A data packet transport arrangement includes a tag-based packet multiplexer and a tag-based packet demultiplexer, that utilizes an identification tag to identify packets to each of the N input channels so as to provide a logical transport channel for each of the N channels through the packet transport arrangement. The data transport arrangement thereby allows aggregating multiple communications channels into a higher bit rate link to increase bandwidth efficiency, without compromising the underlying channelized, guaranteed-bandwidth nature of the individual communication channels.
