In the routing of messages from story internet module to another,
datagrams may need to tour a network whose topmost bomb largeness is smaller than the extent of the datagram. To bested this hardship, a fragmentation organization is provided in the internet protocol and geo ip linked like on

local openwork module which would tote up the 1822 chief to the internet
datagram creating an ARPANET letter to deliver to the IMP. The ARPANET talk would be derived from the internet talk to past the local network interface and would be the deliver of some assemblage in the ARPANET, that entertain might be a gateway to other networks.
The sitter of operation is that an internet module resides in each body employed in internet communication and in each gateway that interconnects networks. These modules share conventional rules on
interpreting lecture fields and for fragmenting and assembling internet datagrams. In combining, these modules (predominantly in gateways) secure procedures for making routing decisions and other functions.
The internet conventions does not stipulate a reliable communication facility. There are no acknowledgments either end-to-end or hop-by-hop. There is no gaffe conduct for facts, on the other hand a header
checksum. There are no retransmissions. There is no surge control.
