a desired user experience with respect to a desired maximum end to end delay e g 2 seconds the ifcs sends a stop notification input off signal to the ais when the ais receives the input off signal the ais does not accept any further data from the local transmitting user for the time being the ifcs informs the transmitting user as to whether it is sending an input off signal to the ais to thereby inform the transmitting user whether additional data will be accepted by the ais according to an exemplary embodiment the ifcs is configured to transmit a resume notification to the ais after the eed is determined to no longer exceed the threshold while the ais is not accepting data from the transmitting user after receiving the stop notification the ais is configured to resume accepting input data from the transmitting user upon receiving the resume notification the ifcs informs the transmitting user when the resume notification is transmitted to the ais according to another exemplary embodiment the ifcs is configured to cease transmitting the stop notification to the ais after the eed is determined to no longer exceed the threshold while the ais is not accepting data from the transmitting user after receiving.
