Abstract:
A virtual private branch exchange (PBX) system that routes calls within a packet-switching network. Login information is received from a data device. The login information includes an alias identifying a user at the data device and a network address identifying the location of the data device on the packet-switching network. The virtual private branch exchange system associates the user's private branch exchange extension with the network address and routes calls to the user's (PBX) extension to the data device on the basis of the network address of the data device.
Abstract:
A Network Alarm Monitoring System for monitoring messages generated by network elements that provides for a great degree of configuration and reliability. Via a display interface, e.g., Web-based or otherwise, clients may create and configure text-based rules for monitoring alarms. These rules are applied to specify which actions are to be taken on which messages, based on designated field values of alarm messages. Actions include writing messages to an alarm database, sending messages to downstream network management systems, triggering an e-mail or page. Furthermore, remote access to the network element being monitored is provided.
Abstract:
Disclosed is a system that prevalidates service orders that are placed by an inter exchange carrier with a local exchange carrier for connection of the inter exchange carrier with a business customer. An integrated prevalidation system and service order system is disclosed in which prevalidation requests are performed using the data that is entered for the service order. Prevalidation responses are then used to ensure that the order will be correct when submitted, thereby avoiding, the necessity for expensive supplemental orders. Further, the present invention allows for stand alone prevalidation requests which enable a provisioner to determine availability of circuits, and to determine location information and equipment identification directly from the LEC databases. Further, the present invention is capable of reconciling the database of the inter exchange carrier with the database of the LEC to avoid submission of incorrect service orders. Further, auditing reports can be generated whenever a prevalidation response has been accepted and a service order acknowledgment has rejected the service order. These reports can be used to audit and obtain credit for the necessary supplemental orders which may follow. Also, prevalidation requests are reserved to prevent submission of conflicting service orders.
Abstract:
A system and method for reliabe delivery of datagram protocol data unit (PDU) packets generated by a network oriented application at a first computing network element to a second computing network element across a network. The method steps include: at the first computing network element, capturing generated datagram packets destined for the second computing network element; determining a size of a payload associated with the datagram and communicating the size of the payload to the second computing element via a reliable connection-oriented transport service PDU; communicating the actual payload to the second computing element via the reliable connection-oriented transport service PDU; and, at the second computing network element, utilizing payload size and payload to reconstruct a datagram PDU including the payload for a network application at the second computing network element. By this technique, reliable datagram PDU transport over the network is ensured.
Abstract:
A method and device for preventing fraud in international calls in a long-distance telecommunications system, where selected customers can avoid fraud control blocks and greater granularity is achieved in blocking international destinations. In the method and device, an override flag is created in the records of the Billing Number Screening (BNS) database. When a call is made using a billing number whose corresponding record has the override flag set, the call is not stopped by fraud control blocks on certain international destinations. In addition, international destinations can be blocked with greater specificity because a Country Set Logic (CSET) field is added to the International City Code Database. The addition of CSET to this database allows particular international city destinations to be blocked from certain origin points.
Abstract:
A system controls the flow of traffic in a network, especially an Ethernet-based network. The system receives a flow control message indicating that traffic flow to a downstream device is to temporarily cease and determines an appropriate flow control action based on a set of control policies in response to the flow control message. The system then performs the selected flow control action.
Abstract:
An interactive telephony services system is provided with instant communications function. In accordance with some embodiments, presence information related to the availability of a called party to be contacted via instant communications affects the handling of telephone calls to the called party. In accordance with some embodiments, a telephone call may be connected to an instant communications client used by a called party.
Abstract:
A network architecture in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers that are connected by access links to CPE edge routers belonging to the one or more VPNs. To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic. Granting precedence to intra-VPN traffic over extra-VPN traffic in this manner entails special configuration of network elements and protocols, including partitioning between intra-VPN and extra-VPN traffic on the physical access link using layer 2 multiplexing and the configuration of routing protocols to achieve logical traffic separation between intra-VPN traffic and extra-VPN traffic at the VPN boundary routers and CPE edge routers. By configuring the access networks, the VPN boundary routers and CPE edge routers, and the routing protocols of the edge and boundary routers in this manner, the high-level service of DoS attack prevention is achieved.
Abstract:
An intelligent network provisioning system (20) has a client platform (22) with a user interface for order entry. A server platform (24) is connected to the client platform (22) by a network (26). The server platform (24) is capable of sending a query to a calling card provisioning system (28). An application server (30) upon receiving an order from the server platform (24) downloads the order to the intelligent network (32) and transmits a state change message to the server platform (24).
