摘　　要：随着产业数字化转型深入推进,IPv6应用和确定性网络传输需求倍增。在IPv6+技术与确定性网络融合应用基础上,提出了一种基于IPv6+的城域云网对接IPv6根服务器的确定性网络应用架构设计以及测试方法,采用SRv6 over EVPN、OLT双归上联、跨设备聚合、v BRAS池热备用机制和IPv6根服务器镜像下沉等关键技术,实现在实际城域云网环境下确定性时延、抖动、丢包、IPv6 DNS解析、热切换等高可用关键指标满足确定性网络需求及行业专线场景应用需求,并展望基于控制器SRv6 TE模式下APN6的新型城域云网确定性网络现网传输与行业应用演进方向。With the in-depth advancement of industrial digital transformation,the demand for IPv6 and deterministic networking has doubled.Researches the integration of IPv6+and deterministic networking technology,application architecture and testing method for IPv6+-based metropolitan cloud network deterministic networking.The proposed application architecture applies a series of key technologies,which include SRv6 over EVPN,OLT dual-homing uplink,cross-device aggregation,vBRAS pool hot standby mechanism and IPv6 root server mirror sinking technology,in order to achieve deterministic high-availability indicators in the actual metro cloud network environment,such as deterministic latency,jitter,packet loss,IPv6 DNS resolution,and hot switching,meeting the requirements of deterministic networking and industrial private line pplication.Furthermore,this paper looks forward to the deployment of the SRv6-TE-mode-based APN6 new metro cloud network deterministic networking for the current network,and the evolution direction of the industrial application.
