Patent number: 10015057Abstract: Systems and methods for a representative bandwidth calculation in a network include receiving a request for representative bandwidth information; obtaining network measurements; combining, filtering, and retiming network measurements based on the request to determine the representative bandwidth information. The systems and methods convert the combined, filtered, and retimed network measurements into the representative bandwidth information which has an additive property in an algebraic domain. The additive property enables the representative bandwidth information to be used for admission control, overbooking determinations, network planning, and/or dynamic pricing in the network.Type: GrantFiled: January 26, 2015Date of Patent: July 3, 2018Assignee: Ciena CorporationInventors: Petar Djukic, Todd Morris, Romualdas Armolavicius
