<p>The present invention provides network interface monitoring and management that may be employed with link aggregation technologies. Multiple network interfaces may be aggregated into a single bond and data may be transferred to and from a backbone network via this aggregated bond. A link aggregation monitor employs a heartbeat generator, sniffer and data store to keep track of health and availability of network interfaces. The heartbeat generator sends heartbeats to the network interfaces, which pass the heartbeats around in a token ring configuration. If a network interface fails or otherwise goes offline, detection of this condition causes the monitor and heartbeat generator to prepare new or modified heartbeats so that data may be efficiently and accurately routed around the token ring and health of all remaining alive interfaces can be monitored properly. If a network interface re-enters or is added to the aggregate bond, new/modified heartbeats are then employed.</p> |
