Techopedia explains Bandwidth Analyzer
A bandwidth analyzer is part of network management software. It is usually installed or operates at the network gateway, and records each packet that moves in or out of the network. Typically, a bandwidth analyzer's key function is to provide the amount/size of data that is downloaded or uploaded and the overall bandwidth being used.
Some enterprise/advanced-level bandwidth analyzers can drill into the details of each network packet and provide performance and security-related data. This can include peak usage time, most-used protocols, active systems, the source and destination IP addresses of each packet and more. Moreover, it can also alert a network administrator when a bandwidth use threshold is reached, and inform the administrator about application/user/system-specific bandwidth use details.
