  7. CCID-3 Thin poll • Should DCCP take draft-ietf-dccp-ccid3-thin-00.txton as a new deliverable? • How hard is this? • Pretty simple • Keep thinking about how to express this task as a possible future work item • Consider making CCID3-thin an appendix to spec as an existence proof of simplicity • Why not: multiple profiles all requiring state machine changes is BAD • May be premature, consider CCID-4 future IETF-58 Minneapolis 7

  8. Work to be done Can you send slightly above congestion control allowed rate? (up to twice allowed rate) Possibly a work item in tsvwg During slow start or after idle, are you allowed to send at more than twice the current rate? Clearly research TFRC w/variable packet sizes Expected in tsvwg, on Sally’s list IETF-58 Minneapolis 8

  9. Moving forward, a poll • How many are following the working group (reading list, drafts…)? • Of those, how many are planning on going to Korea? IETF-58 Minneapolis 9
