Inverse multiplexer

[1] An inverse multiplexer differs from a demultiplexer because the multiple output streams from the former stay inter-related, whereas those from the latter are unrelated.

An alternative to an inverse multiplexer is to use separate links and load sharing of data between them.

In the case of IP, network packets could be sent in round-robin mode between each separate link.

When small cargoes such as pencils are shipped overseas, they are generally not carried one at a time, but are assembled into small boxes, which are grouped into larger cartons, which go into intermodal containers, which are packed onto a container ship.

Conversely a large cargo, for example in structure relocation, may be disassembled for carriage on multiple vehicles and reassembled at the destination.
