Abstract

Systems and method for the management and processing of resource requests by a service provider, such as a content delivery network (“CDN”) service provider, on behalf of a content provider are provided. The CDN service provider can measure the performance associated with the delivery of resources to a requesting client computing devices from various computing devices associated with the CDN service provider. In one embodiment, a client computing device can execute code, such as scripts, that cause the client computing device to transmit requests to different computing devices associated with the CDN service provider'"'"'s domain. Information associated with the processing of the responses can be used to measure CDN service provider latencies.

Claims

1. A method comprising:

providing, by a service provider, executable code for generating a set of requests to the service provider, wherein the executable code includes instructions for configuring at least two requests for content from the set of requests to be directed to separately identified components of the service provider;

obtaining, by the service provider, the at least two requests from a client computing device, wherein each of the at least two requests is generated by the client computing device as a function of having executed the provided executable code;

processing, by the service provider, the at least two requests; and

determining, by the service provider, latency information associated with the at least two requests from the client computing device, the latency information corresponding to a communication latency between the client computing device and the separately identified components of the service provider.

2. The method as recited in claim 1, wherein providing, by the service provider, executable code for generating the set of requests to the service provider includes providing, by the service provider, the executable code to a content provider for embedding in a network resource.

3. The method as recited in claim 1, wherein the executable code corresponds to a script.

4. The method as recited in claim 1 further comprising providing at least one embedded resource identifier corresponding to an additional resource to be provided by the service provider.

5. The method as recited in claim 1, wherein the service provider corresponds to a content delivery network service provider.

6. The method as recited in claim 1 further comprising providing a response to at least one of the at least two requests transmitted by the client computing device.

7. A system comprising:

a data store for storing performance metric information associated with processing resource requests; and

a computing system in communication with said data store that is operative to;

provide information for generating a series of requests to a service provider, wherein the information includes instructions for configuring at least two requests for content from the series of requests to be directed to separately identified components of the service provider;

obtain the at least two requests from a client computing device, wherein each of the at least two requests is generated by the client computing device having executed the provided executable code;

process the at least two requests;

determine latency information associated with each of the at least two requests, wherein the latency information corresponds to a communication latency between the client computing device and the separately identified components of the service provider; and

update performance metric information according to the latency information.

8. The system as recited in claim 7, wherein the information for generating the series of requests to the service provider corresponds to executable code executable by a software application associated with the client computing device.

9. The system as recited in claim 7, wherein processing each of the at least two requests includes providing a resource responsive to each request.

10. The system as recited in claim 7, wherein the information for generating a series of requests to the service provider corresponds to a script.

11. The system as recited in claim 7, wherein the computing system is further operative to provide at least one embedded resource identifier corresponding to an additional resource to be provided by the service provider.

12. The system as recited in claim 7, wherein the computing system determines latency information associated with the at least two requests based on latency information obtained from the client computing device associated with the at least two requests and provided to the computing system responsive to execution of the executable code.

13. A non-transitory, computer-readable storage media comprising computer-executable instructions for processing content, wherein the computer-executable instructions, when executed by a computer system, cause the computer system to:

provide, by a service provider, executable code for generating a set of requests to the service provider, wherein the executable code includes instructions for configuring at least two requests for content from the set of requests to be directed to separately identified components of the service provider;

obtain, by the service provider, the at least two requests from a client computing device, wherein each of the at least two requests is generated by the client computing device as a function of having executed the provided executable code;

process, by the service provider, the at least two requests; and

determine, by the service provider, latency information associated with the at least two requests from the client computing device, the latency information corresponding to a communication latency between the client computing device and the separately identified components of the service provider.

14. The non-transitory, computer-readable storage media as recited in claim 13, wherein providing, by the service provider, executable code for generating the set of requests to the service provider includes providing, by the service provider, the executable code to a content provider for embedding in a network resource.

15. The non-transitory, computer-readable storage media as recited in claim 13, wherein the computer-executable instructions further cause the computer system to provide at least one embedded resource identifier corresponding to an additional resource to be provided by the service provider.

16. The non-transitory, computer-readable storage media as recited in claim 13, wherein the executable code corresponds to a script.

17. The non-transitory, computer-readable storage media as recited in claim 13, wherein the computer-executable instructions further cause the computer system to provide a response to at least one of the at least two requests transmitted by the client computing device.
