Thus ignorance to these aspects, leaves a network dangerously exposed.

b. There are myriad of reasons for collecting data.

Accounting management is interested in using the data as the basis for billing and attributing usage data to the actual user while Performance management is interested in using the data for statistical purposes, such as getting a utilization of the network and detecting statistical trends.
