The problem here is ethernet. Even the latest greatest many gigabits per second ethernet can be bridged to plain old coax based 10 Mbps ethernet.
Within the ethernet protocol there is no way to negotiate the maximum frame length between stations. So IEEE standard still has a maximum of 1500 octets for the payload.
There are some RFCs that go beyond 1500, but mostly the IETF follows the IEEE specification.
Note that the 1500 link MTU applies to ethernet (and similar link technologies). For anything else, you can have larger (or smaller) MTUs.
- akvadrako 8y agoMost network devices support jumbo frames¹, which are an IEEE standard, but they aren't the default. The point is not the IEEE standard, but what most devices are configured for. Transit operators and IXPs just don't want to configure their equipment to use jumbo frames. It's probably just a coordination problem.² [1] https://www.networkworld.com/article/2224722/cisco-subnet/jumbo-frames.html https://www.networkworld.com/article/2224722/cisco-subnet/ju...
