Re: [v6ops] Happy Eyeballs, v3!

Hi all,
I could not claim that I am very good at the topic (very specific to the applications domain – my experience on the network side).
I read it carefully. It was a pleasure to read – I do not remember Daft or RFC of so good quality for a long time.
It looks like nothing is forgotten. Readability is excellent. The logic is very strong and straightforward.
Justification is very clear: promote SVCB RR and QUIC.
IMHO: it is ready for adoption, if not more.

Hello v6ops,

We’ve just published a new draft for “Happy Eyeballs Version 3”, which is intended as a -bis document to RFC 8305 (which was developed in this WG). There are a few major points that needed updating:

- Describing how to incorporate SVCB / HTTPS RRs
              - Priority
              - v4/v6 hints
              - Affect on various timers, etc
              - ECH, ALPN, etc
- Describing how happy eyeballs applies to QUIC (and also TLS over TCP)

The bulk of the document is the same as RFC 8305, but updates the logic and algorithm for these changes.

Please take a look! We’d love to discuss at IETF 118 as time permits.

Best,
Tommy

Abstract:

  Many communication protocols operating over the modern Internet use
  hostnames.  These often resolve to multiple IP addresses, each of
  which may have different performance and connectivity
  characteristics.  Since specific addresses or address families (IPv4
  or IPv6) may be blocked, broken, or sub-optimal on a network, clients
  that attempt multiple connections in parallel have a chance of
  establishing a connection more quickly.  This document specifies
  requirements for algorithms that reduce this user-visible delay and
  provides an example algorithm, referred to as "Happy Eyeballs".  This
  document updates the algorithm description in RFC 8305.
