#ARPAnet

You may have seen a "today in history"-type toot going around that talked about ARPAnet switching to the IP protocol, effectively being the birth of the internet. It was a long time ago.

And it made me realize that the internet per se was only 3 years old when I first experienced it.

Vor 43 Jahren: Wie TCP/IP aus ARPANET das Internet machte
Am 1. Januar 1983 startete ein Protokollwechsel, der das Fundament für das heutige Internet legte. ARPANET stellte schrittweise vom Network Control Program (NCP) auf TCP/IP um.

Happy birthday to the Internet!

On this day in 1983, the ARPANET network officially switched to using the TCP/IP protocol, effectively creating the Internet. usg.edu/galileo/skills/unit07/

CENI - La Chine vient de mettre en service l'héritier d'ARPANET

fed.brid.gy/r/https://korben.i

<p>Vous vous souvenez d'<strong>ARPANET</strong>, ce réseau militaire américain des années 60-70 qui a donné naissance à Internet ? En 2006, les États-Unis ont remis le couvert avec GENI, un autre réseau de recherche afin de tester les technologies futures du web et qui a fonctionné durant plus d'une décennie avant de s'éteindre progressivement jusqu'en 2023.</p>
<p>Et aujourd'hui, devinez qui vient de prendre le relais ?</p>
<p>La Chine, évidemment !</p>
<p>Le pays vient en effet d'annoncer la mise en service officielle de <strong>CENI</strong>, pour China Environment for Network Innovation, qui est ni plus ni moins que la première infrastructure nationale chinoise dédiée à l'innovation dans les technologies réseau. Et les specs font un peu peur je dois dire...</p>

</p>
<p>Il s'agit d'un réseau qui relie 40 villes chinoises via plus de 55 000 km de fibre optique et qui a nécessité plus de 10 ans de construction. Le truc est capable de supporter 128 réseaux hétérogènes simultanément et de mener 4 096 tests de services en parallèle... Niveau chiffres, c'est assez costaud.</p>

Das #ARPANet, der Vorgänger des #Internet, wurde mal entwickelt, um im Kriegsfalle einen kompletten #Systemausfall durch Ausfall von Teilsystemen zu verhindern. Das Routing setzt dann dynamisch andere Wege um, so dass das verbleibende Netz ungestört weiter machen kann.

Gestern musste ich sehr dringend noch einen
#Kickstarter, an dem ich teilgenommen habe, mit einem Eintrag im #Bakerkit finalisieren.

Auf beide Services konnte ich nicht zugreifen, weil eine kryptische Meldung des Services
#Cloudflare mir dies verweigerte.

"Das Internet" ist irgendwann total falsch abgebogen, als Services auf einmal alle zentralisiert wurden..

There's a mantra about the importance of redundancy that originated a long time ago in the military but applies in many contexts, including system and network administration.

"Two is one, and one is none." 🖥️ 🖥️

It's the design concept of the Internet itself—when it was still called "ARPANET". The idea was that in the event of a nuclear strike where a large part of the country was wiped off the face of the Earth, surviving systems and 'inter-networks' in other geographical regions would still be able to communicate with each other with little or no manual reconfiguration.

Resilience in the wake of failure was the goal, communication was to be ensured at all costs.

RAID, failover WAN, BGP (and TCP/IP routing in general), server clustering all mitigate downtime in the event of failure of a single component (or even scheduled maintenance where pieces must be taken offline).

It's a practice that I won't say I'm *obsessed* over, but I absolutely enjoy employing it wherever I can, even if it seems overkill. ✅ 💙 😎 Call it my inner-prepper, I dunno 😂

On in 1969, , a US military project and the precursor the , established the first successful host-to-host link between computers. A pioneer in packet switching networks, ARPANET made possible the interconnected world we all now share.

The actual first message that was sent that day was just "LO", first two letters of the word "LOGIN", when the system crashed.

A portion of an interview from the linked website:

Did you realise this could be a historic moment?

Kline: No, I certainly didn't at that time.

