On July 14, the Digital Development Forum · Internet Infrastructure Technology Seminar was held at Fuxi Think Tank. Researcher Yao Jiankang from the China Internet Network Information Center delivered a report on “Some Trends in DNS Technology,” with attendees including faculty and students from the Institute of Computing Technology, Chinese Academy of Sciences.

In his report, Researcher Yao provided a detailed overview of several important trends in DNS technology. First, he discussed the development direction of Internet transmission protocols, highlighting QUIC as a competitor to TCP. QUIC improves network efficiency and user experience by reducing handshake times, enhancing congestion control, and boosting security, making it particularly suitable for web application acceleration and real-time communication scenarios. Currently, QUIC traffic accounts for over 50% of total internet traffic and is gradually replacing TCP in some use cases.

Next, he explored the concept of a green Internet, emphasizing the IETF’s efforts in establishing low-carbon and energy-efficient Internet protocol standards while addressing the complexities and challenges in implementing DNS protocols. He also discussed the trend toward decentralization in the Internet, mentioning protocols like DoH and DoT that reduce centralization and introducing the SOLID framework proposed by Tim Berners-Lee. This framework offers a new data management solution by allowing personal storage management of data.

In terms of security, he highlighted the large-scale deployment of TLS 1.3 and the gradual strengthening of encryption technologies, such as TLS Encrypted Client Hello, which provide higher security for Internet communications. Additionally, automated DNSSEC deployment through CDS and CDNSKEY records has simplified key management, further enhancing security and management efficiency. Overall, DNS technology is advancing toward greater efficiency, security, and environmental sustainability.

During the post-seminar discussion, participants explored issues related to the popularization of new DNS technologies and future engineering development directions.

The Internet Infrastructure Technology Seminar was organized by the Internet Infrastructure Technology Laboratory of the Institute of Computing Technology, Chinese Academy of Sciences, and the Digital Transformation Laboratory of Fuxi Think Tank. It is an integral part of the industry’s “Digital Development Forum,” focusing on key technologies in Internet infrastructure.
