Abstract
All-optical network technologies employing wavelength division multiplexing (WDM) will play the major role in constructing large bandwidth networks. Since such networks require not only transmission line capability enhancement, WDM should be utilised in combination with wavelength routing. The function of routing must be implemented for reaching high connectivity and flexibility of optical network. This paper presents a proposal for a WDM optical networks suitable for high capacity traffic. Two different approaches supporting optical paths will be described: wavelength path (WP) and virtual wavelength path (VWP). The paper focuses on the comparison of WP and VWP in terms of non-hierarchical transport system with blocking and non-hierarchical transport system with waiting queue.
