A distributed architecture for U-messaging systems.

摘要

This research describes a Distributed Architecture for U-Messaging Systems (DAUMS). With the explosion of the Internet and the increasing complexity of business today, Information Technology (IT) developers and project managers have to work harder and harder to find ways to develop a Universally Unified Messaging System efficiently. Obviously it is a challenge to create a well-defined architecture for such a system. DAUMS is an architecture that is created because of the need for a Universally Unified Method Invocation (UUMI). As the need for a universal portal has grown considerably, it has also created the need for connecting all the communication media in a seamless fashion. Users want to listen to their phone and email messages in one phone call. They want to read their emails and their faxes on the same Web browser. In summary, they want their email, faxes, phone messages, video conferences, and real time messages connected together. Not only will DAUMS provide a solution to these problems, it will create a standard that can be shared by all developers.; DAUMS architecture will support clients such as: browser, User Interface (UI), telephone, wireless and so on. It will be a hybrid between Java 2 Enterprise Edition (J2EE) and Windows DNA, and it will handle synchronous and asynchronous message mechanisms. As we create this architecture, we will look at all the pros and cons of other emerging distributed architectures for Web Services. Also, a Universal Messaging Application Framework will be created using this architecture to show how the DAUMS Architecture can be used to develop an application system.; This work can be used as a tool for IT managers, developers, project leaders, programmers and researchers. In addition, the framework can provide a starting point for developers and project managers; they do not have to start from scratch when building a Universally Unified Messaging System, which we will call U-Messaging system. The framework will work jointly with Universal Description Discovery and Integration (UDDI) to provide unlimited Web Services access to clients.
