Methods and systems for resource management in a fast packet switching communication network are disclosed. A packet containing an address field identifying a source endpoint and a destination endpoint is received. A bandwidth constraint based upon the source endpoint, but independent of the destination endpoint, is enforced for the packet. In a communication network wherein a plurality of virtual connections are provisioned from a single source endpoint to a plurality of destination endpoints, the bandwidth constraint is associated with bandwidth usage over all of the virtual connections.

A method and system for providing user access to complex information through interactive voice dialog. The computerized method includes the provision of a memory and storage in the memory of a plurality of selected words which may be recognized in predetermined phrases and dialogue contexts when spoken by users. A voice template is further stored in memory having selected information slots in corresponding frames. Each of the slots and frames is adapted to be continuously filled by recognized words. User speech utterances are initiated for receipt by the computer which requests complex information or responds to generated queries. By continuously receiving and comparing the user speech utterances to the stored plurality of selected words, slots and frames of the voice template are filled. Based on the context of the interactive dialogue and the extent of recognized vocabulary words, responsive speech segments are generated which provide the requested complex information or, alternatively, request additional information necessary to provide a full response to the user.

A method is disclosed for automatically collecting and delivering multimedia application event data in an interactive network. The interactive network includes a server and a plurality of client stations. In operation, an event of a multimedia application at a first client station is identified. An event data signal representing the event is then transmitted and received by the server. The server processes the event data signal to determine if it is interested in the event. The server stores the event data signal if it is interested in the event. The server also allows other client stations to register an interest in the event. Upon determining an event of interest to a client station, the server automatically delivers the event data representing the event to the interested client station.

A method is disclosed for identifying corrupted speech signals in a call receiving mode of a voice messaging system. The method includes the step of receiving a message signal. The message signal represents an audio message. The method next includes the step of determining a signal quality. The signal quality is then compared to a threshold. If the signal quality is at least as great as the threshold, the audio data representing the message signal is stored in a memory. If the signal quality is not as great as the threshold, an indication signal is transmitted indicating that the signal quality is poor. A system is also disclosed for implementing the steps of the method.

A scheduling system is disclosed for scheduling tasks for fulfilling a series of service requests. When each service request is received, a determination is made as to the amount of resources a task requires to provide the requested service. Further, a preferred time within which to perform the task is obtained from the requestor of the service request. For each service request, data for the estimated amount of resources and the preferred time are supplied, on a first-come-first-serve basis, to a scheduling component for solving a combinatorial optimization model which efficiently allocates a predetermined amount of resources for each time slot in a scheduling period by rearranging tasks for service requests previously received. The scheduling component provides for a service requestor, without regard to subsequently received service requests, a service time in which to perform the task for the requested service substantially immediately after the service request is made. Whenever possible, the service time coincides with the preferred time. Each previously received service request will have its related task performed within the service time provided to the requestor of the service request. The scheduling system is particularly useful in scheduling technician time for service calls received by customer representatives in the telecommunication and utility industries.

A method and system for controlling traffic in selected links of the Public Switched Telephone Network (PSTN) through the use of variable price incentives. The number of selected PSTN links which are available for use are determined at a predetermined time through the use of an appropriate traffic measurement system. Thereafter, a customer usage rate is determined for the selected PSTN links. The determined rate corresponds to the number of selected links which are available for use. An electrical signal is generated for receipt by the user and which contains information corresponding to the determined customer usage rate.

A service for screening outgoing telephone calls. The service allows a subscriber to determine the times of day and/or days of the week when she wants her outgoing calls on her telephone line to be restricted to numbers which have been approved by her. Calls to numbers other than those on the authorized list will not be completed. Incoming calls are also restricted and a privileged caller code must be entered for the outside caller to complete the call to the subscriber.
摘要:
A method and system for generating an optimized solution for assigning traffic loads to channels in SONET rings in cooperation with a computer having sufficient memory. The method and system utilize a Mixed Integer Program (MIP) having corresponding variables necessary to model the cost of Terminal Multiplexers, Add/Drop Multiplexers and corresponding interface ports necessary to route the desired traffic loads. By routing traffic loads to reduce computation time and imposing mathematical bounds on the MIP variables, the number of possible MIP solutions is reduced. The Mixed Integer Program is minimized in accordance with the traffic routing and imposed mathematical bounds such that an electrical signal is generated which corresponds to the optimized traffic load assignment information. The signal is converted to digital format whereupon it may be retrieved from computer memory and displayed to the user.

A method for developing a network analysis and modeling application program includes the step of interactively selecting and displaying a graphical object. An instantiation of the graphical object is representative of at least a portion of a network. The graphical object is further used in an executable network analysis and modeling application program. The preferred embodiment further includes the step of editing the selection of the graphical object.
