+ *
+ * +----------+ 1Mbps +--------+ 1Mbps +----------+
+ * | consumer | <------------> | router | <------------> | producer |
+ * +----------+ 10ms +--------+ 10ms +----------+
+ *
+ * This scenario demonstrates how to use content store that responds to Freshness parameter set in
+ *Datas.
+ * That is, if producer set Freshness field to 2 seconds, the corresponding content object will not
+ *be cached
+ * more than 2 seconds (can be cached for a shorter time, if entry is evicted earlier)
