We have a Disaster Recovery (DR) site. We would like to improve our traffic shaping and optimize the bandwidth for a smooth operation between the user-side and the DR one.
Which device (or a technique) can help?
Thank you for the help.

Hello @Kaushlendra Singh,
I would suggest SD-WAN as the best suitable technology for shaping your traffic between these 2 sites.
And if you don't want to invest, you can utilize your current firewall to create IPSec VPN for the backup line, and the primary can be P2P with increased bandwidth. For that, P2P needs to be terminated on your firewall.
We are planning on installing the new IBM Tivoli "NOI" Application from scratch on new servers in a "high availability" configuration. Has anyone done this on their own (without an IBM consultant on site to assist)? We are currently running IBM Tivoli Netcool (see below). Thanks

For Network Analyzer, you can use Elastiflow. It's pretty complete even though its development has stopped lately (we have recently deployed it in production for a customer). It is still just as good as it was a few years ago.
For Network Configuration Management, it really depends on the sets of features you're looking for. But, you can use the Ansible & Gitlab combo. We've written a full tutorial for it on our website: https://www.zen-networks.io/ne...
For the network configuration manager, I would take a look at Auvik. It is free to try and easy to deploy.
They do a decent job of network traffic analyzing. If you want to look inside the traffic only there is Wireshark.
Hi, in this case, Nagios Network Analyzer could be a good option, the big advantage is that is very easy to connect with Nagios XI and you can see information on networks and you can verify different information using SNMP on Nagios XI too, you can enjoy of all information in one place, other features are related with very behavior on a specific IP or port, this is normal in all solutions, I believe the disadvantage in this solution is that it is not open source (Nagios has Nagios Core, that is open source, is amazing but you need a little bit knowledge about Linux, nothing complex). I used other solutions in other labor life (lol) like cacti, but with this solution, you should in a short time need to use other solutions for servers and other solutions to log. I hope that my information can help you.
For Network Configuration Manager, have a look at Device Config functionality that is part of NetCrunch. it includes predefined profiles of over 180 network device types, plus an editor that helps you easily create new profile definition for any less popular device that you have in your network.

I recommend checking Riverbed, depending on what you need: SNMP, MIB, or Flow. They have many tools available but they are not open source.
