End-to-end Acceleration Of Dynamic Content

A method of accelerating dynamic content between Points of Presence (POPs) and front-loading latency bottlenecks in a Content Delivery Network (CDN) may include receiving, at a first POP, a content request from a user device, where content responsive to the content request includes a first content portion that is not stored in the first POP. The method may also include determining that the first content portion is available through a second POP. The method may additionally include transmitting the first content portion through a persistent connection mesh from the second POP to the first POP, wherein the persistent connection mesh is maintained between the first POP and the second POP prior to the request for content being received by the first POP. The method may further include delivering the content responsive to the content request to the user device.

1 Independent Claims

  • Claim CLM-00001. 1. (canceled)
  • Claim CLM-00002. 2. A system for accelerating content between Points of Presence (POPs) in a Content Delivery Network (CDN), comprising: a first POP in the CDN, the first POP comprising a first plurality of edge servers that store and distribute content in response to user requests; a second POP in the CDN, the second POP comprising a second plurality of edge servers that store and distribute content in response to user requests and; and a persistent connection mesh between the first POP and the second POP; wherein: content responsive to a content request received at the first POP comprises a first content portion that is not stored in the first POP; the first content portion is available through the second POP; and the persistent connection mesh is maintained between the first POP and the second POP prior to the content request being received by the first POP.
  • Claim CLM-00009. 9. A system for accelerating uncached content between Points of Presence (POPS) in a Content Delivery Network (CDN), the system comprising: a first POP comprising a first plurality of edge servers in the CDN; a second POP comprising a second plurality of edge servers in the CDN; and a connection between the first POP and the second POP, wherein: the first POP receives a content request from a user device; the connection is available between the first POP and the second POP prior to the content request being received by the first POP; and the connection is pre-warmed to increase the congestion window.
  • Claim CLM-00016. 16. A Content Delivery Network (CDN) for accelerating content, comprising: an origin server communicating with a plurality of origin addresses; and a Point of Presence (POP) maintaining a connection with the origin server, the POP comprising a plurality of edge servers; wherein the connection is pre-warmed to maximize a throughput of the connection, and wherein the POP is configured to receive a content request from a user device while the connection is maintained with at least a portion of the content request resulting in a cache miss, and
