MME Design
**********

The srsMME must maintain three EPC interfaces, the S1-MME, the S11 and the S6a interfaces. The S1-MME will use an SCTP (many-to-one) socket and the S11 will use the GTP-Cv2 protocol over UDP. The S6a will be implmented as a Diameter application over UDP.

The main loop of the MME will
