Glossary 703
routing table A table kept in a router or other internetworking mechanism
that maintains a record of only the best possible routes to certain network
destinations and the metrics associated with those routes.
RP Route Processor: Also known as a supervisory processor, a module on
Cisco 7000 series routers that holds the CPU, system software, and most of
the memory components used in the router.
RSP Route/Switch Processor: A processor module combining the functions
of RP and SP used in Cisco 7500 series routers. See also: RP and SP.
RTS Request To Send: An EIA/TIA-232 control signal requesting permission
to transmit data on a communication line.
S reference point ISDN reference point that works with a T reference
point to convert a 4-wire ISDN network to the 2-wire ISDN network needed
to communicate with the ISDN switches at the network provider.
sampling rate The rate at which samples of a specific waveform amplitude
are collected within a specified period of time.
SAP 1) Service Access Point: A field specified by IEEE 802.2 that is part of
an address specification. 2) Service Advertising Protocol: The Novell NetWare
protocol that supplies a way to inform network clients of resources and services
availability on network, using routers and servers. See also: IPX.
SCR Sustainable Cell Rate: An ATM Forum parameter used for traffic
management, it is the long-term average cell rate for VBR connections that
can be transmitted.
SDLC Synchronous Data Link Control: A protocol used in SNA Data-Link
layer communications. SDLC is a bit-oriented, full-duplex serial protocol
that is the basis for several similar protocols, including HDLC and LAPB. See
also: HDLC and LAPB.
seed router In an AppleTalk network, the router that is equipped with
the network number or cable range in its port descriptor. The seed router
specifies the network number or cable range for other routers in that network
section and answers to configuration requests from nonseed routers
on its connected AppleTalk network, permitting those routers to affirm or
modify their configurations accordingly. Every AppleTalk network needs at
least one seed router physically connected to each network segment.
