The charts created by NetEnforcer are superior to Packeteer's, a consideration if you plan on presenting statistics to a group. Each chart can be displayed as line or area graph, a pie or bar chart, or as a table. Oddly enough, however, you can have only five charts open at once. When we tried opening a sixth graph, we were told we had to close one first. Allot says the next release of the software will allow as many as 10 charts to be open at once, but that limit still seems low and unnecessary. We also found a bug in the GUI that reversed FTP direction in the most active clients/servers list. The clients were listed under most active servers.

Sitara Networks QoSWorks QWX-10000
Sitara's 2U rackmount QosWorks box can be managed through a Web interface or via telnet. It is also the most expensive unit, at nearly $20,000.
Bandwidth-management capabilities are limited compared with that of its competitors; there are only five priority levels, and you can't set a maximum bandwidth per connection. Adding protocols to a policy is also a pain. We were presented with a large hierarchical list of protocols and had to manually search just to get to the TCP protocols. And to add insult to injury, once we found our protocols, we could add only one at a time. To add more, we had to drill through the list again.
