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 sta...

Embodiment Construction

[0060] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0061] Aiming at the high requirement of telecommunication equipment on HA management system, the HA management device and method of the embodiment of the present invention solve the realization of HA management in a system with high requirements on HA characteristics (using hardware and software to achieve high availability).

[0062] figure 1 It is a schematic diagram of the principle of the HA device in the system in the embodiment of the present invention. There are two nodes in the system of the embodiment of the present invention, working in 2N redundancy mode. In different systems, there are different hardware platforms and operating systems. The HA software can run on different operating systems and hardware platforms after minor modifications. In the em...

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...
