According to one configuration, a network environment includes multiple communication devices and a data flow manager (such as associated with a communication gateway). During operation, the data flow manager receives multiple data flows from the multiple communication devices, each of which conveys data associated with a respective communication device in a network environment. The data flow manager controls conveyance of the multiple data flows through the communication gateway. In response to detecting occurrence of an alarm event in the network environment, the data flow manager modifies an original priority of conveying the classified data flows through the communication gateway. The modified priority provides increased bandwidth accommodating conveyance of a corresponding data flow associated with the alarm event through the communication gateway.
