"""This profile allocates two bare metal nodes and connects them together with a link. We specify that the link be *shaped*, setting the bandwidth, latency, and packet loss for the link. 

Instructions:
Click on any node in the topology and choose the `shell` menu item. When your shell window appears, use `ping` to test the link."""
