The ARPANET Logical Map is the result of the hard work of minds such as Bolt Beranek and Newman Burlington. The map was designed and developed at ARPANET, and it was introduced in the year 1977. The map basically shows the topologies of ARPANET in the year 1977, during the month of March.
The map has undergone much scanning, starting from Bolt Beranek and Newman Burlington, and also by Larry Press, who is from the ARPANET Completion Report. The ARPANET is the first packet switching network in the entire world, which was completely operational. The network is the first of its kind which made use of the TCP/IP, and can be said to have contributed the most to the advent of the modern day internet.
The network was originally designed to help in the studies conducted in different research laboratories and universities in the USA. But obviously, as is evident, the ARPANET logical map now is most responsible for the internet as we know it today. And the network, along with the TCP/IP, creates the main working basis of the present day global internet, and one of the most prominent aspects of this network is the packet switching protocols.
