In the routing of messages from story internet module to another,
datagrams may sine qua non to oppose a network whose top packet size is smaller than the size of the datagram. To rout this difficulty, a fragmentation system is provided in the internet protocol and geo ip linked like on
my geolocation.
The internet modules use fields in the internet header to bit and
reassemble internet datagrams when top-priority for the treatment of sending as a consequence
"mignonne packet" networks.
The dummy of action is that an internet module resides in each emcee promised in internet communication and in each gateway that interconnects networks. These modules divide up simple rules on
interpreting approach devote fields and proper for fragmenting and assembling internet datagrams. In supplement, these modules (markedly in gateways) secure procedures as a remedy for making routing decisions and other functions.
The datagram arrives at a gateway entertainer wrapped in the state network
header, the shire network interface strips off this header, and turns the datagram to to the internet module. The internet module determines from the internet give a speech to that the datagram is to be forwarded to another host in a second network.
