It has been a while since I have posted about this, and there are some updates to highlight. See below for the IPv6 and IPv4 versions of "IP Parcels and Advanced Jumbos (AJs)":
https://datatracker.ietf.org/doc/draft-templin-6man-parcels2/ https://datatracker.ietf.org/doc/draft-templin-intarea-parcels2/ The documents acknowledge that parcels are analogous to Generic Segment/Receive Offload (GSO/GRO) but taken to the ultimate aspiration of encapsulating multi-segment buffers in {TCP/UDP}/IP headers for transmission over parcel-capable network paths. They further give a name to the multi-segment buffers used by GSO/GRO, suggesting that they be called "parcel buffers" or simply "parcels". AJs are simply single-segment parcels that can range in size from very small to very large. They differ from ordinary jumbograms in several important ways, most notably in terms of integrity verification and error correction. They also suggest a new link service model that defers integrity checks to the end systems where bad data can be discarded while good data can be accepted as an end-to-end function, reducing retransmissions. Together, these documents cover all possible packet sizes and configurations that may be necessary both in the near term and for the foreseeable future for Internetworking performance maximization . Comments on the list(s) are welcome. Fred Templin
