Problems solved by technology

When the service board of the aggregation layer device fails, all services connected to it will be interrupted
At the same time, a single service processing board will cause service interruption when upgrading the aggregation layer equipment
[0003] For this reason, some inter-board protection technologies have emerged, such as LAG (Link Aggregation Group, Link Aggregation Group). However, this protection technology has some bottlenecks and defects, and it can only protect the relevant business traffic on the device, and for BFD detection traffic and alarms cannot be handled well

Embodiment Construction

[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] The present invention provides a method for protecting BFD by using multiple boards, such as figure 1 As shown, in the first embodiment, the method for protecting BFD by using multiple boards includes:

[0037] Step S100, setting a main service processing board and at least one backup service processing board.

[0038] The interface card of the BFD device is set with multiple boards, and the selector of the BFD device sets one of the multiple boards as the active service processing board, and the other multiple boards as the standby service processing board The main service processing board is used to implement bidirectional transmission of services between the main BFD device and the remote BFD device, and the standby service processing board is mainly used as the service reserve board for the main serv...

Abstract

The present invention provides a method for protecting BFD by using multiple boards, which is applied to BFD equipment, by setting a main business processing board and at least one backup business processing board; detecting whether the main business processing board is offline, If so, then one of the standby service processing boards is switched to a new main service processing board; receive BFD messages and non-BFD common IP forwarding messages from the interface card; send the BFD messages to The new active service processing board and other standby service processing boards deliver the non-BFD common IP forwarding message to the new active service processing board. The invention also provides a device for protecting BFD by using multiple boards. The beneficial effect realized by the method for protecting the BFD by using multiple boards provided by the present invention is to quickly, efficiently and stably perform inter-board protection for the BFD, so as to ensure that the business does not interrupt.

Description

technical field [0001] The present invention relates to the field of bidirectional transmission detection, in particular to a method and device for protecting BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) by using multiple boards. Background technique [0002] With the development of science and technology and the times, Ethernet technology has gradually become an important technical means of social production and office. In particular, with the rapid growth of smart terminal holdings, the mobile Internet industry is also becoming more and more mature. The development of wireless networks to All-IP (all-IP) networks requires more equipment at the aggregation layer to have large capacity and a fast service response mechanism to ensure that services are never interrupted and highly reliable. Traditional Ethernet aggregation layer equipment is usually equipped with one service processing board and multiple service interface cards, which has certa...
