FDDI
FDDI. See Fiber Distribution Data Interface (FDDI).
FESA. See Fast Ethernet ServerNet adapter (FESA).
Fiber Distribution Data Interface (FDDI). An emerging standard for a network technology
based on fiber optics. FDDI specifies a 100-mbps data rate using 1300-nanometer light
wavelength, and limits networks to approximately 200 km in length, with repeaters
every 2 km or less. The access control mechanism uses token-ring technology.
File Transfer Protocol (FTP). The Internet standard, high-level protocol for transferring files
from one machine to another. Usually implemented as application level programs, FTP
uses the TELNET and TCP protocols. The server side requires a client to supply a
login identifier and password before it will honor requests.
filter. In EMS, a file containing a list of criteria against which incoming event messages can
be compared. The messages are allowed to pass (all criteria met) or not pass (one or
more criteria failed). In the ServerNet LAN Systems Access (SLSA) subsystem (for
NonStop S-series systems and Integrity NonStop systems), filters are logical entities
which allow frames received from the LAN to be sorted and delivered to a client. In the
SLSA subsystem, filters replace the PORT objects used in K-series systems in the
sense that filters are the final destination for data received from the LAN.
FINGER. A protocol providing a method for retrieving status information about one or all the
users on a particular system.
fixed structure. In DSM programmatic interfaces, a multifield structure declared for the
value of a simple token. Fields cannot be added to fixed structures in later RVUs.
Compare extensible structure.
forwarding distributor. An EMS distributor process that sends selected event messages to
an EMS collector on another network node. See also distributor.
FTP. See File Transfer Protocol (FTP).
full-duplex mode. The communication mode in which data can be simultaneously
transferred in both directions. In the Session Layer, no data token is needed.
G4SA. See Gigabit Ethernet 4-port ServerNet adapter (G4SA).
gateway. A special-purpose, dedicated computer that attaches to two or more networks and
routes packets from one to the other. In particular, an Internet gateway routes IP
datagrams among the networks to which is connected. Gateways route packets to
other gateways until they can be delivered to the final destination directly across one
physical network. The term is loosely applied to any machine that transfers information
from one network to another, as in “mail gateway.”
Gateway-to-Gateway Protocol. The protocol core gateways used to exchange routing
information, GGP implements a distributed shortest path routing computation. Under
