智算数据中心光电交换技术综述(特邀)OA北大核心CSTPCD

In recent years,due to the emergence of phenomenal applications of artificial intelligence,the evolution of Artificial Intelligent Data Center(AIDC)and Super Computing Data Center(SCDC)network has become a hot research topic.The tra-ditional three-layer fully connected electrical switching architecture can not well meet the requirement of high bandwidth,low delay,low power consumption and low cost of the AIDC or SCDC,which requires a more efficient and easy expansion way of the electrical and optical fusion switching or optical switching scheme to gradually replace the traditional pure circuit package switching strategy.In this paper,the photoelectric fusion switch technology solutions based on data center in recent years are summarized.The deployment experience of leading Internet enterprises that take the lead in optical switch technology is ana-lyzed.Combined with the needs of the telecom industry,the recommended deployment and evolution strategy of the switch nodes of AIDC and SCDC and super computing center are given.
