Hi Fred, Thanks for the review. The minutes have been corrected accordingly.
https://datatracker.ietf.org/meeting/113/materials/minutes-113-intarea-04 Best, Juan Carlos & Wassim From: Templin (US), Fred L <fred.l.temp...@boeing.com> Date: Friday, April 1, 2022 at 11:19 AM To: Juan Carlos Zuniga (juzuniga) <juzun...@cisco.com>, int-area@ietf.org <int-area@ietf.org> Subject: RE: IntArea WG Minutes IETF 113 Juan Carlos & Wassim – see below for corrections to the minutes: Thank you - Fred 1. IP Parcels - Fred Templin draft-templin-intarea-parcels - 15 min o Fred: packet is the retransmission unit in case of lost. Have a packet of packets. >> This is incorrect; what I said was that a “segment” is the retransmission >> unit in case of loss, >> and a Parcel may contain multiple segments. In that sense, it is a >> packet-of-packets. o Add a jumbo payload option and not 0 in payload length. o IP parcels are based on IP Jumbograms, it can be supported in IPv6 and IPv4. o Can we adopt the document as a WG Item ? o JCZ: need support on the list o Lars: how can this increase performance? o Fred: it reduced the numbers of interrupts and the overhead of the parcel. o Lars: We already do it on the ends, we have already these efficiencies. o Fred: There is no additional efficiency over GSO? o Fred: The end systems see the same efficiency that we see with GSO GRO TCP segment offload. >> Because a Parcel may contain multiple segments, end systems will see better >> performance >> than just using GSO/GRO when the Parcel is sent intact over links that have >> sufficient MTU. >> Also, GSO/GRO are not and cannot be standardized, whereas IP Parcels can be. o Luigi: How will the network have the ability to know how to use the parcel. o Lars: We start to send regular IP packets and then you send the probe. If the probe succeeds you can then start using parcels. >> It was me (Fred) who provided this answer, and not Lars. o Luigi: What happens if links in the middle suport IP Parcels but the end doesn't. o Lars: Then, it will be like regular IP packets. >> Again, it was me (Fred) and not Lars who provided the answer. But, it was >> not made clear >> that there are two kinds of Parcel-capable links – edge network links that >> support Parcels >> natively, and the OMNI link in the middle of the network that supports >> Parcels through >> the OMNI Adaptation Layer. There is no need for links in the middle of the >> network that >> support Parcels natively.
