RE: [EXTERNAL] Re: Transmission of IPv6 Jumbograms as Atomic Fragments

Brian, I came through the supercomputer lab at NASA Ames in Mt View CA in 1996/7
where HiPPI was heavily used. I didn't spend much time there, but enough to get a
rough read that large packets are plausible.

At some time not long after that, I had the good fortune to meet Dave Borman and
asked him about RFC2675 with a "YMBK" pre-disposition toward the concept. Dave
assured me that the document was serious, and I do not see evidence that it has
been deprecated.

So, do I know of any such mega-links? Not offhand, but AFAICT RFC2675 is still part
of the IPv6 architecture and needs to be honored as such.

Thanks - Fred
