Hi,

How does T-Sat query the traffic from the controller? Where do I go to look for the codes.

And also how does T-Sat use the information that it query and store it into the database?

Thanks.

Hi,

T-Sat collects various information of controller (traffic-information, installed flow-entry, incoming-packets, etc) by hooking event-handlers of Trema.
Specifically, please refer to the file of 'graph/graph.rb'. The processing of hooking Trema event handler is written in here.

And also how does T-Sat use the information that it query and store it into the database?

One of a main processing that T-Sat do is identification of routes.
T-Sat identifies communication routes between any two hosts by flow-entries which user installs.
The implementation of identification-processing is done, but adaptation to the web-viewer-system is under development.
And this feature will be reflected in the topology-graph.
