Now, outsourcing is not for everyone, but that doesn't mean that license management should be neglected. License management is one aspect of asset management that many managers tend to overlook. That's a shame, because properly applied license management can keep you out of trouble with software vendors and can also save you money. Licensing software can not only tell you what you own, it can tell you what your users use -- and don't use.

If you've ever used a network monitor such as Windows' or Solaris', then you are familiar with sniffers. Commercial sniffers gather statistics and can work with various threshold and defined events. One collection of tools that has been around a few years is dsniff 2.3 (http://www.monkey.org/~dugsong/dsniff/). This is actually a set of tools that not only audit, but test for network penetration.

This usually involves the arduous task of combing through extremely long system log files. That's where log-monitoring tools like swatch can help.

Many of us scoff at the impending shortage of IP addresses and the need to move to IPv6, but you may want to consider the expanded capabilities the new protocol can bring to your network.

Fundamental concepts such as medium access mechanisms, frame formats, security, and the physical interfaces build the foundation for understanding more advanced and practical concepts. In keeping with this theme, this chapter covers mobility. Mobility is the quality of being capable of movement or moving readily from place to place. 802.11 WLAN devices provide this kind of untethered freedom. But there's more to mobility than the lack of a network cable. Understanding how mobility is implemented in 802.11 arms you with the knowledge you need to support or facilitate mobile applications. This chapter specifically covers the characteristics of roaming, Layer 2 roaming, Layer 3 roaming and an introduction to Mobile IP.

This scenario has forced one group to put off its WLAN implementation indefinitely. http://searchnetworking.techtarget.com/originalContent/0,289142,sid7_gci948806,00.html?track=NL-314 ___________________________________________________________________ **************** CONTACT SEARCHNETWORKING.COM ***************** E-mail us at mailto:[EMAIL PROTECTED] Click here for specific contact information and to meet our editorial team: http://searchnetworking.techtarget.com/meetEditorial/0,289131,sid7,00.html?track=NL-314 To sponsor this or any other TechTarget newsletter e-mail Gabrielle DeRussy, Director of Site Sales at mailto:[EMAIL PROTECTED] ::::::::::::::::::::: ABOUT THIS NEWSLETTER :::::::::::::::::::::: This e-newsletter is published by TechTarget, the most targeted IT media and events company.
