"Faster Restart for TCP Friendly Rate Control (TFRC)", Eddie Kohler, Sally Floyd, Arjuna Sathiaseelan, Intellectual Property, 14-Jul-08. ( 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.

"The DCCP Service Code", Gorry Fairhurst, 29-Sep-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). This document updates the specification provided in RFC 4340.

"DCCP Simultaneous-Open Technique to Facilitate NAT/Middlebox Traversal", Gorry Fairhurst, 8-Oct-08. ( bytes)

This document specifies an update to the Datagram Congestion Control Protocol (DCCP), a connection-oriented and datagram-based transport protocol. The update adds support for the DCCP-Listen packet. This assists DCCP applications to communicate through middleboxes (e.g. a DCCP server behind a firewall, or a Network Address Port Translator), where peering endpoints need to initiate communication in a near- simultaneous manner to establish necessary middlebox state.

"Quick-Start for Datagram Congestion Control Protocol (DCCP)", Gorry Fairhurst, 5-Sep-08. ( bytes)

This document specifies the use of the Quick-Start mechanism by the Datagram Congestion Control Protocol (DCCP). DCCP is a transport protocol that allows the transmission of congestion-controlled, unreliable datagrams. DCCP is intended for applications such as streaming media, Internet telephony, and on-line games. In DCCP, an application has a choice of congestion control mechanisms, each specified by a Congestion Control Identifier (CCID). This document specifies general procedures applicable to all DCCP CCIDs and specific procedures for the use of Quick-Start with DCCP CCID-2 and CCID-3. Quick-Start enables a DCCP sender to cooperate with any Quick-Start routers along the end-to-end path to determine an allowed sending rate at the start and, at times, in the middle of a DCCP connection (e.g., after an idle or application-limited period). The present specification is provided for use in controlled environments, and not as a mechanism that would be intended or appropriate for ubiquitous deployment in the global Internet.
