This version restructures the document to present the material in a more logical way. There are no technical changes.

Tiesel, Chris Wood, and Tommy Pauly, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, July 2020, Work in progress (draft-ietf-taps-interface-08.txt).

This version clarifies behaviour of connection groups, message framers, and the "Interactive" property for multipath connections.

Tiesel, Chris Wood, and Tommy Pauly, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, July 2020, Work in progress (draft-ietf-taps-interface-07.txt).

This version of the Transport Services API draft adds some discussion of advertising alternative addresses for multipath connections, and of connections where the initiating side is not the first to write. It better explains the model for connection property negotiation, and adds properties to signal multi-path transports and bounds on send and receive rate. It also includes a large number of minor updates, clarifications, and fixes throughout.

Tiesel, Chris Wood, and Tommy Pauly, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, March 2020, Work in progress (draft-ietf-taps-interface-06.txt).

This version version is a major update. It updates the introductory remarks; clarifies that some events might have default handlers in certain implementations, and that it's not necessarily safe ignore events; expands the examples; expands discussion of transport properties and other parameters; adds discussion of multicast; clarifies the relation between Initiate() and Preconnection objects; clarifies the behaviour of passive listen and peer-to-peer rendezvous; clarifies and role and behaviour of cloned connections and connection groups; clarifies the role of framers; expands discussion of Message Contexts; clarifies that maxLength and minIncompleteLength are used to manage buffering and are unrelated to message ordering; updates protocol-specific properties; and expands the security considerations.

Tiesel, Chris Wood, and Tommy Pauly, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, November 2019, Work in progress (draft-ietf-taps-interface-05.txt).

This version clarifies meaning of defaults; provides for reason codes for errors; provides for rate limiting of inbound connections; updates the discussion of message framers, much of which has moved to the implementation draft; adds an appendix containing convenience functions; and clarifies the relation to the Minimal Set of Transport Services for End Systems.

Tiesel, Chris Wood, and Tommy Pauly, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, July 2019, Work in progress (draft-ietf-taps-interface-04.txt).

Editorial clarifications throughout, including clarification of normative language. Clarifications around idempotent data, connection cloning, and message contexts and replies. More clearly specify defaults for message properties. Expand discussion of message contexts and message framers; specify an initial framer API.

Tiesel, and Chris Wood, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, March 2019, Work in progress (draft-ietf-taps-interface-03.txt).

This versions provides some initial usage examples. It expands the discussion of transport and connection properties, and gives each property a well-known name. The InitiateWithIdempotentSend() call is renamed to InitiateWithSend() and idempotency is specified by a message property.

Tiesel, and Chris Wood, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, October 2018, Work in progress (draft-ietf-taps-interface-02.txt).

This version expands and reorganises the discussion of Transport Properties; updates the discussion of how properties apply to Preconnections, and how Preconnections and Connections relate; updates the discussion around name resolution; and expands the discussion of connection groups. The InitiateWithIdempotentSend() action is added, along with some discussion about managing connections. A discussion of Connection State and Ordering of Operations and Events is added. Finally, Appendix C explains the Relationship to the Minimal Set of Transport Services for End Systems.

Tiesel, and Chris Wood, An Abstract Application Layer Interface to Transport Services (.txt|.pdf), Internet Engineering Task Force, July 2018, Work in progress (draft-ietf-taps-interface-01.txt).

This version reorganises the parameters and options into a new transport properties section, and makes some clarifications to the security properties. There are also some clarifications to the state machine and the ordering of events, and some updates to the text around sending and receiving partial messages.

This draft was adopted as a work item of the TAPS working group at IETF 101 in London in March 2018. In addition to a number of editorial fixes, the draft removes the ability to clone Preconnections; expands discussion of property negotiation; removes immediate acknowledgement and adds batching sends; and clarifies the response to ICMP soft errors.
