Abstract: A method of assigning capacity and routing flow in a bi-directional line switched SONET ring based upon ring topology and demand data defines for each pair of links of the ring a two-edge cut. Each two-edge cut divides the ring into two sets of nodes. For each two-edge cut, the capacity assignment method calculates a demand equal to the sum of all demands between nodes on opposite sides of the two-edge cut. The capacity assignment method then determines the maximum demand and sets the capacity of each link equal to one-half the maximum demand plus one-half of one demand unit. The flow routing method of the present invention calculates a cut difference for each two-edge cut. A critical cut is a two-edge cut having a cut difference equal to or less than one. If there is a critical cut with demands greater than zero on the same side of the critical cut, the method performs a first processing routine.

Abstract: A method and apparatus for managing delivery of data, also referred to as “content”, by a data processing system in a communications system in which a number of content providers and content consumers are located within the communications system. The data processing system receives a request to accept delivery of content at the data processing system, wherein the request originates from a requesting content provider. A determination is made as to when the content may be received from the requesting content provider and when the content may be transmitted to content consumers based on contents already scheduled to be delivered from the number of content providers. Delivery of the content from the requesting content provider is accepted based on a determination of when the content may be received and when the content may be transmitted.

Abstract: A method and system for resilient internetwork connection of frame relay (FR) networks and/or end systems. For FR relay networks interconnected by a self-healing network, a standard protocol is provided which allows a resilient network-to-network interface NNI to automatically respond to physical interfaces failures detected by the self-healing network. Switching gateways in the resilient NNI, re-route further traffic to avoid the failed physical interface. In one embodiment, a simple set of interacting protocols and mechanisms control communication between FR/ATM gateways and ATM switches. Each FR/ATM gateway includes interworking function (IWF) processing modules for converting user data between frame relay packets and ATM cells and for processing status signaling messages to achieve a resilient NNI.

The developing and testing step takes a first amount of time.

Abstract: To revert the topology of a network to its original or normal state after an alternate route has been found for bypassing traffic away from a malfunctioned link that has since been repaired, an Operation Support System (OSS) sends to each of the custodial sender/chooser nodes and the tandem nodes that form the alternate route respective commands to revert the operation(s) that each node had performed during distributed restoration. The OSS is able to identify the custodial nodes by the fact that those nodes perform more operations than the tandem nodes. The operations that were performed during the distributed restoration process were recorded and the thus restored topology of the network is mapped and stored. Upon receipt from the different nodes that the malfunctioned link has been repaired, the OSS sends to each of the nodes a specific command to perform the inverse of the operation(s) that that node had performed during the restoration.

Abstract: A programmable gateway for processing protocol conversion for a virtual bearer channel platform. The platform includes a plurality of transaction processing units (TPUs). Each TPU processes service requests transmitted by a caller or transmits service requests to a destination called party. The platform has a distribution network that interfaces with the TPUs and acts as a shared bus between the TPUs. The platform receives and transmits communications with a communications network over bearer channels of a high bandwidth pipe. A cross-connecting controller multiplexes the signals coming into the platform over the bearer channels onto the distribution network, and also demultiplexes signals going out over the bearer channels from the distribution network. A resource manager provides a centralized control for the allocation of bandwidth to the transaction processing units.

Abstract: A configurable and scalable rules-based thresholding system, method and computer program product for processing event records includes a core infrastructure and a configurable domain-specific implementation.

Abstract: A method and system for processing a High level Data Link Control (HDLC) message despite the occurrence of a frame slip event in an Asynchronous Transfer Mode (ATM) receiver avoiding re-transmission of an HDLC message when a frame slip event occurs during reception of an HDLC message. In one embodiment, an ATM receiver receives an ATM cell, where the ATM cell carries one or more T1 payloads. Each T1 payload contains a plurality of timeslots, including an HDLC timeslot. The HDLC timeslot is read for each T1 payload prior to unloading each T1 payload from the ATM cell. The plurality of timeslots within each T1 payload are sent to a switch matrix, where the timeslots are de-multiplexed. The HDLC message is carried in the HDLC timeslot over a plurality of ATM cells and the HDLC message is processed despite the occurrence of a frame slip event.

Abstract: The present invention performs automated testing on service applications using automatically generated logs, so that new testing applications do not need to be created for each new release of a service application. The invention further provides for testing of all aspects of the service application by accounting for all data and processes performed, and does so without interfering with the processing of the service application. An Automated Regression Tester (ART) captures and records data generated by the execution of an initial version of a service application. This data is recorded to a first test log. When a new or ported version of that service application is developed, the first test log is used by the ART to generated output that emulates the operating environment, including caller and user input, of the service application. The processing of the new/ported version of the service application is captured and recorded to a second test log.

Abstract: An application program interface (API) provides an interface for application programs to communicate with a telephony server. The telephony server generates events regarding calling activity within a call center. The API receives these events and forwards them to the application programs. The API may be run on an agent workstation along with application programs. The applications register with the API to identify what types of events are of interest to the application program. The API receives the events from the telephony server and distributes the events according to the registrations.

Abstract: A system and method for placing articles of manufacture or pieces of equipment at a remote site uses a central database and graphical representations. A site hierarchy, comprising a site, a building at the site, and a floor within the building, is created in the central database. The user can then create graphical objects on a floor at a building, which are also represented in the central database as sequences of points. Specifically, graphical objects are created for a floor within a structure, a zone within the floor, a planning unit within the zone, a row segment within the planning unit, and a footprint (where the article or piece of equipment is placed) within the row segment. The central database can also store tabular (non-graphical) data, regarding the physical characteristics of physical objects (such as the actual area of a row), as well as particular information for each footprint (such as an installation date, an activation date, etc.).

Abstract: A personal authentication system provides at least two levels of security for an authentication process, in addition to numerous other security features. The system operates across many different software and hardware platforms, in a client/server fashion, employing a challenge/response process that does not require users to transmit their passwords across a network. An application running on a client computer is coupled with an application running on a server computer. The client generates a response to a challenge, which is provided by the server. The response is a combined function of the server's challenge, a serial number assigned to the client, and a password provided by the user.
