Lawrence Technological University is among Michigan’s largest independent colleges and also Michigan’s first completely wireless laptop campuses, as well as one of the largest wireless networks in the Midwest.

This recently published case study demonstrates how successful network traffic analysis can be performed using NetFlow reporting with Scrutinizer NetFlow Analyzer. Monitoring NetFlow exported from devices such as Cisco ASA’s, routers, switches, and numerous other NetFlow compatible devices simplifies the task of managing your network, whether wired or, in LTU’s case, fully wireless.

Using Scrutinizer as their traffic management tool has helped protect the school from legal exposure due to illegal downloads of music, movies and applications. NetFlow analysis also helped LTU identify suspicious activity and block possible malicious users.

“With 60 servers in our virtualized environment and thousands of users constantly accessing our network from all across campus, managing the high volume of network traffic was a real challenge,” commented Chavis. “We had issues with lots of network noise and fluctuating response times. Enforcing security was also a major concern. Troubleshooting problems was difficult and time-consuming. For example, we had a denial of service occur in one of the buildings on campus. It took us hours to identify that the source was a bad printer card.” – Tim Chavis, Executive Director, IT Services for the school’s Edward Donley Computer Center
