Micro-communication Architecture Based On The Vc Model

Since the 1990's, there has been extensive research in the area of high performance network architecture among the network community. However, that research commonly depends on the conventional hierarchical networking architecture. Although the networking performance could be further improved, the problems concerned with the inherent limitations of the hierarchical architecture are still difficult to be resolved. To overcome such limitations and improve poor network service efficiency, which is mainly due to the redundant function overlaps between neighbouring layers and complicated hierarchical processes existing in the conventional hierarchical network, by analysing and classifying network services, a novel network architecture called the service unit based network architecture (SUNA) were presented.. This project is realized on the model of packet , after analyzing the demands of network performance, we decide to form the Micro Communication Element System(MCES) based virtual circuit to overcome the quality of service. We take the virtual circuit scheme because the network architecture based packet switching can not overcome the quality of service .The virtual circuit scheme will finish the low efficiency of network and the bad quality of service. So after we accomplish the model of packet, we begin to design and realize the model of virtual circuit. This dissertation mainly show the plan of the MCES based virtual circuit on the PC platform and linux OS, and the test of its performance. we point the main characteristic of MCES based virtual circuit, tell how to establish ,transmit, maintenance and remove the virtual circual, analyze how the virtual circuit is formed between the host and the router .
