<p>The core idea of the method for transferring a data message on the TE tunnel and a node device is to determine the transit node needed to switch the MPLS TE tunnel, to set a routing forward information by which the different MPLS TE tunnels switch the tunnels and to switch and transmit the data message in the different MPLS TE tunnels by the transit node according to the routing forward information. The sum of the whole network edge band width resource is higher than the band width resource in the core of network, the network resource is converged layer by layer, the problem of N square amount of the tunnels is avoided, and the pressure on the network core node caused by a great deal of tunnels and the state renewing pressure of the RSVP-TE are alleviated; the method for setting up a route forwarding information for switching the MPLS TE tunnels is simple and easy to realize; thereby realizing the aim that the requirement for the network resource converged layer by layer is satisfied, the utilization of the band width resource and the extensibility of network are increased.</p> |
