CCECE 2021 Keynote Speech - Future Optical Network Architechture

#Optical #Network #Architecture

Future optical networks with orders of magnitude increase in data rates and large granularity bursty traffic need an architecture with high efficiency and also adapt dynamically to fluctuating offered loads and rapidly changing networks states. Moreover, applications and computing will impose new requirements on the network infrastructure such as time deadlines. The current network management and control systems only adapt quasi-statically (from minutes to days) due the smoothing effects of significant statistical multiplexing of traffic. Future networks will see increase in demands mostly due to large granularity sessions. These granular sessions present large dynamic range and bursty offered traffic to the network, resulting in unpredictable congestions and blocking. We will explore efficient and agile network algorithms to adapt quickly to changing network conditions: a cognitive network management and control system resides in the network control plane as a collection of coordinated algorithms that sense and infer network states, decide and implement fast scheduling of flows, predict intention of users/applications and take appropriate actions, perform rapid load balancing, and handle resiliency via reconfiguration, restoration and reconstitution of failed network assets.
