On September 9th, the Global IPv6 Summit was held as scheduled. This conference brought together the world's top industry experts to share industry trends, discuss cutting-edge trends and application deployment, and jointly study IPv6 next-generation Internet technologies and new ecology. New H3C Group, a subsidiary of Tsinghua Unigroup, was invited to attend, and introduced the latest exploration and practice of New H3C in promoting the development of IPv6 next-generation Internet from the perspectives of IPv6 development trends, industry applications, technology implementation and security management.

New H3C proposes six capabilities that IPv6+ large-scale deployment should possess

数字经济已成为中国经济发展的重要引擎，其中下一代网络发展至关重要。2022年初，国务院发布《“十四五”数字经济发展规划》，再次强调要推动IPv6规模部署，助力信息网络基础设施升级。IPv6已经从单纯的互联网技术上升到国家战略层面，随着各种政策的下发，IPv6迎来了全面部署期。除此之外，各种产业的数字化升级也带来了新需求。5G、物联网、高清视频、元宇宙等新业务对网络提出了更高的要求，而算网融合、分支协同、远程办公等新模式的出现同样要求网络能够提供支撑。这些都对网络的灵活敏捷、高效部署、安全可靠提出了更高要求。

IPv6+不是某一个协议或者某一种组网，而是基于IPv6头部的可扩展性衍生出的一系列技术创新和场景创新，作为数智化网络建设的基石，它需要具备以下六大维度的能力：超宽、极简、确定性、融合、智能、可信。因此，新华三集团的IPv6+智能联接方案也由此侧重展开。

技术突破+应用落地+内生安全，新华三助力构建IPv6+智能联接

新华三集团侧重分享了前沿技术探索、行业应用和安全管理这三个方面的实践。

在前沿技术探索方面，新华三重点分享了基于IPv6+技术在确定性广域网的应用与探索。随着智能工厂、远程医疗、无人驾驶等新兴应用的出现，对网络提出了更高的要求。为了满足这些新兴的远程应用环境，在新华三确定性广域网实现中，大量使用了IPv6+的新技术。

● 其一，基于SRv6 TE Policy的严格转发路径约束技术，通过它实现确定性流量的路径独立；

● 其二，借助SRv6+FlexE的多层次切片能力，为确定性应用分配一个独立的平面保障带宽，从而保证确定性流量的较小丢包率；

● 其三，使用基于IPv6的高精度随流检测技术来进行路径链路时延测量与标定，为确定性路径提供纳秒级精度的测量结果，大幅提高了确定性时延的保障效果；

● 其四，在承载协议上选择了可编程的SRv6技术，充分利用SRv6的灵活可编程能力，实现时隙映射信息的携带，保障每一个转发节点都能按照预设的时隙要求传送确定性报文。

In terms of industry applications, New H3C Group adheres to the application-driven concept, takes the business needs of different industries as the basis for technological innovation, and provides subdivided scenario-based solutions. Taking the new-generation SRv6 e-government external network solution as an example, this solution has the characteristics of "one network bearer, cloud-network integration", "network security linkage, active security" and "AI blessing, intelligent operation and maintenance". One of the features is to deploy an SDN backbone network based on SRv6 Policy to realize automatic load balancing and improve link utilization; realize automatic selection of the optimal path according to business requirements, and ensure the quality of key services in real time; realize one-hop access to the cloud, and service opening in minutes . Deploy multiple network slices, integrate multiple private network government applications, and realize the isolation of dedicated slices and exclusive services without interfering with each other. In addition, New H3C actively promotes IPv6 construction in industries such as operators, finance, universities, and large enterprises, and builds a solid foundation for customers in the digital economy era.

In terms of network security, the new IPv6 protocol architecture will also bring technological innovation and system architecture changes in the security field, thereby providing new ideas, new methods and new means for solving network security problems in the IPv6+ era. New H3C builds a network security system suitable for the IPv6+ era based on IPv6+ built-in security attributes and security technology innovations, and proposes a "four-dimensional integration" IPv6+ network endogenous security system, which solves application insight and full-stack visualization from the perception dimension, and analyzes It solves scene cognition and data empowerment from the control dimension, solves precise operation and policy control from the control dimension, and solves independent construction and agile response from the response dimension.

As the core promoter of the development of next-generation network technology, New H3C Group will continue to rely on its forward-looking insight into the IPv6 industry and its full-stack innovation capabilities, and work with industry partners to jointly promote the accelerated development of the IPv6 industry, continuously deepen the application innovation of IPv6 in various industries, and help China's digital economy development.
