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.

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.
