摘要： In an example embodiment, a method is provided that receives a broadcast of available bandwidth from a first routing device. A congestion of traffic is detected along a downstream path to a second routing device. This second routing device is an immediate downstream neighbor. As such, an alternate path is established to the second routing device by way of the first routing device based on the available bandwidth in the network and a portion of the traffic is transmitted along the alternate path.

摘要： In an example embodiment, a multicast tree is accessed. The multicast tree defines one or more destination label switch routers and paths from a source label switch router to the destination label switch routers. Multicast addresses are then transmitted to the destination label switch routers. In an example embodiment, upon receipt of the multicast addresses, a request to update the multicast tree is transmitted. The request includes the identifier of the label switch router that originated the request.

摘要： In an example embodiment, a method is provided that receives a first label from an area border routing device. Here, the first label is associated with a first routing device, which is an immediate downstream neighbor of the area border routing device. The first label is then associated with a second label that is associated with a second routing device. In an example, the first label is received from the area border routing device along a path. Data that includes the second label subsequently is received and the second label in the data is replaced with the first label upon a failure of the area border router. The data then is encapsulated in an alternate path to the first routing device.
