Abstract

Due to the advances in technology, WDM optical networks employing wavelength routing are becoming a reality. The end-to-end networking of wavelengths in fully optical domain requires new design methods to enhance transmission and node processing capabilities. In this paper we studied the problem of designing a logical topology over a wavelength-routed all-optical network (AON) physical topology using heuristic logical topology design algorithm (HLDA). For a given network physical topology and traffic pattern (relative traffic distribution among the source-destination pairs), our objective is to design the virtual(logical) topology and the routing algorithm on that topology so as to maximize single(virtual)-hop traffic flow and congestion will be reduced. This HLDA also solve lightpath route selection (LPRS), lightpath wavelength selection (LPWS).
