HACMP技术及其在移动网络中的应用

HACMP Tecnology and Its Application in Mobile Network

采用具有较高处理能力的HACMP群集系统已成为移动网络设备设计的首选平台,主要介绍了HACMP的技术原理,包括双节点群集拓扑结构,多管理模块机制、多种资源调度机制、心跳和IP地址接管机制;分析了HACMP是如何实现在多机环境下抗御单点故障的技术机制。在此基础上,针对移动通信网络设备高可用性应用需求,给出了在HACMP环境下的资源配置方式和应用监控机制,提出了一种采用HACMP群集系统做为本地SCP节点的移动智能网容灾应用方案,对高可用性的移动网络设备设计具有一定的现实指导意义。

High Availability Cluster Multi-Processing（HACMP） is the first choice for the design of mobile network devices.This paper describes the HACMP technical theory including binodal cluster topological structure,multi-management module mechanism,scheduling algorithm about multi-resources and heart beat and IP address takeover mechanism.It also analyzes how HACMP prevents one point breakdown in multi-processing environment,and presents a method of resources allocation and application monitor mechanism.In addition,a new design for disaster tolerant system application in mobile intelligent network is given,which can satisfy the mobile network device high availability requirements.
