Research On Agent Of CDMA TMN And Implementation Based On JDMK

This paper discusses analysis and design of agent in CDMA IS-95 TMN and its implementation based on JDMK, which includes information modeling, cluster collaboration, transaction processing and common management information service . A new kind of information modeling method is supported with component and container technology of JDMK/MBean, and information model's data storage and its information search are optimized by the means of virtual and actual managed object, active object and non-recursive search arithmetic. For the promotion of performance and reliability of key task/transaction of agent, the article merges technology of agent and cluster, and discusses three kinds of cluster relation between agents: dynamic collaboration, load share, error control. Based on JDMK, their solution is discussed. In order to ensure integrality and consistency of information model's operation, nested transaction and distributed transaction in agent is researched. On the basis of characteristics of transaction, two kinds of arithmetic is designed, which are reverse search for state of child transaction and improved 2-Phase-Commitment Protocol. The execution of CMIS is optimized by thread pool and object flow, and performance of agent is analyzed through test.
