The IESG has approved the following document: - 'Profile for Datagram Congestion Control Protocol (DCCP) Congestion ID 4: TCP-Friendly Rate Control for Small Packets (TFRC-SP) ' <draft-ietf-dccp-ccid4-05.txt> as an Experimental RFC
This document is the product of the Datagram Congestion Control Protocol Working Group. The IESG contact persons are Lars Eggert and Magnus Westerlund. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-dccp-ccid4-05.txt Technical Summary This document specifies a profile for Congestion Control Identifier 4, the Small-Packet variant of TCP-Friendly Rate Control (TFRC), in the Datagram Congestion Control Protocol (DCCP). CCID 4 is for experimental use, and uses TFRC-SP [RFC4828], a variant of TFRC designed for applications that send small packets. CCID 4 is considered experimental because TFRC-SP is itself experimental, and is not proposed for widespread deployment in the global Internet at this time. The goal for TFRC-SP is to achieve roughly the same bandwidth in bits per second (bps) as a TCP flow using packets of up to 1500 bytes but experiencing the same level of congestion. CCID 4 is for use for senders that send small packets and would like a TCP- friendly sending rate, possibly with Explicit Congestion Notification (ECN), while minimizing abrupt rate changes. Working Group Summary There has been strong support by the DCCP working group to produce this document and there is consensus to publish it. Processing the specification was delayed for a while to allow it to reflect the changes made to the TCP-Friendly Rate Control (TFRC) in RFC 5348. Document Quality The TFRC-SP mechanism has been thoroughly analyzed by ns-2 simulations. At the moment there are no other implementations of this specification.
