Signaling of the multi cast and the bidirectional uni- cast in single root multipoint servicing which uses RSVP TE

摘要

Being the multi cast of the down stream with the root and at least one leaf and manner in order to establish the joint of the uni- cast of the rise stream and the down stream, transmitting the label of the uni- cast of the aforementioned down stream where the aforementioned root and aforementioned one leaf takes the configuration of tree die at least, aforementioned manner, aforementioned at least from thing and the aforementioned root which generate the label of the uni- cast of the down stream to one leaf, generates inside the same signaling message as the label of the multi cast of the down stream and the label of the uni- cast of the rise stream, and, the manner which is includedSo it is. The network node which includes the label of the uni- cast of the down stream such as that, is used in order to run the above-mentioned manner. Choice figure Drawing 1
