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 |
