Embodiment Construction

[0035] In the present invention, in order to automatically complete the bidirectional forwarding detection (BFD) configuration in the network, all devices to be added to BFD send a request message to join the BFD group to a designated device in the BFD group, and the designated device sends a request message to the device to be added. The BFD device returns the address of the original device in the corresponding BFD group. At the same time, the original device in the BFD group learns the address of the device to be added to the BFD group. Then, the device to be added to the BFD group and the original device in the BFD group It automatically completes the BFD configuration and establishes the BFD connection with the pre-configured template. The template contains other relevant information required to complete the BFD configuration except the address of the opposite device, such as the sending interval, the receiving interval, and the multiple of local detection.

Abstract

This invention discloses a kind of auto-configuring method in the bidirectional retransmitting detection in order to deal with the problem of the huge work and the frequent error when it comes to the BFD configuration of the net equipment in current technology; this method recalls the equipment which is waiting to join the BFD group to send the requirement to the assigned equipment in the net; then the assigned equipment sends back the relating address of the original equipment to the waiting equipment, and sends the address of the waiting equipment to the original equipment in the net; at last, the BFD configuration is finished and the relating BFD connection is set up. At the same time, this invention also discloses a kind of net equipment and communication system.

Description

technical field [0001] The invention relates to the communication field, in particular to an automatic configuration method and system for bidirectional forwarding detection. Background technique [0002] With the gradual acceleration of the unification of data, voice, and video services into one IP network, it is the general trend to carry real-time, delay-sensitive services such as the next-generation network NGN and the third-generation network 3G on the IP network. How to quickly detect link faults The fault state becomes the key to solving the problem, and the bidirectional forwarding detection (BFD) technology emerges as the times require. [0003] The goal of BFD is to provide light-load (implemented on the forwarding plane, not occupying CPU resources) and short-duration (meeting carrier-class requirements - 50 ms) detection of channel failures between adjacent forwarding devices. These failures include interfaces, data links, and possibly even the forwarding engine...
