Data center networks recovery for large-scale disasters in optical cloud networks

With the growth of cloud computing and data center (DC), data center networks (DCNs) is becoming an increasingly important part in the future networks. However, large-scale disasters are considered as the main problems in terms of network survivability. Therefore, we propose a data center recovery algorithm to protect the majority of customer service as soon as possible. This algorithm can maximize time efficiency in maintaining network connectivity compared with traditional algorithm.
