Cognitive all-optical fiber network architecture

Abstract

The optical network of the future will have ~3 orders of magnitude increase in data rates, mostly due to large transactions. These elephant flows need fast scheduling of network resources and agile network adaptations for congestion control, load balancing and reconfiguration to cope with huge traffic transients and reconstitution for network resilience. This paper move beyond SDN as well as “orchestration,” to involve all layers particularly the optical Physical and Control layers for fast (~100ms) and efficient adaptation using cognitive techniques.
