英文摘要： Extremely large scale Data Center is the most important infrastructure for the cloud service. Focusing on the major challenges of the intra-datacenter networks, this project aims to investigate the fundamental theories and technologies on related topics, which meets the critical demands of China’s next generation green information technology deployment and industry development. The project is supposed to solve three key scientific problems, namely, the architecture of the exascale full-bandwidth all-optical switching network with dynamically arbitrarily-scaleable capability; the novel transmission control schemes of highly dynamic data communication with high reliability and controllable latency performance; the cross-layer-optimized control mechanism for multidimensional-networks with high resource and energy efficiency. Listed below are the specific research contents: data exchange model of datacenters for cloud computing; all-optical switching network architecture designing; elastic transmission technology of highly dynamic data communication; application-oriented latency controllable; highly reliable self-adaptive protocol stack; software-defined cross-layer control theory, etc. This project innovatively proposes the OpenScale network architecture of intra-datacenter networks and related theoretical analysis, as well as the ultra-lightweight, high-speed, high-efficiency transmission protocols based on dynamic network environment perception, etc. The project is expected to take some breakthroughs in fundamental theories and technologies on related topics, and implement a prototype of the full-bandwidth all-optical switching network with dynamically arbitrarily-scaleable capability, which is able to support a cloud datacenter with more than 200,000 servers.
