===TCP/IP===
While working at DARPA's [[IPTO|Information Processing Techniques Office]] Kahn took up work on a current project to establish a satellite packet network, and began a project on creating a ground-based radio packet network. Through his work in these projects he became aware of the need for an open-architecture network; wherein any network could communicate with any other individual hardware and software configuration. He created four goals for what was to the [[TCP| Transmission Control Protocol]]:
# Network Connectivity - any network could connect through another via a gateway
# Distribution - No central hub or control
# Error Recovery - Lost packets would need to be retransmitted
# Black Box Design - No internal changes would be necessary to facilitate new networks

Less than a year later, in 1973, Vinton Cerf joined the project. They began by researching reliable data communications across packet radio networks, accounted for lessons learned from the [[Networking Control Protocol]], and subsequently created the next generation [[TCP|Transmission Control Protocol]], which was to become the standard protocol continually used on the Internet.

They designed powerful error and retransmission capabilities into TCP in order to provide more reliable communications; the design was thus formed around two protocols, TCP/IP. TCP is in charge of handling high level services, like the retransmission of lost packets, and [[IP]] addresses and transmits packets.<ref>[http://www.livinginternet.com/i/ii_kahn.htm LivingInternet.com]</ref>
