Datagram Congestion Control Protocol WG (dccp)

Monday, November 10 at 1530-1730
================================

CHAIR: Aaron Falk <falk@isi.edu>	


AGENDA:

==============================================================

As we are planning to have a working group last call (WGLC) after
IETF-58 for the spec, CCID-2, and CCID-3, this meeting is the time to
raise any showstoppers.  We'll spend most of the meeting discussing
changes that occurred to the spec as a result of the reviews we held
over the summer.

==============================================================

0. Agenda bashing

1. WG management stuff

2. Open issues that need to be resolved before WGLC

   * # NDP -- keep it? drop it? reduce it to 1 bit?

   * How to deal with Data Dropped requirements, such as "reduce send
     rate by 1 packet per RTT", in TFRC?

   * ECN-Capable should fall back to non-ECN-Capable if the first
     ECN-Capable packet is dropped (probably by a middlebox)

   * Remove Identification and Challenge?

3. Review of fixes for problems that were identified in design review

   * Partial checksums

   * Data Dropped

   * Mobility

   * Complexity (CCID 3-Thin)

   * Checksum type (Internet vs. HMAC/UMAC/whatever)

   * Sequence number security

4. CCID-3 Thin discussion, hum on making it a wg product

5. Hum on readiness for last call (modulo discussion on items 2 & 3)
