Overview
China Telecom Corporation Limited, a state-owned telecommunications provider, operates one of China’s largest content delivery networks, leveraging its extensive infrastructure to optimize content distribution. Founded in 2002, it serves major internet portals and enterprises, including Tencent QQ, Baidu, Sina, and Weibo. The CDN is integrated with China Telecom’s backbone networks, ChinaNet and CN2, to deliver low-latency services across China and globally. It caters to businesses requiring compliance with China’s strict internet regulations, such as ICP licensing, and supports a range of applications from web content to streaming media.
Peer5 operated a peer-to-peer (P2P) content delivery network (CDN) specializing in live video streaming, leveraging WebRTC for in-browser, clientless enterprise CDN (eCDN) solutions. Founded in 2012, the company was acquired by Microsoft in August 2021 to enhance video streaming capabilities in Microsoft Teams. Peer5’s technology optimized bandwidth usage through self-balancing mesh networks, serving large-scale enterprise events with up to 2 million concurrent users. As of 2025, Peer5’s standalone services are defunct, with its technology integrated into Microsoft’s eCDN for Teams.
Network & Architecture
China Telecom CDN operates points of presence (PoPs) across 11 countries, with 15 cities including Sydney, Hong Kong, Tokyo, and Amsterdam. Its domestic strength lies in partnerships with local ISPs like China Unicom and Zenlayer, ensuring robust connectivity within mainland China. The network supports over 1–5 Tbps in traffic capacity, with 788 IP ranges in China alone. Limitations include restricted operations in the U.S. due to FCC orders citing national security concerns, impacting its ability to serve American customers directly. Its global reach is strong in APAC but less comprehensive in EMEA and LATAM compared to providers like Cloudflare or Akamai.

History & Notes
—
Peer5 was known for its innovative use of WebRTC to create a decentralized, browser-based P2P CDN, reducing server load and improving video delivery for large audiences. The company powered events for over 1 billion users before its acquisition. No official EOL announcement for standalone services was found, but Peer5’s website now redirects to Microsoft’s eCDN page, indicating full integration. Some third-party sources mention continued support for existing Peer5 customers post-acquisition, but this is unconfirmed as of 2025.
