Traffic Aware Workflow

Unlike traffic-oblivious topologies, traffic-aware architectures dynamically adapt the network topology based on runtime traffic patterns. This requires a feedback loop to collect traffic information and update the network topology accordingly. All of this functionality is encapsulated in openoptics.Toolbox.BaseNetwork.start_traffic_aware(), where users only need to specify the topology generation function and the routing algorithm they wish to use. The configuration workflow is nearly identical to the previous examples of traffic-oblivious architectures.

Try ping between nodes, what do you observe on the dashboard?
