Abstract
This document is intended as part of an IETF discussion about
"middleboxes" - defined as any intermediary box performing functions
apart from normal, standard functions of an IP router on the data
path between a source host and destination host. This document
establishes a catalogue or taxonomy of middleboxes, cites previous
and current IETF work concerning middleboxes, and attempts to
identify some preliminary conclusions. It does not, however, claim
to be definitive.
