 Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
 Image 6 It is a flowchart of the method of the present invention. As shown in the figure, the method includes the following steps: S1: The carrier network node builds an IPv6 hierarchical forwarding tree network topology based on congestion control by itself to reduce the probability of node congestion; S2: node When congestion occurs, the traffic distribution between parent and child nodes is redistributed through multicast congestion notification messages, and combined with the IPv6 protocol, the notified node can transmit messages according to the corresponding redundant routing addressing method to transfer the traffic in the congested area. Move to other areas with lighter load to avoid the congested node; S3: After the node is relieved of congestion, multicast the congestion release message to restore the parent and child ...
