摘要： In one embodiment, a system may determine receiver identifiers to identify affected receivers, where each of affected receivers failed to receive a packet identified within a packet stream. A loss signature may identify the packet. Each of the affected receivers may be identified by a corresponding one of the receiver identifiers. The system may also determine a packet loss location of the packet from a network topology tree. The network topology tree may include a model of a logical network over which the packet stream was transmitted from a stream source to the affected receivers. The packet loss location may correspond to a lowest common ancestor node of at least two of the affected receivers.

摘要： Methods and apparatus are disclosed for end-to-end ATM calls based on the interworking of ATM SVC signaling (such as private network-network interface signaling) with A.2630.1 AAL2 signaling. In one network, Q.2630.1 AAL2 signaling in the originating access segment triggers, on proper authentication, ATM SVC signaling (e.g., PNNI, IISP, AINI, etc.) in the core, which triggers Q.2630.1 AAL2 signaling in the terminating access segment. The triggering is done at the edge-core boundary where an AAL2 switch and/or multiplexer or an ATM switch with AAL2 multiplexing/switching capabilities is located. In the access network between the ATM-AAL2 edge switch and the edge gateway, multiplexed AAL2 virtual channel connections (VCCs) are typically used. Single-CID AAL2 SVCs are typically used in the core network, and between the ATM-AAL2 edge switch and PSTN trunk gateways. The binding of voice calls to ATM bearer channels is done at the edge gateway when triggered by a call agent.

摘要： Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for establishing a call across a network. For example, the network may include a first edge switch, a second edge switch, and an ATM core network coupled to the first and the second edge switches and configured to allow the second edge switch to communicate with the first edge switch. The second edge switch, being responsive to a received Q.2630.1 AAL2 message, is configured to send a first Private Network-Network Interface (PNNI) setup message to the first edge switch as part of establishing a call between or through one or more of the first and the second edge switches.
