With the increasing acceleration requirements of the Internet, complex network environments and diverse video services, experts in the field of audio and video technology are constantly exploring how to achieve accurate and extremely low-latency network transmission capabilities. They actively work on application layer flow control, transport layer protocol design and cross-layer optimization to improve users' network experience.
In today's digital age, network performance is critical for critical applications in various industries. Whether it is online gaming, high-definition video streaming, real-time audio and video communication, or IoT devices, efficient network transmission is required to ensure fast and reliable transmission of data. Technicians are actively researching and developing new network technologies and algorithms to improve network performance and stability. They focus on application layer flow control to ensure that different types of data have sufficient bandwidth on the network, and innovate in transport layer protocol design to reduce latency and packet loss. In addition, cross-layer optimization methods are constantly evolving to provide more integrated network solutions.
In this technical conference, we will discuss network optimization practices in depth and share the latest technological progress and best practices. We will learn how to jointly optimize RTC cloud and network to cope with growing network demands, how to optimize weak network countermeasures to cope with complex network environments, and listen to the capabilities and practices of the QUIC protocol. Through the practice of network optimization, we will jointly explore the future of network transmission capabilities and create a better network experience for users.
01
Explore the technical operation practice of QUIC-Wangsu CDN
Zhuang Xiaochuan
Wangsu Technology Streaming Media R&D Manager
Streaming media application scenarios are becoming increasingly diverse, and the TCP protocol performs poorly in weak network scenarios. QUIC, with its low latency and flexible transmission algorithm, is suitable for video transmission in various network environments, but it also brings a better user experience. , the application prospects of the QUIC protocol also face many challenges.
This sharing will be divided into three parts. The first part introduces QUIC’s technical advantages and challenges; the second part introduces Wangsu QUIC’s technology selection and basic capability solutions, and how it is applicable to various CDN business scenarios; This part introduces the operational practices of Wangsu QUIC, focusing on QUIC business monitoring and service governance, and how to support large-scale QUIC service levels.
Through the above three parts, we will systematically introduce to you the basic capabilities of Wangsu in the QUIC protocol and its large-scale service operation and construction experience.

Jingdong real-time audio and video weak network confrontation practice
Li Qingbo
JD real-time audio and video JRTC technical leader
In the field of real-time audio and video, we hope to give users a better quality of experience, allowing users to enjoy real-time smooth services and clear audio and video content. However, the scale of Internet users is huge, the networks they are on are complex and diverse, and the quality is uneven. Solving the contradiction between experience quality and network quality is a major challenge facing real-time audio and video, which requires powerful weak network countermeasures technology.
This sharing will be divided into three parts. The first part introduces common strategies and key technologies for real-time audio and video weak network confrontation. The second part introduces JD.com’s real-time audio and video practice and exploration in weak network confrontation. The third part shares JD.com’s real-time audio and video countermeasures. Representative implementation cases of audio and video.

The practice of joint optimization of Yuanxiang RTC cloud network terminal and three terminals
Tu Chengjie
Founding technology partner of Yuanxiang
Low-cost and rapid development and customization based on WEB are important business models of Yuanxiang. H5 and small programs are the main communication methods of Yuanxiang's applications. With the rapid development of business, the initial WebRTC-based Yuanxiang RTC implementation is increasingly unable to meet the increasingly higher requirements for latency/stuttering/compatibility.
This sharing first analyzes the many limitations and drawbacks of WebRTC-based implementation, and then introduces how Yuanxiang uses self-developed technology to gradually get rid of its dependence on WebRTC in cloud encoding and streaming/network transmission/end-to-end streaming and decoding. Finally, it focuses on the cloud network The joint optimization of end-to-end and three-end integration results in a much lower cost and better experience than the implementation based on WebRTC.
