Technology Research And Applications For The Com-based Distributed Object

This paper analyzes principles of distributed object technology based on COM/DCOM/COM+ in detail, discribes COM' s thread model, comraunicaiton protocols and security mechanisms, and presents formal model of software components reuse in COM. After load balancing and some classical algorthms are thoroughly discussed in distributed system , a new algorithm of load balancing is devised.The implementation of three-tierdistributed ERP system based on COM is given at last.
