R&TTE
Radio & Telecommunications Terminal Equipment. The R&TTE
Directive 1999/5/EC governs the marketing and use of R&TTE
equipment. With the exception of a few categories of equipment, the
Directive covers all equipment, which uses the radio frequency
spectrum. It also covers all terminal equipment attached to public
telecommunication networks.
RT
Real Time. Real Time service is designed to meet the needs of Real
Time Variable Bit Rate (RT-VBR) like services characterized by
requirements for guaranteed rate and delay such as streaming video
or audio. These services are dynamic in nature, but offer periodic
dedicated requests opportunities to meet real-time requirements.
Because the subscriber equipment issues explicit requests, the
protocol overhead and latency is increased, but capacity is granted
only according to the real needs of the connection. Service
parameters include CIR and CT.
RTCP
RTP Control Protocol. A protocol that monitors the QoS of an RTP
connection and conveys information about the on-going session.
RTP
Real Time Protocol. An Internet protocol for transmitting real-time
data such as audio and video. RTP itself does not guarantee
real-time delivery of data, but it does provide mechanisms for the
sending and receiving applications to support streaming data.
Typically, RTP runs on top of the UDP protocol, although the
specification is general enough to support other transport protocols.
Rx
Receive
SIP
Session Initiation Protocol. An application-layer control IETF
protocol that can establish, modify, and terminate multimedia
sessions such as Internet telephony calls (VoIP). SIP can also invite
participants to already existing sessions, such as multicast
conferences. Media can be added to (and removed from) an existing
session. SIP transparently supports name mapping and redirection
services, which supports personal mobility - users can maintain a
single externally visible identifier regardless of their network
location.
