A device stores a traffic management profile for satellite network traffic that provides default percentages for classes of traffic that can pass when contention for limited bandwidth exists. The device receives packets having class markings and designated for transmission over a Demand-Assigned Time Division Multiple Access (DA-TDMA) network and identifies each of the received packets as one of a transmission control protocol (TCP) packet or a non-TCP packet. The device assigns the received packets to different queues based on the class markings and the identifying as a TCP packet or non-TCP packet, and determines available transmission bandwidth for a particular time slot of the DA-TDMA network associated with the device. The device also schedules packets from the different queues based on the default percentages in the traffic management profile and the transmission bandwidth for the particular time slot.
