/**
- * @file
+ * @file face.h
+ *
+ * This file implements a general face type. The purpose of a face is to
+ * carry the needed information to forward interest and data packets to the
+ * next node in the network. There are two type of faces: complete faces (in short
+ * faces), and incomplete faces (in short ifaces).
*
- * @brief Face
+ * A face that does not contain the indication of the adjacency is an
+ * incomplete face (iface), otherwise it is considered to be complete. Ifaces are
+ * used to forward data back to the previous hICN hop from which we received an
+ * interest, while faces are used to forward interest packets to the next hicn node.
+ * Faces and ifaces are created at two different points in time. Faces are created
+ * when a route is added, while ifaces are created when an interest is received.
+ * In details, faces and ifaces carry the following information:
+ * - nat_addr: the ip address to perform src nat or dst nat on interest and data packets, respectively;
+ * - pl_id: the path label
+ * - locks: the number of entities using this face. When 0 the face can be deallocated
+ * - dpo: the dpo that identifies the next node in the vlib graph for processing the vlib
+ * buffer. The dpo contains the dpo.dpoi_next field that points to the next node
+ * in the vlib graph and the dpo.dpoi_index which is an index to adj used by the next node
+ * to perform the l2 rewrite. In case of ifaces, it is likely we don't know the
+ * adjacency when creting the face. In this case, the next node in the vlib graph
+ * will be the node that performs a lookup in the fib. Only in case of udp tunnels,
+ * which are bidirectional tunnel we know that the incoming tunnel is also the outgoing
+ * one, therefore in this case we store the tunnel in the dpo.dpoi_index fields. For
+ * all the other tunnels (which are most likely unidirectional), the source address of
+ * the interest will be used to retrieve the outgoing tunnel when sending the corresponding
+ * data back.
+ * - sw_if: the incoming interface of the interest
+ * - fib_node, fib_entry_index and fib_sibling are information used to be notified of
+ * changes in the adjacency pointed by the dpo.
*
- * This file implements a general face type. A face is carried through nodes as a
- * dpo. The face state (hicn_face_t) is the object pointed by the
- * dpoi_index in the dpo_id_t (see
- * https://docs.fd.io/vpp/18.07/d0/d37/dpo_8h_source.html).
- * A face state that does not contain the indication of the l2 adjacency is an
- * incomplete face (iface), otherwise it is considered to be complete. Each face type
- * provide specific node for processing packets in input or output of complete
- * and incomplete faces.
+ * We maintain two hash tables to retrieve faces and ifaces. In particular one hash table which
+ * index faces and ifaces for nat_address, sw_if and dpo. This is used to retrieve existing faces
+ * or ifaces when an interest is received and when an new face is created. A second hash table that
+ * indexes vectors of faces for nat_address and sw_if. This is used to retrieve a list of possible
+ * incoming faces when a data is received.
