Embodiment Construction

[0049] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0050] Such as Figure 5 As shown, a buffer area is pre-allocated on the protection board for each protected board to save the pre-configured data of the protected board. Different from the above-mentioned prior art 2, what is stored in the protection board is not the pre-configuration command of the protected board, but the result of parsing the pre-configuration command, that is, the pre-configuration data. Using pre-configuration data facilitates the use of incremental pre-configuration commands to add, delete, and modify pre-configuration data.

[0051] The content contained in the full pre-configuration command includes: protected board number, configuration data type and configuration data; the parsing process is: save the configuration data to the pre-configured data buffer area corresponding to the protected board number corresponding to the c...

Abstract

This invention disclose a method and a device for protecting inversion of branch channel units including the following steps: a master control board sends a pre-arrangement order to a protection board by total quantity method, which analyses the order to arranged data and stores them. When the master control board detects the data of a protected board have been revised, it sends the revised part to the protection board by increment, which analyses the order to revise the original data correspondingly and stores them. When carrying out TPS, the protection board takes out the pre-arranged data to match the protection board based on the protected board number. The device includes a master control board, a protected board, a protection board, the master control board includes a total quantity send unit and an increment send unit, the protection board includes total quantity receive/process units, an increment receive/process unit, an order analysis unit and a data process unit.

Description

technical field [0001] The invention relates to an optical network technology, in particular to a branch unit protection switching method and device. Background technique [0002] TPS (Tributary Unit Protect Switch) is a device-level protection switching mode, that is, when the protected board fails, the protected board can be used to replace the protected board to work. How to shorten the service interruption time and quickly restore the service during the tributary protection switching process is a key index of TPS. [0003] In a network system including a main control board, a protection board, and a protected board, the main control board is a single board for implementing operation and maintenance functions. A protection board refers to a service board that is configured with a TPS protection relationship and is in a protection status. The protected board refers to a service board configured with a TPS protection relationship and in a protected position. [0004] fi...
