Design and Implementation of Optical Cloud Networks: Promises and Challenges
Abstract
Cloud applications have witnessed significant increase in their development and deployment. This has been driven by the low cost and high performances that can offer cloud paradigm for enterprises to implement innovative services. However, cloud services are constrained by the available transmission rate and the amount of data volume transfers provided by the current networking technologies. Optical networks can play a key role in deploying clouds with enhanced performances, thanks to the high bandwidth and the very low latency provided by optical transmission. Nevertheless, the implementation of optical cloud networks faces many challenges and obstacles, such as the user-driven service nature of cloud applications, resource virtualization, and service abstraction and control. This chapter addresses the design and the implementation of optical cloud networks. Therefore, different issues related to the integration of cloud platform in the optical networking infrastructure are described. Then, current progress achieved to overcome these challenges is presented. Finally, some open issues and research opportunities are discussed.
