The person behind the work
Robert Kahn developed the idea of connecting independently designed packet networks through an open internetwork architecture. Working with Vinton Cerf, he helped design the protocols that became TCP/IP. At ARPA he also guided research and deployment that turned networking ideas into functioning infrastructure. He later founded CNRI to support emerging information technologies. His contribution joined architectural invention with the organizational work needed to make networking succeed.
The contribution, explained
Vinton Cerf and Robert Kahn developed the foundations of internetworking. IP carries packets across interconnected networks; TCP can provide reliable ordered delivery over that packet service. This layering allowed diverse underlying networks to participate without first becoming identical.
Why it matters
An open set of common protocols helped the Internet grow across machines, institutions and network technologies.
