Hot potato routing
A system in which packets cannot be buffered and therefore are simply forwarded along - like a hot potato - instead of dropped.
Has applications both on the Internet (where backbone providers do not want to incur the cost of carrying traffic meant for another providers customers and so try to dump the data off as soon as possible) and in optical networks, in which light messages cannot be stored.
