System and method for distributed network performance management
A distributed network performance management system and method that distributes a large portion of the network performance management to wireless client devices connected to the network. Rather than rely on a central server to perform the bulk of network performance management, a distributed network performance management system offloads much of the work of service quality testing, reporting, and troubleshooting to wireless client devices that are connected to the network. It utilizes spare computing power and storage space on the wireless client devices to reduce the cloud operation costs of the system including such things as bandwidth requirements, data storage requirements, and data processing requirements.
1. A system for distributed network performance management, comprising:
a control server, comprising a memory, a processor, and a first plurality of programming instructions stored in the memory which, when operating on the processor, cause the control server to:
send configuration instructions to a distributed testing application installed on a plurality of client devices, the configuration instructions for each device comprising a level of autonomy of the client device;
receive network test results from the client device;
determine a condition of performance of the network from the received data; and
change the configuration instructions for one or more of the plurality of client devices based on the condition of performance of the network; and
a distributed testing application comprising a second plurality of programming instructions stored in a memory of, and operating on a processor of, each of the plurality of client devices, wherein the second plurality of programming instructions, when operating on the processor of the respective client device, causes the respective client device to:
receive the configuration instructions;
establish a network testing regime, the network testing regime being based on the level of autonomy and comprising:
a selection of one or more types of network testing to be performed;
a schedule for performing the one or more types of network testing;
a selection of one or more granularity levels for the one or more types of network testing; and
a schedule for reporting network test results of the one or more types of network testing to the control server or a third-party server; and
report network test results to the control server or the third-party server;
further comprising a hierarchy of client devices wherein some of the plurality of client devices act as an intermediary control server for other client devices.
2. The system of claim 1 , further comprising a service level manager comprising a second plurality of programming instructions stored in the memory which, when operating on the processor, cause the control server to:
include a service level command in the configuration instructions sent to one or more groups of client devices, the service level command comprising a service level for testing and reporting;
wherein the service level command causes each client device a given group to adjust its network testing regime based on the service level.

decreasing network testing frequency, granularity, or both, where the client device does not detect a problem with network performance.
5. The system of claim 4 , wherein the configuration instructions further comprise instructions to capture geolocation data regarding the client device's geolocation and provide the geolocation data in conjunction with the network test results.
6. The system of claim 1 , wherein the configuration instructions further comprise instructions to additionally send test results to a third-party server for analysis and reporting.
7. The system of claim 1 , wherein the configuration instructions further comprise instructions to only send detailed test results to a third party while sending only the results at the level of detail required by the control server to manage the statistical sampling and testing regimes.
8. The system of claim 1 , wherein at least one client device is a wireless device, and at least one of the one or more types of network testing is a test of wireless communication performance.
9. The system of claim 8 , wherein the distributed testing application further comprises a wireless performance monitor, the wireless performance monitor comprising a third plurality of programming instructions stored in the memory of, and operating on the processor of, the client device, wherein the third plurality of programming instructions, when operating on the processor of the client device, causes the client device to:
capture wireless packet data from the wireless device driver of the client device;
extract frame data from the wireless packet data; and
calculate an indicator of wireless performance from the extracted frame data.
10. A method for distributed network performance management, comprising the steps of:
sending configuration instructions from a control server to a distributed testing application installed on a plurality of client devices, the configuration instructions for each device comprising a level of autonomy of the client device
receiving reported network test results from the client device;
determining a condition of performance of the network from the reported data;
changing the configuration instructions for one or more of the plurality of client devices based on the condition of performance of the network; and
wherein the distributed testing application, operating on each of the plurality of client devices, causes the respective client device to:
receive the configuration instructions;
establish a network testing regime, the network testing regime being based on the level of autonomy and comprising:
a selection of one or more types of network testing to be performed;
a schedule for performing the one or more types of network testing;
a selection of one or more granularity levels for the one or more types of network testing; and
a schedule for reporting network test results of the one or more types of network testing to the control server or a third party server; and
report network test results to the control server or the third-party server; and
establishing a hierarchy of client devices wherein some of the plurality of client devices act as an intermediary control server for other client devices.
11. The method of claim 10 , further comprising the step of using a service level manager to:
include a service level command in the configuration instructions sent to one or more groups of client devices, the service level command comprising a service level for testing and reporting;
wherein the service level command causes each client device a given group to adjust its network testing regime based on the service level.
12. The method of claim 11 , further comprising the step of determining the selection of tests, the schedule for testing, and the schedule for reporting of the network testing regime for each device in the given group based on statistical sampling methodologies.
