Abstract
A client on a network is provided with low power logic, at the network adaptor, that is always active and simulates network packet traffic (e.g. Ethernet packets) normally sent under control of the main client system processor(s). This logic collects client status information regarding power state and reports to the network manager such information which allows the network manager to exercise broader control and perform maintenance and upgrades which would usually require a dialog with the user and consequently limit off-hours reconfiguring of the client.
Claims8
A client computer system coupled to a server computer system via a personal computer network, said client computer system including a network adaptor with a transfer portion connected to the network that conditions signal packets in a predefined digital format received from a client side portion thereof to a form to be transmitted over such a network and has a plurality of power states including a fully operational state, an off state and at least one partially powered state in which the client computer system is not fully operational, said client computer system comprising:
- auxiliary logic which monitors client computer system events in all of said plurality of power states to identify a current one of said plurality of power states of the client computer system, said auxiliary logic monitoring system events which occur within said client system;
- transfer logic, cooperating with said auxiliary logic, connected to said transfer portion at the client side thereof, which stores the identity of the current power state, creates packets specifying said current power state according to the predefined digital format and applies them to said transfer portion for transmission at predetermined intervals irrespective of said current power state of said client computer system;
- and
- a power source which applies continuing power to said auxiliary logic and transfer logic irrespective of the power state of said client computer system.
