We consider the problem of designing an MPLambdaS network of optical cross-connects (OXCs) to interconnect a given number of label switched routers (LSRs). We present a set of heuristic algorithms to address the combined problem of physical topology design (i.e., determine the number of OXCs required and the fiber links among them) and logical topology design (i.e., determine the routing and wavelength assignment for the lightpaths among the LSRs). Unlike previous studies which were limited to small topologies with a handful of nodes, our heuristic algorithms can be applied directly to networks with hundreds or thousands of LSRs and can accommodate a number of lightpaths that is an order of magnitude larger than the number of LSRs. We present numerical results for a wide range of system parameters such as the number of wavelengths per fiber, the number of transceivers per LSR, and the number of ports per OXC, which provide new insight into the design of MP$\lambda$S networks.
