We study the problem of joint spectrum and storage resource backup (JSSRB) to improve the survivability of elastic optical datacenter networks (EODNs) for cloud services. An ILP model and heuristic algorithms are developed. Simulation results show that JSSRB can effectively improve the survivability and spectrum efficiency of EODNs.
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...
