scam: Sticky fingers at fault
Throwing bandwidth at a network performance problem rarely solves anything. But why did we think it
would? This column guides you to think "outside the box."
Optimizing and managing bandwidth
Monitoring
bandwidth on the WAN
Bandwidth is one of the areas network engineers can monitor in order to solve problems of WAN
performance. In this tip, Brien Posey looks at two tools for bandwidth measurement -- one powerful
high-end monitoring tool, and one low-end tool that is flexible and free.

This featured chapter describes MRTG. MRTG produces Web pages that display graphs of bandwidth use
on network links on daily, weekly, monthly, and yearly scales. This can be an invaluable tool for
diagnosing network problems because it not only indicates the current status of the network but
also lets you visually compare this with the history of network utilization. (PDF)
