UDP INTERACTION
UDP follows four kinds of interaction
SUPPORT FOR UNICAST, MULTICAST AND BROADCAST:
UDP gives multicast 1-to-many interaction using broadcast or a multicast. Sender uses a broadcast address as the receiver address to communicate with many applications. It is very useful for Ethernet networks.
ENDPOINT IDENTIFICATION WITH PROTOCOL PORT NUMBERS:
UDP checks an application as an endpoint. Mechanism cannot be similar as of the operating system. No common operation exist. There are multiple identifiers like job names, protocol identifiers and task identifiers.
UDP gives a set of identifiers known 'protocol ports.' It is independent of the underlying platform. Every computer using UDP gives a mapping between the protocol port number and the program checks of its operating system.
The address and protocol port specifications of an application describe the kind of interaction. To engage in a 1-to-1 communication, the application shows:
