Maximum Transfer/Transmission Unit
Maximum transmission unit defines the largest size of packets that data link can transmit without needing to fragment. For example, IP packets larger than the MTU must use IP fragmentation and rely on reassembly at the IP destination. The maximum transmission unit (MTU) of an IPv4 datagram using the default encapsulation is 1500 octets so link configurations often limit MTUs at around this value. WAN protocols like PPP sometimes set even lower MTU values. In all these cases, oversize packets are often called jumbo packets. IETF RFC 1191 describes a technique for dynamically discovering the maximum transmission unit (MTU) of an Internet path using the Don't Fragment (DF) bit in the IP header. This means that the sender can send the largest possible IP packets whilst knowing that fragmentation is unlikely.
