Publication number: 20230327758Abstract: An optical communications network comprises optical data links comprising data channels. A time-domain sampled waveform of a selected data channel is obtained. The Fourier transform is applied to the time-domain sampled waveform of the selected data channel to generate a frequency-domain waveform of the selected data channel. Time-domain sampled waveforms of the selected data channels neighboring data channels are obtained. The Fourier transform is applied to the time-domain sampled waveforms of the neighboring data channels to generate frequency-domain waveforms of the neighboring data channels. The noise-to-signal ratio is calculated based on the frequency-domain waveforms. Based on the calculated noise-to-signal ratio, an optical signal to noise ratio (OSNR) penalty is estimated. A notification is generated when the OSNR penalty exceeds a predetermined threshold.Type: ApplicationFiled: June 14, 2021Publication date: October 12, 2023Inventors: Yawei YIN, Binbin GUAN

Publication number: 20230275666Abstract: Systems and methods are provided for determining an optical bypass for an inter-regional wide area network (WAN) for regions of server facilities of a cloud service provider. In particular, the optical bypass connects non-adjacent regional server centers of the WAN by eliminating needs of data conversions at intermediate regional server centers. The determining the optical bypass includes receiving a WAN topology data, capacity and demand information about the WAN. The determining includes an objective function to maximize a number of network resources to free up by determining a revised data flow and bandwidth allocations by introducing the optical bypass in the WAN.

Publication number: 20230198653Abstract: An optical communications network comprises optical data links interconnected by add-drop nodes, the optical data links comprising data channels. The data channels are allocated into equal-sized bins. In response to a first data channel request between a given source-destination pair, one of the equal-sized bins is assigned to the data channel request. In response to requests for additional bandwidth for the same source-destination data channel request, unused channels within the assigned equal-sized bin are allocated to the data channel request. In response to subsequent data channel requests between different source-destination pairs, additional unallocated equal-sized bins are assigned to the subsequent data channel requests. In response to subsequent data channel requests when resource sharing for one equal-sized bin, data channels in the last equal-sized bin are assigned using the reverse channel assignment process. Reverse channel assignment can also be used for other bins as an option.Type: ApplicationFiled: February 21, 2023Publication date: June 22, 2023Inventors: Yawei YIN, Karthikeyan BALASUBRAMANIAN
