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。

关键词: 增强确定性网络, 增强确定性网络架构, 增强确定性网络验证

Abstract:

Comparison to the traditional “best-effort” QoS of IP-based network, deterministic networking had provided guaranteed QoS capabilities catering the requirements of differentiated increasing IP-based services.In the local 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 networking 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.

Key words: enhanced deterministic networking, architecture of enhanced deterministic networking, verification of enhanced deterministic networking
