Publication number: 20220353005Abstract: The present invention includes novel techniques, apparatus, and systems for optical WDM communications. Tunable lasers are employed to generate respective subcarrier frequencies which represent subchannels of an ITU channel to which client signals can be mapped. In one embodiment, subchannels are polarization interleaved to reduce crosstalk. In another embodiment, polarization multiplexing is used to increase the spectral density. Client circuits can be divided and combined with one another before being mapped, independent of one another, to individual subchannels within and across ITU channels. A crosspoint switch can be used to control the client to subchannel mapping, thereby enabling subchannel protection switching and hitless wavelength switching.Type: ApplicationFiled: June 30, 2022Publication date: November 3, 2022Inventors: Chris Wilhelm Barnard, Piotr Myslinski

Patent number: 10715414Abstract: The present invention includes various novel systems and methods for communication in a network. A System Environment Monitor is employed in some embodiments to extract from the network both real-time and historical Network Metrics at the Infrastructure Layer, as well as Application Metadata at the Application Layer. Network analytics facilitate decisions based upon the differing characteristics of Application Components and lower-level hardware components across multiple DTTs. In response, an SDN Controller generates modified sets of SDN Flows, and implements them in real time across a mixed technology (multi-DTT) network in a manner that avoids disrupting existing SDN Flows and other real-time network traffic.Type: GrantFiled: March 28, 2019Date of Patent: July 14, 2020Assignee: Ribbon Communications Operating Company, Inc.Inventors: Karl May, Alan McKee, Trevor Graham, Richard King, Scott Walker, Piotr Myslinski

Publication number: 20170230133Abstract: This invention relates to provisioning wavelength-selective switches and reconfigurable optical add-drop multiplexers to minimize the bandwidth narrowing effect from the optical filters. Novel architectures and methods are disclosed that can significantly reduce bandwidth-narrowing on channels in a reconfigurable WDM network where a large number of optical filter elements are cascaded. Instead of blocking unused channels as in the prior art, unused channels are selectively provisioned depending on the state of their adjacent channels. Unused adjacent channels of an active channel are provisioned to follow the same path as the active channels. As each channels is deployed, the channel frequency is selected so as to minimize bandwidth narrowing.Type: ApplicationFiled: February 22, 2017Publication date: August 10, 2017Inventors: Chris Wilhelm Barnard, Piotr Myslinski

Publication number: 20140193154Abstract: The present invention includes various novel systems and methods for dynamically modifying WDM transmission and receive steps (individually or in combination), including encoding client signals, mapping them to subchannels within or across ITU channels, modulating them onto subcarrier frequencies, and multiplexing them together for optical transmission. By dynamically modifying one or more of these processing steps over time (as well as encrypting underlying client signals), additional security is provided at the physical (optical) layer of an optical network, thereby greatly enhancing overall network security. Tunable lasers are employed to generate respective subcarrier frequencies, which represent subchannels of an ITU channel to which client signals are mapped.Type: ApplicationFiled: December 30, 2013Publication date: July 10, 2014Inventors: Trevor Graham, Scott Walker, Alan McKee, Karl May, Piotr Myslinski, Richard King
