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 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 method for processing content comprising:

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

transmitting, by the service provider, responsive processing information, wherein the responsive 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 a resource at an identifiable component of the service provider, the subsequent request for a resource corresponding to the alternative resource identifier, wherein the subsequent request for the resource is generated by the client computing device; and

determining, by the service provider, latency information corresponding to the two requests for content, the latency information corresponding to communication latency between the client computing device and respective identifiable components of the service provider for the two requests for content.

2. The method as recited in claim 1, wherein the embedded resource identifier corresponds to a uniform resource locator of the service provider.

3. The method as recited in claim 1, wherein the alternative resource identifier corresponds to a uniform resource locator of the service provider.

4. The method as recited in claim 1, wherein the command for causing a subsequent request for content corresponds to a hypertext transfer protocol command.

5. The method as recited in claim 1 further comprising obtaining latency information corresponding to the two requests for content, the latency information corresponding to a communication latency between the client computing device and respective identifiable components of the service for the two requests for content.

6. The method as recited in claim 1 further comprising providing, by the service provider, one or more resources responsive to the subsequent request for a resource corresponding to the alternative resource identifier.

7. The method as recited in claim 1, wherein the two requests for content are received at separately identifiable components of the service provider.

8. The method as recited in claim 1, wherein the two requests for content are received at a same identifiable component of the service provider.

9. A computer-implemented method for processing content comprising:

transmitting, by a client computing device, a request for a resource, the request for a resource corresponding to an embedded resource identifier, wherein the request for the resource is received by a first identifiable component of a service provider responsive to the service provider providing originally requested content including the embedded resource identifier to the client computing device;

obtaining, by the client computing device, responsive processing information from the service provider, wherein the responsive 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;

transmitting, by the client computing device, the subsequent request for a resource to a second identifiable component of the service provider, the subsequent request for a resource corresponding to the alternative resource identifier, wherein the subsequent request for the resource is generated by the client computing device;

determining, by the client computing device, metric information corresponding to the two requests for content, the metric information corresponding to communications between the client computing device and the first and second separately identifiable components of the service provider for the two requests for content; and

transmitting the metric information to the service provider.

10. The method as recited in claim 9, wherein the embedded resource identifier corresponds to a uniform resource locator of the service provider.

11. The method as recited in claim 9, wherein the alternative resource identifier corresponds to a uniform resource locator of the service provider.

12. The method as recited in claim 9, wherein the command for causing a subsequent request for content corresponds to a hypertext transfer protocol command.

13. The method as recited in claim 9, wherein the metric information corresponding to communications between the client computing device and the first and second separately identifiable components of the service provider includes latency information corresponding to a communication latency between the client computing device and each of the separately identifiable components of the service provider for the two requests for content.

14. The method as recited in claim 9, wherein the metric information corresponds to latency information between the client computing device and the first and second separately identifiable components of the service provider.

15. The method as recited in claim 9 further comprising receiving, by the client computing device, one or more resources responsive to the subsequent request for a resource corresponding to the alternative resource identifier.

16. The method as recited in claim 9, wherein transmitting the subsequent request for the resource includes transmitting the subsequent request for the resource to the second identifiable component of the service provider.

17. The method as recited in claim 9, wherein transmitting the subsequent request for the resource includes transmitting the subsequent request for the resource to the first identifiable component of the service provider.

18. A computer-implemented system for processing content, the 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 a request for a resource at an identifiable component of the service provider, the request for a resource corresponding to an embedded resource identifier, wherein the request for the resource is generated by a client computing device responsive to obtaining originally requested content including the embedded resource identifier from the service provider;

transmit responsive processing information, wherein the responsive 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 the subsequent request for a resource at an identifiable component of the service provider, the subsequent request for a resource corresponding to the alternative resource identifier, wherein the subsequent request for the resource is generated by the client computing device;

determine performance metric information corresponding to the two 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 two requests for content; and

update the performance metric information according to the latency information.

19. The system as recited in claim 18, wherein the hardware processor is further configured to execute the computer-executable instructions to at least obtain latency information corresponding to the two requests for content, the latency information corresponding to a communication latency between the client computing device and respective identifiable components of the service provider for the two requests for content.

20. The system as recited in claim 18, wherein the two requests for content are received at separately identifiable components of the service provider.

21. The system as recited in claim 18, wherein the two requests for content are received at a same identifiable component of the service provider.

22. The system as recited in claim 18, 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 a resource.

23. The system as recited in claim 18, 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.
