Transmission Control Protocol (TCP)
TCP prevents loss of data, duplication, and damage. It ensures that the sent message
isn't out of order. These characteristics make it a reliable protocol, unlike UDP.
Please refer to the RFC 793 guide for more information about TCP.
TCP synchronizes using a three-way handshake. Synchronization between two nodes
begins when a TCP segment is sent with the SYN (0x02) lag set.
TCP sockets are one-to-one. A source node transmits messages to the destination node.

duplicated transmission.

to the destination.
