摘要
云时代网络DC间带突变,大客户专线要求低时延快开通,传统传输网络已无法适应,面向未来的OTN承载网络必须实现SDN智能化转型。立足于运营商网络现状,提出大型本地网OTN目标架构,结合目标架构的ROADM组网探讨SDN自动规划需求。依据现有OTN网络SDN改造实例,明确现阶段网络实现自动下发功能的传送网SDN架构,提出SDN落地部署建议。
In cloud era,the bandwidth of DC network is changing rapidly. Group customers who want private leased circuit require low delay and fast opening. The traditional transmission network is unable to adapt. The OTN network must realize the intelligent transformation of SDN. Based on the current situation of the operator network,it proposes the target OTN architecture of large local network,and discusses the SDN automatic planning of ROADM network. According to the example of SDN transformation on the existing OTN network,it elaborates the SDN structure of the transport network that realizes the automatic transmission function at the present stage,and puts forward the SDN landing deployment proposal.
