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). - * - * 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. - * - * 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. - */ - -/** - * @brief Structure representing a face.
