  • Publication number: 20250227397
    Abstract: Systems and methods implemented by a network element in a G.8032 ring include steps of (52) operating an Operations, Administration, and Maintenance (OAM) session with an adjacent network element; and detecting (54) an optical bypass in the G.8032 ring based on the OAM session. The steps can include flushing (56) a forwarding database of the network element based on the optical bypass. The steps can include detecting (58) prior to the optical bypass, that a neighboring node includes a ring block; and subsequent (60) to the optical bypass, installing a new channel block. The optical bypass enables faster protection switching and the present disclosure incorporates an optical bypass in G.8032.

  • Publication number: 20190132261
    Abstract: Systems and methods of Ethernet link locking to detect incorrect cabling implemented at a network element include identifying information using Link Layer Discovery Protocol (LLDP) on a port in the network element communicatively coupled to an adjacent port on an adjacent network element; configuring a maintenance association and port Maintenance End Point (MEP) on the port with the adjacent port on the adjacent network element and using the identified information; exchanging Continuity Check Messages (CCM) over the maintenance association; and detecting a port mismatch between the port and the adjacent port based on CCM-based faults.
