RARP
Reverse Address Resolution Protocol.
This is the Internet protocol a diskless host uses to find its Internet address at start-up.
RARP maps a physical (hardware) address to an Internet address. See ARP.
Remote file CoPy, a Unix program for copying files to/from a remote host.
RDBMS
Relational DataBase Management System
RED
Random Early Detection
repeater
A device which retransmits electrical signals from one cable to another without making routing decisions or providing packet filtering. Repeaters are often used to extend a cable without violating electrical or timing limits of the signals on the cable. They are also used to protect a cable from electrical failures on other cables. See bridge.
REU

RFC
Request For Comments. The document series, begun in 1969, which describes the Internet suite of protocols and related experiments. Not all (in fact very few) RFCs describe Internet standards, but all Internet standards are written up as RFCs. The NETS keeps copies of many RFCs in /fs/projects/nets/rfc.

RGMP
Router Group Management Protocol
RIP
Routing Information Protocol described in RFC 1058. A popular old simple IP routing protocol. Most network devices that can route IP, including almost all Unix hosts, can exchange routing information with other network devices using RIP.
RK
Resource Kit (Microsoft)
rlogin
A Unix program which allows users of one machine to log into other UNIX systems (for which they are authorized) and interact as if their terminals were connected directly. Similar to telnet.

RMON
Remote network MONitoring. See RFC 1271.

router
A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this it uses algorithms to choose the best route based on several criteria known as "routing metrics." See gateway, bridge, repeater and OSPF.
RP
Route Processor; Rendezvous Point
RPC
Remote Procedure Call. An easy and popular paradigm for implementing the client-server model of distributed computing. A request is sent to a remote system to execute a designated procedure, using arguments supplied, and the result returned to the caller. There are many variations and subtleties, resulting in a variety of different RPC protocols.
