-
This version updates the Abstract and Introduction to more clearly state the benefits of the Transport Services framework, and updates the API summary to more clearly show use of the API. It expands the discussion of the use and role of Preconnection objects, preferences, provisioning domains, connection groups, and connection termination. And it explains how to disable security in the Transport Services API, when talking with legacy endpoints such as TCP servers that don't use TLS, while noting that this use is not recommended.

This is a minor updates that makes some clarifications around transport properties and multipath transport, adds a Connection.CloseGroup() action, and updates the state diagram to include the closing state.

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

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

-
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.

-
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.

-
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.

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.
