Deﬁnition

L2TP

Layer 2 Tunnel Protocol

. Helps build virtual private networks in the dial access space, and

provides

Layer 2 Forwarding

L2F) protocol and

Point-to-Point Tunneling Protocol

(PPTP).

LAG

Link Aggregated Group

. Aggregates ports or VLANs into a single virtual port or VLAN.

LAN

Local Area Network

. A network contained within a single room, building, campus or other

limited geographical area.

Layer 2

Data Link Layer or MAC Layer

. Contains the physical address of a client or server station.

Layer 2 processing is faster than Layer 3 processing because there is less information to

process.

Layer 3

Network Layer

. Contains the logical address and protocol type (IP, IPX, etc.). Layer

3 traffic can also be prioritized and forwarded based on packet information, such as

the source and destination address. Layer 3 processing takes longer than Layer 2

processing, as there is more information to process.

Layer 4

Establishes connections and ensures that all data arrives at the correct destination.

Packets inspected at the Layer 4 level are analyzed and forwarding decisions are based

on their applications.

LCP

Link Control Protocol

. Manages authentication, compression, and encryption.

Load Balancing

Enables the even distribution of data and/or processing packets across available network

resources. For example, load balancing may distribute the incoming packets evenly to all

servers, or redirect the packets to the next available server.

MAC Address

Media Access Control Address

. The MAC Address is a hardware speciﬁc address that

identiﬁes each network node.

MAC Address Learning

Characterizes a learning bridge, in which the packet’s source MAC address is recorded.

Packets destined for that address are forwarded only to the bridge interface on which that

address is located. Packets addressed to unknown addresses are forwarded to every

bridge interface. MAC Address Learning minimizes trafﬁc on the attached LANs.

MAC Layer

A sub-layer of the Data Link Control (DTL) layer.

MAN

Metropolitan Area Network

. A communications network covering a metropolitan area or a

suburb.

Mask

A ﬁlter that includes or excludes certain values, for example parts of an IP address.

MD5

Message Digest 5

. An algorithm that produces a 128-bit hash. MD5 is a variation of

MD4, and increases MD4 security. MD5 veriﬁes the integrity of the communication and

authenticates the origin of the communication.

MDI

Media Dependent Interface.

A cable used for end stations.

MDIX

Media Dependent Interface with Crossover (MDIX)

. A cable used for hubs and switches.

MDU

Multiply-Divide Unit.

A high-speed circuit that performs multiplication and division within

the CPU.

MIB

Management Information Base

. MIBs contain information describing speciﬁc aspects of

network components.

MTU

Maximum Transfer Unit

. Speciﬁes the maximum frame size that can be transmitted over

a network. Frames that exceed the MTU must be broken into smaller frames.

Multicast

Transmits copies of a single packet to multiple ports.

Network Processor

CPU chips that are optimized for networking and communications functions.
