Design of WDM Networks: An Analytical Approach

Chi (Kyle) Guan

WDM technology has revolutionized the optical network by enabling huge increases
in the capacity of a single fiber.  The introduction of OXC based switching
enables the nodal architecture to support the transit of express waves without
unnecessary OEO regeneration, thus it allows carriers to provide new value in
their networks by reducing both capital and operational expenditures.  As
networks are evolved to meet the continued growth of traffic, a designer needs
to make fundamental choices of the network architecture.  In the current
telecom environment, the decisions are guided by network cost and scalability
concerns.

This talk summarizes our research on finding a new analytical framework, at a
high level, to identify cost-effective topological architectures of
OXC-switched WDM networks.  We first study the design of the network physical
topology under deterministic (static) traffic.  We next investigate the
topology design and resource dimensioning of OXC switched WDM networks in the
presence of statistical variability of traffic demand.
