Routing and Wavelength Assignment (RWA) with Power Considerations In All- Optical Wavelength-Routed Networks

Routing and wavelength assignment (RWA) is an important problem that arises in wavelength division multiplexed (WDM) optical networks. Previous studies have solved many variations of this problem under the assumption of perfect conditions regarding the power of a signal. In this paper, we investigate this problem while allowing for degradation of routed signals by components such as taps, multiplexers, and fiber links. We assume that optical amplifiers are preplaced. We investigate the problem of routing the maximum number of connections while maintaining proper power levels. The problem is formulated as a mixed-integer nonlinear program and two-phase hybrid solution approaches employing two different heuristics are developed

Regents Outreach and Economic Development Task Force Meeting

Let me begin today by thanking you, Regent Hassebrook, as Task Force Chair, and each of you who is a member of this Task Force, for focusing on outreach and economic development at the University as we work on behalf of Nebraska. We thank Regent Chair Howard Hawks for appointing this task force. The level of commitment this shows for the university's role in outreach and economic development is very important both to us in the university and to Nebraskans.
