Abstract
Cloud computing depends critically on large data centers connected by a high-speed optical network. A fault-tolerant communication scheme to handle requests for communication in such a system is essential. In this paper we have proposed an optimal approach to the problem of developing a path-protection scheme to handle communication requests in data center (DC) networks. We have formulated our problem as an Integer Linear Program (ILP). We have studied our approach using simulations, varying parameters, such as the number of DCs, and the number of disasters. Our simulations show that considering additional disasters do not add significantly to the cost of the solution, which means significant resource savings while supporting users' demands.
