OPERATING A NETWORK NODE CONFIGURED AS PART OF A LINK AGGREGATION SYSTEM

摘要

A system and method of operating a network node configured as part of a link aggregation system. The system includes a plurality of first network nodes and a plurality of second network nodes for providing connectivity to first and second networks respectively, and a plurality of links between the first network nodes and the second network nodes. The network node is configured as one of the first network nodes.;The network node may be set in one of an active operation mode and a standby operation mode based at least in part on a comparison of a priority with one or more received priorities. The priority may be based on connectivity to an active second network node or links available for selection. The network node may determine that it is isolated from the first network and indicate that isolation in control messages sent to second network nodes.

1. A method of operating a network node configured as part of a link aggregation system, the link aggregation system comprising a plurality of first network nodes for providing connectivity to a first network, a plurality of second network nodes for providing connectivity to a second network, and a plurality of links between the first network nodes and the second network nodes, wherein the network node is configured as one of the first network nodes and the method comprises:
sending link aggregation control messages to other network nodes in the link aggregation system; receiving link aggregation control messages from the other network nodes in the link aggregation system; determining an active second network node from the received link aggregation control messages; determining a priority based at least in part on connectivity of the network node to the active second network node; and setting the network node in one of an active operation mode and a standby operation mode for the link aggregation system based at least in part on a comparison of the priority with one or more received priorities from the received link aggregation control messages, the one or more received priorities based at least in part on connectivity of others of the first network nodes to the active second network node.
