IP supports fragmentation, though TCP generally tries to determine the path MTU and keep its packets smaller than that for performance reasons. Fragmentation increases the datagram loss rate catastrophically. If a path has a 10% packet loss rate, fragmenting a datagram into two packets makes the datagram loss rate almost 20%. WebApr 30, 2015 · On a lot of networks, the MTU is 1500 bytes, so you can send: 1500 bytes - IP header (20 bytes) - UDP header (8) bytes = 1472 bytes for payload. As a second side point, if your UDP payload is too big, i.e. payload + IP/UDP headers exceeds the MTU, then your single call to send () would result in multiple IP fragment packets.
