The explosive growth of communication demands in recent years has attracted special attention to the issue of reliability of telecommunications infrastructure and backbone networks. The importance of large-scale failure problems in communication networks cannot be overstated. Such failures could paralyze the backbone networks and completely disrupt essential network-based voice and data services across the country. Fast and cost-efficient recovery of communication service is essential in today's world. A number of different options for network restoration exist, including local (link-based) restoration or end-to-end (path-based) protection, using shared or dedicated capacity, offering different restoration times and redundancy costs. The main objectives of this research proposal are to analyze the impact of large scale failure scenarios arising from security attacks or natural disasters on the telecommunication infrastructure, and to design multi-layer restoration schemes, methods and algorithms for integrated protection and traffic restoration of access, metropolitan and backbone layers of the network. Survivable topology design, cost analysis, and administrative and management issues related to large-scale failure recovery in the communication infrastructure are among the topics that will be tackled in the proposed research program.
