Overview
CDNetworks, founded in 2000, is a global content delivery network (CDN) provider offering services for web performance, media delivery, and cloud security. Headquartered in Singapore, it serves industries like e-commerce, gaming, and media, with clients including Alibaba, Samsung, and Hyundai. Its CDN Pro (formerly CDN360) focuses on delivering static and dynamic content with enhanced security features. The company emphasizes strong network presence in Asia, particularly China, and provides solutions like DDoS protection and edge computing. CDNetworks is owned by Wangsu Science & Technology since 2017.
Comcast operates a content delivery network (CDN) focused on delivering video streaming and low-latency content for ISPs and content providers. As a major U.S. telecommunications provider, Comcast leverages its extensive network infrastructure to support high-quality live sports streaming and video-on-demand services. The CDN, enhanced by partnerships like Qwilt, serves content providers seeking reliable delivery within Comcast’s broadband footprint. It primarily caters to enterprise clients, including those requiring high-bitrate streaming for events like the Paris Olympics in 2024. Comcast’s CDN is integrated with its broader connectivity services, targeting users within its 63 million U.S. locations.
Network & Architecture
CDNetworks operates over 2,800 Points of Presence (PoPs) across six continents, with a strong focus on the Asia-Pacific region, including China and India. Its network leverages global peering and an anycast architecture to optimize routing and reduce latency. The company holds an ICP Beian license, enabling compliant content delivery in Mainland China. Regional strengths include extensive coverage in APAC, but its North American and African footprints are less dense compared to competitors like Akamai or Cloudflare.
Comcast’s CDN operates across its U.S. network, covering 63 million locations, with points of presence (PoPs) optimized for North America. The network uses Qwilt’s Open Edge platform for content caching and delivery, built on Open Caching specifications from the Streaming Video Technology Alliance. It supports high-quality streaming, including 4K UHD, with a focus on live sports and video-on-demand. Routing benefits from Comcast’s backbone infrastructure, but its regional focus limits global coverage. Peering with major ISPs enhances performance in the U.S., though competition from fixed wireless providers like Verizon and T-Mobile impacts its broadband market share.

Integrations & DevEx
CDNetworks supports Terraform for infrastructure-as-code, with OpenAPI Explorer for API integration. Its CDN Pro Portal and API provide access to real-time logs and analytics, facilitating monitoring and optimization. SDKs are not extensively documented, but the API-first design supports custom integrations. Migration tools are not explicitly mentioned, though the console supports cloning configurations for easier setup. CI/CD integration is possible via APIs but lacks native plugins for common pipelines.
