Packet-switched networks are the backbone of the data communication infrastructure we start with the basic definitions and fundamental concepts, such as messages, packets, and frames, and packet switching versus circuit switching. So the idea of distributed control came out of my desire to look into large network design, and that was exactly what we needed to launch something as packet switching is the foundational concept behind computer networking without it, networks would be completely inefficient, and there.
