Management is a critical issue in optical networks.
Highly impacting in management, routing in optical networks, is
often decoupled into both the path selection and the wavelength
assignment problems. In the former, shortest path based
approaches are often applied to compute paths. Although such
approaches offer advantages in terms of network loading, they are
restricted by the fact, that routes are selected without taking into
account parameters pertaining to any explicit and desired service
guarantees. Thus, the wavelength assignment process may assign a
non-optimal wavelength with respect to incoming traffic
requirements and any associated quality of service specifications.
This paper addresses the lightpath selection problem by proposing
a novel route selection scheme where routes are determined based
upon the twin criteria of minimizing the number of hops and
balancing the network load, resulting in a reduction in both
network congestion and blocking probability.
