  • Pausing a media access control security (MACsec) key agreement (MKA) protocol of an MKA session using a fast heartbeat session
    Patent number: 11895228
    Abstract: A network device may establish a media access control security (MACsec) key agreement (MKA) session with another network device via a MACsec communication link; establish a fast heartbeat session via the MACsec communication link, between a first packet processing engine of the network device and a second packet processing engine of the other network device, where the fast heartbeat session is to permit the first packet processing engine and the second packet processing engine to exchange fast heartbeat messages via the fast heartbeat session and the MACsec communication link; place an MKA protocol of the MKA session in a pause state until the first packet processing engine detects a rekey event; determine that a key for the MKA session is to be regenerated based on detection of the rekey event; and perform an action based on the rekey event for the MKA session.

  • Fast heartbeat liveness between packet processing engines using media access control security (MACsec) communication
    Patent number: 11316858
    Abstract: A device may include one or more processors to establish a media access control security (MACsec) key agreement (MKA) session between a first network device and a second network device via a MACsec link; establish a fast heartbeat session via the MACsec communication link, between a first packet processing engine of the first network device and a second packet processing engine of the second network device, to permit the first packet processing engine and the second packet processing engine to exchange fast heartbeat messages via the fast heartbeat session and the MACsec communication link; determine, based on the fast heartbeat session, that the MKA session has ended; and/or perform an action based on the MKA session ending.
