PMTU
PMTU is the acronym for Path Maximum Transmission Unit.
Path Maximum Transmission Unit
Refers to the maximum size of an IP packet that can be transmitted without fragmentation along a particular network path. It’s an essential concept for ensuring efficient data transmission over networks. PMTU discovery is a process used to determine the maximum packet size that can be sent without fragmentation, which helps optimize data transfer and reduce the chances of packet loss and retransmissions.
