The First Two Packets on the Internet
Leonard Kleinrock
Kleinrock 是一名工程師和計算機科學(xué)家,他在APRANET網(wǎng)絡(luò)中起到了至關(guān)重要的角色。
He played an influential role in the development of the ARPANET, the precursor to the Internet, at UCLA.他早期研究Packet Switching的相關(guān)機制,在1964年他出版了一本書,內(nèi)有一句是這樣說的:
"Basically, what I did for my PhD research in 1961–1962 was to establish a mathematical theory of packet networks..."他發(fā)送了APRANET網(wǎng)絡(luò)的第一條信息:lo,“at 10:30 p.m, on October 29, 1969”,他打了一個電話給朋友,并使用一臺很大的SDS Sigma 7電腦(我更愿意稱它為機器),發(fā)送了“l(fā)ogin”這條信息。l和o成功的發(fā)送了,但是當(dāng)機器傳輸?shù)絞的時候,崩潰了,所以通過APRANET的第一條信息是lo。
他的助手幫忙記錄下了當(dāng)時的時間和地點,以及發(fā)生的一切,這是唯一的人為記錄。
對Katie Hafner的采訪
Hafner 是紐約時報的主編,主要撰寫科技方面的文章。她是NSFNET和ARPANET歷史發(fā)展的見證者。
她曾經(jīng)采訪過Ray Tomlinson,小老鼠@的發(fā)明者。有關(guān)小老鼠@
她與Jon Postel曾經(jīng)共處過很長的一段時間,Jon Postel 是發(fā)明互聯(lián)網(wǎng)的功臣之一,非常偉大的人物,協(xié)議發(fā)明大師。從他的發(fā)明可見一斑:
令我難以忘懷的是這樣一段話:
·In fact, when I was working on the book I sent him an email. I will never forget this, I think I don't have the email anymore. And I said, just out of curiosity, why haven't you ever wanted to get rich? Because that's when people were just starting to get rich, so this was in '95. And he said, it just, it's just not what this is about. Isn't that a wonderful thing? ·It is. ·Yeah, and that's who Jon was.2016/7/19
