This version of draft-ietf-dnsop-dns-tcp-requirements includes a number of changes made in response to GENART, SECDIR, ARTART, and TSVART reviews. The notable changes are:
- added RFC 1536 as a document that this one updates - new section 2.6. Reuse, Pipelining, and Out-of-Order Processing - paragraph about tweaking parameters to deal with TIME_WAIT state is now much more conservative. i.e. for experts only. - new section 4.5. Defaults and Recommended Limits talks about recommended values for connection limits, timeouts, etc. DW > On Oct 13, 2021, at 4:21 PM, [email protected] 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 Transport over TCP - Operational Requirements > Authors : John Kristoff > Duane Wessels > Filename : draft-ietf-dnsop-dns-tcp-requirements-13.txt > Pages : 33 > Date : 2021-10-13 > > Abstract: > This document updates RFC 1123 and RFC 1536.
