Optimal path calculation method of optical network under complex constraints

Engineering Reports, Volume 6, Issue 12, December 2024.
In view of the complex logical constraints in SDON services, a unified constraint expression is proposed, and the network topology is layered to transform, creatively solving the urgently needed “and,” “or,” bidirectional link and other logical types in SDON services, constrained path calculation problem.

Survivable multipath routing of anycast and unicast traffic in elastic optical networks

, 2016
In this paper, we focus on the survivability of elastic optical networks (EONs) that jointly support two types of traffic demands: unicast and anycast. To provide network survivability, we apply multipath routing; i.e., we allow the splitting of a demand
