'''Robert E. Kahn''' is the co-inventor of the [[TCP/IP]] system that established the architectural basis of the Internet. He worked with [[Vinton Cerf]] to write the famous paper, "A Protocol for Packet Network Interconnection".<ref>[http://www.nytimes.com/2005/02/16/technology/16internet.html NYTimes.com]</ref>

==The Beginning==
==The Beginning==
Dr. Kahn first met Dr. Cerf at U.C.L.A. in 1969, after the ARPANET nodes had been nationally distributed. At that time, he was working at an engineering firm in Cambridge, Mass., and travelled to U.C.L.A. to experiment with the new network.
Dr. Kahn first met Dr. Cerf at UCLA in 1969, after the [[ARPANET]] nodes had been nationally distributed. At that time, he was working at an engineering firm in Cambridge, Mass., and travelled to UCLA to experiment with the new network. While at Bolt Beranek and Newman in Cambridge, Mr. Kahn helped build the [[Interface Message Processor]].<ref>[http://www.livinginternet.com/i/ii_kahn.htm LivingInternet.com]</ref>
By the time they published their famous paper, in 1973, Vinton was a professor at Stanford and Robert was working within the Defense Department's [[Advanced Research Projects Agency]], the founders of the [[ARPAnet]]. They did not claim their protocols as [[Intellectual Property|intellectual property]], and thus it was able to flourish as an open standard.<ref>[http://www.nytimes.com/2005/02/16/technology/16internet.html?pagewanted=2 NYTimes.com]</ref>

In 1972, while working at [[DARPA]], he gave a presentation of the an ARPANET network, connecting 40 different computers at the International Computer Communication Conference. This was the first time that much of the computing world, and the general population were introduced to the revolutionary network.<ref>[http://www.livinginternet.com/i/ii_kahn.htm LivingInternet.com]</ref>
Robert Kahn has rejected any type of "Father of the Internet" label, saying that today's Internet was created through a community effort.<ref>[http://www.theregister.co.uk/2007/01/18/kahn_net_neutrality_warning/ TheRegister.co.uk]</ref>
===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>
==Contemporary Work==
In 2007, Robert strongly came out against [[Net Neutrality]] legislation; this type of legislation is largely opposed by prominent Internet engineers. Dr. kahn fears that discouraging experimentation on the fringes of the net's architecture will compromise the development of the still "very fragile" Internet. He calls the neutrality issue a bigger threat to the health of the Internet than possible fragmentation.<ref>[http://www.theregister.co.uk/2007/01/18/kahn_net_neutrality_warning/ TheRegister.co.uk]</ref>
Robert is still very much working in a role focused on technological advancement and infrastructural development with the [[CNRI]], and has welcomed renewed government interest in infrastructural R&D within the context of the economic downturn.<ref>[http://gcn.com/Articles/2009/05/18/GCN-Interview-with-Robert-Kahn.aspx GCN.com]</ref>
Dr. Khan has been recently involved in [[Digital Object Architecture]], which aimed to create a network model whose main goal was to manage information, not switch packets as in the case of the Internet. An interview wherein Robert technically parses his current work can be found [http://gcn.com/Articles/2009/05/18/GCN-Interview-with-Robert-Kahn.aspx?Page=2 here].
He has said that further developing the Internet today is akin to “changing the wings and the engines on a flying aircraft without being able to ever land it”; though he claims that the research community must take a more active role in innovating on the Internet.<ref>[http://www.princeton.edu/engineering/news/archive/?id=804 Princeton.edu]</ref>
