35th Anniversary of the Internet UCLA October 29, 2004 TheThe BigBig BangBang !! (or(or thethe birthbirth ofof thethe Internet)Internet) by Leonard Kleinrock 1989 • It was back in '67 that the clan agreed to meet. • The gangsters and the planners were a breed damned hard to beat. • The goal we set was honest and the need was clear to all: • Connect those big old mainframes and the minis, lest they fall.

• The spec was set quite rigid: it must work without a hitch • It should stand a single failure with an unattended switch. • We decided UCLA would be first node on the net • As the best researchers out there, we would be the perfect bet.

th  Leonard Kleinrock 2004 35 ANNIVERSARY of the INTERNET @ UCLA TheThe BigBig BangBang !!

• I suspect you might be asking "What means FIRST node on the net?" • Well frankly, it meant trouble, 'specially since no specs were set. • For you see the interface between the nascent IMP and HOST • Was a confidential secret from us folks on the West coast.

• BBN had promised that the IMP was running late. • We welcomed any slippage in the deadly scheduled date. • But just ahead of Labor Day, it was plopped down at our gate! • Those dirty rotten scoundrels sent the damned thing out air freight!

th  Leonard Kleinrock 2004 35 ANNIVERSARY of the INTERNET @ UCLA TheThe BigBig BangBang !!

• As I recall that Tuesday, it makes me want to cry. • Everybody's brother came to blame the other guy! • Folks were there from ARPA, BBN and Honeywell. • UCLA and ATT and all were scared as hell.

• We cautiously connected and the bits began to flow. • The pieces really functioned - just why I still don't know. • Messages were moving pretty well by Wednesday morn. • All the rest is history - packet switching had been born!

In ARPA, the Program Plan is the master document describing a major program. This plan, which I wrote in 1968, had the following concepts:

1. Objectives – Develop Networking and Resource Sharing 2. Technical Need – Linking Computers 3. Military Need – Resource Sharing - Not Nuclear War 4. Prior Work – MIT-SDC experiment 5. Effect on ARPA – Link 17 Computer Research Centers, Network Research 6. Plan - Develop IMP’s and start 12/69 7. Cost – $3.4 M for 68-71

Each distinct network had to stand on its own, and no internal changes could be required of any such network before being connected to the Internet. 2. Communications would be on a best-effort basis. If a packet didn’t make it to the final destination, it would quickly be retransmitted from the source. 3. Black boxes (later called gateways and routers) would be used to connect the networks. No information would be retained by the gateways about individual flows of packets passing through them, keeping them simple and avoiding complicated adaptation and recovery from various failure modes. 4. There would be no global control at the operations level. th  Leonard Kleinrock 2004 35 ANNIVERSARY of the INTERNET @ UCLA GrowthGrowth ofof thethe InternetInternet •• 19731973 CerfCerf andand KahnKahn designdesign TCPTCP •• 19731973 ARPAARPA deploysdeploys SATNETSATNET –– 11st internationalinternational connectionconnection •• 19731973 BobBob MetcalfeMetcalfe developsdevelops EthernetEthernet ideaidea •• 19741974 CerfCerf andand KahnKahn publishpublish TCPTCP specificationspecification •• 19751975 ARPANETARPANET mgtmgt transferstransfers toto DCADCA •• 19781978 TCPTCP splitssplits intointo TCPTCP andand IPIP drivendriven byby DannyDanny Cohen,Cohen, DavidDavid ReedReed andand JohnJohn SchochSchoch toto supportsupport realreal--timetime traffic.traffic This allows the creation of UDP. •• 19801980 CSNETCSNET isis fundedfunded byby NSFNSF inin responseresponse toto aa proposalproposal byby LarryLarry LandweberLandweber,, DaveDave Farber,Farber, TonyTony HearnHearn andand PeterPeter DenningDenning

THE DEADLINE HAS BEEN ANNOUNCED. The Green Card Lottery is a completely legal program giving away a certain annual allotment of Green Cards to persons born in certain countries. The lottery program was scheduled to continue on a permanent basis. However, recently, Senator Alan J Simpson introduced a bill into the U. S. Congress which could end any future lotteries. THE 1994 LOTTERY IS SCHEDULED TO TAKE PLACE SOON, BUT IT MAY BE THE VERY LAST ONE. PERSONS BORN IN MOST COUNTRIES QUALIFY, MANY FOR FIRST TIME. The only countries NOT qualifying are: Mexico; India; P.R. China; Taiwan, Philippines, North Korea, Canada, United Kingdom (except Northern Ireland), Jamaica, Domican Republic, El Salvador and Vietnam. Lottery registration will take place soon. 55,000 Green Cards will be given to those who register correctly. NO JOB IS REQUIRED. THERE IS A STRICT JUNE DEADLINE. THE TIME TO START IS NOW!!
