Problems solved by technology

[0009] (1) Need to occupy additional hardware resources;
[0010] (2) The dedicated hardware circuit lacks flexibility. When an application process restarts abnormally on the board, the hardened hardware circuit may not be able to detect the restart. At this time, the configuration information of the board has been lost, causing the bus

Abstract

The invention discloses a single board configuration self-recovery method and device in a distributed system, and relates to the technical field of the communication. The method comprises the following steps: a main control board sends configuration information of each single board to a corresponding single board, and caches the configuration information of the corresponding single board; the main control board determines whether the fault has been occurred before in the single board according to the before state and the current state of the single board; if determining that the fault has been occurred before in the single board, the previously cached configuration information is sent to the single board so that the single board can recover the single board service. By accurately detecting the single board fault, the previously cached single board configuration information is sent to the corresponding single board so as to guarantee the normal recovery of the single board service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a single board configuration self-recovery method and device in a distributed system. Background technique [0002] A packet transport network (Packet Transport Network, PTN) device in a communication system is usually a distributed system, and the system includes a main control board, a backplane and several single boards. The single board includes virtual single board and physical single board, wherein: the virtual single board does not occupy the physical slot, and its agent process runs in the main control central processing unit (Central Processing Unit, CPU); the physical single board communicates with the main control unit through the backplane The boards are connected to each other, and related programs run independently on the physical board. In a specific application, the management plane and control plane programs of the main control board send configuration me...
