Abstract
Methods and apparatus for processing a network connection in a computer system including a software network protocol stack and a network interface card including a hardware network protocol stack are disclosed. State information associated with the network connection is provided to or received by the driver associated with the network interface card. The driver provides the state information to the network interface card, thereby enabling the network interface card to process the network connection. In addition, any packet that is processed by the network interface card is also provided to the driver. Since the driver can maintain a copy of the state information and a copy of the data packet, the software network protocol stack can obtain the state information and the data packet from the driver in the event of a failure of the network interface card.
