+ * This is the node encoutered by interest packets after the hicn-interest-pcslookup.
+ * This node aggregates an interest in the PIT or forward it in case of a retransmission.
+ * If the interest must be retransmitted the next vlib node will be on of the
+ * hicn6-face-output or hicn4-face-output nodes. If the pit entry is expired the next vlib node
+ * will be the hicn-strategy node, otherwise the vlib buffer is dropped.
