Heavy Networking 524: Network Modeling With Open Source pyNTM
Today on Heavy Networking, network modeling. Oh, you mean like GNS3? No, not like GNS3. Rather, we’re covering the Python Network Traffic Modeler, or pyNTM, an open-source network modeling tool. Creator Tim Fiola explains what network modeling is and how you can use this tool to help you make design decisions and avoid costly mistakes.
The pyNTM software lets you create a WAN topology and apply a mix of traffic to it. The modeling engine converges the model to simulate network state based on traffic traversing the topology. That network state reflects details such as traffic paths, interface utilization, RSVP reserved bandwidth, and more.
Tim is a network automation and modeling enthusiast.
We discuss:
* Differences between virtual labs and network simulation/modeling
* What pyNTM does and the problems it can solve
* What a traffic matrix is
* Modeling vs. best practices and rules of thumb
* How pyNTM uses Python under the hood
* More
