Book excerpts

Chapter download: Bandwidth management
This selection from CCSP Self-Study: Cisco Secure Virtual Private Networks (CSVPN) explains how you can configure the Concentrator to deliver the most effective bandwidth settings for your particular network.

Chapter download: Open Source Network Administration, Chapter 3
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.
