This thread relates closely to something I posted on li this morning: Paul Vixie https://www.linkedin.com/feed/update/activity:7478870998654844928 3h
In infotech, laziness is a primary virtue. However this sometimes creates more problems than it solves. I'm thinking today of the 1500 octet packet size of Ethernet. In ten megabit over coax, 10base5, the preamble and other analog framing gave us 14400 pps for minimum sized minimum spaced packets on an unshared transmission medium and around 813 pps for maximum sized minimum spaced packets. We have clock *= 10'd many times since then, and sometimes *= 40 or *= 2. No change was made to minimum or maximum packet size, since each new Ethernet speed had to bridge to previous whenever speeds. This means pps *= factor every time, and on 400 gbit the pps is so fast we need a real time os with it's own CPU to manage the connection. Folly! We should have given sqrt(factor) to pps and sqrt(factor) to maximum packet size. If ip4 and ip6 had mtu negotiation both on the local network and the global network, everything would today be faster and cheaper including our electric power costs. It's not too late because it's never too late especially on something like this which is known to be eventually inevitable. But it would take collective will and vision, and money has changed everything. Anyway that's why RFC 9715 now exists.
