Riverbed Modeler provided a comprehensive development environment to model and analyze communication networks and distributed systems. The application has been sunsetted, and is no longer available.
[Micro Focus Network Node Manager i (formerly HP Network Node Manager)] is like you implement it, setup monitoring and alerting and forget it forever until any major activity is there and that is possible because of the product's stability. Another reason for product stability is less features as compared to other vendor tools and its own inbuilt database.
Most customers would like to see NNM get away from using some Java applets.
In environments where we see more than 10 different network device vendors in production, we see issues with L2 mapping. Different vendors use different L2 protocols. This can cause an issue with L2 discovery and mapping.
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.
NNMi's user interface is described as well-designed and intuitive, making it easy for users to navigate and perform tasks quickly, thereby enhancing the overall user experience. The system offers a powerful network discovery mechanism that maps out your network's physical and virtual topology, enabling you to visualize connections between devices and identify potential issues. Fault monitoring is at its best. NNMi provides a unified environment for viewing faults, availability, and performance data, consolidating essential information into a single platform.
Support is long and arduous and often are unable to help resolve the issue. We often have to do escalations or duty manager to get things moved. Even with a technical account manager, we do not see much improvement from a support point of view. This is an area where Micro Focus has a lot of improvement to do.
NNMi is best suited for enterprise-grade, large to very large infrastructure. You have fewer servers to install the product and manage all your devices through a single server, which also enhances ease of use.
There exist many simulation simulators like NS2, but Riverbed Modeler is one of the simulators which introduces the GUI interface for networking. The platform just changes the scenario of networking, as it makes it so easy to understand and implement. The functionality almost listed every possible network in the world, which is not given by any other tool. Moreover, it is releasing updated versions to match with the latest technology.
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.
