RSH
Remote Shell. A protocol that allows a user to execute commands on a remote system without having
to log in to the system. For example, RSH can be used to remotely examine the status of a number of
access servers without connecting to each communication server, executing the command, and then
disconnecting from the communication server.
RTCP
RTP Control Protocol. Protocol that monitors the
information about the ongoing session. See also RTP.
RTP
Real-Time Transport Protocol. Commonly used with IP networks. RTP is designed to provide
end-to-end network transport functions for applications transmitting real-time data, such as audio,
video, or simulation data, over multicast or unicast network services. RTP provides such services as
payload type identification, sequence numbering, timestamping, and delivery monitoring to real-time
applications.
RTSP
Real Time Streaming Protocol. Enables the controlled delivery of real-time data, such as audio and
video. RTSP is designed to work with established protocols, such as

SA
security association. An instance of security policy and keying material applied to a data flow. SAs
