601
Layer A subdivision of the Open System Interconnection (OSI) architecture,
constituted by subsystems of the same rank.
LDAP See Lightweight Directory Access Protocol.
Lightweight
Directory Access
Protocol (LDAP)
A set of protocols for accessing information directories. LDAP is based on the
standards contained within the X.500 standard, but is significantly simpler.
And unlike X.500, LDAP supports TCP/IP, which is necessary for any type of
Internet access to a directory server.
LLC See Logical Link Control Procedure.
Local Area
Network (LAN)
A non-public data network in which serial transmission is used for direct data
communication among data stations located on the user's premises.
Logical Link
Control (LLC)
Procedure
In a local area network (LAN) or a Metropolitan Area Network (MAN), that
part of the protocol that governs the assembling of data link layer frames
and their exchange between data stations, independent of how the
transmission medium is shared.
MAC See Media Access Control.
Management
Information Base
(MIB)
A logical structure, used by the SNMP manager and agent, of the paramet ers
needed for configuring, monitoring, or testing an SNMP device. The MIB is a
hierarchical-naming structure used to uniquely identify SNMP objects
(parameters). It is typically illustrated as an inverted tree.
Master Head-End A head-end that collects television program material from various sources by
satellite, microwave, fiber, and other means and distributes this material to
Distribution Hubs in the same metropolitan or regional area. A Master
Head-end MAY also perform the functions of a Distribution Hub for
customers in its own immediate area.
Media Access
Control (MAC)
Address
A MAC address is used by the link layer protocol to forward packets “one
hop at a time” between the host and the first router and between the first
router and the next router and so on through the network until the packet
arrives at it’s final destination.
Media Access
Control (MAC)
Procedure
In a subnetwork, that part of the protocol that governs access to the
transmission medium independent of the physical characteristics of the
medium, but taking into account the topological aspects of the
subnetworks, in order to enable the exchange of data between nodes. MAC
