Abstract: Method and apparatus for assigning policies which are rules that govern the use of or access to network services. Each rule defines conditions that when evaluated true trigger actions to allow or deny the service. Techniques are disclosed which provide for explicit, flexible, and centralized assignment of policy to targets which are specified network services. These techniques include explicitly associating a policy with a network resource or process, grouping policy related processes, grouping related targets, associating groups of targets with groups of policies, mapping a user name contained in a policy to an associated network address such as an Internet Protocol (IP) address, and providing dynamically mapped policy identified user and host names with associated network addresses, such as IP addresses, to client processes.

Abstract: A client computer system is suitable for connection to a data processing network having a controlling system. The controlling system is operable to issue a wake-up request to the client computer system. The wake-up request is issued by means of a wireless connection between the controlling system and the client computer system. The client computer system, on receipt of the wake-up request, powers itself on so as to allow normal operation of the client computer system.

Abstract: A call is set up between a subscriber premises and a call center. The subscriber premises includes a personal computer and a telephone. A call set up request is received from a gateway responsive to the personal computer of the subscriber premises. A query is sent to the call center. An availability reply is received from the call center, and a call set up instruction is prepared for setting up the call between the telephone of the subscriber premises and the call center. In some cases, an unavailability reply is received from the call center. The time-in-queue until the call center will be available to receive the call is estimated, and a call queue status message is prepared for delivery to the gateway and thence to the subscriber premises.
