+# NullLinkProvider topology description (config file).
+#
+# Dot-style topology graph. Each controller's topology begins with
+#
+# graph <node ID>, followed by a list of links between braces.
+#
+# The links are either bidirectional (--) or directed (->). The directed
+# edges are used to connect together Null devices of different controllers.
+# The endpoint has the format:
+#
+# devID:port:NodeId
+#
+# The NodeId is only added if the destination is another node's device.
