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, the CDN service provider can utilize commands responsive to an initial request for a resource that causes the requesting client computing device to transmit one or more supplemental resource requests. Information associated with the processing of the sequence of resource requests can be used to measure CDN service provider latencies.

Claims

1. A computer-implemented system comprising:

a data store configured to store computer-executable instructions; and

a hardware processor in communication with the data store, the hardware processor corresponding to a service provider and configured to execute the computer-executable instructions to at least;

obtain, from a client computing device, a first request for content at an identifiable component of the service provider, the first request for content corresponding to an embedded resource identifier;

transmit responsive processing information, wherein the responsive processing information includes information for identifying an alternative resource identifier and a command for causing a subsequent request for content corresponding to the alternative resource identifier to be transmitted by the client computing device to the service provider;

obtain, from the client computing device, the subsequent request for content at an identifiable component of the service provider, the subsequent request for content corresponding to the alternative resource identifier; and

determine performance metric information corresponding to the first and subsequent requests for content, the performance metric information corresponding, at least in part, to a communication latency between the client computing device and respective identifiable components of the service provider for the first and subsequent requests for content.

2. The system as recited in claim 1, wherein the first and subsequent requests for content are received at separately identifiable components of the service provider.

3. The system as recited in claim 1, wherein the first and subsequent requests for content are received at a same identifiable component of the service provider.

4. The system as recited in claim 1, wherein the hardware processor is further configured to execute the computer-executable instructions to at least transmit a resource responsive to the subsequent request for content.

5. The system as recited in claim 1, wherein the hardware processor is further configured to execute the computer-executable instructions to at least receive at least a portion of the performance metric information from the client computing device.

6. The system as recited in claim 1, wherein the hardware processor is further configured to execute the computer-executable instructions to at least store information associated with the first request.

7. The system as recited in claim 1, wherein the hardware processor is further configured to execute the computer-executable instructions to at least store information associated with the subsequent request.

8. The system as recited in claim 1, wherein transmitting responsive processing information comprises transmitting responsive processing information at least in part based on a threshold corresponding to a number of commands provided by the service provider for causing subsequent resource requests for content.

9. The system as recited in claim 1, wherein transmitting responsive processing information comprises transmitting responsive processing information upon a determination that the client computing device is a particular type of client computing device.

10. The system as recited in claim 1, wherein transmitting responsive processing information comprises transmitting responsive processing information upon a determination that the first request is for a particular resource.

11. A computer-implemented method comprising:

obtaining, by a service provider, a first request for content at an identifiable component of the service provider, the first request for content corresponding to an embedded resource identifier, wherein the first request for content is generated by a client computing device;

transmitting, by the service provider, responsive processing information, wherein the responsive processing information includes information for identifying an alternative resource identifier and a command for causing a subsequent request for content corresponding to the alternative resource identifier to be transmitted by the client computing device to the service provider;

obtaining, by the service provider, the subsequent request for content at an identifiable component of the service provider, the subsequent request for content corresponding to the alternative resource identifier, wherein the subsequent request for content is generated by the client computing device; and

determining, by the service provider, performance metric information corresponding to the first and subsequent requests for content, the performance metric information corresponding, at least in part, to a communication latency between the client computing device and respective identifiable components of the service provider for the first and subsequent requests for content.

12. The method as recited in claim 11, wherein the embedded resource identifier corresponds to a uniform resource locator of the service provider.

13. The method as recited in claim 11, wherein the alternative resource identifier corresponds to a uniform resource locator of the service provider.

14. The method as recited in claim 11, wherein the command for causing a subsequent request for content corresponds to a hypertext transfer protocol command.

15. The method as recited in claim 11 further comprising providing, by the service provider, one or more resources responsive to the subsequent request for content corresponding to the alternative resource identifier.

16. The method as recited in claim 11, wherein the first and subsequent requests for content are received at separately identifiable components of the service provider.

17. The method as recited in claim 11, wherein the first and subsequent requests for content are received at a same identifiable component of the service provider.

18. The method as recited in claim 11, wherein transmitting responsive processing information comprises transmitting responsive processing information at least in part based on a threshold corresponding to a number of commands provided by the service provider for causing subsequent resource requests for content.

19. The method as recited in claim 11, wherein transmitting responsive processing information comprises transmitting responsive processing information upon a determination that the client computing device is a particular type of client computing device.

20. The method as recited in claim 11, wherein transmitting responsive processing information comprises transmitting responsive processing information upon a determination that the first request is for a particular resource.
