Re: [tcpPrague] Draft L4S deliverables list

["De Schepper, Koen (Nokia - BE)" <[e-mail]>]

Hi Bob,

I want to help on 1, 2 and most of the topics in 3 mainly in the scope of 4, with implementations for Linux.

Koen.

Subject: [tcpPrague] Draft L4S deliverables list

Folks,

Here's the table of potential deliverables that I presented in Buenos Aires. I've started to add volunteer's names.
Pls continue...

Each should probably be divided into implementation and drafting the spec, but let's assume any volunteer will do both/either.

Description

Draft(s)

Volunteers

Target WG

1)

L4S identifier

draft-briscoe-tsvwg-ecn-l4s-id

authors on draft

tsvwg?

2)

The DualQ AQM

draft-briscoe-aqm-dualq-coupled

authors on draft

aqm?


3)

Scalable Transport

3-1)

Fall back to Reno/Cubic on loss

Linux / tcpm

3-2)

TCP ECN Feedback

draft-ietf-tcpm-accurate-ecn

authors on draft

tcpm

3-4)

Scaling TCP's Congestion Window for Small Round Trip Times

Bob Briscoe, Marcelo Bagnulo Braun

tcpm?

3-5)

Reduce TCP / SCTCP / TCP Prague RTT-dependence

tcpm?

3-6)

Smooth ECN feedback over flow's RTT, not RTT hard-coded for DC

tcpm?

3-7)

Fall back to Reno/Cubic if classic ECN bottleneck detected

tcpm?

3-8)

Faster-than-additive increase

Marcelo

tcpm?

3-9)

Less drastic exit from slow-start

Marcelo, Bob

tcpm?


4)

“TCP Prague” (for the Internet)

tcpm?

5)

DCTCP bis (for data centres - may be the same as TCP Prague)

draft-ietf-tcpm-dctcp (bis)

tcpm?

6)

"SCTP Prague"

tcpm/tsvwg?

7)

“RMCAT Prague”

rmcat?


Notes:
A line can be drawn somewhere around 3-7) to indicate that everything above is an essential safety feature (preventing starvation etc), while everything below (up to 3-9) is a performance improvement.

4,5,6) are essentially wrap-ups of the relevant elements from 3-1) to 3-9) for each different transport
7) might require one draft for Nada, one for SCREAM, etc or it might be possible to describe one simple delta for all RMCAT approaches.

Whether we need all the bitty pieces 3-1) to 3-9) or whether we should go straight for the wrap-up solutions, is up for discussion.


Bob
