First Claim
Patent Images
1. A method for failover when at least one of a network adapter and a data path through the network adapter fails, wherein the network adapter is connected to a miniport driver that is connected to a filter driver, comprising:
- determining, with the miniport driver, that the network adapter has failed;
using a callback interface to notify, with the miniport driver, the filter driver that the network adapter has failed; and
completing, with the miniport driver, processing of pending packets directed to the network adapter that has failed with a success status.

Abstract
Also provided are techniques for failover when a network adapter fails, wherein the network adapter is connected to a miniport driver that is connected to a filter driver. With the miniport driver, it is determined that at least one of the network adapter and a data path through the network adapter has failed. With the miniport driver, the filter driver is notified that at least one of the network adapter and the data path through the network adapter has failed.
