Abstract

A computer-based system and article of manufacture utilizing a single response time monitor, located on a non-origin node of a public or private network, for measuring the total roundtrip response time of a set of requests resulting from an original request having embedded HTML frames. The response time monitor builds a relationship tree for the original request and its embedded HTML frames. For each request from the set of requests resulting from the original request, including requests for the embedded HTML frames, the method uses the response time monitor to detect a start time and end time of each component of the request'"'"'s roundtrip response time in order to calculate each component'"'"'s duration. Later, the response time monitor calculates the total roundtrip response time by adding together the duration of all components of the original request and all its additional requests that have the same network address and port number.

Claims

1. A system for measuring a total roundtrip response time of a set of requests resulting from an original request having embedded HTML frames, the system comprising:

a processor; and

a response time monitor, located on a non-origin node of a public or private network which when executed by the processor is configured to;

(a) build a relationship tree for the original request and its embedded HTML frames;

(b) for the original request and each additional request from the set of requests resulting from the original request, include requests for the embedded HTML frames, detecting a start time and end time of each component of a roundtrip response time of the respective request in order to calculate a respective duration for each component;

(c) detect that the original request and the set of requests resulting from the original request have been completed upon the occurrence of a termination condition; and

(d) calculate the total roundtrip response time, including time needed for obtaining the embedded HTML frames, by using the relationship tree to aggregate respective round trip times of the original request and all the additional requests by adding together the duration of all their respective components.

2. The system according to claim 1, wherein the components have the same network address and port number as the original request.

3. The system according to claim 1, wherein the termination condition is the first to occur in time of a subsequent request for an HTML page and no additional requests being detected by the response time monitor for a predefined time period.

4. The system according to claim 1, wherein calculating the total roundtrip response time comprises aggregating the times of the original request and all the additional requests in serial mode, parallel mode or in a combination of the serial and parallel modes.

5. The system according to claim 1, wherein the network is using Hypertext Transfer Protocol (HTTP) or secured Hypertext Transfer Protocol (HTTPs) and Transmission Control Protocol/Internet Protocol (TCP/IP), and the request is compliant with the Hypertext Markup Language (HTML) request.

6. The system according to claim 1, wherein the response time monitor calculates the duration of each packet component of the original or additional request, or its response packet component separately, when the request or response is broken into packets during the network transfer.

7. The system according to claim 1, wherein the components of the roundtrip response time comprise a network time component, calculated as a time between an origin and the non-origin node, and a non-origin node time component.

8. The system according to claim 7, wherein the network time component:

includes an inbound network time of the original or additional request from an origin node to the non-origin node and an outbound network time returning a response back to the origin node, and

is calculated as a duration of the outbound network time component returning the response from the non-origin node back to the origin node and a duration of an acknowledgement from the origin node being received by the non-origin node.

9. The system according to claim 8, wherein the non-origin node comprises a first non-origin node using data from a second non-origin node, and wherein a duration of the roundtrip time component spent solely on the first non-origin node is calculated by subtracting from the non-origin node time a duration spent in the second non-origin node and a network time between the first and second non-origin nodes.

10. A non-transitory computer usable storage medium, embodying a program of instructions executable by the computer to perform a method, utilizing a single response time monitor located on a non-origin node of a public or private network, for measuring a total roundtrip response time of a set of requests resulting from an original request having embedded HTML frames, comprising:

(a) utilizing the response time monitor on the non-origin node for building a relationship tree for the original request and its embedded HTML frames; and

(b) for the original request and each additional request from the set of requests resulting from the original request, including requests for the embedded HTML frames, using the response time monitor to detect a start time and end time of each component of a roundtrip response time of the respective request in order to calculate a respective duration for each component;

(c) detecting that the original request and the set of requests resulting from the original request have been completed upon the occurrence of a termination condition; and

(d) calculating, by the response time monitor, the total roundtrip response time, including time needed for obtaining the embedded HTML frames, by using the relationship tree to aggregate respective round trip times of the original request and all the additional requests by adding together the duration of all their respective components.

11. The non-transitory computer usable storage medium according to claim 10, wherein the termination condition is the first to occur in time of a subsequent request for an HTML page and no additional requests being detected by the response time monitor for a predefined time period.

12. The non-transitory computer usable storage medium according to claim 10, wherein the termination condition is the first to occur in time of a subsequent request for an HTML page and no additional requests being detected by the response time monitor for a predefined time period.

13. The non-transitory computer usable storage medium according to claim 10, wherein calculating the total roundtrip response time comprises aggregating the times of the original request and all the additional requests in serial mode, parallel mode or in a combination of the serial and parallel modes.

14. The non-transitory computer usable storage medium according to claim 10, wherein the network is using Hypertext Transfer Protocol (HITP) or secured Hypertext Transfer Protocol (HTTPs) and Transmission Control Protocol/Internet Protocol (TCP/IP), and the request is compliant with the Hypertext Markup Language (HTML) request.

15. The non-transitory computer usable storage medium according to claim 10, wherein the response time monitor calculates the duration of each packet component of the original or additional request, or its response packet component separately, when the request or response is broken into packets during the network transfer.

19. A non-transitory computer usable storage medium, embodying a program of instructions executable by the computer to perform an operation, utilizing a single response time monitor, located on a non-origin node of a public or private network, for determining a total roundtrip response time to an origin node for a web page having embedded HTML frames, the operation comprising:
