At those size, the overhead per 64 bytes of original data would thus be 19 bytes (5B + 2bits + 6B + 14bits + 6B). That's only an efficiency of 77.11% ( 64 / (64 + 19) ).

Configuring Layer 2 Overhead Attribute in Interface Statistics

The Internet protocol suite was designed to work over many different networking technologies, each of which may use packets of different sizes. While a host will know the MTU of its own interface and possibly that of its peers (from initial handshakes), it will not initially know the lowest MTU in a chain of links to other peers. Another potential problem is that higher-level protocols may create packets larger than even the local link supports. WebJul 19, 2024 · The Ethernet MTU is fixed at 1500 bytes. This means that the largest IP packet or payload an Ethernet frame can contain is 1500 bytes.
