摘要
由于互联网业务的快速发展,数据中心的流量已经占据全球通信网络流量绝大部分。作为高速信息传输的主要载体,如今光通信技术已经在数据中心中得到了广泛应用,从距离几米服务器间的光互连到连接世界各地数据中心的光网络。概要介绍了数据中心的光通信技术,包括数据中心之间互连的广域网、城域网技术和数据中心内部服务器及交换机之间光互连技术,并对各个领域内一些不同的技术方案做了简要的讨论和比较。
Due to the fast growth of internet services, datacenter related traffic has become the major part of the global network traffic. As a main technology for high-speed data transmission, optical communication technologies have been widely used in today＇s datacenter networks, from a few meter server-to-server interconnects to transoceanic datacenter-to-datacenter optical networks. Here the optical communication technologies for datacenters were reviewed, including technologies connecting datacenters in wider-area networks and metro-area networks as well as optical interconnect technologies within datacenters, and the advantages and disadvantages of some technologies in the networks were discussed.
