An example method includes establishing a communication session between a first participant and a second participant, programming, via a control plane, a stream classifier which is to process packets associated with the communication session with classification logic. The method includes receiving a first packet at the stream classifier and, when the communication session requires recording, applying the classification logic at the stream classifier to route the first packet into a chosen service function path that includes a recording service function which reports media quality data to the control plane. Based on the media quality data, the classification logic is updated to cause a migration of the communication session to a new chosen service function path.
