Re: [tsvwg] WGLC for draft-ietf-tsvwg-sctp-failover-08 - To conclude 19th November, 2014

["Becke, Martin" <[e-mail]>]

Hi all, 

I read the draft and I still think the algorithm described is functional and useful. I like the idea to introduce a potentially failed state (PF) to optimize the send process. 

I have only some questions/comments (No editorial comments, perhaps a native speaker can check the text, too):

- Perhaps the authors can give me a hint why it should be RECOMMENDED  to set the PFMR value to 0 when Quick Failover is used.  I would expect a value > 0 when it is used and 0 when it is not(!) used.   

- I think the term “multiple destinations” irritates.  Perhaps you can use “destination addresses” or “addresses” instead”.  FMPOV the use of the term “destination” in this draft is inaccurate.  In general the terms path, destination, destination address are very mixed for my feeling. Perhaps this can be rechecked.   

- “Heartbeats SHOULD be sent to PF destination(s) once per RTO. This means the sender MUST ignore HB.interval for PF destinations.”
 
This sounds strange to me. Why is SHOULD used here and what are the alternatives, when I MUST ignore HB.interval for PF destinations. I guess a rephrase of this two lines can help. 

- A link is missing in Section 5.1: [RFC6458] defines the constants SCTP_ADDR_AVAILABLE,….

Best

Betreff: [tsvwg] WGLC for draft-ietf-tsvwg-sctp-failover-08 - To conclude 19th November, 2014

TSVWG,

This is the start of a WGLC on "Quick Failover Algorithm in SCTP".
https://tools.ietf.org/html/draft-ietf-tsvwg-sctp-failover-08

This WGLC will last until Wednesday, 19th November, 2014, this includes
the period of the coming IETF meeting.

A good note to the list is "I have read this version of the draft,
and I approve (or support) its progression to RFC". The chairs
request notes to the list showing support to get a sense of the WG.

Of course, you can ask for alternate text (where you supply the
actual replacement text, or convey the meaning sufficiently to the
authors) for anywhere in the document that you find unclear or troublesome.
