Research And Implementation Of High Available System For Bill Record Collection

Bill record collection system is the key subsystem of Internet access accounting system, which is responsible for collecting the bill record produced by accounting system. The Bill Record is the accounting token of Internet Access Service Provider, so the accuracy of the bill record collection system is very significant.This thesis is to design a bill record collection system with hot spare through researching the HA (high availability) technology and bill record collection. The currently existing HA (high availability) software (such as Windows Cluster, Rose HA, Sun Cluster) is not very good to be used for building a bill record collection system with hot spare. This thesis researches and designs a cluster management software with an external communication interface, which can be used smoothly to build the hot spare of bill record collection system.This paper includes six parts. The firs part analyzes the status of bill record collection system in accounting system, and the accuracy of bill record collection. The second part argues for the adoption of active-standby hot spare; analyzes the approaches to improve the availability of active-standby hot spare system. The third part, through researching the currently existing HA software and analyzing the availability of the bill record collection system, designs a cluster management software which is more advanced than the currently existing software. The fourth part designs a bill record collection system cooperating with cluster management software. The fifth part designs and realizes the whole system using ACE and 00 method. The sixth part concludes the work of this thesis and put forward the further job of this system.
