英文摘要: As an important carrier providing the capacity of information storing and processing, data center is the core infrastructure to support the development of information industry in our country. With the rapid increase of network users and emergence of new network business, traditional intra-data center networks (DCNs) based on electrical interconnection are met with technical bottlenecks inevitably in terms of throughput, energy efficiency and flexibility. Due to the advantages of larger capacity, higher energy efficiency and higher flexibility, optical space-division multiplexing (SDM) confirms well with the demand of future data center network, and thus it is hopeful to be used to break through the bottlenecks of large-scale intra-DCNs. In this context, we propose the all-optical interconnection intra-DCN based on SDM and focus on the investigation of several relative issues, such as the design of network topology and node structure, the mode control mechanism adapted to the intra-DCNs characteristics, and the strategy of global service response and resource scheduling with the Utility-based scheme. The research mentioned above will provide important theoretical and technical references for the development and application of future DCNs.
