Study of fault tolerance in networks and distributed systems had its origins in early works in digital system design and testing. Over the years several dimensions of this area have emerged, encompassing almost all areas in electrical engineering, computer engineering and computer systems. Study of fault tolerance in WDM optical networks is a recent addition to the growing list of areas of interest in fault tolerance research. This project is aimed at advancing the state of art of research in fault tolerance theory for optical networks. Research will be carried out in two broad areas: Robust multiple failure recovery and multilayer survivability. By multilayer survivability we refer to the broad class of problems that involve logical topology design taking the impact of multiple failures in the physical topology into consideration. By robustness of a recovery mechanism, we refer to the ability of the recovery method to provide protection against a large number of multiple failures. We shall develop innovative algorithmic approaches based on advanced optimization techniques such as meta heuristics and approximation techniques, for problems in the three broad areas: (1) Quality of protection and robustness enhancement of single failure recovery methods, (2) Design of highly robust multiple failure recovery mechanisms and (3) Protection Interoperable design.

网络和分布式系统中的容错研究起源于数字系统设计和测试的早期工作。多年来，这一领域出现了几个维度，几乎涵盖了电气工程、计算机工程和计算机系统的所有领域。WDM光网络中的容错研究是近年来越来越多的容错研究领域中的一个新成员。本课题旨在推进光网络容错理论的研究现状。研究将在两个大的领域进行：稳健的多故障恢复和多层可生存性。对于多层可生存性，我们指的是涉及考虑物理拓扑中的多个故障的影响的逻辑拓扑设计的广泛类别的问题。通过恢复机制的健壮性，我们指的是恢复方法针对大量多重故障提供保护的能力。我们将基于元启发式和逼近技术等先进的优化技术，针对以下三个方面的问题开发创新的算法方法：(1)单故障恢复方法的保护质量和健壮性增强；(2)高度健壮的多故障恢复机制设计；(3)保护互操作设计。
