Overview
Cedexis was a MultiCDN platform specializing in real-time traffic steering and performance monitoring, optimizing web and cloud application delivery across multiple CDNs and data centers. Founded in 2009 by Julien Coulon and Marty Kagan, it was acquired by Citrix in 2018 and integrated into its Intelligent Traffic Management (ITM) product. The platform was used by enterprises, including media outlets like L’Equipe, Le Figaro, and Le Monde, to enhance global web performance. Cedexis is now defunct, with its ITM product reaching end-of-life (EOL) in October 2025.
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
—
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.

History & Notes
Cedexis was known for its Radar, Fusion, Sonar, and OpenMix tools, which provided real-time visibility and programmable traffic management across CDNs and clouds. Its acquisition by Citrix aimed to bolster hybrid and multi-cloud performance but faced challenges, including a notable DDoS attack in May 2017 impacting French media clients. The decision to sunset ITM reflects Citrix’s strategic shift, with no reported plans for a direct successor. NS1 Connect has emerged as a key alternative, leveraging similar DNS-based steering technology.
