Google’s Network Scale

In google’s words:

Today at the 2015 Open Network Summit, we are revealing for the first time the details of five generations of our in-house network technology. From Firehose, our first in-house datacenter network, ten years ago to our latest-generation Jupiter network, we’ve increased the capacity of a single datacenter network more than 100x. Our current generation — Jupiter fabrics — can deliver more than 1 Petabit/sec of total bisection bandwidth. To put this in perspective, such capacity would be enough for 100,000 servers to exchange information at 10Gb/s each, enough to read the entire scanned contents of the Library of Congress in less than 1/10th of a second.

That’s quite a bandwidth. One can get more details about it in their Jupiter Rising paper which is being presented in SIGCOMM 15.
