Abstract

A CDN system and method to provide access and a better user experience based on a novel CDN architecture wherein each edge server may be outside of an Internet data center, may be stationary or mobile, may be intermittently connected to the multi-tiered content delivery network, may be connected to a last mile over Wi-Fi and may be physically located in a place of interest.

Claims

1. A data delivery system, comprising:

a multi-tiered content delivery network having an origin server at a first tier, one or more mid servers at a second tier connected to the origin server and a plurality of edge servers at a third tier connected to one or more mid servers and a plurality of computing devices that make requests to the content delivery network using a cellular data connection and a WiFi connection;

wherein each edge server has a processor and memory and may be outside of an Internet data center, is one of stationary and mobile, may be intermittently connected to the multi-tiered content delivery network and a particular edge server is physically located in a place of interest and the processor of the particular edge server caches content based on user demographics and service access patterns associated with the place of interest and each edge server operates with and without connectivity to the multi-tiered content delivery network and the processor of each particular edge server performs machine learning to generate a list of content based on user demographics and service access patterns associated with the place of interest and caches the content in the generated list of content and pulls the pieces of content on the generated content list from the content delivery network for the place of interest; and

wherein the content delivery network may implement a hybrid push and pull content model in which each edge server pulls content from the content delivery network for the place of interest and pushes the content, when requested by each computing device, to that computing device with and without access to the Internet.

2. The system of claim 1, wherein the plurality of edge servers may further comprise a static edge server that has a Wi-Fi interface and a wired, high speed connection to the one or more mid servers.

3. The system of claim 2, wherein the plurality of edge servers may further comprise a mobile edge server that connects to the static edge server over a Wi-Fi SSID for high speed communications and also connects to the multi-tiered content delivery network infrastructure over a cellular data network.

4. The system of claim 3, wherein each edge server has an attached WiFi circuit covering the place of interest configured to deliver the content hosted by the edge server to a user at the place of interest over a Local Area Network (LAN).

5. The system of claim 1, wherein each edge server further performs one or more of the following processes:

generating security keys, generating ad tags and generating API responses.

6. The system of claim 5, wherein each edge server is always one hop away from the computing device thereby providing a faster data delivery and facilitating better user experience.

7. The system of claim 6, wherein the multi-tiered content delivery network uses a dedicated last mile that is not shared with other services running on the Internet, thereby providing a faster data delivery and facilitating better user experience.

8. The system of claim 7, wherein each edge server enables a user that doesn'"'"'t have access to the internet last mile (one of cellular data or Wi-Fi) to experience the full functionality of a digital service when the edge server is connected to the multi-tiered content delivery network infrastructure.

9. The system of claim 8, wherein each edge server enables a user that doesn'"'"'t have access to the internet last mile (one of cellular data or Wi-Fi) to experience a digital service, although with certain limited functionality when the edge server is not connected to the multi-tiered content delivery network infrastructure.

10. The system of claim 9, wherein each chunk of data transferred from each edge server does not add load on the Internet Infrastructure or the Internet last mile, thereby freeing up bandwidth on the existing internet infrastructure.

11. A method for accessing digital data, comprising:

providing a multi-tiered content delivery network having an origin server at a first tier, one or more mid servers at a second tier connected to the origin server and a plurality of edge servers at a third tier connected to the one or more mid servers and a plurality of computing devices that make requests to the content delivery network using a cellular data connection and a WiFi connection wherein each edge server may be outside of an Internet data center, is one of stationary and mobile, may be intermittently connected to the multi-tiered content delivery network and a particular edge server is physically located in a place of interest which would allow the particular edge server to cache content based on user demographics and service access patterns associated with the place of interest; and

obtaining, by each edge server, a plurality of pieces of content from the higher level tiers of the multi-tiered content delivery network for the place of interest associated with each edge server;

performing a hybrid push and pull content delivery model in which each edge server pulls content from the content delivery network for the place of interest and pushes the content with and without connectivity to the multi-tiered content delivery network, when requested by each computing device, to that computing device with and without access to the Internet; and

performing, at each edge server, machine learning to generate a list of content based on user demographics and service access patterns associated with the place of interest and caching, at each server, the content in the generated list of content by pulling the pieces of content on the generated content list from the content delivery network for the place of interest.

12. The method of claim 11, wherein the plurality of edge servers may further comprise a static edge server that has a Wi-Fi interface and a wired, high speed connection to the one or more mid servers.

13. The method of claim 12, wherein the plurality of edge servers may further comprise a mobile edge server that connects to a static edge server over a Wi-Fi SSID for high speed communications and also connects to the multi-tiered content delivery network infrastructure over a cellular data network.

14. The method of claim 13 further comprising covering, by each edge server having an attached WiFi circuit, the place of interest configured to deliver the content hosted by the edge server to a user at the place of interest over a Local Area Network (LAN).

15. The method of claim 11, wherein each edge server further performs one of more of the following processes:

generating security keys, generating ad tags and generating API responses.

16. The method of claim 15, wherein each edge server is always one hop away from the computing device thereby providing a faster data delivery and facilitating better user experience.

17. The method of claim 16, wherein the multi-tiered content delivery network uses a dedicated last mile that is not shared with other services running on the Internet, thereby providing a faster data delivery and facilitating better user experience.

18. The method of claim 17, wherein each edge server enables a user that doesn'"'"'t have access to the internet last mile (one of cellular data or Wi-Fi) to experience the full functionality of a digital service when the edge server is connected to the multi-tiered content delivery network infrastructure.

19. The method of claim 18, wherein each edge server enables a user that doesn'"'"'t have access to the internet last mile (one of cellular data or Wi-Fi) to experience a digital service, although with certain limited functionality when the edge server is not connected to the multi-tiered content delivery network infrastructure.

20. The method of claim 19, wherein each chunk of data transferred from each edge server does not add load on the Internet Infrastructure or the Internet last mile, thereby freeing up bandwidth on the existing internet infrastructure.
