Viewing UDP Group Information
The UDP Group window
The User Datagram Protocol (UDP) is the piece of the TCP/IP protocol suite that
deals with getting a datagram from an application running on one host to an
application running on a different host. UDP is able to choose the correct process
on a host by delivering the datagram to a specific port. A port is nothing more
than a queue, assigned by the operating system and used by a specific process to
send and receive datagrams.
UDP uses IP as the underlying transport mechanism; as such, UDP provides
unreliable connectionless delivery service. Since the protocol does not employ
any type of acknowledgment mechanism, the sending application is not notified
of delivery problems (datagrams getting lost, duplicated, or arriving out of
order).
To open the UDP Group window from the System Group window:
1. Click the Other Groups button. The Other Groups drop-down menu displays.
2. Click on UDP Group. The UDP Group window, Figure 11-1, opens.
