摘　　要：确定性网络相比传统IP网络的“尽力而为”服务提供确定性服务质量保证,满足日益增长差异化的IP业务承载要求。在以太网局域和IP限制域网络,IEEE和IETF国际标准组织分别成立了时间敏感网络和确定性网络工作组,并发布了系列标准。目前,产业界已经开展面向大规模确定性网络的研究,已经有共识需要对确定性网络技术进行必要的增强,发展新的增强确定性网络架构。在IETF确定性网络架构基础上提出了一种三维增强确定性网络架构,并基于该架构研制的原型样机进行了测试验证,验证结果显示,该架构满足大规模确定性网络的需求并具备很好的兼容性。Comparison to the traditional“best-effort”QoS of IP-based network,deterministic networking had pro-vided guaranteed QoS capabilities catering the requirements of differentiated increasing IP-based services.In the lo-cal Ethernet network and limited domain IP network,IEEE and IETF had approved the time-sensitive networking and deterministic working groups,which had published series standards.At present,the large-scale deterministic net-working research has been carried out in the industry.There has being a consensus that the deterministic networking technology needs to be enhanced,and a new enhanced deterministic networking architecture needs to be developed.A three-dimension enhanced networking architecture was proposed,and the prototype devices verification based the architecture were provided.The results of verification show that it can meet the large-scale deterministic requirements with the well compatibilites for existed IP network.
