Glossary
stands for IBM's "Systems Network Architecture."
is a method employed in bridging that avoids closed loops in the data path by deter-
mining the bridge with the lowest "path cost," which is the cost of transmitting a frame
onto the LAN.
stands for "source service access point," which is the address of the link service access
point (LSAP) from which a link protocol data unit (LPDU) originates.
is a user of the FRX/FRM device.
stands for "switched virtual circuit," which is a temporary logical association between
two subscribers connected to a network, analogous to connection by a dial-up line.
stands for "transmission control protocol," which is the Internet standard transport
layer protocol.
(sometimes abbreviated "thruput" class) reflects the line speed in bits per second.
is a MAC (see that entry) technique for data transmission that uses a "ring" configu-
ration of stations, and a "token" that is passed around the ring until taken by a station,
which inserts a packet, then retransmits the token.
is an integral (to an FRX/FRM) SNA or BSC PAD connected to a terminal.
is a physical or logical link between nodes.
is a CCITT standard defining a physical and electrical interface that is typically used
by high-speed digital carriers.
is an independent logical path between two subscribers of a packet switching network,
established for the purpose of exchanging data.
stands for IBM's "virtual telecommunications access method."
