In networking, maximum transmission unit (MTU) is a measurement representing the largest data packet that a network-connected device will accept. Imagine it as being like a height limit for freeway underpasses or tunnels: Cars and trucks that exceed the height limit cannot fit through, just as packets that exceed the MTU of a network cannot pass through that network.

The Maximum Transmission Unit (MTU) of a network link is the maximum size of packet that can be sent across that network link. It is common for all links in a network to be configured with the same MTU to reduce the need to fragment packets as they traverse the network, which can significantly lower the performance of the network

Most networks have links with an MTU of 1,500 bytes, but some networks support MTUs of 9,000 bytes
