Question: What transport protocol is mandated for carrying Diameter messages over the V6 interface in Inter-V2X Control Function Signalling aspects?
Option 1: TCP (Transmission Control Protocol)
Option 2: UDP (User Datagram Protocol)
Option 3: SCTP (Stream Control Transmission Protocol) as per IETF RFC 4960
Option 4: HTTP (Hypertext Transfer Protocol)
Explanation: In the context of Inter-V2X Control Function Signalling, reliability and efficient handling of multiple simultaneous connections are crucial. SCTP is particularly suited for such requirements due to its ability to handle multiple streams within a single connection, providing reliable, sequenced delivery of messages with built-in congestion avoidance, making it ideal for transporting Diameter messages over the V6 interface.
