Adaptive multi-phase network policy optimization

One or more non-transitory computer-readable storage media, storing one or more sequences of instructions, which when executed by one or more processors cause performance of:

• sending a default network policy to a first portion of a plurality of user devices, wherein the default network policy assigns one or more TCP parameter values to a default value associated with the one or more TCP parameter values;
• sending an adjusted network policy to a second portion of the plurality of user devices, wherein the adjusted network policy assigns the one or more TCP parameter values to an adjusted value;
• aggregating network traffic data received from the plurality of user devices, wherein the aggregated network traffic data records outcomes of download requests from the plurality of user devices;
• analyzing performance metrics derived from the aggregated network data by comparing network traffic data values received from the first portion of user devices and network traffic data values received from the second portion of user devices;
• estimating a best value for the one or more TCP parameter values based on the analyzed performance metrics;
• updating the adjusted network policy by assigning the one or more TCP parameter values to an estimated best value;
• and
• sending the updated adjusted network policy to the second portion of the plurality of user devices.

An apparatus, comprising:

• a network policy device, implemented at least partially in hardware, configured to send a default network policy to a first portion of a plurality of user devices, wherein the default network policy assigns one or more TCP parameter values to a default value associated with the one or more TCP parameter values;
• wherein the network policy device sends an adjusted network policy to a second portion of the plurality of user devices, wherein the adjusted network policy assigns the one or more TCP parameter values to an adjusted value;
• a network traffic aggregator, implemented at least partially in hardware, configured to aggregate network traffic data received from the plurality of user devices, wherein the aggregated network traffic data records outcomes of download requests from the plurality of user devices;
• a performance metrics analyzer, implemented at least partially in hardware, configured to analyze performance metrics derived from the aggregated network data by comparing network traffic data values received from the first portion of user devices and network traffic data values received from the second portion of user devices;
• a TCP parameter estimator, implemented at least partially in hardware, configured to estimate a best value for the one or more TCP parameter values based on the analyzed performance metrics;
• wherein the network policy device updates the adjusted network policy by assigning the one or more TCP parameter values to an estimated best value;
• and
• wherein the network policy device sends the updated adjusted network policy to the second portion of the plurality of user devices.
