Embodiment Construction

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 1 It is a schematic diagram of a system configuration diagram of a multi-processing board system before switching according to an embodiment of the present invention. Such as figure 1 As shown, the system includes N+1 processing boards (where N is a natural number), and the physical board numbers are 1, 2, ..., N, N+1, and the board number is N+1 processing board (below (Referred to as the board N+1) is the backup board (shown by shading in the figure), and the remaining processing boards are the active boards. These processing boards are connected through a fast Ethernet switch board. In order to improve reliability, each processing board has two network ports, which are respectively connected to two mutually backup Ethernet switch boards.

[0019] It should be noted that the backup board is just a logical role. It can be assum...

Abstract

The provided N+1 redundancy backup method for multiprocessing boards with N activation boards and one backup board comprises: composing the activation boards into a logical ring by address mapping, and backuping some running data of former board in the next one on same ring. Wherein, it also provides a processing board that comprises a main memory accessed by processor on same board to store self running data and a backup memory accessed by processor on another board to store at least some running data on said board. This invention reduces cost.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to an N+1 redundancy backup method, a switching method and related processing boards, a multi-processing board system and a wireless network controller in a multi-processing board system. Background technique [0002] The existing communication system equipment is usually equipped with multiple processing boards, and in order to enhance the reliability and availability of the communication system, N+1 redundancy backup is generally implemented. That is, there are N processing boards working normally, and one processing board is used as a backup board. In the existing multi-processing board system, if a processing board fails, the following three situations may occur: [0003] Case 1: A stable call cannot be restored on the backup board. [0004] Case 2: Stable calls can be restored on the backup board, and the backup board has a larger memory to store all call context data on th...
