Experimental Demonstration and Benefits of Self-Healing Hard-Wired and Synthetic ROADMs

Dynamic provisioning utilizing redundant modules in elastic optical networks based on architecture on demand nodes

“…Simulations are carried out on the NSF topology 6 , with 14 nodes and 42 unidirectional fiber links, each supporting 80 spectrum slices. It is assumed that only single SSS failure can occur in the network, i.e., the probability that two or more SSSs will fail at the same time is considered to be negligible.…”

“…The presented results are averaged over fifty experiments for each traffic load value. The number of active SSSs initially placed at each node is determined by the offline design procedure described in 6 , where the network is dimensioned differently for each specific traffic condition. This translates in an overall number of switching modules in the network that is relatively small for low loads, and increases for higher load values.…”

OSNR-aware Control of Optical White Boxes on Elastic Optical Networks

“…Steps (4) to (6) can be adapted to optimize scalability [3] or power balance [7]. Finally, (7) accounts for self-healing properties [4], number of WSSs employed [5] and total network power consumption [6].…”

“…EONs require advanced optical node architectures. Recent proposals on Architecture on Demand (AoD)-based function programmable optical networks offer scalability [3] reliability [4], CAPEX [5] and power consumption (OPEX) [6] savings compared with traditional optical node architectures. However, to the best of the authors' knowledge, no studies jointly exploit the AoD benefits in EON scenarios to increase network capacity or improve spectral efficiency.…”
