= Welcome, Agenda Bash =
*Chair 5min
*Agenda approved
= Framework status update =
*draft-ietf-fecframe-framework-14
*Ali Begen 5min
*one DISCUSS left
**concerned about interoperability and mandatory security scheme
**proposed text change to address comments
**waiting for response from AD
**AD is ok with the text
**AD (Dave Harrington): missing discussion in document: operation and management
***how
***Dave: not to ask how to pick one, but maybe add a requirement what the FEC scheme needs to add.
***Greg: This is addressed by the nature of the repair symbols
***Ali:
****1-to-1 feedback possible, 1-to-many feedback may not be impossible (addressed in FEC)
****FEC packets are not essential, if they do not work, the service is not broken
****If RTCP feedback is available, post processing to evaluate operation possible
***Dave:
****no mandating of a protocol is necessary
****Still necessary to know who does the management: application or operator?
***Ali: not defined who uses for example RTCP feedback, but it is typically application issue
***Yacoob: You may use RFC5725 (draft says RFC3550 - should be changed), but it may not be available in all operations
***Dave:
****if people want to do interoperability, they need to have recommendations. How do we get interoperability across vendors
****you may do it on FEC Framework level or on scheme level
***Ali: preferred on framework
***Vincent: Do we have to mandate a FEC scheme to make this work?
***Dave: No, do not mandate FEC scheme
*Yacoob: like the security section, will provide some small feedback on this.
*Greg: group encouraged to comment and get this approved to make move the other documents
= Simple Reed-Solomon FEC Scheme =
*draft-roca-fecframe-simple-rs-01
*Vincent Roca 5min
**no updates on core
**addition of security considerations and and operations and management
*document ready for WGLC - take it to list
*no comments
= Simple LDPC-Staircase FEC Scheme =
* draft-roca-fecframe-ldpc-01
*Vincent Roca 5min
*ready for wg-last call
*Dave: You added O&M, does it talk about management?
*Vincent: No, so it will be called "operations" only
*Yacoob: What do you mean by "does not consider RTP framing of FEC repair packets"
**Vincent: draft does not look at the details of source flow and produce additional repair packets
**Yacoob: Are the repair packets multiplexed into the RTP flow or do we have a separate flow (sequence number, etc.)
**Vincent: after FEC processing you have a modified source flow and you have one or multiple repair flows. These are not RTP flows.
**Yacoob: understood - so RTP is hidden to the network
**Yacoob: If you want to use RTP, how to do this - give me a new document to do this.
**Vincent: This discussion is in the FECFRAME document (in Operation and Management document)
**Thomas: RTP framing for some codes exist, separate FEC scheme, RTP flow for repair packets is separate from source flow, association through SDP possible
*Yacoob: Systematic or not, but do you change the RTP packet
**Vincent: all codes are systematic, but the source packet may still be modified
= RTP Payload Format for Reed Solomon FEC =
*draft-galanos-fecframe-rtp-reedsolomon
*Vincent Roca 5min
**accepted as WG item, but not visible yet - needs to be approved
**addition of section on security as well as operations and management considerations
**still needs some significant work
= WG Shutdown schedule =
*Chair 5min
*Remaining and any new FEC schemes move to AVT
*Question: Where in AVT, as four new groups
**Greg to check which AVT group
**proposed for automated reply for list that this is moved to avt
*Yacoob: What about IANA registration?
**Greg: discussed on FECFRAME document
*for new FEC schemes, put together an expert review team (include AVT and RMT)
**this should be added to the FEC FRAMEWORK document
*may be the last WG meeting
