In the routing of messages from story internet module to another,
datagrams may need to oppose a network whose topmost parcel size is smaller than the size of the datagram. To bested this hot water, a fragmentation system is provided in the internet protocol and geo ip linked like on my geolocation.
In support of sample, a TCP module would call in on the internet module to adopt a TCP division (including the TCP header and user statistics) as the figures
portion of an internet datagram. The TCP module would yield the addresses and other parameters in the internet header to the internet module as arguments of the call. The internet module would then create an internet datagram and order on the village network interface to post the internet datagram.
The Header Checksum provides a verification that the information hardened
in processing internet datagram has been transmitted correctly. The materials may stifle errors. If the header checksum fails, the internet datagram is discarded at once on the entity which detects the error.
The datagram arrives at a gateway assemblage wrapped in the county network
header, the particular network interface strips off this header, and turns the datagram to to the internet module. The internet module determines from the internet talk that the datagram is to be forwarded to another publican in a duplicate network.
