Recap - the Prague BOF

• A BOF was held in Prague
• problem statement, or "there is an interesting
  problem"
• NTP and 1588 presentations, or "the problem IS
  solvable"
• other SDOs, or "the problem is not being solved
  elsewhere"
• open mike, or "do we want to solve this problem
  here?".
• Nearly universal agreement on all four points
• However, many of those present felt that
• more modularization was required
• more focus was required
• the precise goals of TICTOC were not clear enough
• Could not achieve agreement as to charter

Today's BOF

• FOCUS ON CHARTER
• (new version available on unofficial TICTOC web
  site)
• In order to understand the charter, we need to
  understand
• what a 1588 profile is
• the relationship between TICTOC and NTP WGs
• why AD and TD and master selection is important
• the three use cases

6
Discussion

• Are the use cases clear, necessary, and
  sufficient ?
• Are the goals achievable ?
• Should TICTOC take on the NG-NTP work ?
• When should discovery work be done ?
• Is there sufficient support for the new charter ?
• How many people intend to actively participate ?
