Patent number: 9831977Abstract: Systems and methods for routing wavelengths in an optical network include responsive to a path request for a wavelength or group of wavelengths, determining a path through the optical network; determining a location on the path where wavelength blocking should occur to form a loop-free path in the optical network; and setting the wavelength blocking at the location. The optical network can utilize a broadcast and select architecture and the wavelength blocking is configured to prevent the wavelength or group of wavelengths from looping back on a port where the wavelength or group of wavelengths has already been received on. The optical network can utilize an all-broadcast architecture and the wavelength blocking is configured to prevent multiple paths for the wavelength or group of wavelengths by constraining the wavelength or group of wavelengths to a single path through the optical network.Type: GrantFiled: October 27, 2016Date of Patent: November 28, 2017Assignee: Ciena CorporationInventors: David Weldon Boertjes, Stephen Daniel Shew

Patent number: 9729265Abstract: Systems and methods for providing onsite support to technicians of a network include a hardware means for automatically detecting the presence of an onsite technician at the network node, and providing support to the onsite technician through a communications channel provided by the network node. The communications channel can be an optical service channel or a general communication channel (GCC) configured according to G.709 standard, for example. The hardware means can be further configured to determine an identity of the onsite technician and/or authenticate the onsite technician. The hardware means may comprise a dongle communicatively coupled to a network element or shelf at the network node via a universal serial bus (USB) port or BLUETOOTH connection.Type: GrantFiled: October 24, 2013Date of Patent: August 8, 2017Assignee: Ciena CorporationInventors: Dane Martin Hurley, David Weldon Boertjes, David Casson Bownass
