Mobile Streaming Media CDN Enabled by Dynamic SMIL

Category: Software and Web Development, Networking and Communications

Overview This paper presents a mobile streaming media CDN (Content Delivery Network) architecture in which content segmentation, request routing, pre-fetch scheduling, and session handoff are controlled by SMIL (Synchronized Multimedia Integrated Language) modification. In this architecture, mobile clients simply follow modified SMIL files downloaded from a streaming portal server; these modifications enable multimedia content to be delivered to the mobile clients from the best surrogates in the CDN. The key components of this architecture are content segmentation with SMIL modification, on-demand rewriting of URLs in SMIL, pre-fetch scheduling based on timing information derived from SMIL, SMIL updates by SOAP (Simple Object Access Protocol) messaging for session handoffs due to clients mobility.
