Web30 aug. 2024 · The router is expected to send "ICMP Fragmentation Needed" packet, allowing the sending host to account for the lower MTU on the path to the destination host. The sending side will then reduce its estimate of the connection's Path MTU (Maximum Transmission Unit) and re-send in smaller segments.This process is called PMTU-D …
WebIP Fragmentation processing at a Router The simplest approach from the end-system point of view is not to worry about the MTU size. In this simple approach, the sender simply has to ensure that each packet is less than the MTU of the link on which it is sent.
