Abstract

The technology disclosed relates to refined survey of Internet infrastructures. A pattern of measurements is disclosed that can improve data collection by increasing the number of measurements per survey session according to a function described in areas that have few measurements, and decreasing the average number of measurements per session in heavily measured areas. These are new problems that arise from implementation of technology developed by these inventors and their colleagues.

Claims

1. A method of determining how many infrastructure performance measurements to take during a session, the method including:

accessing an average number of measurements per session (“

MPS”

) value;

using an integer part of the MPS value to determine a base number of infrastructure performance measurements to take during the session,

the infrastructure performance measurements are measured between a survey code running as part of the session and a target resource hosted by a particular infrastructure and

the session includes delivery of the survey code from a host web based content to a web client; and

comparing a fractional part of the MPS value to a random or pseudo random sample value and determining whether to satisfy the fractional part of the MPS value by taking an additional measurement during the session; and

causing the base number of measurements plus the additional measurement, if so determined, to be taken.

2. The method of claim 1, wherein the MPS value is calculated using a logarithmic function of a number of measurement sessions in a time period.

3. The method of claim 1, wherein the MPS value is calculated using a logarithmic function of number of measurement sessions per day in a request grouping that includes the web client.

4. The method of claim 1, wherein the MPS value is calculated using an asymptotic function of number of sessions in a time period.

5. The method of claim 1, wherein the MPS value is taken from a table that uses number of sessions in a time period as a lookup index.

6. The method of claim 1, further including the random or pseudo random sample value being accessed and compared to the fractional part of the MPS value by the survey code running on the web client.

7. The method of claim 1, further including the random or pseudo random sample value being accessed and compared to the fractional part of the MPS value prior to delivery of the survey code to the web client and the survey code reflecting whether to satisfy the fraction part during the session.

8. The method of claim 1, further including receiving from the web client a number of measurements responsive to the base number and the determination of whether to satisfy the fractional part.

9. The method of claim 1, further including the web client transmitting to an access quality monitor a number of measurements responsive to the base number and the determination of whether to satisfy the fractional part.

10. A system that determines how many infrastructure performance measurements to take during a session, the system including:

a processor and memory coupled to the processor, the memory storing program instructions that, when executed on the processor, cause;

accessing an average number of measurements per session (“

MPS”

) value;

using an integer part of the MPS value to determine a base number of infrastructure performance measurements to take during the session,

the infrastructure performance measurements are measured between a survey code running as part of the session and a target resource hosted by a particular infrastructure and

the session includes delivery of the survey code from a host web based content to a web client; and

comparing a fractional part of the MPS value to a random or pseudo random sample value and determining whether to satisfy the fractional part of the MPS value by taking an additional measurement during the session; and

causing the base number of measurements plus the additional measurement, if so determined, to be taken.

11. The system of claim 10, wherein the MPS value is calculated using a logarithmic function of number of measurement sessions per day in a request grouping that includes the web client.

12. The system of claim 10, wherein the MPS value is calculated using an asymptotic function of number of sessions in a time period.

13. The system of claim 10, wherein the MPS value is taken from a table that uses number of sessions in a time period as a lookup index.

14. The system of claim 10, further including the random or pseudo random sample value being accessed and compared to the fractional part of the MPS value prior to delivery of the survey code to the web client and the survey code reflecting whether to satisfy the fraction part during the session.

15. The system of claim 10, further including receiving from the web client a number of measurements responsive to the base number and the determination of whether to satisfy the fractional part.

16. A computer readable program product that tangibly embodies instructions that, when executed by at least one processor, cause the processor to determine how many infrastructure performance measurements to take during a session, the computer readable program product including:

access an average number of measurements per session (“

MPS”

) value;

use an integer part of the MPS value to determine a base number of infrastructure performance measurements to take during the session,

the infrastructure performance measurements are measured between a survey code running as part of the session and a target resource hosted by a particular infrastructure and

the session includes delivery of the survey code from a host web based content to a web client; and

compare a fractional part of the MPS value to a random or pseudo random sample value and determine whether to satisfy the fractional part of the MPS value by taking an additional measurement during the session; and

cause the base number of measurements plus the additional measurement, if so determined, to be taken.

17. The computer readable program product of claim 16, wherein the MPS value is calculated using a logarithmic function of a number of measurement sessions in a time period.

18. The computer readable program product of claim 16, wherein the MPS value is calculated using an asymptotic function of number of sessions in a time period.

19. The computer readable program product of claim 16, wherein the MPS value is taken from a table that uses number of sessions in a time period as a lookup index.

20. The computer readable program product of claim 16, further including the random or pseudo random sample value being accessed and compared to the fractional part of the MPS value by the survey code running on the web client.

21. The computer readable program product of claim 16, further including receiving from the web client a number of measurements responsive to the base number and the determination of whether to satisfy the fractional part.
