WebMar 6, 2024 · Maximum Transmission Unit (MTU) 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. TCP protocol operations may be divided into three phases. Connection establishment is a multi-step handshake process that establishes a connection before entering the data transfer phase. After data transfer is completed, the connection termination closes the connection and releases all allocated resources. kouts procedure foot
