Abstract
Systems and methods of operating a content node that caches digital content for end users are provided herein. The content node is configured to cache data. When the content node receives a request for content that is not presently cached, the content node identifies the origin server associated with the requested content. The content node monitors network characteristics for at least the origin server and one or more service providers that transfer content between the origin server and the content node. The content node selects a network address associated with a particular service provider based upon network characteristics and requests the origin server to deliver requested content and the selected address.
