[c-nsp] Forecasting

[Cheung, Rick]

	Hi, folks. I've used a variety of network management tools, both
commercial and open sourced. So far, I've only come across one that graphs
trend lines for utilization for forecasting, and this is with Lucent's
Vitalsuite.

	Is anyone else aware of any other tools, preferably open sourced,
that can graph trend lines to anticipate usage 3-6 months out? 

	Apparently, RRDTool/Cricket fully supports the Holt-Winters
algorithm, which can be configured to display the confidence bands to report
on aberrant data, but the time scale is still based on actual usage.



Thanks,
Rick Cheung
