Maximum Transmission Unit
|
Detailed explanation-1: -MTU is the largest packet or frame size, specified in octets (eight-bit bytes) that can be sent in a packet-or frame-based network. The internet’s transmission control protocol (TCP) uses the MTU to determine the maximum size of each packet in any transmission.
Detailed explanation-2: -To a programmer or developer, the acronym MTU stands for maximum transmission unit. It’s a measurement (typically in bytes) of the largest data packet a device can accept via an internet connection.
Detailed explanation-3: -The value of MTU is especially important when bridging is used because of the different network limits. RFC 791-Internet Protocols states that all IP hosts must be prepared to accept datagrams of up to 576 bytes. The minimum MTU for IPv6 is 1280.
Detailed explanation-4: -So where did 1, 500 bytes come from? It appears that it is a legacy value originally derived from a combination of hardware limits and a need to choose a value that would play well on shared network segments, without causing too much transmission latency when busy and not bringing too much header overhead.
