Since the inception of the Internet in the 1960's, much effort has been made in standardizing how computers connect to it. In 1982, the International Organization for Standards (ISO) realized that during that period many ad hoc networking systems were already using the TCP/IP protocol for communications and thus adapted it as a standard in its model for the Internet network [2]. The main driver for IP convergence, at that period, was the growth in data traffic through wide area networks (WANs) established by local companies. Furthermore, in 1991, the Internet was open for commercial use, and that demanded a reduction in the total cost of operating the network to cope with 1 million Internet hosts that materialized in only 1-year time. Telecommunications companies like AT&T understood the potential and worked on standardizing the network offering voice services over IP networks that managed the separation between voice and data transmission [3].
At the same time, Ford had launched its plan to update its infrastructure, and seized the opportunity brought by the global movement of integrating the voice, fax transmission network with data transmission and expanded its WAN to include its offices in Europe and elsewhere. The financial benefits also came from the fact that Ford adapted the TCP/IP protocol from the beginning and made sure that all its technical infrastructure upgrades adhere to the standards. This made the transition of its system to the Internet as cost effective as it could be.
