WebThe original ethernet standard also specified 14 bytes for the header, and 4 bytes for the frame check sequence. That is 18 bytes. subtract 18 from 64, and you get 46 as the minimum payload. Since then, you can add a four byte VLAN tag. So, with the VLAN tag, the minimum payload size is 42. Without the VLAN tag, the minimum payload size remains 46.

WebNov 9, 2024 · The data in an ethernet frame is the payload of an ethernet frame. Your Question 1 assumes that every layer-3 protocol is IPv4, and every layer-4 protocol is TCP, which are bad assumptions. Ethernet doesn't know or care which layer-3 protocol it carries (IPv4, IPX, IPv6, AppleTalk, etc.), so the data of the frame is the payload. WebSwitched, full-duplex Ethernet makes these considerations obsolete. However, Ethernet is built on compatibility - all physical layer variants can coexist and interact with each other. So, the minimum frame size was never changed and an ancient 10 Mbit/s half-duplex node can still work in a modern multi-gigabit network without much ado.
