In 1977, I was manager of a small group “Distributed System Studies” in the Thomas J. Watson Research Center. At that time, ARPANET had already grown into a big US-wide meshed network using innovative technology such as adaptive routing and datagrams. By this comparison, IBM’s System Network Architecture (SNA) was quite backward. It grew out of so called “Telecommunication Access Methods” and was basically a feeding network for a single mainframe complex with tree topology (Fig. 1).
