Glossary
protocol suite
A group of protocols related to a common framework.
RARP (reverse address resolution protocol)
A protocol that translates MAC addresses to IP addresses.
ring
A network of stations that uses a circular logical topology. Data is
passed from station to station, for examination or copying, and is
finally returned to the originating station, which removes the data
it transmitted from the network.

RISC (Reduced Instruction Set Computing)
A data processing technology in which functions are performed
using the least possible number of instructions to yield very fast
processing.

RTMP (Routing Table Maintenance Protocol)
In the AppleTalk routing protocol, RTMP is a distance vector
routing protocol similar to RIP. It keeps track of hop
count/destination network range pairs. Split Horizon is
performed, but poison reverse and triggering are not. Periodic
updates are sent once every 10 seconds. Individual route lifetimes
are not kept. Instead, all routes are marked as “suspect” once every
20 seconds. If the route is not updated by the next 20 second
interval, it is marked bad. Following two or more intervals, the
route is removed from the table.
