SYSTEM AND METHOD FOR MONITORING THE FUNCTIONALITY OF NETWORK INTERFACES
First Claim
1. A method for monitoring functionality of a plurality of network interfaces and providing fault recovery, the network interfaces being grouped into a plurality of nodes and a monitoring address being assigned to each of the network interfaces such that the monitoring address for each of the network interfaces is on a different subnet than the monitoring addresses for all of the other network interfaces in the same node as that network interface, the method comprising the steps of:
- periodically sending a monitoring message to each of the network interfaces via the monitoring addresses in order to determine the functionality of the network interfaces; and
if no monitoring message is received within a predetermined period, performing a recovery operation for one of the network interfaces using one or more recovery addresses of the one network interface, wherein each of the network interfaces is assigned one or more recovery addresses that each are different than its monitoring address.

Abstract
A system, method and computer readable medium are provided for monitoring functionality of multiple network interfaces and providing fault recovery. The network interfaces are grouped into nodes and a monitoring address is assigned to each of the network interfaces such that the monitoring address for each of the network interfaces is on a different subnet than the monitoring addresses for all of the other network interfaces in the same node as that network interface. According to the method, each of the network interfaces is assigned one or more recovery addresses that each are different than its monitoring address. A monitoring message is periodically sent to each of the network interfaces via the monitoring addresses in order to determine the functionality of the network interfaces. If no monitoring message is received within a predetermined period, a recovery operation is performed for one of the network interfaces using one or more recovery addresses of the one network interface.
