The method also includes automatically converting the network topology data into route targets to be assigned to virtual routing and forwarding elements. The route targets are grouped into sets and duplicate sets of route targets are removed based on the route targets between duplicate sets of route targets identified as being the same. The method further includes generating a data record including information related to the set of route targets.

Abstract: Policy-based routing of packets over a peer-to-peer, quality of service connection includes sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device. Packets originating from an application requiring a specified level of service are transmitted, from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection. Packets originating from an application that does not require the specified level of service are transmitted, from the source peer implemented on at least one device, over a best effort connection.

Abstract: Systems and methods for testing an implementation of a routing protocol in a device are disclosed. Generally, a sequence of protocol messages is provided and a test is performed to test how a device reacts to a specific playback rate for the sequence of protocol messages, wherein the specific playback rate causes a protocol state transition in the device which differs from an expected protocol state transition absent a specific playback delay.

The connection is disposed internally within the multi service platform.

Abstract: Communication between a source and a destination is dynamically established. A connection request is received. The connection request is based on a request transmitted over a best-effort path from the source. A network connection is established having a specified quality of service (QoS) based on the request between the source and the destination. Data for a first application is transmitted over the network connection and data for a second application is transmitted over the best-effort path.

Abstract: A subscriber dynamically establishes a peer-to-peer session from a source subscriber to a destination subscriber across a switched virtual circuit (SVC). A signaling (control) connection is established from the source subscriber to a server, and a connection request is sent via the signaling (control) connection to the server requesting establishment of the SVC to the destination subscriber. In response, a database is queried for information about a source switch associated with the source subscriber and a destination switch associated with the destination subscriber. Subsequently, the connection request is forwarded to a proxy signaling agent, and the proxy signaling agent signals the source switch and the destination switch to dynamically establish the SVC connection from the source switch to the destination switch. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A frame relay data rate RFR for a VoIP call is determined based on a particular packetization time interval TS and its associated sample data size BS for a particular CODEC, a size BHT of at least one of a frame relay header and a frame relay trailer, and a size BIP of an IP header. A number of VoIP calls NUMVOIP that can be supported by a frame relay access link is determined based on a bandwidth of the frame relay access link that is to be allocated to VoIP traffic, and the frame relay data rate RFR. At least one network parameter is determined based on NUMVOIP. Bandwidth in an asynchronous transfer mode (ATM) network is allocated for the VoIP traffic based on the at least one network parameter.

Abstract: The disclosed method and system provides a new service provision interface that allows operator use without requiring many of the specific technical network details, such as VRF, RT, SOO, route redistribution, etc. Further, the translation from a customer's requirements (including both VPN topology membership requirement and L2, L3 requirement from customer) into technical network configuration commands are handled using an automated method that is transparent to the operator. In a particular illustrative embodiment of this patent disclosure, a high level table with reduced technical detail is generated by an operator and an automated provisioning system, without operator visibility or required operator interaction, creates intermediate data including network specific technical information in an automated process to generate a deployable network topology including VRF and RT assignments for use in network provisioning.

Abstract: An SVC is established via an ATM switch port, which includes multiple virtual paths (VPs), by associating multiple virtual user-to-network interfaces (UNIs) to each of the VPs. Each of the VPs includes multiple virtual circuit (VC) ranges, each of which corresponds to a different virtual UNI. Each VC range includes at least one VC for control and at least one VC for data transfer. Associating the virtual UNIs to each of the VPs includes mapping each virtual UNI to a corresponding VC range within a VP based on a virtual path index (VPI)/virtual channel index (VCI) of the virtual UNI initially received by the ATM switch port.
