Wavelength-division multiplexed networks using wavelength-routing are considered to be potential candidates for the next generation of wide-area backbone networks. In these networks, messages are carried in all-optical form using lightpaths. ATM is a widespread architecture and it is natural to exte
## Abstract A network is said to be survivable if it has sufficient capacity for rerouting all of its flow under the failure of any one of its edges. Here, we present a polyhedral approach for designing survivable networks. We describe a mixedβinteger programming model, in which sufficient slack is
