Kecepatan Internet 48 Mbps Sudah Biasa, Kalau 91 Gbps seperti NASA??


Mendengar kecepatan akses internet mencapai 91 Mbps sudah membuat mata kita berbinar, tetapi akses internet mencapai 91 Gbps (gigabit per detik) sudah pasti membuat rahang kita jatuh. Kapankah impian seperti NASA terwujud untuk umum? Berikut penjelasan dari personil NASA seperti dimuat di quora.com.

NASA has 91 Gbps internet Speed
JULY 4, 2014 By Honey

We all know about that Google provide 10 Gigabit per second Internet speed with its Google Fiber. Which is 1000 times faster than the Internet now we use at our homes. W0w its so fast.

But for NASA this speed is nothing, did you know the speed of Internet at NASA’s headquarter of course not. The transfer speed at NASA’s headquarter is about 91 Gigabit per second. Which is 100 times faster than Google Fiber.

NASA's Internet connection is 13,000 times faster than yours

If there’s one organization that never has to worry about streaming videos in glorious HD, it’s NASA. The space organization's shadow network can transfer 91 gigabits per second, or 91,000 megabits per second.

For comparison, the average broadband connection speed in the U.S. is 6.6 megabits per second - or more than 13,000 times slower.

NASA’s Shadow Internet: 100 Times Faster Than Google Fiber
By Meghan Coyle
June 19, 2014

NASA uses a super-fast shadow network, known as the Energy Science Network (ESnet for short), to connect researchers working on big data projects, such as the Large Hadron Collider or the Human Genome Project. ESnet uses fiber optic lines to reach transfer speeds of 91 gigabits per second, the fastest ever reported for end-to-end data transfer conducted under real world conditions. NASA does not plan on making ESnet available to consumers, but the tech may someday be picked up by Internet service providers.

Konfirmasi dari personil NASA

Beredarnya berita tersebut tak ayal membuat gerah beberapa orang yang memahami apa yang sebenarnya terjadi. Robert Frost, Instructor and Flight Controller di Flight Operations Directorate, NASA meluruskan hal ini melalui blognya di quora.com pada tanggal 23 November 2014 sebagai berikut:

Once again, poor journalism strikes.

Contrary to numerous blog reports last summer, the Internet speed at NASA is not 91 gigabits per second. That speed was achieved on a specific connection between SC13 in Denver and the NASA Goddard facility in Maryland during an experiment. The experiment utilized the ESnet, which allows site to site file transfer at up to 100 gigabits per second, for two sites connected via ESnet. It does not relate to regular internet access, at all.

Here is a detailed presentation about the experiment: http://science.gsfc.nasa.gov/606.1/HECN-highlights/SC13-report.pdf


Tanpa perlu menunggu lama, Sekoci segera membuka tautan yang disertakan. Judulnya adalah:

Results From
NASA High End Computing (HEC)
WAN File Transfer Experiments/Demonstrations
Super Computing 2013 (SC13)

Overview-nya menjelaskan sebagai berikut:
These SC13 Network Research Exhibition (NRE) demonstrations were designed to showcase capabilities for transporting extremely large scale data for petascale scientific research using 100 Gbps long distance Wide Area Networks (WANs) and Local Area Networks (LANs).

Jadi, 91 Gbps BUKAN kecepatan internet di NASA, tetapi kecepatan INTRANET dengan menggunakan jalur khusus antara SC13 di Denver dan fasilitas Goddard di Maryland. Ini pun dalam rangka percobaan. Misinformasi terjadi karena ketidakpahaman pembuat berita dalam memahami laporan NASA.
