Current Metrics
Current Metrics are agnostic to flow information (based on RTT between nodes).
Under current loads the example network is nicely overprovisioned.
We're going to focus on how much more load we can put on this network before any link exceeds 80% utilization (to allow for microbursts, etc.) This is 1990 Mbps for an OC48. We are going to do this by increasing the values of the Base Demands.
