On August 23, the Seventh Future Network Development Conference, which attracted much attention from the industry, kicked off in Nanjing. Academicians, experts, scholars and enterprise representatives of the two academies gathered in Jinling to talk about the trend of cutting-edge network technology and the research results of special topics. Zeng Fugui, vice president of Xinhua Group and president of network product line, delivered a keynote speech on "constructing computing network technology base with IPv6", sharing Xinhua three's computing network architecture and latest practice progress based on IPv6 + technology, and tamping digital base for technological innovation of various industries in AI era with high-quality network connection.

Efficient coordination of computing network is the key to the outbreak of computing demand.

At present, the AIGC craze represented by big models has brought about an explosive growth in the demand for numeracy. Data show that the average growth rate of numeracy in China has reached 30 per cent in the past five years. Zeng Fugui pointed out that in order to improve the supply of computing power, in addition to improving the performance of the computing equipment itself, the transmission level is also important. For this, he puts forward two technical ideas: one is to improve the computing power level of the data center by improving the chip technology and improving the network transmission efficiency; the other is to make use of the cross-regional computing network construction to promote the efficient complementarity and coordination of computing power. In this way, the efficiency of each link of the supply of computing resources can be improved in a more comprehensive way.

At the level of computing cross-domain transmission, the network has changed from the simple connection basis and computing access basis to the main carrier of ubiquitous computing power. Compared with the traditional network, the computing network has the characteristics of scattered resources, mixed bearing and fuzzy boundary, which leads to the need for the wide area network carrying computing network services to have three capabilities: identifying computing applications, network resource allocation and dynamic boundary security, which is the research and development direction of IPv6 + technology.

Three key technologies support IPv6 + Foundation Computing Network Base

IPv6 + is the direction of Internet upgrade and evolution, which has experienced three development processes: protocol simplification and network programmability in stage 1.0, experience guarantee and partial autonomy in stage 2.0, application awareness and a high degree of autonomy in stage 3.0. Zeng Fugui pointed out that at present, IPv6+2.0 is moving towards 3.0. as the first company in the world to pass the test and certification of "IPv6+ Ready 2.0 & SRv6 Ready" developed by Tyre Laboratory of China Information and Communication Institute, Xinhua Group has realized cross-domain computing power transmission with the application of key technologies such as APN6, network slicing and SRv6 SFC, providing sufficient technical reserves for the construction of computing network.

● realizes the identification of computing applications based on APN6: Xinhua three uses APN6 and edge computing to identify and identify application types, distinguishes computing applications from ordinary applications through the application information carried in the traffic, and chooses different processing strategies according to application requirements. Based on this, for computing-intensive applications, it can provide priority and stable resource guarantee to ensure its efficient and smooth operation.

● implements network resource allocation based on multi-level slicing: a multi-level slicing technology scheme is adopted, which combines subinterfaces, SRv6 and FlexE to reduce the slicing granularity from Gb to Mb, and can support thousands of slices in a single network, so that the computing network can provide flexible slicing options for customers of different levels and industries on demand, provide independent network resource guarantee for computing applications, and ensure the experience of computing applications.

● implements dynamic boundary protection based on SRv6 SFC: to meet the needs of users applying for computing applications, Xinhua 3 provides corresponding security resources and SFC strategy, establishes on-demand protection boundaries with dynamic policies and resource allocation mechanisms, enhances the adaptability and response speed of the network, strengthens the boundary security of computing networks, and reduces the comprehensive operating costs of computing networks.

At present, Xinhua San has carried out practical verification for different application scenarios of computing network based on computing network brain and IPv6 + technology. In the research and practice of VDI platform based on computing network, Xinhua San 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 needs of VDI clients, so that customers can obtain high-quality VDI application experience.

Establishing Standards and emphasizing practice to promote Computing Network to Industrial Landing

The deep integration of artificial intelligence scene and all kinds of industries is driving the computing network to the industrial landing. Zeng Fugui said, "the computing network spans many regions and integrates many different technical fields, such as smart computing, storage, network, and so on, so a unified standard is a prerequisite for orderly construction. It is necessary to establish system architecture standards, computing evaluation standards, software and hardware interface standards, and so on as soon as possible."

Over the years, Xinhua Group has actively participated in the standards work of domestic and foreign authoritative organizations such as IETF and CCSA, and has participated in the formulation of relevant standards in SRv6, slicing, iFIT, SRv6 SFC, APN6, computing network and so on. In terms of key technologies of computing network, Xinhua San submitted three draft standards on APN6 technology at this year's IETF conference; on the basis of product research and development, it is promoting the draft standards related to network slicing in IETF, among which the relevant standards of SliceID have been recognized and applied in the industry. In the face of the diversification of industry application scenarios, Xinhua 3 has become a key force in the formulation and promotion of standards in the field of ICT.

Speeding up the construction of the computing network is a major measure to implement the national strategy of "counting the east and counting the west" and to realize the intelligent upgrading of a hundred banks and industries. Looking to the future, Xinhua three groups will take the "Yunzhi original" strategy as the guidance, uphold the concept of "intensive cultivation and pragmatism, and endow the times with wisdom", and work with industry partners to continuously improve the network quality. to create a more solid connection base for industry-wide application and innovation.
