References:

• User Datagram Protocol (UDP) -based Data Transfer Protocol (UDT) message - used by Signalling Connection Control Part (SCCP) to send data in connectionless mode using connectionless protocol Class 0 and Class 1. UDT messages are commonly used for Transaction Capabilities Application Part (TCAP) communication within Intelligent Network (IN) services. In Global System for Mobile Communications (GSM) cellular networks, UDT messages are used by the Mobile Application Part (MAP) protocol to send its messages.
• XUDT - Used by SCCP to transmit data with optional parameters, using connectionless classes 0 and 1.
• Signalling Connection Control Part (SCCP) - SCCP is a network layer protocol that provides extended routing, flow control, segmentation, connection-orientation, and error correction facilities in Signaling System 7 (SS7) telecommunications networks.  SCCP is defined in International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) recommendations Q.711-Q.716 [58–63] and for North American markets in American National Standards Institute (ANSI) T1.112 [2].
