Скачать или смотреть Live topology updates and measurement with AutoNetkit

AutoNetkit can be run in "monitor" mode, where it will rebuild the network models if the input changes. We can combine this with a "diff" script, which watches for changes to the models, and acts on these changes. In this example the diff script will automatically apply the ospf weight changes to the altered nodes.
By combining these pieces, we can modify the input topology in yEd, with the changes automatically compiled and applied to the running network, and the automated measurement detecting, analysing, and visualising the results.

The automated measurement system collects measurement data such as "show ip route", also using Exscript. This is parsed using TextFSM, and the results compared to the topology model. NetworkX shortest path algorithms are used to verify the routes match. The results are sent to the visualisation engine. Routes that match the calculated paths are shown in green.

Note: this is standard Netkit and Quagga installation --- there are no special scripts running on the Quagga VMs.

All components of AutoNetkit are modular and can be extended. www.autonetkit.org
