Routing and Wavelength Assignment in Optical Networks

Routing and wavelength assignment strategies in optical networks

We consider the routing and wavelength assignment (RWA) problem on wavelength division multiplexing (WDM) networks without wavelength conversion. When the physical network and required connections are given, RWA is the problem to select a suitable path and wavelength among the many possible choices for each connection such that no two paths using the same wavelength pass through the same link. ...

P - 2535 Routing and Wavelength Assignment in Optical Networks

The problem of routing and wavelength assignment (RWA) is critically important for increasing the efficiency of wavelength-routed all-optical networks. Given the physical network structure and the required connections, the RWA problem is to select a suitable path and wavelength among the many possible choices for each connection so that no two paths sharing a link are assigned the same waveleng...

[Proceeding] Power-Aware Routing and Wavelength Assignment in Optical Networks

We introduce the Power-Aware RWA problem, whose goal is to accommodate lightpaths in wavelength routing networks minimizing the power consumption. Formulation, algorithms, and results are presented, showing that significant power savings are possible. Introduction Wavelength Routing (WR) networks offer the flexibility of designing a “logical topology”, comprising lightpath requests, over a phys...
