"Faster Restart for TCP Friendly Rate Control (TFRC)", Eddie Kohler, Sally Floyd, Arjuna Sathiaseelan, 19-Nov-07. ( bytes)

TCP-Friendly Rate Control (TFRC) is a congestion control mechanism for unicast flows operating in a best-effort Internet environment. This document introduces Faster Restart, an optional mechanism for safely improving the behavior of interactive flows that use TFRC. Faster Restart is proposed for use with TFRC and with TFRC-SP, the Small Packet variant of TFRC. We present Faster Restart in general terms as a congestion control mechanism, and further discuss Faster Restart for Datagram Congestion Control Protocol (DCCP) Congestion Control IDs 3 and 4.

"RTP and the Datagram Congestion Control Protocol (DCCP)", Colin Perkins, 22-Jun-07. ( bytes)

The Real-time Transport Protocol (RTP) is a widely used transport for real-time multimedia on IP networks. The Datagram Congestion Control Protocol (DCCP) is a newly defined transport protocol that provides desirable services for real-time applications. This memo specifies a mapping of RTP onto DCCP, along with associated signalling, such that real-time applications can make use of the services provided by DCCP.

"TCP Friendly Rate Control (TFRC): Protocol Specification", University London, Sally Floyd, Jitendra Padhye, Joerg Widmer, Intellectual Property, 12-Apr-08. ( bytes)

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. (This Internet-Draft is also available in PDF format [ bytes].)

"Datagram Transport Layer Security (DTLS) over the Datagram Congestion Control Protocol (DCCP)", Thomas Phelan, Intellectual Property, 14-Apr-08. ( bytes)

This document specifies the use of Datagram Transport Layer Security (DTLS) over the Datagram Congestion Control Protocol (DCCP). DTLS provides communications privacy for datagram protocols and allows client/server applications to communicate in a way that is designed to prevent eavesdropping and detect tampering or message forgery. DCCP is a transport protocol that provides a congestion-controlled unreliable datagram service.

"The DCCP Service Code", Gorry Fairhurst, 22-Apr-08. ( bytes)

This document describes the usage of Service Codes by the Datagram Congestion Control Protocol, RFC 4340. It motivates the setting of a Service Code by applications. Service Codes provide a method to identify the intended service/application to process a DCCP connection request. This provides improved flexibility in the use and assignment of port numbers for connection multiplexing. The use of a DCCP Service Code can also enable more explicit coordination of services with middleboxes (e.g. network address translators and firewalls). It updates the specification provided in RFC 4340.

"Profile for Datagram Congestion Control Protocol (DCCP) Congestion ID 4: TCP-Friendly Rate Control for Small Packets (TFRC-SP)", Sally Floyd, Eddie Kohler, 9-Feb-08. ( bytes)

This document specifies an experimental 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 experimental 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.

"DCCP Simultaneous-Open Technique to Facilitate NAT/Middlebox Traversal", Gorry Fairhurst, Gerrit Renker, 18-Feb-08. ( bytes)

This document specifies an update to the Datagram Congestion Control Protocol (DCCP), a connection-oriented and datagram-based transport protocol. The update assists DCCP applications which need to communicate through one or more middleboxes (e.g. Network Address Translators or firewalls), where establishing necessary middlebox state requires peering endpoints to initiate communication in a near-simultaneous manner.
