Abstract:
1. A method for configuring a network interface, comprising: receiving a signal that was sent from an operating system indicating that the network interface can be idled, wherein the signal is sent from the operating system as soon as the operating system determines that a final route structure that depended on the network interface has expired and been deleted; and determining if an application has established, after the signal was sent from the operating system, a route that uses the network interface, wherein determining if an application has established a route includes one of querying the operating system or an application to determine if another application has established a route or searching any route structures in the operating system to find a matching route, if an application has not established, after the signal was sent from the operating system, a route that uses the network interface, causing the network interface to be idled; otherwise, if an application has established, after the signal was sent from the operating system, a route that uses the network interface, leaving the network interface in a current operating state.
