Dear Spencer, all, I just had a look into the IETF111 PANRG recordings and found the presentation about Path Selection for Multiple Paths very refreshing. It would be good to have a place where multipath challenges and solutions can be consolidated in IETF. The challenges you brought up in your presentation are related to multipath transport layer approaches like MP-TCP/QUIC/SCTP/DCCP, but also (partly) to any other approach on layers different to this, e.g. GRE bonding (RFC8157) etc. pp. That's why I appreciated your updated presentation title "Path Selection for Multiple Paths" instead of "Path Selection for Multiple Paths in QUIC". The individual topics you raised (and I expanded) - scheduling - reordering - path estimation by CC or other means - sequencing - loss detection and handling - nested or concatenated CC - e.g. QUIC over MP-DCCP (3GPP ATSSS) and also their possible interworking is an interesting research area. In the MP-DCCP development we are quite advanced in the identification of this challenges and for some of them we are providing quite efficient solutions. Some of them are documented as part of the MP-DCCP protocol draft in TSVWG others like scheduling, reordering and fast packet loss detection are provided to ICCRG or published in academic paper. I encourage and invite people interested in that research area to look into https://multipath-dccp.org as a nice little playground. The provided MP-DCCP Linux reference implementation there provides at least initial support for all of the topics mentioned above. So full support from my side, please go ahead with this work! Is your plan now to shift your work on draft-dawkins-quic-multipath-selection to PANRG? And maybe change the title of your current draft to a more general title like for example "Path Selection in Multipath transport"? Btw. it's my first post to the PANRG mailing list 😊 Br Marku
