Overview

RFC 5348, “TCP Friendly Rate Control : Protocol Specification”, is a Proposed Standard document published in September 2008 by S. Floyd, M. Handley, J. Padhye, J. Widmer. It updates RFC 4342. It obsoletes RFC 3448. The canonical text is published by the RFC Editor.

Abstract

This document specifies TCP Friendly Rate Control (TFRC). TFRC is a congestion control mechanism for unicast flows operating in a best-effort Internet environment. It is reasonably fair when competing for bandwidth with TCP flows, but has a much lower variation of throughput over time compared with TCP, making it more suitable for applications such as streaming media where a relatively smooth sending rate is of importance.

This document obsoletes RFC 3448 and updates RFC 4342. [STANDARDS-TRACK]

Abstract as published in the RFC, via rfc-editor.org.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
