英文摘要： Applying optical networking technologies in large scale computing systems has been an irresistible trend which is driven by the IT industry's sustainable development requirements. Optical interconnections used in large scale computing systems typically covers a distance from several centimeters to about one kilometer, which is much shorter than that in the telecommunication scenarios. Therefore, considering the characteristic of data communication in large scale computing systems, this research project investigates the optical interconnection complex network in small space by utilizing complex network analysis theory. Studies are to be carried out around two scientific problems while the main research topics include optical interconnection based complex network topology construction method, new optical network modeling and performance assessment mechanisms, fast routing and load balancing strategies, as well as application-driven on-demand logical topology provisioning scheme. We focus on exploiting the benefits of multi-dimensional resource scheduling capabilities in the optical domain to construct logical topologies with eminent agility. In particular, we creatively propose the idea of building a deterministic small world network with the so called multi-dimensional space folding approach. Based on the proposed network model, we also innovatively depict a corresponding multi-dimension penetration routing scheme and a flow field based load balancing strategy.
