Deferred Protection of Deadline-Driven Requests in Inter-Datacenter Elastic Optical Networks
, 2020 Inter-Datacenter Elastic Optical Networks (IDC-EONs) can serve increasing traffic demands among distributed datacenters (DC). Inter-DC traffic demands are typically characterized by flexibility in terms of start time, end time, and assigned transmission ...

IET Quantum Communication, Volume 6, Issue 1, January/December 2025.We propose a heuristic adaptive quantum routing (RWTA_AQR) algorithm for routing, wavelength and timeslot assignment. RWTA_AQR utilises the FirstFit algorithm to assign wavelengths in both contiguous and noncontiguous timeslots for optimal resource utilisation based on the priority.

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.
