Proportion-aware IP over hierarchical WDM ring networks

Wavelength division multiplexing (WDM) appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. It has the scalability problem with increasing the access node numbers in WDM ring architecture, so we further propose the alternatives of hierarchical WDM ring architecture. Since the traditional IP provides the best effort service only, the issue of supporting IP packets with QoS transfer has become a crucial issue for multimedia transmission. We do so by addressing the proportion-aware QoS model. Finally present performance analysis multiple classes of hierarchical WDM ring networks.
