FRX/FRM 3. 3 User G uide, Rev 04

R

RIP

stands for “routing information protocol,” which provides for dynamic routing in a 
TCP/IP implementation.

Root

is the bridge determined (by implementation of the spanning tree algorithm) to be the 
lowest-cost path between points in a bridged link.

Router

is a device that receives data and routes it based on decisions made concerning the 
most desirable path.

Routing

is the process that selects the path taken by packets as they traverse the network 
between nodes.

Routing algorithm

is the precise specification of the procedure used by the nodes to determine which of 
several possible paths through the network will be taken by a packet.

RS-232C

(often called simply RS-232) is an EIA standard defining a physical and electrical 
interface for DCE/DTE connections.

RS-422

is an EIA  standard that operates in conjunction with RS-499 to specify electrical  char-
acteristics for balanced circuits (circuits with their own ground leads).

RS-449

is an EIA standard defining a physical and electrical interface for DCE/DTE connec-
tions. It has more signals than RS-232, providing such features as diagnostic and bal-
anced circuits.

RS-530

is an EIA standard that provides RS-449 capabilities in the same DB-25 connector 
used for RS-232.

S

SAP

stands for “Service Advertising Protocol” or “Service Access Point.” Service Adver-
tising Protocol allows routers and servers to exchange internetwork service infor-
mation; e.g., locations and availability of file and print servers (which connect to the 
network at Service Access Points. 

SDLC

stands for “synchronous data link control,” IBM's version of CCITT's HDLC (high-
level data link control) bit-oriented protocol.

Segmentation

is the same as Fragmentation.
