The solution conceived by ARPA, the government agency in charge of the development of the project, was to create an infinite series of alternative routes capable of circulating information in any condition, achieving the aim of protecting the transmission of the data flow sent .
The roads of this first communication network, which was called Arpanet, had to connect nodes capable of processing, transmitting and receiving data in any situation, even in the event of a nuclear attack.
In practice, each node had to be able to choose, if necessary, an alternative way to reach another destination node, addressing the data with the help of other available channels.
The management of the data flow, to be transmitted through this telecommunication network, was entrusted to electronic elaborators to replace the normal telephone exchanges.
