[tsvwg] TSVWG Status Summary - 15 June 2019

[Gorry Fairhurst <[e-mail]>]

Hi TSVWG'ers,

This is a request for people with topics they think it would be useful 
to be presented to the TSVWG working group at the Montreal IETF. If you 
edit a WG draft, we expect an update. Please do let us know how much 
time you think is needed, and the key points to be addressed.

If you wish to present on another topic, or another non-WG draft please 
contact and let us know what you would like to present. Please also be 
sure to discuss the topic on the tsvwg prior to this meeting.

As ever, priority, as ever will be given to drafts that have been 
discussed on the list and that are expected to benefit from WG 
discussion time.

Gorry, David and Wes
(TSVWG Co-Chairs)
