Re: What situations are the IP packets fragmented under?

Hi Minquan

packets are usually fragmented when the MTU (maximum transmission unit) of the network segment is smaller than the actual packet size.

When this happens the router that connects the two network segments will fragment the IP packet before transmitting the packet on to it's destination. The packets will then continue to their destination before they are reassembled into the original packet.

Re: What situations are the IP packets fragmented under?

In addition to Jon's reply whenever a router fragments the packet based on the interface MTU, it adds a pointer to the fragmented packet to let the far end know that this packet is a fragmented one and it should wait for the remaining portion of the packet and then re-assemble.
