General Equipment Management System Under The ATCA Platform-based Design And Implementation

Since the telecommunication industry entered the3G era, the amount of data beingprocessed has increased greatly. In order to guarantee the high performance of dataprocessing, carrier-grade operating system and hardware platforms based on ATCA（Advanced Telecom Computing Architecture）are applied. How to design anequipment management system for ATCA platform has become an important issue tothe development of telecom middleware.After studying a variety of standards and specifications that support modularcommunications platform, the paper gives a deployment program of telecommiddleware. And the functional requirements of equipment management module areconcluded with analysis on the construction of the telecom middleware. As a coresubsystem of the telecom middleware, the common equipment module and othermodules, realized the management of the common equipment which satisfied the ATCAstandards.The following contents are the main object of studying the common equipmentmanagement system.First, in the use of redundancy technology, the module meets high availability ofthe system. System uses the active-standby mode, active node offers services, andstandby node has the ability to repl the active node smoothly. Then the thesis analyzeshot-swap and the modification of node status. With ARP cheating, it achieved the IPtakeover while hot-swapping. This paper discusses how to solve the problem of datasynchronization between two hot-swap nodes. It proposes a method of using the shareddisk. At the same time it should use RAID technology to guarantee security andreliability of the shared disk.Second, two user-interf modes, command-line mode and RPC model, are designed.Command-line mode includes two types of commands, inquiring andsetting, but in the RPC mode the system and other system could work togetherthrough the method of remote procedure call.Third, in order to monitor equipment’s real-time failure, it provides two methods. One is the cycle of polling. The middleware sends a health inquiry to all equipments ona regular basis. The other is the SNMP trap method, which uses SNMP to send real-timedevice status information to the management system. Then this paper discusses theprocess of fault analysis and handling.After the test of the system, it demonstrated that the system could meet the needsof common equipment management based on ATCA. And the availability of thetelecommunications middleware is improved.
