ISL
Interswitch Link. An Avaya proprietary mechanism to tag packets with VLAN and
priority information across the backbone. This allows two Avaya devices to act as a
single logical entity.
ISO
International Standards Organization. A voluntary organization founded in 1946,
responsible for creating international standards in many areas, including computers
and communications.
Jabber
An error condition in which a network device continually transmits random,
meaningless data onto the network. In IEEE 802.3, Jabber refers to a data packet, the
length of which exceeds the maximum length prescribed in the standard.
LAG
Link Aggregation Groups (LAGs) provide a method of creating a high-bandwidth
link. A LAG consists of a group of ports acting as a single logical port. All ports
participating must have the same configuration.
LAN
Local Area Network. A high-speed, low-error data network that spans a limited
area. LANs connect workstations, peripherals, terminals, and other devices in a
single building or other geographically limited area.
LANE
LAN Emulation. A technique that specifies the interfaces and protocols needed for
providing LAN-supported functionality and connectivity in an ATM environment.
This enables legacy protocols to be interoperable with ATM protocols, interfaces,
and devices.
LAN Emulation
A technique that specifies the interfaces and protocols needed for providing LAN-
supported functionality and connectivity in an ATM environment. This enables
legacy protocols to be interoperable with ATM protocols, interfaces, and devices.
LEC
LAN Emulation Client. A LEC is an entity in an end system that performs data
forwarding, address resolution, and other control functions for a single end system
within a single ELAN. A LEC also provides a standard LAN service interface to any
higher-layer entity that interfaces with the LEC. Each LEC is identified by a unique
ATM address, and is associated with one or more MAC addresses reachable
through that ATM address.
