  ---

  To successfully baseline a network it is important to consider two functions; performance at protocol level and performance at application level. There are many significant metrics to consider at the protocol level, but only a few which are critical. The most important is bandwidth utilization compared with bandwidth availability. The most likely cause of poor network performance is insufficient bandwidth. Trending bandwidth utilization allows you to recognize problem areas, provide enough bandwidth to reach performance objectives, and predict future capacity requirements. Changes in bandwidth utilization patterns also provide a clear indication of network usage alterations, such as a change in end-user behavior, or the unauthorized addition of an application.

  ---

  A packet analyzer is a computer program or a piece of computer hardware that can intercept and log traffic passing over a digital network or part of a network.As data streams flow across the network, the sniffer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content.
