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 computer-implemented method comprising:

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

transmitting translation code to a content provider, wherein the content provider embeds the translation code in content provided in response to a content request from a client computing device, and wherein execution of the translation code by a client computing device instructs the client computing device to request translation information pertaining to routing information for resources included in the requested content;

receiving a translation information request from the client computing device;

generating translation information which instructs the client computing device to modify one or more resource identifiers associated with resources included in the content to generate one or more modified resource identifiers based on a popularity of a corresponding resource; and

transmitting the generated translation information to the client computing device.

2. The computer-implemented method of claim 1, wherein the one or more resource identifiers and the one or more modified resource identifiers are uniform resource locators.

3. The computer-implemented method of claim 2, wherein popularity information is included in an individual uniform resource locator.

4. The computer-implemented method of claim 3, wherein the popularity information is included in a DNS portion of the individual uniform resource locator.

5. The computer-implemented method of claim 2, wherein information directing the CDN service provider to popularity information of a corresponding resource is included in an individual uniform resource locator.

6. The computer-implemented method of claim 5, wherein the information directing the CDN service provider to popularity information of a corresponding resource is included in a DNS portion of the individual uniform resource locator.

7. The computer-implemented method of claim 2, wherein a first resource identifier of the one or more resource identifiers corresponds to a first uniform resource locator of the content provider and the individual modified resource identifier corresponds to a second uniform resource locator of the CDN service provider.

8. The computer-implemented method of claim 1, wherein the individual modified resource identifier specifies a resource identifier that requires further processing in order to identify a network address of a cache server component that is capable of providing the requested content.

9. The computer-implemented method of claim 8, wherein a DNS query for the individual modified resource identifier is resolved to a point of presence server associated with the CDN service provider.

10. The computer-implemented method of claim 1, wherein the translation information request comprises one or more of identification of the content provider, identification of the client computing device, the type of the requested content, and the size of the requested content.

11. The computer-implemented method of claim 1, wherein popularity information is included in the one or more resource identifiers.

12. The computer-implemented method of claim 1, wherein information directing the CDN service provider to popularity information of a corresponding resource is included in the one or more resource identifiers.

13. A system comprising:

at least one computing device of a content delivery network (CDN) service provider, the at least one computing device operative to;

transmit translation code to a content provider, wherein the content provider embeds the translation code in content provided in response to a content request from a client computing device, and wherein execution of the translation code by a client computing device instructs the client computing device to request translation information pertaining to routing information for resources included in the requested content;

receive a translation information request from the client computing device;

generate translation information which instructs the client computing device to modify one or more resource identifiers associated with resources included in the content to generate one or more modified resource identifiers based on a popularity of a corresponding resource; and

transmit the generated translation information to the client computing device.

14. The system of claim 13, wherein the one or more resource identifiers and the one or more modified resource identifiers are uniform resource locators.

15. The system of claim 14, wherein popularity information is included in an individual uniform resource locator.

16. The system of claim 15, wherein the popularity information is included in a DNS portion of the individual uniform resource locator.

17. The system of claim 14, wherein information directing the CDN service provider to popularity information of a corresponding resource is included in an individual uniform resource locator.

18. The system of claim 17, wherein the information directing the CDN service provider to popularity information of a corresponding resource is included in a DNS portion of the individual uniform resource locator.

19. The system of claim 14, wherein a first resource identifier of the one or more resource identifiers corresponds to a first uniform resource locator of the content provider and the individual modified resource identifier corresponds to a second uniform resource locator of the CDN service provider.

20. The system of claim 13, wherein the individual modified resource identifier specifies a resource identifier that requires further processing in order to identify a network address of a cache server component that is capable of providing the requested content.

21. The system of claim 20, wherein a DNS query for the individual modified resource identifier is resolved to a point of presence server associated with the CDN service provider.

22. The system of claim 13, wherein the translation information request comprises one or more of identification of the content provider, identification of the client computing device, a type of the requested content, and a size of the requested content.

23. The system of claim 13, wherein popularity information is included in the one or more resource identifiers.

24. The system of claim 13, wherein information directing the CDN service provider to popularity information of a corresponding resource is included in the one or more resource identifiers.
