Abstract
A method of content delivery in a content delivery network (CDN), where the CDN is deployed, operated and managed by a content delivery network service provider (CDNSP). The CDN comprises a set of content servers and a domain name system (DNS) associated with a CDN namespace. For a given content provider, a determination is first made whether the content provider has “cold content” delivery requirements by evaluating one or more factors that include: total content size, size of content objects expected to be served, uniqueness of content, total number of content objects, and a percentage of the total content size that is expected to account for a given percentage of traffic. Upon a determination that the content provider has cold content delivery requirements, a subset of the CDN content servers are configured to implement a set of one or handling rules for managing delivery of the cold content from the CDN content servers.
