On August 23, the 7th Future Network Development Conference, which has attracted much attention from the industry, kicked off in Nanjing. Academicians of the two academies, experts, scholars, and business representatives gathered in Jinling to discuss cutting-edge network technology trends and research results of special projects. New H3C Group, a subsidiary of Tsinghua Unigroup, was invited to participate in this grand event. At the "Future Network Helps East and West Computing Forum", Zeng Fugui, Vice President of New H3C Group and President of Network Product Line, delivered a keynote speech on "Building a Computing Power Network Technology Base with IPv6" , shared H3C's computing power network architecture based on IPv6+ technology and the latest practical progress, using high-quality network connections to lay a solid digital foundation for technological innovation in various industries in the AI ​​​​era.

Explosive demand for computing power is the key to efficient coordination and linkage of computing networks

Currently, the AIGC upsurge represented by large models has brought about explosive growth in demand for computing power. According to data, the average growth rate of computing power in China has reached 30% in the past five years. Zeng Fugui pointed out that in order to increase the supply of computing power, in addition to improving the performance of computing equipment itself, the transmission level is also important. In this regard, he put forward two technical ideas: one is to improve the computing power level of the data center by improving chip technology and network transmission efficiency; the other is to use cross-regional computing power network construction to promote efficient complementary computing power and collaborative linkage. In this way, the efficiency of each link in the supply of computing power resources can be realized more comprehensively.

At the level of computing power cross-domain transmission, the network has transformed from a simple connection foundation and computing power access foundation to the main carrier for building ubiquitous computing power. Compared with the traditional network, the computing power network has the characteristics of scattered resources, mixed bearing, and blurred boundaries. As a result, the wide area network that carries the computing power network business needs to have the three major capabilities of identifying computing power applications, network resource allocation, and dynamic boundary security. This is exactly the research and development direction that IPv6+ technology focuses on.

Three key technologies support IPv6+ foundation computing power network base

IPv6+ is the direction of Internet upgrading and evolution. It has gone through three stages of development: protocol simplification and network programmability in the 1.0 stage, experience assurance and partial network autonomy in the 2.0 stage, and application awareness and high network autonomy in the 3.0 stage. Zeng Fugui pointed out that IPv6+2.0 is currently in the stage of moving towards 3.0. As the first enterprise in the world to pass the "IPv6+ Ready 2.0 & SRv6 Ready" test and certification established by China Academy of Information and Communications Technology Taier Laboratory, H3C Group relies on APN6 and network slicing. The application of key technologies such as SRv6 SFC and SRv6 realizes cross-domain computing power transmission and provides sufficient technical reserves for the construction of computing power networks.

●Recognition of computing power applications based on APN6: H3C uses APN6 and edge computing to identify and identify application types, distinguish computing power applications from common applications through the application information carried in traffic, and select different processing strategies according to application requirements. Based on this, for computing-intensive applications, priority and stable resource guarantees can be provided to ensure their efficient and smooth operation.

Realize network resource allocation based on multi-level slicing: adopt multi-level slicing technology solutions, combine sub-interfaces, SRv6 and FlexE, reduce the slicing granularity from Gb level to Mb level, and support thousands of slices in a single network , realize that the computing power network provides flexible slicing options for customers of different levels and different industries on demand, provides independent network resource guarantee for computing power applications, and ensures computing power application experience.

●Realize dynamic boundary protection based on SRv6 SFC: To meet the needs of users applying for computing power applications, H3C provides corresponding security resources and SFC policies, and establishes an on-demand protection boundary with dynamic policies and resource allocation mechanisms, which enhances the adaptability of the network and response speed, strengthen the border security of the computing power network, and reduce the comprehensive operating cost of the computing power network.

At present, based on the computing network brain and IPv6+ technology, H3C has conducted practical verification for different application scenarios of the computing power network. In the research practice of the VDI platform based on the computing power network, H3C uses the computing network brain, cloud management platform and VDI management platform to dynamically allocate and adjust the corresponding cloud platform resources and network resources according to the resource application requirements of the VDI client side, so that Customers have obtained high-quality VDI application experience.

Establishing standards and emphasizing practice to promote computing power network to industrial implementation

The deep integration of artificial intelligence scenarios and all kinds of industries is urging the computing power network to move towards industrial implementation. Zeng Fugui said, "The computing power network spans multiple regions and integrates different technical fields such as intelligent computing, storage, and networking. Therefore, unified standards are the prerequisite for orderly construction. It is necessary to establish system architecture standards and computing power evaluation systems as soon as possible. Standards, software and hardware interface standards, etc.

Over the years, New H3C Group has actively participated in the standard work of authoritative organizations at home and abroad such as IETF and CCSA, and has participated in the formulation of relevant standards in SRv6, slicing, iFIT, SRv6 SFC, APN6, and computing power networks. In terms of key computing power network technologies, H3C submitted three standard drafts related to APN6 technology at this year's IETF meeting; on the basis of product research and development, the IETF is promoting the draft standards related to network slicing, among which SliceID related standards have been obtained Industry recognition and application landing. Faced with the diversification of industry application scenarios, H3C has become a key force in the formulation and promotion of standards in the ICT field.

Accelerating the construction of a computing power network is a major measure to implement the national strategy of "computing from the east to the west" and realize the digital intelligence upgrade of all industries. Looking forward to the future, under the guidance of the "cloud intelligence native" strategy, H3C Group will adhere to the concept of "intensive cultivation and pragmatism, and give wisdom to the times", and join hands with industry partners to continuously improve network quality and create a more solid platform for industry-wide application innovation. Connect the base.
