User Datagram Protocol (UDP)
Provides the means for applications to exchange
individual packets of information over an IP network.
UDP uses a combination of protocol ports and
IP addresses to get a message from one point of the
network to another. More than one client can use the
same protocol port as long as all clients using the
port have a unique IP address. There are two types
of protocol ports: well-known and dynamically
bound. The well-known port assignments use the
ports numbered between 1 and 255. When using
dynamically bound port assignments, the
requesting applications queries the service first to
see which port it can use. Unlike TCP/IP, UDP/IP
provides very few error recovery services, making it
a fast way to deliver broadcast messages and performing
other tasks where reliability isn??™t a concern.
