Abstract

Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. The request routing functionality can correspond to the processing of domain name service (“DNS”) requests for resources by computing devices and the resolution of the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Based on the processing resource requests initiated by a client computing device, a CDN service provider can obtain performance information from client computing devices and correlate the performance information into a prioritized list for classes of client computing devices. The prioritized list can be utilized in resolving subsequent DNS queries.

Claims

1. A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, direct a service provider computing system to perform operations comprising:

providing, by the service provider computing system, at least one identifier for identifying an embedded resource provided by a content provider computing system;

generating, by the service provider computing system, at least one list based, at least in part, on performance information associated with previous requests for the embedded resource, wherein a generated list identifies point of presence servers associated with a class of computing devices;

obtaining, by the service provider computing system, a request for content from a client computing device responsive to the at least one identifier for the embedded resource provided by the content provider computing system;

determining, by the service provider computing system, a class of client computing devices associated with the client computing device based, at least in part, on an address associated with the client computing device;

determining, by the service provider computing system, whether a list of the at least one list is associated with the determined class of computing devices;

if the list is determined to be associated with the determined class of computing devices, resolving, by the service provider computing system, the request for content from the client computing device by identifying at least one point of presence server associated with the determined class of client computing devices from the list; and

if the list is determined to not be associated with the determined class of computing devices, resolving, by the service provider computing system, the request for content based, at least in part, on location information associated with the request.

2. The non-transitory computer-readable storage medium as recited in claim 1, wherein the performance information relates to latency information.

3. The non-transitory computer-readable storage medium as recited in claim 1, wherein the at least one identifier corresponds to a uniform resource locator of the service provider computing system.

4. A method for processing content comprising:

obtaining, by a service provider computing system, performance information associated with processing of requests for resources from at least one class of client computing devices;

generating at least one list based, at least in part, on the performance information, wherein a generated list identifies point of presence servers associated with a class of the at least one class of client computing devices;

obtaining, by the service provider computing system, a domain name service request from a client computing device;

determining, by the service provider computing system, a class of computing devices of the at least one class of client computing devices associated with the client computing device;

determining, by the service provider computing system, whether a list is associated with the determined class of computing devices;

if a list is determined to be associated with the determined class of computing devices, resolving, by the service provider computing system, the domain name service request by identifying at least one point of presence server associated with the determined class of client computing devices from the list; and

if a list is not determined to be associated with the identified class of computing devices, resolving, by the service provider computing system, the domain name service request based, at least in part, on location information associated with the request.

5. The method as recited in claim 4 further comprising providing, by a service provider computing system, an identifier for identifying one or more the resources.

6. The method as recited in claim 5, wherein the at least one identifier corresponds to a uniform resource locator of at least one of a content provider computing system or the service provider computing system.

7. The method as recited in claim 4 further comprising conducting, by the service provider computing system, availability checking prior to resolving the domain name service request.

8. The method as recited in claim 4, wherein the determined class of computing device associated with the client computing device corresponds to an association of a domain name server resolver component.

9. The method as recited in claim 4, wherein the determined class of computing device associated with the client computing device corresponds to an association of at least a portion of a network address.

10. The method as recited in claim 4, wherein obtaining the performance information associated with processing of a request for resources includes obtaining performance information from the client computing device executing code associated with an embedded resource identifier.

11. The method as recited in claim 4, wherein obtaining the performance information associated with processing of a request for a resource includes obtaining performance information from a content provider computing system executing code associated with the embedded resource identifier.

12. A computer-implemented system for processing content, the system comprising:

an electronic data store configured to store performance information associated with at least one class of computing devices, wherein the performance information is associated with requests for content; and

a computing system in communication with the electronic data store and comprising a processor, the processor configured to execute specific computer-executable instructions to at least;

generate at least one list based, at least in part, on the performance information, wherein a generated list identifies point of presence servers associated with a class of the at least one class of computing devices;

obtain a domain name service request from a client computing device;

determine a class of computing devices of the at least one class of computing devices associated with the client computing device;

determine whether a list is associated with the identified class of computing devices;

if a list is determined to be associated with the determined class of computing devices, resolve the domain name service request by identifying at least one point of presence server associated with the determined class of client computing devices from the list; and

if a list is determined not to be associated with the determined class of computing devices, resolve the domain name service request based at least in part on location information associated with the request.

13. The system as recited in claim 12, wherein the requests for content are associated with an identifier, wherein the identifier corresponds to a uniform resource locator of at least one of a service provider or a content provider.

14. The system as recited in claim 12, wherein the class of computing device corresponds to an association of a domain name server resolver component.

15. The system as recited in claim 12, wherein the class of computing device corresponds to an association of at least a portion of a network address.

16. The system as recited in claim 12, wherein the processor is further configured to execute specific computer-executable instructions to at least conduct availability checking prior to resolving the domain name service request.

17. The system as recited in claim 12, wherein the performance information corresponds to latency information associated with processing the domain name service request.

18. The system as recited in claim 12, wherein the performance information is generated by a content provider.
