HACMP Tecnology and Its Application in Mobile Network

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.
