R
Remote Authentication Dial-In User Service. A client/server security protocol created by Livingston
RADIUS
Enterprises. Security information is stored in a central location, known as the RADIUS server.
rate adaptive digital subscriber line. A transmission technology that supports adaptive transmission
RADSL
rates through the use of intelligent DSL modems, which negotiate the line rate according to line
conditions and profile specifications. Once the line rate is negotiated, the rate is locked when the line
trains. RADSL supports both asymmetric and symmetric applications on a single twisted pair
telephone line. See ADSL.
random-access memory. Volatile memory that can be read and written by a microprocessor.

read-only memory
In internetworking, the duplication of devices, services, or connections so that, in the event of failure,
redundancy
the redundant devices, services, or connections can perform the work of those that failed.
The IP address of a remote server.

Dial-In User Service
See RMON.
remote monitoring
A network computer that allows a user to log on to the network from a distant location.
remote server
See RFC.
Request for
Comments
Request for Comments. The document series, begun in 1969, which describes the Internet suite of
RFC
protocols and related experiments. Not all RFCs describe Internet standards, but all Internet standards
are written up as RFCs.
A method of connecting devices so that a series of repeaters is connected to one another by
ring topology
unidirectional transmission links to form a single closed loop. Each station on the network connects
to the network at a repeater. Compare with bus topology, daisy-chain topology, star topology, and tree
topology.
remote monitoring. MIB agent specification described in RFC 1271 that defines functions for the
RMON
remote monitoring of networked devices. The RMON specification provides numerous monitoring,
problem detection, and reporting capabilities.
read-only memory. Nonvolatile memory that can be read, but not written, by the microprocessor.
