Low Extra Delay Background Transport (LEDBAT) is an experimental
delay-based congestion control algorithm that seeks to utilize the
available bandwidth on an end-to-end path while limiting the
consequent increase in queueing delay on that path.  LEDBAT uses
changes in one-way delay measurements to limit congestion that the
flow itself induces in the network.  LEDBAT is designed for use by
background bulk-transfer applications to be no more aggressive than
standard TCP congestion control (as specified in RFC 5681) and to
yield in the presence of competing flows, thus limiting interference
with the network performance of competing flows.  This document defines 
an Experimental Protocol for the Internet community.

This document is a product of the Low Extra Delay Background Transport Working Group of the IETF.
