摘要
对构建下一代灵活数据中心互连网络的问题,提出了结合不同维度光交换技术的光电混合互连网络搭建思路,使未来数据中心网络具备动态拓扑重构、灵活带宽调整等特性,可以有效应对数据中心发展中由于硬件重构、业务多样等趋势导致的业务突发性强、通信模式差异大等问题。同时,在光电混合互连网络的构建与实用化过程中,仍需在智能控制体系架构、高速突发接收、低延时与低抖动控制等方面取得突破。
In this paper,a hybrid optical and electrical interconnection network with multidimension of optical switching technologies is proposed for the construction of next generation flexible data center interconnection network.The future data center network(DCN)has the characteristics of dynamic topology reconfiguration and flexible bandwidth adjustment which can effectively deal with the problems such as traffic burstness and various communication pattern due to hardware disaggregation and service diversification.At the same time,there are still lots of technique bottlenecks that need to be broken,including intelligent network control system,high speed optical burst receiver and low latency and low jitter network control system in the approach of building the optical/electrical hybrid interconnection network.
