Abstract

A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computer transmits a request for content from a content provider. The content provider utilizes executable code, such as translation request code, for facilitating request routing utilizing popularity information. The translation request code, may direct a client computing device to request further translation request code and/or translation information. Thereafter, the client issues a DNS query with the translated information including popularity information. The content delivery network service provider can then either resolve the DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat until a DNS nameserver resolves a DNS query from the client computing device.

Claims

1. A system comprising:

at least one computing device corresponding to a content delivery network (CDN) provider and operative to;

receive a request, generated by a client computing device, for translation information for a resource identifier originally provided to the client computing device by a content provider;

generate translation information responsive to the request, wherein the translation information provides instructions for the client computing device to generate a modified resource identifier by modifying the resource identifier to include information pertaining to popularity of the requested resource; and

cause transmission of the translation information to the client computing device.

2. The system of claim 1, wherein the resource identifier and modified resource identifier are uniform resource locators.

3. The system of claim 2, wherein at least a portion of the popularity information is included in the uniform resource locator of the modified resource identifier.

4. The system of claim 3, wherein the at least a portion of the popularity information is included in a DNS portion of the uniform resource locator of the modified resource identifier.

5. The system of claim 2, wherein the modified resource identifier includes at least a portion of the uniform resource locator of the resource identifier.

6. The system of claim 1, wherein the translation information request comprises popularity information.

7. The system of claim 6, wherein the popularity information of the translation information request is included as a part of the resource identifier.

8. The system of claim 1, wherein the popularity information is retrieved from the CDN provider.

9. The system of claim 8, wherein the popularity information comprises a frequency of received resource requests.

10. The system of claim 1, wherein modification of the resource identifier includes replacement of the resource identifier.

11. A computer-implemented method comprising:

as implemented by one or more computing devices configured with specific executable instructions, the one or more computing devices corresponding to a content delivery network (CDN) provider,

receiving a request for translation information for a resource identifier originally provided to the client computing device by a content provider;

generating translation information responsive to the request, wherein the translation information provides instructions for the client computing device to generate a modified resource identifier by modifying the resource identifier to include information pertaining to popularity of the requested resource; and

causing transmission of the translation information to the client computing device.

12. The computer-implemented method of claim 11, wherein the resource identifier and modified resource identifier are uniform resource locators.

13. The computer-implemented method of claim 12, wherein at least a portion of the popularity information is included in the uniform resource locator of the modified resource identifier.

14. The computer-implemented method of claim 13, wherein the at least a portion of the popularity information is included in a DNS portion of the uniform resource locator of the modified resource identifier.

15. The computer-implemented method of claim 12, wherein the modified resource identifier includes at least a portion of the uniform resource locator of the resource identifier.

16. The computer-implemented method of claim 11, wherein the translation information request comprises popularity information.

17. The computer-implemented method of claim 16, wherein the popularity information of the translation information request is included as a part of the resource identifier.

18. The computer-implemented method of claim 11, wherein the popularity information is retrieved from the CDN provider.

19. The computer-implemented method of claim 18, wherein the popularity information comprises a frequency of received resource requests.

20. The computer-implemented method of claim 11, wherein modification of the resource identifier includes replacement of the resource identifier.
