Abstract
One embodiment of the present invention sets forth a method for failing back network connections to a network interface card (NIC) within a computing device. The method includes the steps of monitoring a failed or unreliable NIC within the computing device, determining that the failed or unreliable NIC has recovered, determining that a functional NIC within the computing device is overloaded, selecting a first connection set communicating through the overloaded NIC, and transferring the first connection set to the recovered NIC. With this approach, intelligent decisions can be advantageously made regarding whether to fail back a network connection set to a recovered NIC based on the traffic loads on the overloaded NIC and the recovered NIC. Such an approach to balancing network traffic across the functional NICs within a computing device may substantially improve overall performance relative to prior art techniques.
