Let’s get the AMAs kicked off on Lemmy, shall we.
Almost ten years ago now, I wrote RFC 7168, “Hypertext Coffeepot Control Protocol for Tea Efflux Appliances” which extends HTCPCP to handle tea brewing. Both Coffeepot Control Protocol and the tea-brewing extension are joke Internet Standards, and were released on Apr 1st (1998 and 2014). You may be familiar with HTTP error 418, “I’m a teapot”; this comes from the 1998 standard.
I’m giving a talk on the history of HTTP and HTCPCP at the WeAreDevelopers World Congress in Berlin later this month, and I need an FAQ section; AMA about the Internet and HTTP. Let’s try this out!
How do you feel about the internet being “stuck” with an MTU of 1500?
This is kinda the problem with widely deployed standards like TCP/IPv4: if you have even one device out there that’s on the “old” standard, it won’t be able to talk under a hypothetical new standard like IPv6 or TCP-with-huge-packets. And there are a lot more than one device out there that would be cut off.
As I understand it, the big pipes have very large MTUs now, and the edge routers cut up the packets for further transport. That’s probably the only way we can realistically go forward.
I hope soon with ipv6 MTU discovery, as home connections get faster, the inefficiencies of a small MTU will drive offerings of dynamic/large MTUs.
