HTTP-based Adaptive Streaming (HAS) has become a widely-used video delivery technology. Use of HTTP enables relatively easy firewall/NAT traversal and content caching. While caching is an important aspect of HAS, there is not much public research on the performance impact proxies and their policies have on HAS. In this paper, the authors build an experimental framework using open source Squid proxies and the most recent Open Source Media Framework (OSMF). A range of content aware policies can be implemented in the proxies and tested, while the player software can be instrumented to measure performance as seen at the client.
