NETWORK ANALYZERS:
A network analyzer also known network monitor or a network sniffer is used to calculate the performance of or debug a network.
It may report statistics such as capacity distribution of frame size, utilization, token circulation time or collision rate.

Several desktop computers have interface that may be configured for promiscuous type. When combined with software computer can calculate any frame on LAN.
