Dynamic tag management for optimizing content delivery

摘要

Some embodiments provide a content delivery network (CDN) solution that affords the CDN control over those elements of customer content that are delivered by third parties. The CDN integrates a distributed set of monitoring agents. Each monitoring agent monitors the delivery performance of third parties to the region in which the agent operates. The CDN uses the performance monitoring information to dynamically manage the content tags to the third-party delivered elements of CDN-customer content. Specifically, a CDN server retrieves the parent page for requested CDN-customer content. The CDN server identifies the region from where the request originates and retrieves the logs from the monitoring agents monitoring from that region. The CDN server then modifies the base page by dynamically removing the tags to the third-party delivered elements that are reported in the monitoring agent logs as being unavailable, inaccessible, or underperforming in the identified region.

1. A method for dynamically managing tags to third-party delivered elements of content delivery network (CDN) customer content, the method comprising:
caching a parent page for CDN-customer content, the parent page comprising a set of tags that include a set of elements that are delivered by third-party servers that operate independent of the CDN; receiving at a CDN server, monitoring results measuring the third-party servers' performance in delivering the set of elements to each of a plurality of regions; producing at the CDN server, a first modified version of the parent page for optimized delivery to a first region of the plurality of regions, wherein producing the first modified version of the parent page comprises excluding a first tag from the set of tags that includes a first element that is undeliverable to the first region according to the monitoring results; and passing the first modified version of the parent page from the CDN in response to a request for the CDN-customer content that originates from a user operating in the first region.
