摘要
近年来，由于人工智能现象级应用的出现，智算数据中心（AIDC）和超算数据中心（SCDC）网络演进成为研究热点。传统的3层全连接电交换架构已经不能很好地满足AIDC或SCDC高带宽、低时延、低功耗和低成本的需求，需要一种更为高效和易于扩容的电光融合交换或光交换方案来逐步替代传统纯电路包交换的策略。文章对近年来基于数据中心的光电融合交换技术方案进行了综述性介绍，对行业中率先进行光交换技术尝试的头部互联网企业的部署经验进行了分析，并结合电信行业需求，给出了AIDC和SCDC交换节点的推荐部署和演进方式。
Abstract
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 traditional 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 analyzed. 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.
