Hi, it has been a little while since I have sent an update about IP parcels but see below for a new draft version with some important updates.
This draft version now fully incorporates GSO/GRO in its API and protocol description; it can therefore be considered as a standards-track submission specification for GSO/GRO as well as for the new formats known as "IP parcels" and "advanced jumbos". This document version also touches on a pain point for multi-layered reassembly schemes; it seems that a multi-layered scheme may be difficult to orchestrate on common implementations such as the linux kernel, but there should be incentive to investigate implementation extensions and/or workarounds since the potential payoff could be considerable. Finally, experimental results have shown considerable performance benefits for allowing upper layer protocol segment sizes to exceed the path MTU and therefore invoke IP fragmentation. IP fragmentation should therefore be considered as a complimentary layer in a multi-layer scheme. Any comments can be sent to the list.

Title : IP Parcels and Advanced Jumbos Author : Fred L. Templin Filename : draft-templin-intarea-parcels-64.txt Pages : 50 Date : 2023-07-24 Abstract: IP packets (both IPv4 and IPv6) contain a single unit of transport layer protocol data which becomes the retransmission unit in case of loss. Transport layer protocols including the Transmission Control Protocol (TCP) and reliable transport protocol users of the User Datagram Protocol (UDP) prepare data units known as segments, with individual IP packets including only a single segment. This document presents new constructs known as IP Parcels and Advanced Jumbos. IP parcels permit a single packet to include multiple transport layer protocol segments as a "packet-of-packets", while advanced jumbos offer significant operational advantages over basic jumbograms for transporting truly large singleton segments. IP parcels and advanced jumbos provide essential building blocks for improved performance, efficiency and integrity while encouraging larger Maximum Transmission Units (MTUs) in the Internet.
