    摘要: A method to perform dynamic source selection within an IP multicast network is performed at a designated router of an IP multicast network. At the designated router within the IP multicast network, a first source of a multicast group is selected to be forwarded to a receiving host or multiple receiving hosts. The first source is monitored to automatically detect when the first source exhibits a predetermined characteristic. At the designated router, responsive to the detection that the first source exhibits the predetermined characteristic, a second source of the multicast group is automatically selected to be forwarded to the receiving host or hosts. The method also supports automatic selection of all normally operating sources and forwarding of the traffic of such sources or channels to the receiving hosts or hosts.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A method includes sending a data packet, or a copy of the data packet, from a first video distribution hub to a second video distribution hub. The first video distribution hub is coupled to a first link and to a second link. The method also includes, in response to the second link being intact, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a primary network path that includes the second link and excludes the first link.
