WEBVTT 00:00:01.291 --> 00:00:05.370 (electronic music) 00:00:05.370 --> 00:00:07.670 - [Narrator] Computer scientist Leonard Kleinrock 00:00:07.670 --> 00:00:10.540 arrived at UCLA in 1963 00:00:10.540 --> 00:00:13.750 fresh from receiving his PhD from MIT. 00:00:13.750 --> 00:00:15.990 Kleinrock's research was on data networking 00:00:15.990 --> 00:00:17.840 and packet switching. 00:00:17.840 --> 00:00:20.020 - Well, the underlying technology of the internet 00:00:20.020 --> 00:00:21.610 is packet switching. 00:00:21.610 --> 00:00:25.010 That's the way your messages, your videos, your voice, 00:00:25.010 --> 00:00:27.280 your pictures, your data are transmitted 00:00:27.280 --> 00:00:29.720 in little chunks called packets. 00:00:29.720 --> 00:00:32.359 So a long messages broken up into smaller packets, 00:00:32.359 --> 00:00:36.010 each packet is addressed and sent through the network 00:00:36.010 --> 00:00:39.428 like a bunch of postcards carrying a long letter 00:00:39.428 --> 00:00:42.920 independently making their way through the network 00:00:42.920 --> 00:00:45.893 arriving at the other end, being put back together again 00:00:45.893 --> 00:00:48.090 and delivered to you as an entity, 00:00:48.090 --> 00:00:49.663 as a longer message. 00:00:50.940 --> 00:00:52.350 - [Narrator] In the late 1960s 00:00:52.350 --> 00:00:54.550 the Advanced Research Project Agency 00:00:54.550 --> 00:00:57.622 decided that UCLA under Kleinrock's leadership 00:00:57.622 --> 00:01:00.112 would become the first node of the ARPANET, 00:01:00.112 --> 00:01:02.740 a fledgling network of computers connected 00:01:02.740 --> 00:01:06.400 to various research universities across the country. 00:01:06.400 --> 00:01:10.130 The first switch known as an interface message processor 00:01:10.130 --> 00:01:13.590 arrived on Labor Day weekend, 1969. 00:01:13.590 --> 00:01:16.860 The switch was connected to a host computer at UCLA 00:01:16.860 --> 00:01:18.863 on September 2nd. 00:01:18.863 --> 00:01:21.440 - You might say at September 2nd 00:01:21.440 --> 00:01:25.600 that infant internet, that one node 00:01:25.600 --> 00:01:29.227 took its first breath of life in that it was born 00:01:29.227 --> 00:01:31.200 and met the outside world 00:01:31.200 --> 00:01:33.970 which was in the form of our time-shared computer. 00:01:33.970 --> 00:01:36.143 But one node does not make a network. 00:01:37.190 --> 00:01:38.080 - [Narrator] One month later, 00:01:38.080 --> 00:01:39.650 a second switch was delivered to 00:01:39.650 --> 00:01:41.832 Stanford Research Institute. 00:01:41.832 --> 00:01:45.510 Then on October 29th, 1969, 00:01:45.510 --> 00:01:49.490 right here at UCLA on the 3rd floor of Boelter Hall 00:01:49.490 --> 00:01:51.970 Kleinrock's group attempted to log into the node 00:01:51.970 --> 00:01:54.400 at Stanford Research Institute. 00:01:54.400 --> 00:01:57.033 This would be the first message sent on the internet. 00:01:57.033 --> 00:02:01.880 - Now to login we have to type L-O-G 00:02:01.880 --> 00:02:03.503 and the remote computer is smart enough 00:02:03.503 --> 00:02:04.670 to know what we're trying to do. 00:02:04.670 --> 00:02:06.003 It types the I-N for us. 00:02:07.630 --> 00:02:11.550 So I had Charlie Klein at my end and Mr. Duval 00:02:11.550 --> 00:02:13.540 at the other end, programmers, 00:02:13.540 --> 00:02:16.010 and instructed Charlie to type in the L-O-G 00:02:16.010 --> 00:02:18.640 and he had a telephone connection with Duval. 