Flexible ethernet operations, administration, and maintenance systems and methods
A node configured to support a Flexible Ethernet (FlexE) client service in a network includes circuitry configured to receive a FlexE client; and circuitry configured to at least one of monitor and update one or more Operations, Administration, and Maintenance (OAM) fields in FlexE overhead, wherein the OAM fields cover a single client path along many network segments (sections) for the FlexE client. A method, implemented in a node, for supporting a Flexible Ethernet (FlexE) client service in a network includes receiving a FlexE client; and at least one of monitoring and updating one or more Operations, Administration, and Maintenance (OAM) fields in FlexE overhead, wherein the OAM fields cover a single client path along many network segments (sections) for the FlexE client.

2. The node of claim 1 , wherein the circuitry configured to monitor and update is configured to monitor and update a client service error monitoring field in the one or more OAM fields to detect errors over the single client path.
3. The node of claim 2 , wherein the client service error monitoring field is a bitstream Bit Interleaved Parity (BIP) code.
4. The node of claim 1 , wherein the circuitry configured to monitor and update is configured to monitor and update any of a connectivity/trace, link fault, remote fault, maintenance states, test signals, link neighbor discovery, and backwards fault and error indication, in the one or more OAM fields.
5. The node of claim 1 , wherein the circuitry configured to monitor and update is configured to monitor and update the one or more OAM fields separate from standard Local Fault and Remote Fault information for an associated FlexE group/PHY.
6. The node of claim 1 , wherein the one or more OAM fields are located by the circuitry configured to monitor and update using a multiframe scheme in the FlexE overhead.
7. A method, implemented by circuitry in a node, for supporting a Flexible Ethernet (FlexE) client service in a network, the method comprising:
receiving a FlexE client; and
updating and monitoring one or more Operations, Administration, and Maintenance (OAM) fields in FlexE overhead, wherein the OAM fields are monitored and updated over a single client path for the FlexE client,
wherein the one or more OAM fields are implemented in a Reconciliation Sublayer during the updating and monitoring by the circuitry.
8. The method of claim 7 , wherein the updating and monitoring comprises updating and modifying a client service error monitoring field in the one or more OAM fields to detect errors over the single client.
9. The method of claim 8 , wherein the client service error monitoring field is a bitstream Bit Interleaved Parity (BIP) code.
10. The method of claim 7 , wherein the updating and monitoring comprises updating and modifying any of a connectivity/trace, link fault, remote fault, maintenance states, test signals, link neighbor discovery, and backwards fault and error indication, in the one or more OAM fields.
