Product overview
User Datagram Protocol (UDP)
UDP is connectionless transport protocol. It provides no control mechanism when exchanging data between
sender and receiver. This results in a higher processing speed than, for example, TCP. Checking whether or
not the telegram has arrived must be carried out by the higher-level protocol.
Internet Control Message Protocol (ICMP)
It is used by end devices, to exchange information about the current status of the internet protocol.
Address Resolution Protocol (ARP)
Performs conversion between the IP addresses and MAC addresses.
BootP
The BootP protocol allows the TCP/IP address to be set or altered, by addressing the network device with its
MAC-ID.
