 *
 * This Helper will create an EPC network topology comprising of a
 * single node that implements both the SGW and PGW functionality, and
 * an MME node. The S1-U, X2-U and X2-C interfaces are realized using
 * EmuFdNetDevice; in particular, one device is used to send all the
 * traffic related to these interfaces.
