TUNNEL ESTABLISHING METHOD, NETWORK NODE DEVICE AND NETWORK SYSTEM

摘要

A network node device, a network system and a tunnel establishing method, the method is that the network node device for providing the aggregating link and passed through by the Multi-Protocol Label Switching Tunnel determines the physical bandwidth resource for establishing the Multi-Protocol Label Switching Tunnel according to the aggregating link physical member bandwidth during establishing the Multi-Protocol Label Switching Traffic Engineering Tunnel. Since the Multi-Protocol Label Switching Traffic Engineering Tunnel is tied dirrectly to the physical port and the link aggregating is a measure for increasing the bandwidth, at the same time of ensuring that each of the Multi-Protocol Label Switching Traffic Engineering tunnels can obtain the bandwidth allocated by the control plane in the retrasmition plane, by utilizing the bandwidth of the link aggregating adequately and carrying as much as traffic of the Multi-Protocol Label Switching Traffic Engineering, the link bandwidth can be increased with the link aggregating technique.
