Low Extra Delay Background Transport
RFC 6817, “Low Extra Delay Background Transport”, is an Experimental document published in December 2012 by S. Shalunov, G. Hazel, J. Iyengar, M. Kuehlewind. The canonical text is published by the RFC Editor.
Abstract
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.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
