Simulate the typical latency on a WAN circuit in the lab dur-•
ing a scan. is will help gauge scan performance as well as
impact to production systems. Some vendors provide tools
that can use a packet capture from a network segment and a
performance profile, and then re-create the user experience
with the scan traffic and any given application injected. For
example, an accounting system could be placed on one side
of such a device while the scanner is on the other side. e
device simulates the traffic conditions at a peak time for a
particular office using a previously gathered profile.
