 /**
- * \brief The Ccnx representation of a network interface
+ * \ingroup ccnx-face
+ * \brief Implementation of application CCNx face
  *
- * This class roughly corresponds to the struct in_device
- * of Linux; the main purpose is to provide address-family
- * specific information (addresses) about an interface.
+ * This class defines basic functionality of CCNx face. Face is core
+ * component responsible for actual delivery of data packet to and
+ * from CCNx stack
  *
- * By default, Ccnx interface are created in the "down" state
- * no IP addresses.  Before becoming useable, the user must 
- * add an address of some type and invoke Setup on them.
+ * \see CcnxLocalFace, CcnxNetDeviceFace, CcnxIpv4Face, CcnxUdpFace
