Abstract

This work deals with routing schemes in SDH/SONET-WDM multilayer networks applying Synchronous Digital Hierarchy (SDH) or Synchronous Optical Network (SONET) on top of a dynamic photonic network in Wavelength Division Multiplex technology (WDM). The focus are integrated routing schemes which benefit from an integrated view of the SDH/SONET layer and the optical layer. Besides the comparison of known non-integrated and integrated methods, the new routing scheme Weighted Integrated Routing (WIR) is presented and its performance evaluated. In contrast to other known integrated routing schemes, WIR uses rating functions to evaluate different path alternatives and select the best route. In addition to the analysis of the different routing schemes, the dimensioning of network resources is treated.
