摘要
目前,互联网数据中心数据量主要集中在PB/EB级别,在采取虚拟化技术之后,东西流量大幅增加,给传统三层架构带来很大挑战。叶脊架构将网络从三层扁平化为二层,更适于数据中心内部流量的高效运转,帮助企业充分发挥网络的优势,寻求数据中心效用的最大化,提升资源利用率。叶脊架构对整个高端光模块的应用数量是传统架构的数十倍,将强势拉动高端光模块和光器件需求,进一步提升网络容量并降低每比特成本,可有效解决业务流量以及网络带宽持续增长的压力。
At present,the data volume of Internet data center is mainly concentrated in PB/EB level.After the adoption of virtualization technologies,the east-west traffic increases significantly,which brings great challenges to the traditional three-tier architecture.The spine-leaf architecture flattens the network from three layers to two layers,which is more suitable for the efficient operation of internal traffic in the data center.It helps enterprises give full play to the advantages of the network,seek the maximum utility of the data center,and improve the resource utilization.The number of entire high-end optical module applications in spine-leaf architecture is tens of times as great as the traditional architecture,which will strongly drive the demand for highend optical modules and optical devices,further increase network capacity and reduce cost per bit,effectively solve the growing pressure in service traffic and network bandwidth.
