The protocol supports the use of RTP-level translators and mixers. RTP and RTCP are designed to be independent of the underlying transport and network layers. The data transport is augmented by a control protocol (RTCP) to allow monitoring of the data delivery in a manner scalable to large multicast networks, and to provide minimal control and identification functionality. RTP does not address resource reservation and does not guarantee quality-of-service for real-time services. RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services. See RadiusServers for information about various RADIUS server distributions.RTP, the real-time transport protocol.

When RADIUS is used for accounting rather than authentication and configuration, the registered UDP port is 1813 the early deployment used port 1646, which conflicted with the "sa-msg-port" service. The registered UDP port for RADIUS traffic is 1812 the early deployment of RADIUS used UDP port 1645, which conflicted with the "datametrics" service.
WIRESHARK FILTER BY PROTOCOL UDP SERIES
Merit Network awarded the contract to Livingston Enterprises that delivered their PortMaster series of Network Access Servers and the initial RADIUS server to Merit. Livingston Enterprises responded to the RFI with a description of a RADIUS server. RADIUS was originally specified in an RFI by Merit Network in 1991 to control dial-in access to NSFnet. The DIAMETER protocol is the designated successor, but RADIUS is still commonly used today. RADIUS is often used in larger Wi-Fi (wireless) networks for AAA purposes, replacing the simple shared key methods which are uncomfortable if a Wi-Fi network reaches a specific size. Its primary use is for Internet Service Providers, though it may as well be used on any network that needs a centralized authentication and/or accounting service for its workstations. RADIUS is a protocol for remote user authentication, authorization and accounting (AAA).
