   abstract   = {We address the problem of routing Label Switched Paths
                  (LSPs) in multi-layer networks based on the Generalized
                  MultiProtocol Label Switching (GMPLS) paradigm. In
                  particular, we pursue strategies for choosing the
                  appropriate layer to host a new LSP request, since choosing
                  this policy has enormous impact on the eventual performance
                  of the network. Therefore, we developed a mixed strategy,
                  the Min-phys-hop routing and wavelength assignment
                  algorithm, as a policy to govern the selection of the best
                  layer of a multi-layer network in which to host new LSP
                  requests. In this paper, we discuss the practical issues
                  concerning the deployment of this algorithm in modern GMPLS
                  networks. Firstly, we discuss the applicability of the
                  algorithm with respect to the state-of-the-art GMPLS
                  standards, above all, the GMPLS routing extensions to
                  OSPF-TE. We also sketch two possible reference deployment
                  scenarios. Secondly, we present simulation studies to
                  demonstrate that (1) there does not exist a universally
                  optimal static layer-preference policy and (2) the
                  Min-phys-hop algorithm realizes an adequate heuristics even
                  considering the realistic limitations of contemporary
                  network devices. We found that the Min-phys-hop algorithm
                  produces close-to-optimal blocking and resource consumption
                  under almost all possible selections of input parameters,
                  and this is regardless of the wavelength and
                  Optical-Electrical-Optical (OEO) conversion capability
                  present in the network.}
