A network management apparatus is described which includes a port for connecting to a network for receiving management data from network devices on the network. The network management apparatus includes a processor for processing the received management data and for determining substantially a complete topology of the network and providing image data representative of the network topology. The apparatus further includes a display for receiving the image data and displaying a graphical representa...

A network comprises an IEEE 1394 sub-network serving as a wire-communication system at the high-level layer, and a plurality of radio-communication terminals (radio-communication nodes) which form DHCP clients. The IEEE 1394 sub-network constitutes an in-home LAN (Local Network Area). The IEEE 1394 sub-network includes antenna base stations each serving as a DHCP server. The antenna base stations have a pool comprising a predetermined number of addresses which are assigned automatically to radio...

A method and apparatus for improving dynamic simple network management protocol GetNext processing is disclosed. The method and apparatus supports dynamic information in SNMP by building the "GetNext" list once, then caching that list for a given amount of time.

A system and method for filtering of web-based content in a proxy cache server environment provides a local network having a client, a directory server and a proxy cache server that caches predetermined Internet-derived web content within the network. When content is requested, it is vended to the client only if it meets predefined user policies for acceptability. These policies are implemented based upon one or more ratings lists provided by content rating vendors. The lists are downloaded to t...

A method of controlling data transfer between a first and a second computer network comprises parsing content description language received from the first computer network to determine tag information with the content description language. A completion decision is made based on the tag information. For one embodiment, the completion decision may include any of the following: full data transfer between the two network, partial data transfer between the two network, a deferred data transfer at a l...

In a hierarchically organized distributed file system, resources belong to the containers in which they are located. These resources do not have to be co-located with the, containers in which they are stored, but can be distributed over the file system. To locate a desired resource, the unique name of the resource is determined. Moving upward through the containers in the hierarchically organized distributed file system, the lowest container with a location service is determined. The location se...

An invention is disclosed for a control module, executed as part of an application, that includes application-specific strategies for the application, yet can be coded using the JAVA programming language. In one embodiment, a system for providing application-specific strategies to a JAVA platform is disclosed that includes a runtime subsystem and an application, which includes a control module in communication with the runtime subsystem. The application further includes a plurality of service mo...

A network identification system for use in a process control system creates and stores a unique network identification tag for input/output networks in the process control system. During the configuration process, each process controller is assigned a unique controller identification tag. In addition, each input/output device installed on each process controller is assigned a device identification tag. The network identification system creates a network identification tag for an input/output net...

In a digital telecommunications network having first and second addressing zones, a name and address server in the first addressing zone receiving from a first address of the first zone, assigned to a source machine, a request to provide an address in relation to the name of a destination machine situated in the second addressing zone, sends to a second address of the first zone a first packet containing at least the said name of destination machine, said second address of the first zone being a...

A multi-tiered server management architecture is employed including an application development tier, an application operations tier, and a cluster operations tier. In the application development tier, applications are developed for execution on one or more server computers. In the application operations tier, execution of the applications is managed and sub-boundaries within a cluster of servers can be established. In the cluster operations tier, operation of the server computers is managed with...
