MTUs - Was: Strange public traceroutes return private RFC1918 addresses
Ok, I know that this is getting away from the original thread, but I've always wondered this...
Why is the MTU on Ethernet 1500 bytes? I have looked through various docs (eg IEEE Std 802.x) and can find where maxUntaggedFrameSize is listed as 1518 octets, but there is no mention of why this was chosen. I know where the minimum frame size comes from (CSMA/CD and propagation times, etc), but the maximum frame size number sounds fairly arbitrary.
