ARPANET Goes Global: The First International Footprints of the Internet

In the annals of the internet’s history, ARPANET stands out as a foundational pillar. Established by the United States Defense Advanced Research Projects Agency (DARPA), ARPANET was the earliest manifestation of the modern internet. While its initial conception and deployment were confined to the United States, the potential of such a groundbreaking communication network was not lost on international observers. This article delves into the story of ARPANET’s first international connections, marking a pivotal moment when a national project began its transformation into a global phenomenon.

The 1970s were a decade of exploration and innovation in the realm of computer networking. ARPANET, having already demonstrated the viability and utility of packet-switched networking in the US, had naturally piqued international interest. The first steps towards internationalizing ARPANET were taken in 1973 when connections were established with the University College of London (UCL) in the UK and the Royal Radar Establishment in Norway. These were not just technical achievements, but symbolic milestones that represented the merging of pioneering computer science endeavors from different parts of the world.

The UCL connection was particularly noteworthy. Spearheaded by Peter Kirstein, a luminary in computer science, the UCL team established a node called the International Packet Switched Service (IPSS). The IPSS acted as a gateway, facilitating communication between ARPANET and the burgeoning European computer networks. Kirstein’s team not only ensured the technical success of this connection but also became champions of the TCP/IP protocol suite in Europe, the very protocol that would later become the standard for internet communication.

The Norwegian connection, on the other hand, highlighted another crucial aspect of international networking: satellite communication. The link to the Royal Radar Establishment in Norway was, in fact, established via a satellite station in Tanum, Sweden. This utilization of satellite technology demonstrated the potential of intercontinental communication, showing that computer networks could transcend not just political boundaries, but vast geographical ones as well.

As the 1970s progressed, the success of these initial international connections catalyzed interest from other countries. Networks in Germany, Italy, and other European nations began to explore the possibility of connecting with ARPANET. The significance of these developments was twofold. Firstly, they facilitated the exchange of research and technical know-how between computer scientists globally. Secondly, they laid the groundwork for the international infrastructure of the modern internet.

Reflecting upon these early international connections of ARPANET, one discerns a broader narrative: the universality of the human quest for connection and knowledge. ARPANET’s links to networks in other countries were not merely technical achievements; they were emblematic of a world beginning to understand the transformative power of a connected globe. As national networks became intertwined, the vision of a global network of information and communication started taking shape. Thus, while ARPANET was an American initiative, its first international forays signaled the birth of a global digital age, forever changing the way we connect, communicate, and comprehend our world.
