摘要： A Machine Authentication PAC (Protected Access Credential) serves as machine credentials to obtain network access without requiring server storage and management of the additional set of credentials. The first time authentication is performed, user authentication is executed. After the supplicant and server have mutually authenticated each other and satisfied other validations, the supplicant requests a Machine Authentication PAC from the server. The Server randomly generates a cryptographic key (Device Key) and sends it to the supplicant along with an encrypted ticket, comprising the Device Key and other information and encrypted with a key only known to the Server. The supplicant caches the Machine Authentication PAC in its non-volatile memory for future use. When the machine needs to access certain network services before a user is available, the supplicant uses the Machine Authentication PAC to gain authorization for the machine to limited access on the network, without requiring user input.

摘要： A method and system for performing pre-authentication across inter-subnets. A pre-authentication request is received by a first access point associated with a first subnet from a mobile node requesting that is requesting pre-authentication with a second access point associated with a second subnet. The request is forwarded by the access point to a first authenticator that is the authenticator for the first subnet. The first authenticator obtains from a root infrastructure node the address for a second authenticator that is the authenticator for the second access point. The first authenticator then pre-authenticates the mobile node with the second authenticator by sending a message to the address for the second authenticator.

摘要： In a computer system including a processor coupled to a memory via a bus, a system for a reduced instruction set graphics processing subsystem. The graphics processing subsystem is configured to accept graphics data from a computer system via a bus. The graphics processing subsystem is deeply pipelined to achieve high bandwidth, and is operable for processing graphics data including a first and second set of graphics instructions. The graphics instructions from the second set are more complex than the graphics instructions from the first set. The graphics processing subsystem also includes a built-in recirculation path for enabling the execution of graphics instructions by multi-pass. The graphics pipeline is streamlined such that the graphics instructions from the first set are processed efficiently. The graphics instructions from the second set are processed by using multi-pass via the recirculation path. By being optimized for the first set of graphics instructions, the graphics pipeline is able to run at very high clock speeds, thereby increasing its aggregate bandwidth.

摘要： A method for multicast load balancing in a wireless network having a plurality of access points. The method includes setting a maximum Internet protocol multicast bandwidth for the access points, receiving an admissions control request from a client at one of the access points, and determining whether the admissions control request from the client is for an admitted or unadmitted multicast stream at the access point. The access point is responsive to the admissions control request for the admitted multicast stream by servicing the admitted multicast stream and to the admissions control request for the unadmitted multicast stream by servicing the unadmitted multicast stream where the bandwidth required for the unadmitted multicast stream, plus that portion of the access point bandwidth currently used for all existing downlink multicast streams, does not exceed the maximum internet protocol multicast bandwidth for the access point.

摘要： A detection-based defense to a wireless network. Elements of the infrastructure, e.g., access points or scanning-only access points, detect intruders by detecting spoofed frames, such as from rogue access points. Access points include a signature, such as a message integrity check, with their management frames in a manner that enables neighboring access points to be able to validate the management frames, and to detect spoofed frames. When a neighboring access point receives a management frame, obtains a key for the access point sending the frame, and validates the management frame using the key.

摘要： A system that enables network authorization status to be conveyed to the device requesting network services within or outside the scope of an authentication exchange is provided. The authorization status notification or information can be automatically generated or otherwise triggered by a request from the user or device. For instance, a query can be employed to solicit device authorization status related to a particular service or group of services. Additionally, authorization status notification can be automatically triggered based upon a change in the device authorization state.
