Warning network engineers

Due to the Coronavirus disease (COVID-19) all TCP applications have to be converted to UDP to avoid Handshakes.

The TCP handshake

TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these four flags is performed in three steps: SYN, SYN-ACK, ACK.
