A reminer that the WGLC is currently on-going - anyone interested in this I-D is welcome to send questions and requests for clarification within the WGLC period.
Best wishes, Gorry & Tom (DCCP WG Chairs) -------- Original Message -------- Dear DCCP WG, The Chairs would like to say sorry for the long delay in processing the I-D below, following its WGLC. We now intend to progress this. While preparing the write-up of this I-D (that will request publication as an Experimental RFC) a number of issues have been found that would best be corrected (we will send these to the list). The authors have therefore been requested to make a new revision of the I-D. The current I-D has expired, but is available at: http://tools.ietf.org/wg/dccp/draft-ietf-dccp-tfrc-voip/draft-ietf-dccp-tfrc-voip-05.txt To enable this new I-D to be as correct as possible, We wish to allow others to also ask for clarifications, and raise any issues they have. This message therfore starts a new WGLC for this I-D. This WGLC will close at midnight on: 9th October 2006. Best wishes, Gorry & Tom (DCCP WG Chairs) ---- Summary This document is a chartered item of the DCCP WG. It proposes a mechanism for further experimentation, but not for widespread deployment at this time in the global Internet. TCP-Friendly Rate Control (TFRC) is a congestion control mechanism for unicast flows operating in a best-effort Internet environment [RFC 3448]. TFRC was intended for applications that use a fixed packet size, and was designed to be reasonably fair when competing for bandwidth with TCP connections using the same packet size. This document proposes TFRC-SP, a Small-Packet (SP) variant of TFRC, that is designed for applications that send small packets. The design goal for TFRC-SP is to achieve the same bandwidth in bps as a TCP flow using packets of up to 1500 bytes. TFRC-SP enforces a Min Interval of 10 ms between data packets, to prevent a single flow from sending small packets arbitrarily frequently. Flows using TFRC-SP compete reasonably fairly with large-packet TCP and TFRC flows in environments where large-packet flows and small- packet flows experience similar packet drop rates. However, in environments where small-packet flows experience lower packet drop rates than large-packet flows (e.g., with Drop-Tail queues in units of bytes), TFRC-SP can receive considerably more than its share of the bandwidth.
