    Abstract: Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. An example method includes sending a multicast receiver route received from one of a multicast service processor or a provider edge router to another of the multicast service processor or the provider edge router, wherein the multicast service processor is communicatively coupled to the provider edge router via a multicast control plane topology that is non-congruent to a unicast control plane topology, and replicating multicast data received from the other of the multicast service processor or the provider edge router to the one of the provider edge router or the multicast service processor based on the multicast receiver route.

    Abstract: A method and system for routing traffic in an IP network using OSPF protocols and including core and hub routers in area zero. The core and hub routers are assigned different node signatures depending on whether the router is a core router or a hub router and link signatures match the node signatures. Internode traffic (core to core, hub to core, and hub to hub) is configured with routing algorithms separately for node and link network segments for which node and link signatures include core signatures as well as those of the internode pair selected. The OSPF routing for the separate network segments is then used to route traffic over the network. An IP network so configured will not route core traffic over hub links during periods of core element failure or downtime, and suffer packet loss.

    Abstract: A method is provided for setting up a communication from a first edge node, across a network that uses direct virtual path routing, to a second edge node. The first edge node receives a request to set up the communication. The second edge node is identified as the destination of the communication, based on the request. A first virtual path identifier (VPI) is obtained that defines a first path from the first edge node across the network to the second edge node. A second VPI is obtained that defines a second path from the second edge node across the network to the first edge node. The first and second VPIs are selected by a routing status database. A first virtual channel identifier (VCI) within the first VPI is selected. A second virtual channel identifier (VCI) within the second VPI is selected. Data is transmitted from the first edge node to the second edge node using the first VPI and first VCI, and from the second edge node to the first edge node using the second VPI and second VCI. Switches adapted to carry out the method are also provided.
