Abstract

In recent years, network applications and hardware technology have been developed in impressive speed. That is, a large-scale network switching system is needed to satisfy all demand among network service providers and population, such as data, voice, image, video on demand, videoconferencing, telecommunications, remote control and teaching, etc. A general large-scale network switching system cannot fulfill various application needs, such as the correctness of data transmission and the capacity of extension for input/output port of switching system. In this paper, we propose a nested ring-based architecture to build a very large-scale network switching system. In order to satisfy the various network application needs, a nested ring-based architecture is designed as a switching element. It can make input data exchange fast to the destined output port, and input/output port of switching system can easily be extended up to 100 ports or 1000 ports to construct a very large-scale network switching system. The simulation results show that a better performance can be achieved in data transmission, delay, throughput and extensibility for the proposed system.
