This document proposes a differentiated services per-domain behavior
(PDB) whose traffic may be "starved" (although starvation is not
strictly required) in a properly functioning network.  This is in
contrast to the Internet's "best-effort" or "normal Internet traffic"
model, where prolonged starvation indicates network problems.  In this
sense, the proposed PDB's traffic is forwarded with a "lower" priority
than the normal "best-effort" Internet traffic, thus the PDB is
called "Lower Effort" (LE).  Use of this PDB permits a network
operator to strictly limit the effect of its traffic on
"best-effort"/"normal" or all other Internet traffic.  This document
gives some example uses, but does not propose constraining the PDB's
use to any particular type of traffic.
