Streamlining the Internet-Fiber Connection

There's more than one way to carry Internet protocol traffic on a wavelength-division multiplexing infrastructure

Streamlining the Internet-Fiber Connection

The rapidly growing popularity of the Internet is the key driver in communications today. Even conservative observers estimate that Internet traffic will double every six months for the next few years. That kind of buildup means that, before the end of next year, the United States will need a communications capacity just for the Internet of about 35 terabits per second--an order of magnitude more than is required by all the voice traffic in the world today.

To provide such capacity, how should the present networking infrastructure be developed? In answering that question, some matters of fact should be taken into account. Since every study of future communications patterns predicts that data traffic will continue to grow much more rapidly than voice, any new transport infrastructure should clearly be optimized for data. More specifically, since the Internet protocol (IP) is at the heart of so much revenue-generating activity in the world today and seems certain to become even more entrenched in the future, suggesting that the network should be optimized to carry IP traffic seems reasonable.

New AI Speeds Computer Graphics by Up to 5x

Neural rendering harnesses machine learning to paint pixels

Four examples of Nvidia's Instant NeRF 2D-to-3D machine learning model placed side-by-side.

Nvidia Instant NeRF uses neural rendering to generate 3D visuals from 2D images.

On 20 September, Nvidia’s Vice President of Applied Deep Learning, Bryan Cantanzaro, went to Twitter with a bold claim: In certain GPU-heavy games, like the classic first-person platformer Portal, seven out of eight pixels on the screen are generated by a new machine-learning algorithm. That’s enough, he said, to accelerate rendering by up to 5x.

This impressive feat is currently limited to a few dozen 3D games, but it’s a hint at the gains neural rendering will soon deliver. The technique will unlock new potential in everyday consumer electronics.
