A novel apparatus for and a method of optimized data transmission whereby an input data stream is distributed over a plurality of physical channels within a logical channel group. Transmission of data over the channel group appears as transmission over a single logical channel having a bandwidth approximately equal to the sum of the physical channel bandwidths. The physical channels making up the logical channel group may have different bandwidth capacities. The method of data unit distribution among a plurality of physical channels generates several transmission plans for scheduling data units, which may have difference lengths, over the physical channels where the data stream is composed of data units from different sessions. A best plan according to one or more optimization criteria is selected and used for distribution of the data units. The original order of transmission of the data units can be reproduced for each data session at the receiving side without the need for additional fields or modification of existing fields of the data units.
