Content delivery network transitional caching

A communication network comprising:

• a plurality of edge cache nodes, each edge cache node configured to:
• receive a first request for content from an end user;
• and
• provide the content to the end user in response to the first request;
• a transitional cache node array configured to:
• function as a virtual origin to one or more of the plurality of edge cache nodes, comprising:
• receiving storage content from an origin server;
• pre-processing the storage content into pre-processed storage content;
• storing the pre-processed storage content in a memory;
• receiving an origin content request from at least one of the plurality of edge cache nodes, the origin content request corresponding to the first request for content, and the content corresponding to the pre-processed storage content;
• responding to the origin content request by sending the pre-processed storage content to one or more of the plurality of edge cache nodes.

A method of operating a transitional cache node array, the method comprising:

• receiving storage content from an origin server;
• pre-processing the storage content into pre-processed storage content;
• storing the pre-processed storage content in a memory;
• receiving an origin content request from at least one of a plurality of edge cache nodes, wherein each of the plurality of edge cache nodes is configured to:
• receive a first request for content from an end user, wherein the first request for content corresponds to the origin content request;
• provide the content to the end user in response to the first request, wherein the content corresponds to the pre-processed storage content;
• responding to the origin content request by sending the pre-processed storage content to one or more of the plurality of edge cache nodes.
