  • •Networking Platforms segment revenue decreased, primarily reflecting product line sales decreases of $80.6 million of our Converged Packet Optical products.
  • ◦Converged Packet Optical sales decreased, primarily reflecting a sales decrease of $91.7 million of our 6500 Packet-Optical Platform to communications service providers and Web-scale providers. This sales decrease was partially offset by a sales increase of $9.4 million of our Waveserver® products, primarily to communications service providers and Web-scale providers.
  • ◦Routing and Switching sales remained relatively unchanged.

Forward Error Correction with Compression Coding
29 Jul 21
A method performed at an electronic device comprises receiving information bits, a first nub, and a second nub, each nub comprising redundant values; calculating first calculated determiners from first subsets of the information bits along a first dimension; calculating first corrected determiners by applying first FEC decoding to a combination of the first calculated determiners and the first nub; correcting at least one error in the information bits using a difference between the first corrected determiners and the first calculated determiners; calculating second calculated determiners from second subsets of the information bits along a second dimension that differs from the first dimension; calculating second corrected determiners by applying second FEC decoding to a combination of the second calculated determiners and the second nub; and correcting at least one additional error in the information bits using a difference between the second corrected determiners and the second calculated determiners.

EVPN VPWS FXC local switching connectivity
22 Jul 21
A network element configured to implement an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) Flexible Cross-Connect (FXC) local switching service includes a plurality of ports; and a switching fabric configured to switch traffic between the plurality of ports; wherein a set of ports is configured in a distributed Link Aggregation Group (LAG) with two nodes, and an inter-chassis link configured with a second network element, and wherein, responsive to a failure of the inter-chassis link, a distribution state of members in the distributed LAG is coordinated.
Opportunistic network defragmentation and optimization
20 Jul 21
Systems and methods include determining a defragmentation plan that changes a configuration of a network to move the network from a current state of operation to a new state of operation; updating any of the defragmentation plan and the new state of operation in response to an opportunity presented during operation of the network; and implementing one or more steps in the defragmentation plan based on the opportunity.
Compression forward error correction coding using a tree structure
20 Jul 21
A transmitter generates determiners from data vectors representing payload information, each determiner representing parity information dependent on the payload information.
