The present invention discloses a new paradigm in Multimedia Services Creation Methodology, and new Service Creation and Service Execution Environments, based on this methodology. A service designer can access the Service Creation Environment via a Web based Graphical User Interface (GUI), to design new service in an automated way. The design process includes creation of the Service Logic Script (SLS), and associated databases that are used for storage of service and subscriber related data. The service developer (user) assembles Language Graphical Objects (LGO) into Service Logic Script. LGOs are part of a new graphical language that has been developed to meet multimedia service creation needs. They represent service control and call control primitive functions that have to be performed, in order to provide a multimedia service to service subscribers.

An application provisioning device may be used to manage a profile of a host and provide data corresponding to a selected application for installation at a host. A reverse firewall may use the profile of the host to determine whether to allow or block particular network communication from an application running on the host. An indication of a selected application may be received at the application provisioning device. Configuration information may also be received at the application provisioning device. The application provisioning server may request an update to the profile of a host and transmit such a request. The profile may be updated to reflect the configuration information and/or information of the selected application. Data corresponding to the selected application may be updated and transmitted to a host computer, where it may be installed. Therefore, the installed application running on the host may operate without being prematurely blocked by the reverse firewall.

Reverse firewall with self-provisioning

A system and method for identifying computer system performance signatures and for identifying the cause of undesirable performance signatures, particularly with respect to both application-based and computer system-based parameters. Respective parametric information data is matched with corresponding parameters found in a stored plurality of reference signatures. If a match is found between the behavior of a computer system under study and a reference signature, the present invention provides information about the cause(s) of the reference signature, such that appropriate remedial measures can be taken. If a match is not found (according to predetermined matching rules), then the present invention may provide additional prompts to request additional information or test data such that the signature of computer system being tested can be further refined so that the signature of the target computer system might more closely match a reference signature.

System and method for diagnosing computer system operational behavior

A method and a system for forwarding multicast data packets across a plurality of telecommunications subnets interconnected by routers in which a data packet is received within a subnet of the plurality of telecommunications subnets. When the data packet is a multicast data packet, a multicast IP address for the multicast data packet is determined. A multicast forwarding database is accessed for determining a LAN Emulation Client associated with the multicast IP address, and a Broadcast Unknown Server associated with the multicast IP address for the multicast data packet is determined. The multicast data packet is sent to the Broadcast Unknown Server associated with the multicast IP address for the multicast data packet through the LAN Emulation Client using a point-to-point connection. The Broadcast Unknown Server sends the multicast data packet inter-subnet to each router associated with the multicast IP address for the multicast data packet using a point-to-multipoint connection, with at least one multicast host being connected to a subnet that is different from the subnet in which the multicast data packet was received.

IP multicast over routed ATM network using lane

In one embodiment of the invention, an apparatus is provided for establishing a communication session between first and second terminals in communication over a plurality of networks that employ differing transmission standards. The plurality of networks are selected from among a circuit switched network (e.g., a telephony network), a connectionless packet switched network (e.g., the Internet) and a connection-oriented packet switched network (e.g., an ATM or frame relay network). The apparatus includes a call set-up translator for translating among call set-up protocols associated with the circuit switched network, the connectionless packet switched network and the connection-oriented packet switched network. An encoding format translator is provided for translating among encoding protocols associated with the circuit switched network, the connectionless packet switched network and the connection-oriented packet switched network. Also provided is an address database for storing a plurality of addresses in different formats for each registered terminal, which includes the first and second terminals. The apparatus also includes a session manager for storing control information relating to the first and second terminals. The control information includes an identification of the first and second terminals that participate in the communication session.

Wan-based gateway

A method is disclosed for establishing communication between an originating station and a destination station over a computer network such as the Internet, for example. In accordance with the invention, at least one service attribute requested by the originating station is received over a signaling path. A communication path is then established between the originating and destination stations in conformance with the requested service attribute. The signaling path is an out-of-band signaling path with respect to the communication path.

Intelligent processing for establishing communication over the internet

A system and method that overcomes the deficiencies of prior television/multimedia system integrity monitoring schemes by providing a system and method wherein a remote field component receives a test signal from a given source via a particular signal path, and, in response, provides feedback indicative of the received test signal to the source via a standard voiceband telephone connection. This enables the invention to facilitate simple, economical real-time testing/monitoring of television/multimedia distribution systems. The invention is particularly suited to television/multimedia systems that employ terrestrial cables as a means to distribute signals to end-users or remote nodes, but can also be applied to wireless signal distribution systems.
