I would have said 10 if they didn't kill the product. I know Blue Folder took a piece of this, but we never got into it and just changed to Auvik and PRTG.
Riverbed Modeler is well suited for wireless, wired, ZigBee, and Cisco networks. All these scenarios are efficiently designed and simulated using Riverbed Modeler, as all the devices are available in its object pallet, so we just need to drag and drop for the best scenario design in the given dimensions. The simulation results are around 95% accurate. However, it is not suited for data security, as data encryption algorithms are not available in Riverbed Modeler.
Riverbed Modeler needs to improve the scenarios of LAN MAN WAN, as the available scenarios under all of these follow a simple area structure that's not connected to the ISP when it comes to simulation. This generates dummy traffic.
Riverbed Modeler also needs to work on the selection of result sets so that, as with most designed networks, we can select any result parameter to show. All the parameters are displayed, whether they are relevant or not. It needs to display only relevant result parameters to select.
The back-end TCP/IP model needs more clarity to expose the structure to some changes.
Again, the main piece was config backups. That is a real big deal, when you are dealing with a lot of customers that don't have a change management process. So changes can be done to a networking device and we need to be able to review what it was one day and what it changed to the next. This happens a lot with internal IT departments, that break something and you support them as an MSP.
The only thing comparable to OPNET is Packet Tracer, which is basic and very limited. Packet Tracer in terms of tool comparison between the two is like OPNET's stone-age relative.
It comes with a costly paid license, but simulating the network before actual deployment saves a lot of costs, in case after deployment we feel performance is not good and we need to change. This would waste a lot of money, but Riverbed saves this money.
Its OPNET GURU academic edition is available free of cost, but with limited functionality, which is good for students in maximum case. This will degrade our sale of Riverbed Modeler.
A one-time investment in Modeler saves a lot of cost regarding networks, topology, designing, and provides a lifetime license with updates.
