Multi-layer virtual topology design in optical networks under physical layer impairments and multi-hour traffic demand

Sengezer, N.; Karasan, E. (Optical Society of America, 2012-01-09)

In this paper, we consider the virtual topology design (VTD) problem in multi-protocol label switching (MPLS)/wavelength division multiplexing (WDM) networks with an hourly changing traffic pattern, in the presence of ...
Static lightpath establishment in multilayer traffic engineering under physical layer impairments

Sengezer, N.; Karasan, E. (Optical Society of America, 2010-08-09)

This paper investigates the lightpath establishment problem in the optical layer, which arises in multilayer traffic engineering. The static version of the problem is considered, in which the set of requested lightpaths ...
