Classification based tunnel selecting method and apparatus

The invention discloses a tunnel selecting method and an equipment based on category, which is used for realizing selecting a TE tunnel according to service priority. The method of the invention comprises the steps as follows: at least two TE tunnels are established beforehand on a controlling layer to every peer node; the two TE tunnels are bond to be a tunnel group; the TE tunnel established onthe controlling layer is correlative to the service priority; a transmitting layer tunnel group and the corresponding relationship among the TE tunnel and the controlling layer tunnel group and the TEtunnel are established according to the service priority; the tunnel group established by the controlling layer and the corresponding TE tunnel are sent to the transmitting layer according to the corresponding relationship; In the transmitting layer, tunnel group is selected according to an object IP address, and then corresponding TE tunnel is selected according to the transmitting layer tunnelgroup which is established
