Duplicated hot-redundancy method of telephone dispatching device in distributed system architecture

Abstract

The invention discloses a dual-machine hot backup implementation method applied to telephone dispatching equipment, which includes a service board, a main machine control board and a standby machine control board. The steps include: a. The control board and the service single board are connected based on the TDM HW bus; b. There are two control mechanisms between the two main control boards in the master-standby relationship: hardware switching and software switching; c. The software running on the two main control boards is completely Consistent, the standby machine can regularly and real-time synchronously back up the host business data and running status functions. The invention has simple hardware configuration and low system cost, and the application of the invention can effectively improve system security and stability; the telephone dispatching device of the present invention is connected to the digital program-controlled switchboard through E1, and can complete all access to the dispatching device based on the local phone Telephone dispatching service, including teleconferencing, telephone transfer, telephone pickup, hotline and other functions.

Description

technical field [0001] The invention relates to the field of telephone dispatching equipment, in particular to a dual-computer hot backup method for telephone dispatching equipment with a distributed system framework. Background technique [0002] Telephone dispatching equipment is a telecommunications device that can realize telephone dispatching services. It is widely used in office seats in command posts, office seats in duty rooms, and console seats in dispatching rooms. Its reliability and continuity are crucial. At present, many key scheduling devices have a redundant mechanism of active / standby dual-machine hot backup on the hardware. Two identical machines with a mutual active / standby relationship work at the same time. Once the main machine fails, the system can automatically switch, and the standby machine takes over from the old main machine. Become a new working host to ensure uninterrupted communication services. In recent years, telephone dispatching equipment...

Problems solved by technology

[0005] Dedicated software method: Applied to the distributed system hardware architecture, deploy and run different hot backup control software on the main machine and the standby machine. Open the connection with the original host, then connect with the standby machine, and finally update and read the data and status of each service board by the standby machine. This method obviously does not meet the requirements for scheduling equipment with high real-time requirements and fast business response speed, and the The method needs to manually determine the main machine and standby machine and install different software during the initial deployment, and the execution efficiency is too low
