+<h1>FlowScan</h1>
+<p>by Dave Plonka</p>
+
+<p>
+FlowScan is a network analysis and reporting tool that processes flow
+files generated by Cflowd, <a href="http://www.caida.org/Tools/Cflowd/">http://www.caida.org/Tools/Cflowd/</a>,
+which collects flow data from Cisco routers.
+</p>
+
+<p>
+Sample graphs produced using FlowScan can be seen here:
+<a href="http://wwwstats.net.wisc.edu">http://wwwstats.net.wisc.edu</a>.
+</p>
+
+<p>
+FlowScan's features include:
+</p>
+
+<ul>
+
+<li>
+a "CampusIO" report which allows one to generate graphs showing traffic
+by IP protocol, traffic by "well-known" service, and traffic passed
+between Autonomous Systems.
+</li>
+
+<li>
+a "SubNetIO" report which maintains RRD files containing information
+on how many bytes, packets, and flows have been sourced from or destined
+for each subnet.
+</li>
+
+<li>
+the ability to determine bandwidth usage by "elusive" application protocols
+such as "RealMedia" and "Napster" using an adaptive, state-based measurement
+technique.  See <a href="http://net.doit.wisc.edu/data/Napster/">http://net.doit.wisc.edu/data/Napster/</a> for more details.
+</li>
+
+<li>
+a modular report mechanism that enables users to write or customize
+reports that can either derived from existing reports or be altogether
+new ones.
+</li>
+
+</ul>
+

+FlowScan is available at
