ACE / / / ACE ACE X/OPEN DTP RSA I ACE Abstract Along with the development of computer network technology and distributed applications going deep into use, Client-Middleware-Server Three Tier model has emerged as the dominant computing paradigm in the decade, which has replaced the Client-Server model. Message-oriented middleware (MOM) is a special middleware based on message-transmission, and it provides effective and reliable message transmission for communication across heterogeneous platforms, and it carries through integration and interoperability of the Distributed System. Message-oriented middleware can easily implement the retractility and the expansibility of the Distributed System. ACE is an object-oriented toolkit, which implements basic design patterns of the communication software. It simplifies the development of object-oriented network software and services, which use IPC, events demultiplexing, directly dynamic link and concurrent mechanism. In this paper, after synthetically analyzing ACE toolkit and X/OPEN DTP model, and integrating a series techniques (RSA algorithm etc.), we firstly put forward a Message-oriented middleware product MOSMQ software which applies to asynchronous, fallible network and heterogeneous platform. We analyze the correla
