This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment the transmitter removes duplicate data packets from a queue after a second channel such as a dedicated channel is established. In an alternate embodiment sequence numbers are assigned to data packets allowing the receiver to identify duplicate packets and ignore the duplicates.
