Sender RTT Estimate Option for the Datagram Congestion Control Protocol
RFC 6323, “Sender RTT Estimate Option for the Datagram Congestion Control Protocol”, is a Proposed Standard document published in July 2011 by G. Renker, G. Fairhurst. It updates RFC 4342, RFC 5622. The canonical text is published by the RFC Editor.
Abstract
This document specifies an update to the round-trip time (RTT) estimation algorithm used for TFRC (TCP-Friendly Rate Control) congestion control by the Datagram Congestion Control Protocol (DCCP). It updates specifications for the CCID-3 and CCID-4 Congestion Control IDs of DCCP.
The update addresses parameter-estimation problems occurring with TFRC-based DCCP congestion control. It uses a recommendation made in the original TFRC specification to avoid the inherent problems of receiver-based RTT sampling, by utilising higher-accuracy RTT samples already available at the sender.
It is integrated into the feature set of DCCP as an end-to-end negotiable extension. [STANDARDS-TRACK]
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.
