UDP – User Datagram Protocol Transport protocol for data traffic between network-capable devices (servers, computers, etc.) in IP-based networks. Data transmission used in almost all operating systems and is part of the IP protocol for the Internet. For data traffic, a connec- tion is not necessary between the devices. UDP is a limited-reliability, insecure and unprotected transfer protocol, as no mechanisms are provided for this. In return, UDP uses less transport management data (overhead), thereby creating a lower additional data volume and is char- acterised by a lower latency time. In contrast to TCP, UDP has a reduced range of functions: • Transport service • Multiplexing connections • Error handling • UDP is used in voice transmission, as a low latency time is required.UMTS – Universal Mobile Telecommunications System -> 3G (UMTS)
