摘要：The high data transfer capacities of current wavelength division multiplexing optical networks put large amounts of data at risk of getting corrupted in the presence of faults and attacks. A wide range of techniques for handling component failures in transparent optical networks are already available in the literature. In recent years, there is growing recognition of the need to develop suitable mechanisms for reducing the adverse effects of malicious attacks such as high-power jamming and tapping attacks. A number of recent papers have proposed static lightpath allocation approaches that take such security issues into consideration. However, most of these approaches consider the routing problem separately from the wavelength assignment problem. In this paper we propose a new security-aware scheme for the complete dynamic routing and wavelength assignment (RWA) problem. Unlike previous approaches, we consider both in-band and out-of-band attacks under dynamic traffic scenario and present an integer linear program (ILP) formulation with two possible objectives for solving the security-aware dynamic RWA problem. For larger networks we present an efficient heuristic algorithm SA-DRWA (Security-Aware Dynamic Routing and Wavelength Assignment) that aims to minimize both in-band and out-of-band attacks. To the best of our knowledge, this is the first such formulation to jointly consider in-band and out-of-band attacks, for dynamic traffic
