Technical Summary

This document provides a survey of transport protocols which are
designed to have a smaller bandwidth and/or delay impact on standard
TCP than standard TCP itself when they share a bottleneck with it.
Such protocols could be used for delay-insensitive "background"
traffic, as they provide what is sometimes called a "less than" (or
"lower than") best-effort service.

Working Group Summary

This document is a product of the LEDBAT WG. It has received reviews from
various WG participants. There were no controversies in the Last Call of
the document and the WG feels the document is ready for publication.

Document Quality

The algorithm that triggered this survey, which is still being worked on but
nears completion, is implemented by BitTorrent Inc. Special thanks to
