Abstract
Distributed content caching is implemented in an efficient, low cost manner within a content delivery network (CDN). In various embodiments, content is identified for caching at a number of gateway devices within a CDN by minimizing a cost function associated with content delivery in the network. The cost function may take into consideration costs of delivering content to users from gateway devices as well as costs associated with delivering content to users from centralized locations of a CDN.
