Systems and methods utilize an all-or-none switchover to prevent split-brain problems in a Multi-Chassis Link Aggregation Group (MC-LAG) network. A standby node in the MC-LAG network can perform the steps of remaining in a standby state responsive to a loss of adjacency with an active node, wherein, in the standby state, all standby links between the standby node and a common endpoint are non-distributing; monitoring frames transmitted by the common endpoint to the standby node over the standby links; and determining based on the monitoring frames whether all active links between the active node and the common endpoint have failed and entering an active state with all the standby links distributing based thereon.

Systems and methods for L2 Ethernet resilient hand-off include an access network configured between a first end point and a second end point, a first communication path and a second communication path for data flow between the first end point and the second end point, wherein the first communication path is active and the second communication path is inactive, and if a fault is detected in the first communication path, logic configured to activate the second communication path and perform a resilient hand-off of the data flow from the first communication path to the second communication path.

Resilient dual-homed data network hand-off

The disclosure is directed to configuring an internetworking of a first network and a second network. Data representing one or more network events is received at a network element, data representing one or more actions to be performed by the second network in response to detection of the one or more events on the first network is received at the network element, and a mapping of the one or more network events to the one or more actions is stored by the network element.

Systems and methods for LEthernet resilient hand-off include an access network configured between a first end point and a second end point, a first communication path and a second communication path for data flow between the first end point and the second end point, wherein the first communication path is active and the second communication path is inactive, and if a fault is detected in the first communication path, logic configured to activate the second communication path and perform a resilient hand-off of the data flow from the first communication path to the second communication path.

One embodiment of the present invention provides a switch. The switch includes an ownership management mechanism and a notification mechanism. The ownership management mechanism maintains a local ownership association between the switch, and a medium access control (MAC) address learned at the switch and terminates the local ownership association for the MAC address. The notification mechanism generates a first notification indicating the local ownership association and a second notification indicating the termination of the local ownership association.
