The IESG has approved the following document: - 'A Survey of Lower-than-Best-Effort Transport Protocols' (draft-ietf-ledbat-survey-07.txt) as an Informational RFC This document is the product of the Low Extra Delay Background Transport Working Group. The IESG contact person is Wesley Eddy. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ledbat-survey/ 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 Mirja Kühlewind, Wesley Eddy and Mayutan Arumaithurai for their thorough reviews of the document. Personnel Rolf Winter (rolf.winter@neclab.eu) is the Document Shepherd. Lars Eggert (lars.eggert@nokia.com) reviewed the document for the IESG.
