Path MTU Discovery (PMTUD) is a standardized technique in computer networking for determining the maximum transmission unit (MTU) size on the network path between two Internet Protocol (IP) hosts, usually with the goal of avoiding IP fragmentation. PMTUD was originally intended for routers in Internet Protocol Version 4 (IPv4).[1] However, all modern operating systems use it on endpoints. In IPv6, this function has been explicitly delegated to the end points of a communications session.[2]
PMTUD is standardized for IPv4 in RFC 1191 and for IPv6 in RFC 1981RFC 4821 describes an extension to the techniques that works without support from Internet Control Message Protocol.
