Abstract: Networks devices interconnected via link groups may implement micro operations administration and maintenance (micro-OAM) sessions. The micro-OAM sessions may be used to monitor the status of individual links within the link groups at small time scales. The micro-OAM session may be implemented on a non-internet protocol (non-IP) layer. In some cases, independent micro-OAM sessions may be used to monitor different links within a link group.

Abstract: Disclosed are various embodiments for providing a data packet with timestamp information. A data packet is generated such that it comprises a payload and a header. The payload comprises a first timestamp field that comprises data indicating when a network device processed the data packet. The payload also comprises a body data field and a body data protocol field. The body data protocol field comprises data identifying a protocol used by body data in the body data field. The header comprises a payload protocol field that comprises data identifying that the payload comprises timestamp data.

Abstract: Disclosed are various embodiments providing offload processing circuitry of a network switch. The offload processing circuitry receives an administrative packet from a network switch, the offload processing circuitry being communicatively coupled to a network switch via an Ethernet interface. The offload processing circuitry identifies a receive offload header associated with the administrative packet, the receive offload header comprising a media access control (MAC) address associated with the offload processing circuitry. The offload processing circuitry updates a state machine based at least upon the administrative packet. The offload processing circuitry transmits packets to a network switch by encapsulating it in offload header. The network switch uses the offload header to forward the packet to a proper port.
