+# router section defines topology nodes and their relative positions (e.g., to use in visualizer)

+# Note that `node` can be any string. It is possible to access to the node by name using Names::Find, see examples.

+# link section defines point-to-point links between nodes and characteristics of these links
+link

+# srcNode   dstNode     bandwidth   metric  delay   queue
+# bandwidth: link bandwidth
+# metric: routing metric
