A Tale of Two Internets

In 1974, the fathers of the Internet published research on what has become the Internet Protocol, forming what we know today as the Internet. It took another nine years to transform this research into the TCP/IP that most of you know. The switch to TCP/IP was completed in January 1983. In one single day the old protocol, NCP, was abandoned and TCP/IP was proclaimed to be the only protocol family of use. Everyone on the network at that time had to implement TCP/IP within 14 months. This was a forced transition, and quite a painful ordeal, but the push was needed because without it the transition would have never happened. At that time, although it seemed difficult, the transition was still feasible as there were only a few hundred nodes connected to the network back then.
