The IESG has received a request from the Transport Services WG (taps) to consider the following document: - 'Services provided by IETF transport protocols and congestion control mechanisms' <draft-ietf-taps-transports-11.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-09-09. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes, surveys, classifies and compares the protocol mechanisms provided by existing IETF protocols, as background for determining a common set of transport services. It examines the Transmission Control Protocol (TCP), Multipath TCP, the Stream Control Transmission Protocol (SCTP), the User Datagram Protocol (UDP), UDP-Lite, the Datagram Congestion Control Protocol (DCCP), the Internet Control Message Protocol (ICMP), the Realtime Transport Protocol (RTP), File Delivery over Unidirectional Transport/Asynchronous Layered Coding Reliable Multicast (FLUTE/ALC), and NACK-Oriented Reliable Multicast (NORM), Transport Layer Security (TLS), Datagram TLS (DTLS), and the Hypertext Transport Protocol (HTTP), when HTTP is used as a pseudotransport. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-taps-transports/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-taps-transports/ballot/ No IPR declarations have been submitted directly on this I-D. Please note that this Last Call period has been extended to accommodate the end of August vacation season.
