Core Insights - The report titled "China Unicom's Computing and Network Integration CDN Technology Research White Paper (2025)" focuses on the development and application of CDN technology under the trend of computing and network integration, addressing the bandwidth and low-latency demands of emerging video applications such as ultra-high-definition 3D live streaming, XR, and cloud gaming [1][12]. Group 1: Research Background - "Internet 2030" outlines six key features, including full interconnectivity and computing-network integration, emphasizing the need to break down barriers between computing, data, and networks [1][17]. - CDN has evolved through three stages: traditional transmission, content distribution, and integration with network operations, necessitating collaboration with underlying networks for effective computing-network integration [1][22]. - As of May 2024, there are 794 million active IPv6 users in China, with 96.14% of typical CDN companies having completed IPv6 node upgrades, laying a foundation for CDN advancements [1][26][28]. Group 2: China Unicom CDN - Cloud Universe Technology Co., Ltd., a joint venture between China Unicom and Tencent, focuses on CDN and edge computing, supporting the construction and development of China Unicom's CDN network [1][32]. - China Unicom's CDN network has been established nationwide, serving top domestic internet companies and mobile manufacturers, with plans to expand to cover all prefecture-level cities within three years [1][35]. - The development of China Unicom's intelligent CDN is planned in three phases: 1.0 focuses on traditional content distribution, 2.0 leverages MEC and BNC for low-latency video services, and 3.0 aims to integrate AI edge inference with CDN and MEC for real-time content distribution [1][38]. Group 3: Key Technologies in Computing-Network Integration CDN - SRv6 routing optimization reduces dynamic acceleration latency by 20%-30% by slicing forwarding paths and constructing low-latency acceleration channels [1][25]. - Application-aware CDN utilizes APN technology to deeply integrate business distribution and network scheduling, addressing the traditional disconnect between CDN and networks [1][24]. - Unified transport protocols focus on QUIC and MoQ, providing standards for AIGC content distribution, supporting low latency and publish/subscribe models [1][29].
