The IESG has approved the following document: - 'Sender RTT Estimate Option for DCCP' (draft-ietf-dccp-tfrc-rtt-option-06.txt) as a Proposed Standard This document is the product of the Datagram Congestion Control Protocol Working Group. The IESG contact person is Wesley Eddy. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-dccp-tfrc-rtt-option/ Technical Summary The document describes problems in the current DCCP CCID-3 and CCID-4 receiver-based algorithm for estimating round-trip time, and proposes an enhancement to round-trip time evaluation by using a new Sender round-trip time estimate DCCP option. With the option, it is possible to measure RTT at the sender, and communicate the measured value to receiver, which results in more reliable RTT samples. Working Group Summary The document is a product of the DCCP WG, receiving sufficient review along its preparation. There were no controversies in WG Last Call, and the WG is in agreement to publish this document. Document Quality The document is based on observations from a real DCCP implementation on Linux kernel, and its authors are closely familiar with the implementation. The document reviewers include one of the authors of the original DCCP specification. Personnel Document shepherd is Pasi Sarolahti (pasi.sarolahti@xxxxxx). Responsible Area Director is Wesley Eddy.
