Optimizing content delivery over a protocol that enables request multiplexing and flow control

摘要

A content delivery network (CDN) proxy (or, more generally, a server) that is content-aware is programmed to modify or augment a content object in such a manner that the content object, or elements thereof, is or are deliverable to a requesting client over a multi-stream, priority-enable connection. A representative application layer protocol that implements such delivery is SPDY. By virtue of its content-awareness, one or more elements of the content object may be delivered with prioritization so as to optimize “effective” page load time, namely, the time necessary for usable portions of the page to be loaded and rendered on the requesting client.
