Problems solved by technology

At present, the 1:1 active/standby backup redundancy method and the 1:N backup method are generally used. These forms are not very flexible. If the data areas in all units adopt this 1:1 backup method, that is, a master unit There is a backup unit as the backup of its data area, which will greatly increase the n

Example Embodiment

[0026] The redundancy backup method of the present invention means that there are multiple units in the system, including N primary data units A1, A2,..., An, and M backup data units B1, B2,..., Bm, in unit A1 There are a1 data areas in the A2 unit, a2 data areas in the A2 unit, and so on, there are N such units, the last unit is An, there are an data areas in the An unit, and Nx is equal to a1+a2+...an , Nx data areas are used as the main data area, there are b1 data areas in the B1 unit, b2 data areas in the B2 unit, and so on in M ​​such units, the last unit is Bm, and there is bm in Bm Data areas, Mx is equal to b1+b2+...bm, and Mx data areas are used as spare data areas.

[0027] The data area can be backed up between the main and standby data areas. The entire Nx+Mx data area resources are managed by a main control unit Z, which has high reliability and redundancy measures. At a certain moment of system operation, at most N units in the Nx+Mx system can perform actual servic...

Abstract

The method includes following steps: multi units are set in the communication system above, which are divided into N main data units and M standby data units. Multi data regions are set in each unit. The data region in main units is used as main data region, and the data region in standby data unit is used as standby data region. A main control unit Z is set to control all data regions; when system has failure, the main control unit Z starts standby data region in standby unit to replace main data region and to be as main data region

Description

technical field [0001] The invention relates to the field of communication exchanges, in particular to a redundant backup method and device in an exchange system in the communication field. Background technique [0002] In the design of the switch, the distributed design method has become the mainstream of the switch design. How to ensure the stable and orderly work of multiple modules and units in the distributed design and improve the fault-tolerant performance of the system is very important. At present, the 1:1 active / standby backup redundancy method and the 1:N backup method are generally used. These forms are not very flexible. If the data areas in all units adopt this 1:1 backup method, that is, a master unit There is a backup unit as the backup of its data area, which will greatly increase the number of backup data areas. This backup method is a waste of resources, and the 1:N backup method has certain limitations. It does not meet the many-to-many requirements, and...
