Device and method for realizing high availability in communication system

Abstract

The unit includes HH-OP to interexchage data of platforms in communication system, interruption interface and abnormal trigger device to process interrupting application and abnormal trigger signal, HA-OA to monitor local task and line operation and to carry out heartbeat detection, HA-ARB cosisting of platform decision device to decide abnormal trigger signal that can not be processed by HA-OP, task decision device to decide to switch or restart as per detected result of HA-OA. The present invention provides hardware redundant resource and handling method of data and state consistancy at standby time of software management redundance to realize HA requirement of telecommunication system.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a device and a method for realizing high availability (HA) in a communication system. Background technique [0002] Although the current systems with high reliability are different in the structural design of software and hardware, there is an independent system in the overall structure. This independent system is usually called a secondary system or a management system, and its task is to help other subsystems in the entire system to coordinate with each other, better realize functions, and meet high reliability requirements. The standard for measuring HA is the ratio of the system's uptime to this time plus the downtime (total working time). The usual requirement is to achieve 5 nines, or 99.999%, that is, the annual downtime is 5.25 minutes. [0003] The current HA system is basically designed from two aspects of hardware platform and software to improve the HA character...

Problems solved by technology

In hardware implementation, provide as much hardware redundancy resources as possible (nodes, networks, disks); in terms of software management, general solutions provide applications with consistent and complete data access, including: volume management, file system , online data backup, etc.; provide process guards, guard local tasks, and maintain guarded tasks. This method considers the operation of a single machine, and does not consider the solution of data consistency and state consistency during redundant backups. approach, not completely satisfied with the implementation of HA in redundant systems

For the high HA requirements of telecommunication equipment, due to the lack of certain management and coordination for HA of hardware and software, no matter which solution (including the simultaneous use of the two solutions) of the existing technology is adopted, it may not be possible to guarantee that HA of the telecommunication system can be realized Require
