Abstract: Network traffic data associated with data requests to computer applications is collected. Specific values for specific scope-level fields are used to identify a specific scope. Traffic shares for combinations of values for specific sub-scope-level fields are determined. Based on the traffic shares, specific sub scopes are identified within the specific scope. It is determined whether customized network strategies developed specifically for the specific sub scopes are to be applied to handling new data requests that share the specific values for the specific scope-level fields and the specific combinations of values for the specific sub-scope-level fields. In response to determining that a customized network strategy for a sub scope is to be applied, estimated optimal values for network parameters in the customized network strategy are to be used by user devices to make new data requests to the computer applications.
