Abstract

A computer-based system and method 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 request 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.

2. The method according to claim 1, further comprising a step of having the response time monitor calculate the roundtrip response time of the original and each said additional request by adding together the duration of all its components, wherein the components having the same network address and port number as the original request.

3. The method according to claim 2, further comprising a step of detecting when the set of requests resulting from the original request has been completed and having the response time monitor calculate the total roundtrip response time of the set of requests resulting from the original request, including the time needed for obtaining the embedded HTML frames, by aggregating time of the original request and all the additional requests by adding together the duration of all their components.

4. The method according to claim 3, wherein the original request is deemed completed either when the additional request requests an HTML page or when a period of inactivity lapses.

5. The method according to claim 3, wherein the total time is aggregated in serial mode, parallel mode or in a combination of the serial and parallel modes.

6. The method 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.

7. The method 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.

8. The method 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.

9. The method according to claim 8, 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.

10. The method according to claim 9, 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.

11. A system 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, comprising the means for:

(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 the request'"'"'s roundtrip response time in order to calculate each said component'"'"'s duration.

12. The system according to claim 11, further comprising means for having the response time monitor calculate the roundtrip response time of the original and each said additional request by adding together the duration of all its components, wherein the components having the same network address and port number as the original request.

13. The system according to claim 12, further comprising means for detecting when the set of requests resulting from the original request has been completed and having the response time monitor calculate the total roundtrip response time of the set of requests resulting from the original request, including the time needed for obtaining the embedded HTML frames, by aggregating time of the original request and all the additional requests by adding together the duration of all their components.

14. The system according to claim 13, wherein the original request is deemed completed either when the additional request requests an HTML page or when a period of inactivity lapses.
