A Green and High Efficient Architecture for Ground Information Port with SDN

The ground information port composed of distributed cloud data centers with interconnection is the core for spatio-temporal data access, processing and distribution in the space-ground integrated information network and can provide large-scale computation, storage and network forwarding resources. Thus, the performance improvement of the ground information port not only faces the traditional resource scheduling and task allocation problems, as the scale of business grows, its power consumption also explodes, which has become a bottleneck restricting the sustainable development of the ground information port. By introducing Software-Defined Networking (SDN) into the ground information port, this paper proposed an overall SDN-based green and efficient architecture for the ground information port. The SDN controller unifying scheduling and allocation of the whole network resources can not only maintain the efficient operation of the ground information port, but also effectively reduce the power consumption. This paper provides a feasible solution to solve the pain points in the industry.
