Subject: [Stackevo] more Post-PLUS drafts

hi Ted, all,

There are two other post-PLUS BoF drafts that people who are interested in PLUS should be aware of, as well:

https://tools.ietf.org/html/draft-trammell-plus-statefulness defines a minimal, transport-independent state machine for stake-keeping middleboxes, and a set of abstract signals for driving this state machine, as a replacement for TCP flags in transport protocols with encrypted headers, as foreseen in PLUS. This is (IMO) the absolute minimum amount of signaling necessary in the path layer. This is on the agenda (in the parking lot) for the QUIC meeting in Seoul.

https://tools.ietf.org/html/draft-trammell-plus-abstract-mech is a mostly-complete description of the abstract mechanisms for signaling described in my slides in the PLUS BoF.

These two drafts together are background for a PLUS protocol design, which we intend to undertake between Seoul and Chicago. One of the things we learned from the PLUS BoF is that bits on the wire are easier to argue for or against than abstract mechanisms (which can be discussed with both unrealistic optimism and pessimism, sometimes at once), so we will make no attempt at another WG forming BoF until we have bits on the wire.

Anyone interested in helping with this effort, let us know.

Cheers,

Brian
