For UDP mode in Figure 3-3, W7500S2E-R1 module is required to have the remote IP address
and port number to create an UDP communication. UDP mode communicate is not based on
"connection". Therefore, it does not guarantee the target device could receive the data correctly
or not. Thus, it requires an upper layer communication protocol to communicate for ensuring the
data accuracy. However, since UDP mode is a simple communication protocol, it could provide a
better communication speed due to less workload on data accuracy. In fact, UDP are not likely to
get data error in network environment under normal workload. In this operating mode, both
devices are equal, and they do not differentiate into server or client.
