Abstract: 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.

Abstract: Methods, systems and computer program products for delivering content objects over the Internet are disclosed. Use of a packet size digest allows for look-up of known or discovered maximum packet sizes for network paths to various receiving systems by servers within one or more points of presence of a content delivery network, such that the packet size information can be advantageously re-used by the multiple servers to reduce delays associated with lost packets and time spent determining a path maximum packet size or maximum transmission unit by each of the multiple servers within the point of presence as they transmit content objects over the Internet.

Abstract: A system and method for accelerating web page delivery is disclosed in one embodiment. Web content requests are made to an edge server of a first point of presence (POP) of a content delivery network (CDN). The web content has embedded resource links. The first POP can rewrite the embedded resource links to route requests for the embedded resource links to any POP in the CDN or even the origin server. In some embodiments, the first POP can decide if the first POP and/or another POP referenced in a rewritten embedded resource link should cache and/or accelerate the resource referenced in the embedded resource link.

Abstract: A system may be provided for dynamically serving a content file with embedded content objects over the Internet to an end user system. A content object request function may receive a request for a webpage defined by the content file, the content file comprising embedded content objects. A content-file modifier may modify the content file to inject a reporting code that instructions to generate one or more reports comprising information relating to the content objects. A report receiver may receive the reports, the reports indicating where the content objects were rendered within the webpage. An object prioritizor may prioritize the content objects based on where the content objects were rendered. A delivery controller may adapt protocols for delivering the content objects to improve access to high-priority content objects.

Abstract: A point of presence includes edge servers having IP addresses and storing content, a switch/router that receives and forwards requests for content to the edge servers, a health monitoring server that gathers health information from the edge servers, and a dynamic request rerouting (DRR) server. The DRR server is connected with each of the edge servers. If the DRR server obtains a determination that one of the edge servers is down, it advertises a route including the IP address of the down edge server to the switch/router. The switch/router forwards a request for content, originally addressed to the down server, to the DRR server. The DRR server forwards the request to a working server that stores the content. The working server sends the content to the DRR server, the DRR server forwards the content back to the switch/router, and the switch/router responds to the original request with the content.

Abstract: Provided are methods, systems and computer program products for improving TCP stream transmissions by establishing a transmission schedule and making modifications to the timing and/or rate at which data packets are transmitted based on a timing of acknowledgment signals received in response to transmitted data packets.

Abstract: A method or system for transferring information during the domain name service (DNS) lookup to more effectively utilizing the content delivery network (CDN) is disclosed. Information gathered from DNS request is used to identify information on how to serve the content with a chosen IP address returned from the DNS lookup. The DNS server selects from a number of possible IP addresses after analyzing information from the DNS request and popularity of associated content. The different IP addresses will result in different edge servers providing content. An IP address could be provided for popular content in a way that will tend to populate more content caches from the pool of edge servers in one embodiment.

Abstract: In various aspects, provided herein are systems, methods and computer-program products for delivering content objects over the Internet from a content delivery network to end-user systems. The systems, methods and products described herein optionally utilize one or more techniques for reducing the delay associated with obtaining non-cached content objects from their respective origin servers, including by re-using existing open connections, by making use of a TCP hand-off technique and by transmitting updates to system digests simultaneous with the exchange of keepalive signals between servers.

Abstract: A system for securely managing uploaded content according to client-definable policies in remote storage configurations may include a content storage network with servers that are distributed in a plurality of geographic regions. The system may also include a policy engine that stores and processes policies that govern how content uploaded to the content storage network is stored. The system may additionally include a client portal that may be configured to receive a content object at the client device for upload to the content storage network, receive a policy or a selection of a policy that governs how the content object should be stored in the content storage network, and provide a status of how the policy is applied to the content object after the content object is uploaded to the content storage network.

Abstract: According to the invention, a content delivery network (CDN) for delivering content objects from a content provider to a recipient is disclosed. The CDN includes a dynamic pricing engine and a second web location. The dynamic pricing engine is coupled to a first web location. The first web location, which is associated with a content provider, allows the recipient to order a content object. The delivery quote is solicited by the first web location for delivering a content object one or more times. The second web location delivers the content object to a recipient system of the recipient. The second web location is associated with the dynamic pricing engine. The dynamic pricing engine automatically produces the delivery quote, which is affected by at least one of the content object or a web location of the recipient system.

Abstract: Systems and methods for gathering distributed information to improve routing that uses Anycast for assigning deliveries between a number of geographically-distant points of presence (POPs) are disclosed. The POPs share the same Internet protocol (IP) address. According to Anycast resolution, the Internet aids in assigning a content request initially to a POP. Delivery statistics are gathered from deliveries a the number of POPs and possibly other sources. Where it is determined that Anycast found the wrong POP, the content request is reassigned to another POP.
