging network analytic frameworks allows exciting innovations in network design and management optimization.

The amount of per-device configuration changes for DC devices (DC routers) is significantly more than that of backbone devices (peering routers, WDM devices). Reference [47] states that 90% of backbone device samples have less than 500 updated lines per week, while only 50% of POP/DC samples are of the same size. Compared to > 700 lines of configuration changes for DC devices, backbone devices see about 150 updated lines per change.
