Abstract:
A mechanism for segregating traffic amongst STAs that are associated with a bridge, referred to herein as the personal virtual bridged local area network (personal VLAN), is based upon the use of a VLAN to segregate traffic. The IEEE 802.1Q-1998 (virtual bridged LANs) protocol provides a mechanism that is extended by the invention to partition a LAN segment logically into multiple VLANs. In the preferred embodiment, a VLAN bridge forwards unicast and group frames only to those ports that serve the VLAN to which the frames belong. One embodiment of the invention extends the standard VLAN bridge model to provide a mechanism that is suitable for use within an AP.
Abstract:
A gateway device is disclosed for deployment at user premises, which offers applications services similar to those of a server from the premises, albeit managed by a service management center via the network. For each application service, gateway programming provides application server communication with a client functionality of an endpoint device, for the respective service, communicated on top of network layer communications within the premises and through the wide area network. The application service logic in the gateway device also enforces authorization, authentication, configuration, or use of the service via the endpoint device. Management of the application service is responsive to communications with the service management center via the wide area network. A gateway device of this type, for example, may offer PC or TV type user interfaces. The gateway also may establish peer-to-peer communications with other similar devices.
Abstract:
A disclosed service management system communicates via wide area network with gateway devices, located at respective user premises. The service management system remotely manages delivery of application services by the gateway device(s), e.g. by selectively activating or deactivating service logic modules in the gateway devices. The service management system also may selectively provide secure communications and exchange of information among gateway devices and among associated endpoint devices. An exemplary service management system includes a router connected to the network and one or more computer platforms, for implementing management functions. Examples of the functions include a connection manager for controlling system communications with the gateway devices, an authentication manager for authenticating each gateway device and controlling the connection manager and a subscription manager for managing applications services and/or features offered by the gateway devices. A service manager, controlled by the subscription manager, distributes service specific configuration data to authenticated gateway devices.
Abstract:
The disclosed examples of a multi-services gateway device comprise application service programming logically positioned on a user premises side of a logical network demarcation forming an edge of the wide area network at the user premises. The programming also defines a logical service provider-user demarcation between the user premises and the application service provider. The application service programming resides on the service provider side of the service provider-user demarcation and only provides a logical application service interface across that demarcation to deliver an application service to an endpoint device. The logical service provider-user demarcation also provides a demarcation in accessibility to hardware resources of the gateway device, whereby some hardware resources of the gateway device are on the service provider side of the logical service provider-user demarcation and are inaccessible to an endpoint device from the user side of he logical service provider-user demarcation.

Abstract:
In a managed repeater (10) having an address learn capability wherein receipt at a particular port (30) of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking circuit includes an address learn circuit associated with the particular port, for replacing the stored source address with the received source address when the stored source address does not match the received source address, and an address lock register for the particular port, coupled to the address learn circuit, for storing a bit value to disable the address learn circuit from replacing the stored source address with the received source address. This managed repeater provides improved security in a network having source address updating by allowing an administrator to disable the source address update for a particular port in the managed repeater. Each address lock register is externally programmable, and the administrator is able to program time windows to disable source address updating for a particular port. The administrator may program each address lock register independently to prevent the stored source address associated with each port from being updated. The managed repeater allows the administrator to determine on a per port basis whether the managed repeater's address learning capability should be enabled or disabled for a programmable time window.
Abstract:
A vital-signs patch for a patient monitoring system that includes a housing containing a sensor that makes physiological measurements of a patient, a transmitter, a receiver, a memory, and a processor. The processor periodically takes a measurement from the sensor, converts the measurement to a data record, and stores the data record in the memory. Upon receipt of a signal from another device, the processor retrieves at least a portion of the data record, converts the retrieved portion of the data record to a vital-sign signal, and causes the transmitter to transmit the vital-sign signal to the other device.
Abstract:
A disclosed service management system communicates via wide area network (WAN) (99) with gateway devices (10) at various user premises, to remotely manage delivery of application services and/or features thereof by the gateway device(s), based on service subscriptions of customers associated with the gateway devices. In the examples, a subscription manager (73) provides information through the WAN identifying the applications services or features to be enabled, to each respective gateway device. Also, a service manager (75), controlled by the subscription manager, distributes service specific configuration data to logic implementing server functionality for the application services in the gateway devices, responsive to requests from the gateway devices. The system also includes a gateway device updater (51), responsive to requests received from the gateway devices, for downloading service logic modules for implementing application services or service features to the gateway devices, via the wide area network, for application services or features identified by the service manager.
