Abstract
This paper overviews network design issues of the photonic transport
network (PTN), which employs wavelength division multiplexing (WDM) and
wavelength routing. The design issues are considered on the level of newly
created high-speed transmission access paths, i.e., optical paths (OPs). These
include the routing and wavelength assignment (RWA) problems involved in
making the best use of network resources such as wavelengths and fibers. With
this objective, design issues for ring and meshed type PTN are addressed by
presenting the results of case studies in which existing heuristic RWA
algorithms were employed. By utilizing the design tools, the possible network
scale is then estimated,while considering state-of-the-art hardware
realization technologies. Further consideration is given assuming an
environment where PTN serves as a high-speed IP-backbone. An extensive case
study shows the cost-effectiveness of IP-over-PTN over other scenarios such as
IP-over-(point-to-point) WDM.
