Abstract
Enable a CDN server to potentially go forward to any of multiple candidate servers (or other infrastructure) to retrieve a client-requested object, based on periodic testing of such candidate servers or infrastructure for cache hits and network latency (among other things), and scoring thereof. Such candidate servers or infrastructure represent alternative places to get the object. Importantly, a candidate may be a server or infrastructure owned and/or operated by another CDN, including a CDN industry competitor, and may be discovered in a preliminary process that involves detection of multi-CDN arrangements on the Internet where the foregoing approach may be viable.