00:02:18.640 --> 00:02:20.437 So Charlie typed L, he said, 00:02:20.437 --> 00:02:21.767 "Did you get the L?" 00:02:21.767 --> 00:02:23.370 "Yep, got the L." 00:02:23.370 --> 00:02:25.467 Typed the O, "Got the O?" 00:02:25.467 --> 00:02:26.430 "Got the O." 00:02:26.430 --> 00:02:27.405 Typed the G, "Get the G?" 00:02:27.405 --> 00:02:29.150 (clap hands) Crash! 00:02:29.150 --> 00:02:31.510 The SRI computer crashed. 00:02:31.510 --> 00:02:36.320 So the first message ever on the internet was lo. 00:02:36.320 --> 00:02:38.555 As in, lo and behold. 00:02:38.555 --> 00:02:41.130 We didn't plan it but we could not have come up with 00:02:41.130 --> 00:02:42.610 a better message. 00:02:42.610 --> 00:02:46.293 Short, prophetic, planning what the future would be. 00:02:47.200 --> 00:02:48.930 - [Narrator] In the early days of the internet. 00:02:48.930 --> 00:02:51.300 Kleinrock directed the Network Measurement Center 00:02:51.300 --> 00:02:53.030 at UCLA Engineering, 00:02:53.030 --> 00:02:55.130 designed to test, measure and stress 00:02:55.130 --> 00:02:57.520 the limits of the emerging network. 00:02:57.520 --> 00:02:59.600 - We tried to break the network. 00:02:59.600 --> 00:03:02.350 We sent lots of traffic to individual sites. 00:03:02.350 --> 00:03:04.870 We sucked up a lot of traffic ourselves. 00:03:04.870 --> 00:03:09.370 We basically tried to send strange messages, heavy messages, 00:03:09.370 --> 00:03:11.850 to test the outer envelope of the network. 00:03:11.850 --> 00:03:13.090 That was our job. 00:03:13.090 --> 00:03:13.923 And we did. 00:03:13.923 --> 00:03:16.050 We found that just what the network was capable of, 00:03:16.050 --> 00:03:17.069 where it would break, 00:03:17.069 --> 00:03:20.291 what we would need to extend its capabilities. 00:03:20.291 --> 00:03:22.686 - [Narrator] In 45 years at UCLA, 00:03:22.686 --> 00:03:26.590 Leonard Kleinrock has graduated 47 PhD students 00:03:26.590 --> 00:03:28.340 and more are still in the pipeline. 00:03:29.177 --> 00:03:33.933 - Getting a PhD is learning how to do research. 00:03:34.860 --> 00:03:38.030 And so, as their mentor, as their supervisor 00:03:38.030 --> 00:03:40.830 it's my responsibility to make sure they have 00:03:40.830 --> 00:03:43.630 the right approach to doing research. 00:03:43.630 --> 00:03:45.250 We must teach our students 00:03:45.250 --> 00:03:47.820 to take a longterm view on research, 00:03:47.820 --> 00:03:50.650 not a short-term, narrow view, 00:03:50.650 --> 00:03:54.210 but a longterm, broad view, innovative, 00:03:54.210 --> 00:03:56.313 dangerous and exciting. 00:03:57.250 --> 00:03:59.850 That's the kind of mentality you want to carry on 00:03:59.850 --> 00:04:01.463 generation after generation. 00:04:02.400 --> 00:04:03.530 - [Narrator] For his pioneering work 00:04:03.530 --> 00:04:06.320 on the technological foundation of the internet 00:04:06.320 --> 00:04:07.930 and for mentoring generations 00:04:07.930 --> 00:04:10.420 of outstanding computer scientists, 00:04:10.420 --> 00:04:13.350 Leonard Kleinrock received the National Medal of Science 00:04:13.350 --> 00:04:15.560 in September, 2008. 00:04:15.560 --> 00:04:18.223 The metal is the nation's highest scientific honor. 00:04:19.070 --> 00:04:23.080 For more than 40 years, UCLA professor Leonard Kleinrock 00:04:23.080 --> 00:04:27.500 has been a leader, an innovator, a scholar and a mentor 00:04:27.500 --> 00:04:29.600 in the computer science field. 00:04:29.600 --> 00:04:32.700 His pioneering internet work at UCLA Engineering 00:04:32.700 --> 00:04:36.143 has a global reach and will have a long-lasting impact. 00:04:38.540 --> 00:04:41.310 The UCLA Henry Samueli School of Engineering 00:04:41.310 --> 00:04:44.433 and Applied Science, the birthplace of the internet. 00:04:45.327 --> 00:04:48.660 (electronic music ends)
