Network-Protocols

Network protocols define how computers communicate across a network. This section will collect articles about protocols containing short descriptions, infos about the used Network-Ports, references to the official standards and how each protocol is used in FRITZ!OS. See also the TCP-IP and OSI protocol layer models and the Network-Ports.
