The ability to consistently support 64KB packets and thus high
throughput is potentially one of the main selling points for IPv6. I
don't believe in trying to persuade people to move to IPv6 through
differences in function. It will be a decade minimum before I consider
making use of an IPv6 feature not supported in IPv4 in an application
protocol. Performance is something else, I will encourage people to
upgrade to get faster performance.
You mean >64KB? -- 'cause IPv4 can do 64KB packets...
By 'doing' I mean, it actually works in practice with stuff bought off
the shelf without any special configuration or expertise or additional
software beyond that provided by the platform vendors.
I am aware that IPv4 was always theoretically capable of jumbo frames.
But practice has been rather different. And one of the biggest
problems we still have is that while we talk about IP everywhere, the
reality is 'IP atop IEEE link layer' and the IEEE people still insist
on supporting non IP protocols.
Problem is that most of us have ethernet hubs rather than true IP
switches. If we had real IP everywhere we could deprecate MAC
addresses.
