Abstract: Methods and apparatus to manage bypass paths in an Internet protocol (IP) network are disclosed. An example method disclosed herein includes receiving IP traffic at an aggregation router and measuring a bandwidth value of the IP traffic forwarded from the aggregation router to an IP router at a starting node. The example method also includes establishing a first non-routed bypass path between a switch at the starting node and a first switch at a first destination node when a measured traffic throughput value of the IP router at the starting node exceeds a first threshold value, and sending the IP traffic from the aggregation router via the bypass path.

Abstract: A method and apparatus for providing communication for virtual private networks in networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) are disclosed. The present method enables Service Border Routers (SBRs) to perform mapping of VPN routes between two or more autonomous systems based on Virtual Route Forwarding (VRF) tables configured on each Autonomous System (AS). The method configures cross-connect tables in SBRs for coupling one or more VRF tables in one autonomous system with one or more VRF tables in other autonomous systems.

Abstract: A method and apparatus for enabling congruent multicast and unicast routing in a Virtual Private Network (VPN) are disclosed. For example, the present method receives a request to join a multicast group to receive multicast data traffic by a receiver behind a remote Provider Edge (PE) router. The method then discovers a multicast source to allow said remote PE router to use a direct path to receive said multicast data traffic from a source.

Abstract: Example methods and apparatus to dynamically store network routes for a communication network are disclosed. A disclosed example method involves receiving data via a router having a first memory to store active routes and a second memory to store inactive routes. A destination address associated with the data is identified and in response to detecting that no destination address entry stored in the first memory matches the destination address associated with the data, a default route stored in the first memory is selected to forward the data using a multicast transport protocol.

Abstract: A backbone network may include first and second border routers and a route reflector. The first border router may provide data connectivity between the backbone network and a first regional network. The first border router may be configured to receive a notification of a change in status of an edge router of the first regional network, and the notification may be received according to a first routing protocol. The first border router may be further configured to redistribute the notification of the change in status of the edge router from the first routing protocol to a second routing protocol with the first and second routing protocols being different. The second border router may provide data connectivity between the backbone network and a second regional network. The route reflector may be coupled between the first and second border routers, and the route reflector may be configured to transfer the redistributed notification from the first border router to the second border router.

Abstract: In one embodiment, the present invention is a method and apparatus for scalable virtual private network multicasting. In one embodiment a service network builds a new data multicast distribution tree for each high-bandwidth multicast data flow (e.g., multicast data flows that require an amount bandwidth meeting or exceeding a predefined threshold). However, if the multicast data flow is a low-bandwidth flow (e.g., if the required amount of bandwidth falls below the predefined threshold), the multicast data flow is routed over an existing multicast distribution tree in order to minimize an amount of state information that must be maintained by service provider core routers in the backbone network.
