Table C-1. Glossary

 

Loop

An event that occurs when two network devices are connected by more

 

than one path, thereby causing packets to repeatedly cycle around the

 

network and not reach their destination.

MAC

Media Access Control. A protocol specified by the IEEE for determining

 

which devices have access to a network at any one time.

MAC address

Media Access Control address; also called hardware or physical address.

 

Most devices that connect to a LAN have a MAC address assigned to them,

 

as they are used to identify other devices in a network.

Port monitoring

The ability to monitor the traffic passing through a port on a device to

 

analyze network characteristics and perform troubleshooting.

Port speed

The speed that a port on a device uses to communicate with another device

 

or the network.

Port trunking

The ability to combine multiple ports on a device to create a single, high-

 

bandwidth connection.

Protocol

A set of rules for communication between devices on a network.

Quality of Service

A term to describe delay, throughput, bandwidth, and other factors that

 

measure the service quality provided to a user.

Segment

A section of a LAN that is connected to the rest of the network using a

 

switch, bridge, or repeater.

SNMP

Simple Network Management Protocol. An IETF standard protocol for

 

managing devices on a TCP/IP network.

Switch

A device that interconnects several LANs to form a single logical LAN that

 

comprises of several LAN segments. Switches are similar to bridges, in that

 

they connect LANs of a different type; however they connect more LANs

 

than a bridge and are generally more sophisticated.

TCP/IP

Transmission Control Protocol/Internet Protocol. This is the name for two of

 

the most well-known protocols developed for the interconnection of

 

networks. Originally a UNIX standard, TCP/IP is now supported on almost

 

all platforms, and is the protocol of the Internet.

 

TCP relates to the content of the data traveling through a network —

 

ensuring that the information sent arrives in one piece when it reaches its

 

destination.

 

IP relates to the address of the endstation to which data is being sent, as

 

well as the address of the destination network.

Traffic prioritization

Giving time-critical data traffic a higher quality of service over other, non-

 

critical data traffic.

VLAN

Virtual LAN. A logical association that allows users to communicate as if

 

they were physically connected to a single LAN, independent of the actual

 

physical configuration of the network.