Duvall: Not really. It was another step forward in the larger context of the work we were doing at SRI which we did believe would have a large impact.

When Samuel Morse sent the first telegraph message in 1844, he had an eye for drama, tapping out "What hath God wrought" on a line from Washington, DC to Baltimore, Maryland, US. If you could go back, would you have typed something more memorable?

Kline: Of course, if I had realised its importance. But we were just trying to get it to work.

On this day, 56 years ago:

"At 10:30 p.m., 29 October 1969, the first ARPANET message was sent from this UCLA site to the Stanford Research Institute."

A black commemorative plaque with gold frame, inscribed with gold letters. It reads:

"At 10:30 p.m., 29 October 1969, the first ARPANET message was sent from this UCLA site to the Stanford Research Institute. Based on packet switching and dynamic resource allocation, the sharing of information digitally from this first node of ARPANET launched the Internet revolution."

Primera comunicación entre dos ordenadores (ARPANET) NACE INTERNET

ARPANET, nacida a finales de los años 60 como un proyecto del Departamento de Defensa de Estados Unidos, fue la primera red operativa que sentó las bases de Internet. Su objetivo principal era conectar ordenadores de investigación en distintas universidades y centros militares para compartir información y recursos de forma fiable y descentralizada, de modo que la red pudiera sobrevivir incluso en caso de ataques o fallos parciales.

La tecnología clave de ARPANET fue la conmutación de paquetes, que divide los datos en pequeños bloques denominados paquetes. Estos paquetes viajan independientemente por diferentes rutas y se vuelven a ensamblar en el destino. Esto permite una utilización más eficiente de los recursos y mayor resistencia de la red, ya que los paquetes pueden redirigirse si una ruta está dañada o congestionada.

Los nodos de la red estaban conectados mediante dispositivos llamados IMP (Interface Message Processors), que actuaban como predecesores de los actuales routers, organizando, transmitiendo y reenviando los paquetes.

Inicialmente, ARPANET utilizó el Protocolo de Control de Red (NCP), pero luego adoptó el protocolo TCP/IP, desarrollado a mediados de los 70, que permitió la comunicación fiable y el direccionamiento de paquetes a través de múltiples redes, estableciendo el estándar para Internet.

El 29 de octubre de 1969, ARPANET logró la primera comunicación entre dos ordenadores, en UCLA y el Stanford Research Institute, enviando inicialmente las letras «lo» de la palabra «login» antes de completar el mensaje, un hito considerado el nacimiento de Internet.

Así, ARPANET se convirtió en la base técnica y conceptual desde la que evolucionó la Internet global, cambiando la forma en que el mundo comunica y comparte información.ninjaone+8

There are a few well known hand drawn maps of the early ARPANet. Are there any of UUCPNet from a similar period?

I know there were nodes that acted as gateways between the two networks.

🌘 解鎖能供 AI 使用的千萬倍數據:ARPANET 式計畫有望解決數據可及性問題
➤ 透過創新框架與 ARPANET 式的集體努力,打破數據孤島,為 AI 注入強勁動能
ifp.org/unlocking-a-million-ti
人工智慧的飛躍式發展,一向伴隨著訓練數據的爆炸性增長。然而,如今業界領袖卻憂心 AI 已達「數據高峯」,訓練用數據枯竭。本文分析指出,這或許是因數據並非真的稀缺,而是可及性出了問題。現今頂尖 AI 模型僅使用了數百 TB 的數據,相較於全球已數位化、但未被用於訓練的估計 180-200 ZB 數據,這僅是九牛一毛。作者提出「基於歸因的控制 (ABC)」框架,旨在讓數據所有者在保有控制權的同時,能促進 AI 發展。為瞭解決技術、法律和經濟障礙,作者建議仿效 ARPANET 的成功經驗,推動一項政府主導的計畫,以釋放千萬倍的數據潛力。
+ 這篇文章點出了 AI 發展的關鍵瓶頸,數據的可及性確實比絕對數量更為重要。ABC 框架聽起來很有潛力,
