This politesse is called on nearby host-to-host protocols in an internet environment. This rules calls on adjoining network protocols to act up
the internet datagram to the next gateway or journey's end host and some
user agent details.
On the side of example, a TCP module would call in on the internet module to snitch a TCP division (including the TCP header and owner information) as the figures
subdivision of an internet datagram. The TCP module would provide 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 style on the townswoman network interface to transmit the internet datagram.
The archetypal of enterprise is that an internet module resides in each herd engaged in internet communication and in each gateway that interconnects networks. These modules parcel shared rules for
interpreting lecture fields and for fragmenting and assembling internet datagrams. In supplement, these modules (especially in gateways) have procedures in search making routing decisions and other functions.
The specific network interface creates a local network header, and attaches the datagram to it, then sends the result via the peculiar network.
