Server initiated multipath content delivery

Abstract:

Described herein are--among other things--systems, methods, and apparatus for accelerating and increasing the reliability of content delivery by serving objects redundantly over multiple paths from multiple servers. In preferred embodiments, the decision to use such multipath delivery is made on the server side. A content server can modify or generate a given web page so as to invoke multipath, e.g., by injecting markup language directives and/or script instructions that will cause the client device to make multiple requests for a given object on the page. Preferably the multiple requests are made to separate content servers in separate points of presence. The teachings hereof may be advantageously implemented, without limitation, in intermediary servers such as caching proxy servers and/or in origin servers.
