MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202411078573 A) filed by Ciena Corporation on October 16, 2024, for Sparse Route Computation For Determining Optical Paths With Defined Optical Regenerator Locations.
Inventors include Seemant Bisht; Anikash Chaudhary; Dominic Richens; and Mohit Chhillar.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: Systems and methods for a sparse route computation for determining optical paths with defined optical regenerator locations in an optical network include receiving (302) a request to compute one or more paths from a source node (12A) to a destination node (12J) with one or more regen nodes (12R) in an optical network (10); utilizing (304) the one or more regen nodes (12R) as an inclusion hops list and performing a Shortest Path First (SPF) computation with the inclusion hops list to find the one or more paths with tentative (tent) paths maintained in a tent list and further utilizing a discourage factor in minimal route diversity to order the tent paths in the tent list based on the inclusion hops list.
