Abstract: A system for steering chunked media content using a plurality of content delivery networks (CDNs) and an edge computing platform, is disclosed. Upon receiving a media content request, a first edge server routes the request to a first CDN for delivering chunks of media content. A second edge server processes a steering request to instantiate a stateless steering server. The second edge server analyzes Quality of Service (QOS) of the CDNs to determine a priority order of the CDNs for future content delivery. The steering server generates a response containing a priority order of CDNs, a time interval for subsequent requests, and a reload URI. The URI triggers a new steering server instantiation with the plurality of CDNs after the time interval. The system enhances media playback by dynamically steering content across CDNs based on QOS analysis.
