Thank you - Fred
1. IP Parcels - Fred Templin
draft-templin-intarea-parcels - 15 min
* 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.
* Add a jumbo payload option and not 0 in payload length.
* IP parcels are based on IP Jumbograms, it can be supported in IPv6 and
IPv4.
* Can we adopt the document as a WG Item ?
* JCZ: need support on the list
* Lars: how can this increase performance?
* Fred: it reduced the numbers of interrupts and the overhead of the
parcel.
* Lars: We already do it on the ends, we have already these efficiencies.
* Fred: There is no additional efficiency over GSO?
* 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.
* Luigi: How will the network have the ability to know how to use the
parcel.
* 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.
* Luigi: What happens if links in the middle suport IP Parcels but the
end doesn't.
* 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.
