Embodiment Construction

[0031] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] The present invention provides a method and system for switching a single board to realize main board switching, so as to meet the requirement of single board protection switching. Realizing active / standby switchover is close to a pure software method, and single-board self-negotiation can be completely completed by single-board software.

[0033] The method for realizing active-standby switchover of a single board in the embodiment of the present invention includes:

[0034] Establish inter-board communication channels between each board and other boards;

[0035] When active / standby switchover is required, each single board selects a single board to be used from the single boards applying for main use through mutual negotiation among the single boards, and sets the single board to be used as the main board.

[0036] The...

Abstract

The invention discloses a method and a system for realizing the main / standby switch of single boards. The method comprises the following steps: establishing an inter-board communication channel between each single board and any other single board; and when main / standby switch is required, electing the single board to be mainly used among the single boards applying for main use according to the mutual negotiation of the single boards, and setting up the single board to be mainly used.. Because of not being required to control the single board interference, the mode for realizing the main / standby switch of single boards avoids the risk of main / standby switch failure due to the faults of controlling the single board, lowers the complexity of the system, saves the construction cost of the system, and ensures that the system structure is relatively simple and the whole realizing mode is simple and feasible.

Description

technical field [0001] The invention relates to a method and a system for realizing main-standby switching of a single board. Background technique [0002] With the rapid development of optical network technology, SDH (Synchronous Digital Hierarchy, Synchronous Digital System), OTN (Optical Transport Network, Optical Transport Network) and other communication protocols and WDM (Wavelength Division Multiplexing, wavelength division multiplexing) technologies are gradually mature. The protection requirements of communication lines are getting higher and higher. Protection switching is proposed under such conditions. The general method of protection switching is: add some redundant backup boards to the system. When a board in the system is abnormal, the backup board can take over the work of the faulty board in the shortest time, that is, through active and standby switching. business protection. [0003] There are many types of service protection. For example, for cross-con...
