面向数据中心内OpenScale光交换网络的软定义控制平面研究

ompared to traditional datacenter network (DCN) architecture based on electrical switching and tree-form network topology, OpenScale is a novel architecture that uses optical switching technologies to achieve a flat, reconfigurable and bandwidth-elastic network, and has the advantages of high bandwidth, low energy consumption and good scalability. In order to maximize the flexibility of OpenScale network, it is necessary to design an appropriate intelligent control plane, which is capable of effectively coordinating the optical burst switching, wavelength switching and packet switching capabilities. In this paper, considering the specific features of OpenScale, we propose an OpenFlow based control plane solution, including the detailed control mechanisms and OpenFlow protocol extensions. Finally, we setup a simple testbed to verify the feasibility of our proposal.
