Publication number: 20210076111Abstract: A mapper includes circuitry configured to receive data streams each or which is a stream of data based on a calendar function associated with one of Flexible Ethernet (FlexE) or Metro Transport Networking (MTN); and circuitry configured to perform mapping of each of the data streams and to provide an output of the mapping to a device in a wireless data plane for transmission over one or more wireless links. The mapping can include packet mapping where the stream of blocks is encapsulated into packets. The mapping can include byte mapping where the stream of blocks is converted into a byte stream that is provided to a Radio Link Control (RLC) layer that guarantees byte delivery in order at a receiver. The mapping can also include bit mapping wherein the stream of blocks is transferred as a stream of bits to a transport buffer Service Access Point (SAP).Type: ApplicationFiled: September 5, 2019Publication date: March 11, 2021Inventors: Stephen Daniel Shew, Sebastien Gareau, Petar Djukic

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
