Hi All, Based on the discussions at IETF 99 and on the list this update to the draft makes a number of changes:
* The Title of the draft has been changed to ‘DNS Stateful Operations’ (DSO) to reflect the fact that the TLV format is not limited to being used for signalling * The draft now updates RFC1035 * The term 'DSO session’ is used throughout for clarity * A paragraph has been added to the Introduction to discuss the use of a new format * Several terms in the Terminology section have been updated and some new ones added * Clarified the use of the words timer and timeout throughout the document * A short discussion section has been added with specific use cases * The specific mention of QUIC has been removed, the text now just describe the properties of the transport used for DSO. * The text has been updated to specify that messages must be processed in the order they were sent (not received) * A modifier Encrypted Padding TLV has been added to support padding of encrypted queries * The text describing the behaviour of middle-boxes has been updated * The set of RCODES defined in the document has been extended * Responses to DSO messages are now optional: An Acknowledgement bit has been added to the DSO data format which specifies if the DSO message requires an acknowledgement response * A section has been added to specify exactly what a client should to with the timers/timeouts when receiving a Keepalive TLV * The section on Connection sharing is now consistent with RFC7766 Regards Sara. > On 13 Sep 2017, at 10:28, internet-dra...@ietf.org wrote: > > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > This draft is a work item of the Domain Name System Operations WG of the IETF. > > Title : DNS Stateful Operations > Authors : Ray Bellis > Stuart Cheshire > John Dickinson > Sara Dickinson > Allison Mankin > Tom Pusateri > Filename : draft-ietf-dnsop-session-signal-04.txt > Pages : 32 > Date : 2017-09-13 > > Abstract: > This document defines a new DNS Stateful Operation OPCODE used to > communicate operations within persistent stateful sessions, expressed > using type-length-value (TLV) syntax, and defines an initial set of > TLVs used to manage session timeouts and termination.
