Abstract
A method of operating a network computer system provides redundant Internet Protocol (IP) Multicast traffic flow on a group of physical ports and comprises virtualizing the group of physical ports into a single virtual Network Interface Controller (NIC), validating network connectivity in a logical group comprising at least one of the physical ports in the virtualized group, and responding to failure of a physical port that is actively receiving on an IP Multicast traffic flow by instigating failover of the actively received IP Multicast traffic flow to a physical port in the logical group with validated network connectivity.
