Abstract: An implementation of a routing protocol in a device is tested by testing how the device reacts to messages and message sequences having potentially adverse conditions. Examples include messages either having a specified message size which is intentionally out-of-conformance with the routing protocol, having a repeated protocol field, absent a mandatory protocol field, or having an incorrect order of protocol fields. Examples also include message sequences having either a specific playback delay between at least one pair of adjacent protocol messages in the first sequence of protocol messages, a specific playback rate for the second sequence of protocol messages, or a modified message order.

Abstract: A system is disclosed for detecting paketization delay of packets in a network. The system includes a router to receive at least one packet containing data. A detection system, which is in communication with the router, extracts a codec information and a packet length information from the packet. A management system, which is in communication with the router, receives the codec information and the packet length information and determines packetization delay based on the codec information and the packet length information.

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: An ethernet wide area network (10) has a number of interconnected network ethernet switches (12). A first local area network (18) has a first local area ethernet switch (16) and is connected to one (14) of the interconnected network ethernet switches (12). A second local area network (24) has a second local area ethernet switch (22) connected to a second (20) of the interconnected network ethernet switches (12).

Abstract: A multi service platform including a layer two switching component and a layer three switching component is connected to a layer two network and a layer three network. The layer two switching component is a terminating point for the layer two network, whereas the layer three switching component terminates the layer three network A virtual UNI connection is established between the components increasing reliability of end to end connections across the networks, and simplifying provisioning of these types of networks.

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.

Abstract: An SVC is established between a client and a host by dynamically configuring a host CPE device using a custom module designed for the host CPE device. The configured host CPE device enables communication between the client and the host via the SVC connection.

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.
