USER DATAGRAM PROTOCOL
[attachment=17588]
Introduction
The Internet protocol suite supports a connectionless transport protocol, UDP (User Datagram Protocol).
UDP provides a way for applications to send encapsulated IP datagrams and send them without having to establish a connection.
The UDP Header
UDP transmits segments consisting of an 8-byte header followed by the payload.
The two ports serve to identify the end points within the source and destination machines.
When a UDP packet arrives, its payload is handed to the process attached to the destination port.
