Abstract: A network interface apparatus includes a host interface for connection to a host processor and a network interface, which includes multiple distinct physical ports. Processing circuitry associates each of a plurality of virtual entities running on the host processor with a respective one of the physical ports, so that while both of the first and second physical ports are operational, the processing circuitry transmits data packets on behalf of first and second virtual entities, using assigned upper-layer addresses, through associated first and second physical ports. In response to an indication that the first physical port has ceased to operate, the processing circuitry transmits the data packets on behalf of the first virtual entity through the second physical port without changing the upper-layer addresses.

Abstract: A mechanism is provided for partial offload of connection tracking from a host processor to a network interface device. Software running in the host processor is used for connection establishment. After a connection has been established the software initializes and transfers flow-control to the network interface device. Thereafter, the network interface device continues transferring packets to the destination, while the software in the host processor monitors the flow. If the connection has been terminated or has expired flow control reverts to the software. Modes of operation are provided for network interface devices with and without a specific connection-tracking module.
