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. Share.
