A system, method, and computer program product are provided for determining dynamic subnetworks in a communication network. In use, a plurality of network entities of a communication network is determined. Additionally, measurements of an amount of interaction between pairs of network entities of the plurality of network entities are collected. Further, at least one division characteristic is determined, and an intersection between the measurements and the at least one division characteristic is determined. Moreover, at least one border of a subnetwork of the communication network is determined, where the at least one border is based on the intersection.
