Abstract: A fast convergence method of point to point services and the provider edge device thereof. The method comprises: a. setting the route information of at least two tunnels whose start node is the PE the farend CE dual-attached to and the end node is the PE the farend CE connected with in the PE the farend CE dual-attached to; b. detecting the status of the tunnel to obtain the tunnel status information; c. the PE the farend CE dual-attached to obtains available route information according to the tunnel status information and the preset route information of the at least two tunnels and forwards the services according to the available route information. The PE the farend CE dual-attached to of present invention can forward the services directly according to the preset route information of other tunnels when the tunnel is unavailable such as the end node of the tunnel occurs abnormal, so that the route reselection is avoided, the convergence speed of the point to point services is increased and the reliability of the services is improved.

Abstract: A message transmission method and apparatus based on DUA protocol comprise: setting the protocol identification information respectively corresponded by different signaling system protocols; the transmitting side transmits the message needed to transmit and the protocol identification information corresponded by the message to the receiving side; the said receiving side determines the signaling system protocol corresponded by the message received by the receiving side according to the protocol identification information received by the receiving side. The present invention can make the message of different signaling protocols use the same interface of the network device to transmit. It avoids the message of different protocols from necessarily transmitting via different interfaces so as to achieve the purpose of economizing the interface resource of the network devices and reducing the cost of the system group network.
