Abstract
A system which provides for generation of alert packets using network interfaces. The alert packets are downloaded into a network interface, for example during a transition from an OS-present state to an OS-absent state. The alert packets are provided with control fields which, in various combinations, indicate alert conditions upon which such packets are to be transmitted, and which indicate a repetition mode for transmission of the packet after a match of the alert condition. Logic in the network interface, causes scanning in the plurality of packets downloaded into the network interface at scan intervals to identify packets having control codes matching alert signals received by the network interface. The process allows for more than one alert packet to be matched with a single alert signal during a given scan interval, and to be transmitted. Also, in one embodiment, each alert packet which matches an alert signal can be transmitted according to a repetition mode indicated in the control fields of the packet.
