Reliable Multicast Transport
57th IETF, Vienna
Monday, July 14th
15:30 - 16:15
=====================

Opening Remarks
Chairs
======================
- Charter was updated:
   * removed TRACK as per WG consensus
   * GRA is still in, but to be discussed (see next)
- GRA discussion: no interested party answered to the call for
  editors/requirements issued after the last IETF. The proposal is to
  discontinue the GRA work at this time. To be decided on the mailing
  list.

NACK Oriented Reliable Multicast (NORM) Update
Joe Macker for Brian Adamson
draft-ietf-rmt-pi-norm-07
draft-ietf-rmt-bb-norm-06
==============================================

NORM BB updated 06 to 07
- http://norm.pf.itd.nrl.navy.mil has open source
- changes to make doc more compliant with TFMRC

PI doc updated from 05 to 06
- modularized
- Vincent Roca has provided feedback. In particular a header extension
  options is currently being considered to coordinate with the FLUTE spec.
- added congestion control fields
- Next steps, open source will continue to mature
  further experimentations and simulations will be performed

- Need to decide whether we want a new WG last call for the NORM
  drafts, or just go to the IESG.
- Need to solve the header extension and FLUTE issue.

FLUTE, File Delivery over Undirectional Transport
Tony Paila
draft-ietf-rmt-flute-00
==========

- 00 WG draft, derived from FDALC individual submission
- FDALC specify a particular application (usage profile) of ALC for
  file delivery over unidirectional links
- Toni is editor, added 3 new authors
- believes that new draft meets requirements from last meeting
- Proceed providing updates:
  * FDT content, XML schema from FDT syntax,
  * FDT encap streamlined, cross checked with ALC/LCT RFCs
  * how to use multiple channels, etc
  * how to describe file delivery session using SDP is now info chapter
  * receiver operation is now informational chapter
  * security considerations elaborated further
- discussion on whether part of the SDP section should be normative
  instead. Lorenzo to provide comments on this.
- propose to hold last call in September and maybe add this a charter
  milestone.
- two genetically independent implementations to be ready by
  November with some interop testing, at least one will be open source

PGMCC Update
Gianluca Iannaccone
draft-ietf-rmt-bb-pgmcc-02
====================

Security considerations
One issue addressed: Session hijacking
- session hijacking solved out authentications
- can drive the sender to flood the network
- breaks the election mechanism
The rest is transport protocol responsibility
- authentication
- deal with the denial of service problem

Recommendations
- PGMCC sender should compare ACK stream with reported
  loss rate and RTT info reports to prevent DOS attacks
- if violation mark acker has ineligible
- believer ready for last call

Lorenzo: TFMCC and PGMCC both look like they are ready
  for last call...need to check with TFMCC authors
Lorenzo: discussed with Allison about potential outside
  reviews of TF/PGM CC drafts form people not involved
  with them...would be an additional step before submission
  to the IESG
Pullman: have done some experiments with TFMCC and it
  appears to work well.
