Apr 13, 2016 · Definition Of UDP UDP or User Datagram Protocol is a connectionless protocol found in the transport layer of TCP/IP Model. It neither establishes a connection nor checks whether the destination computer is ready to receive or not; it just sends the data directly. UDP is used to transfer the data at a faster rate.

Oct 29, 2019 · The UDP source port is 53 which is the standard port number for unencrypted DNS. The UDP payload is therefore likely to be a DNS answer. That suggests that the source IP address 192.168.2.254 is a DNS resolver while the destination IP 192.168.2.14 is the DNS client.
The (D)TLS handshake is a lock-step procedure: messages need to arrive in a certain order and cannot be skipped. To achieve this on top of UDP, DTLS has its own retransmission mechanism, which needs timers. In Mbed TLS, the SSL module accepts a pair of callbacks for timer functions, which can be set using mbedtls_ssl_set_timer_cb().
