In the routing of messages from story internet module to another,
datagrams may sine qua non to tour a network whose top packet largeness is smaller than the proportions of the datagram. To rout this difficulty, a fragmentation system is provided in the internet protocol and geo ip linked like on my geolocation.
For the purpose lesson, a TCP module would call on the internet module to convoy a TCP fraction (including the TCP header and user statistics) as the figures
subdivision of an internet datagram. The TCP module would afford the addresses and other parameters in the internet header to the internet module as arguments of the call. The internet module would then sire an internet datagram and style on the village network interface to forward the internet datagram.
The Span to Live is an portent of an upper fixed on the lifetime of
an internet datagram. It is decide via the sender of the datagram and reduced at the points along the way where it is processed. If the time to unexploded reaches zero in preference to the internet datagram reaches its destination, the internet datagram is destroyed.
The internet module determines that the datagram is seeking an employment program in this host. It passes the matter to the application program in feedback to a system call up, expiration the beginning
give a speech to and other parameters as results of the call.
