Leonard kleinrock contribution to the internet

His work and college training were invaluable, and led to his winning a full graduate fellowship to attend the Massachusetts Institute of Technology in the Electrical Engineering Department. At MIT, he found that the vast majority of his classmates were doing their Ph. This was not for him, and instead he chose to break new ground in the virtually unknown area of data networks.

Indeed, in Mayhe submitted a Ph. In April, he published the first paper to introduce the concept of breaking messages into smaller fixed-length pieces eventually to be named "packets". In this work, he developed the basic principles of packet switching, thus providing the fundamental underpinnings for that technology. These principles along with his subsequent research continue to provide a basis for today's Internet technology.

Kleinrock is arguably the world's leading authority and researcher in the field of computer network modeling, analysis and design and a father of the Internet. But the commercial world was not ready for data networks and his work lay dormant for most of the 's as he continued to publish his results on networking technology while at the same time rising rapidly through the professorial ranks at UCLA where he had joined the faculty in ARPA had been supporting a number of computer scientists around the country and, as new researchers were brought in, they naturally asked ARPA to provide a computer on which they could do their research; however, ARPA reasoned that this community of scientists would be able to share a smaller number of computers if these computers were connected together by means of a data network.

Because of his unique expertise in data networking, they called him to Washington to play a key role in preparing a functional specification for the ARPANET - a government-supported data network that would use the technology which soon came to be known as "packet switching". It was their job to take the specification and develop a computer that could act as the switching node for the packet-switched ARPANET.

BBN had selected a Honeywell minicomputer as the base on which they would build the switch. This was a challenging task since no such connection had ever been attempted. This minicomputer had just been released in and Honeywell displayed it at the Fall Joint Computer Conference where Kleinrock saw the machine suspended by its hooks at the conference; while running, there was this brute whacking it with a sledge hammer just to show it was robust.

As it turns out, BBN was running two weeks late much to Kleinrock's delight, since he and his team badly needed the extra development time ; BBN, however, shipped the IMP on an airplane instead of on a truck, and it arrived on time Saturday, August 30, Aware of the pending arrival date, Kleinrock and his team worked around the clock to meet the schedule.

At the end of the holiday weekend after the IMP arrived i. Expectations and anxieties were high because, everyone was concerned that their piece might fail.

By the next day they had messages moving between the machines. Kleinrock refers to that day, September 2,as the day the infant Internet took its first breath of life. The procedure was to type in "log" and the system at SRI was set up to be clever enough to fill out the rest of the command, namely to add "in" thus creating the word "login".

A telephone headset was mounted on the programmers at both ends so they could communicate by voice as the message was transmitted. Skip to primary content. Leonard Kleinrock defines packet switching.

Chapter Two: In the Air. Baran said. It's just this one little case that seems to be an aberration. The NPL group influenced a number of American computer scientists in favor of the new technique, and they adopted Davies's term "packet switching" to refer to this type of network.
