Computer network architecture and software engineering

In this paper we use software engineering methods and Shannon´s communication model to investigate computer network architecture. We get a new type of computer network architecture and some significant conclusions. At the first phase of the life cycle of software engineering, that is, requirement analysis, we get a series of unexpected conclusions. For example, a variety of computer network architectures could be established and evaluated. And the best architecture could be derived. What is more, protocol stack/framework could be established and evaluated in order to satisfy special function demands. If the other phases of the life cycle of software engineering are executed, the end system and router (switches) in special OS environment could be achieved.
