network analyzer

[′net‚wərk ′an·ə‚līz·ər]
(computer science)
An analog computer in which networks are used to simulate power line systems or physical systems and obtain solutions to various problems before the systems are actually built.

network analyzer

A hardware device or server software that captures packets transmitted in a network for routine inspection and problem detection. Also called a "sniffer," "packet sniffer," "packet analyzer," "packet sampler," "traffic analyzer" and "protocol analyzer," the hardware analyzer plugs into a port on a network switch and decodes one or more protocols into a human-readable format for the network administrator. It can also store packets for further analysis later on.

In order to alert admins about traffic problems, packets are analyzed in real time. Hardware network analyzers can detect voltage and cable problems, whereas software analyzers cannot. See IPFIX, sFlow and port mirroring.
