GFC
Generic Flow Control — A 4-bit field in the ATM cell
header in order to support multiplexing functions. Its
default value is ‘0000’, when the GFC protocol is not
enforced. The GFC mechanism is intended to support
simple flow control in ATM connections.
HEC
Header Error Control or Header Error Check — A
1-byte field in the cell header used for the header
error detection and correction. Due to the importance
of the information contained in the header, HEC is a
useful and important field.
ILMI
Interim Local Management Interface — Published by
the ATM Forum, this standard provides extra
diagnostic, monitoring and configuration services at
the User-to-Network Interface (UNI). It uses the Simple
Network Management Protocol (SNMP) and a MIB.
LAN Emulation (LANE)
A technique that specifies the interfaces and
protocols needed for providing LAN-supported
functionality and connectivity in an ATM Environment.
LANE allows existing LAN protocols to interoperable
with the ATM protocols, interfaces and devices.
LE_ARP
LAN Emulation Address Resolution Protocol — The
ARP used in LAN Emulation for binding a requested
ATM address to the MAC address.
LEC
LAN Emulation Client — Typically located in an ATM
end-system (for example, an ATM Module or ATM
Switch), its task is to maintain address resolution
tables and to forward data traffic. It is uniquely
associated with an ATM address.
LECS
LAN Emulation Configuration Server — A server
whose main function is to provide configuration
information to a LEC (such as the ELAN it belongs to
or its LES).
LES
LAN Emulation Server — A server that provides
support for the LAN Emulation address resolution
protocol (LE_ARP). The LECs register their own ATM
and MAC addresses with the LES. A LES is uniquely
identified by an ATM address.
link
Physical connection between two nodes in a network.
It can consist of a data communication circuit or a
direct channel (cable) connection.
MIB
Management Information Base — A data structure
that defines objects for referencing variables such as
integers and strings. In general, it contains
information regarding a network’s management and
performance, for example, traffic parameters.
