Research on New Types of Network Architecture

Present practical network architectures are all constructed with layers. But with the rapid development of Internet, the limitations of layered network architecture are more and more outstanding. The layered structure makes it difficult to introduce new technologies, standards and protocols into existing network architecture. In addition it is an urgent problem to be resolved that the redundant operation in the different layers causes the performance of the network to drop. To resolve the limitations of layered network architecture, new types of network architecture arise. This paper presents three new types of network architecture: Object- Oriented Network Architecture, Service Unit based Network Architecture (SUNA) and Role-Based network Architecture (RBA).
