+ *
+ * This strategy adds a CongestionMark to each Interest it forwards. Otherwise, behaves like
+ * BestRouteStrategy2.
+ *
+ * The value of the added CongestionMark can be specified through a strategy parameter (defaults
+ * to 1). In addition, an optional boolean parameter specifies whether the strategy will preserve
+ * existing CongestionMarks (default) or replace them.
