The IESG has approved the following document: - 'DNS Stateful Operations' (draft-ietf-dnsop-session-signal-20.txt) as Proposed Standard This document is the product of the Domain Name System Operations Working Group. The IESG contact persons are Warren Kumari and Ignas Bagdonas. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dnsop-session-signal/ Technical Summary This document defines a new DNS OPCODE for DNS Stateful Operations (DSO). DSO messages communicate operations within persistent stateful sessions, using type-length-value (TLV) syntax. Three TLVs are defined that manage session timeouts, termination, and encryption padding, and a framework is defined for extensions to enable new stateful operations. Working Group Summary The working group spent a significant amount of time on this document, as it adds persistence to DNS "connections". However, after several iterations, the working group came to consensus on the document, and strong consensus to move forward. Document Quality The document is clear and easily read. It defines capabilities and provides functionality to be leveraged by other protocols. There are currently no existing implementations of the protocol. However, this work is being leveraged in another working group on DNS Service Discovery. Now that this draft is moving forward, final implementations can begin to emerge. Personnel Tim Wicinski is the Document Shepherd, Warren Kumari is RAD.
