problem is detected by the passive

When a problem is detected by the passive monitoring tools, traffic can be generated using the active tools, allowing one to collect

additional data to further study the problem. By having these monitors deployed at every router along the path, we can study only

the section of network that seems to be having the problem. [Tierney04].

SCNM [Agarwal03] is intended to be installed and used mainly by network administrators; however average users can use a subset

of its functionality. Although average users are capable of using part of the SCNM monitoring environment they are only allowed

to monitor their own data.

In conclusion, SCNM is another combinational monitoring tool that utilizes both active and passive monitoring to help

administrators monitor and analyze their networks
