RIP
See “Routing Information Protocol” on page 21.
router
A device that forwards data between networks. An IP router forwards data based on IP source and
destination addresses.
Routing Information Protocol
RIP is the routing protocol used by the routed process on Berkeley-derived UNIX systems. Many networks
use RIP; it works well for small, isolated, and topologically simple networks.
RIPng
Routing Information Protocol, new generation.
RMON
Short for remote monitoring, a network management protocol that allows network information to be
gathered at a single workstation. Whereas SNMP gathers network data from a single type of Management
Information Base (MIB), RMON 1 defines nine additional MIBs that provide a much richer set of data about
network usage. For RMON to work, network devices, such as hubs and switches, must be designed to
support it. The newest version of RMON, RMON 2, provides data about traffic at the network layer in
addition to the physical layer. This allows administrators to analyze traffic by protocol.
RPU
Remote Power Unit.
RSVP
See “Resource Reservation Setup Protocol” on page 20.
RTOS
See “Real-Time Operating System” on page 20.
S
SDL
Synchronous Data Link.
Simple Network Management Protocol
SNMP is the protocol governing network management and the monitoring of network devices and their
functions. It is not necessarily limited to TCP/IP networks. The versions have the following differences:
SNMPv1 (full): Security is based on community strings.
