WebA datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a … WebIn a datagram environment an application transmits a data packet into the network using the destination IP address. Routing algorithms within each node establish a route to the next node by the use of metrics such as hop count, delay, bandwidth, etc. There is no formal call setup and this procedure resembles a postal system.

WebIP will then look at the packet header to see the protocol number, and it will send the packet payload to the correct transport protocol (TCP, UDP, etc.). The transport protocol will then send the datagram payload to the application registered to it (TCP and UDP use ports for this, other transport protocols may do something else).
