Research community looks to SDN to help distribute data from the Large Hadron Collider

John Dix | May 27, 2015
Most advanced research and education networks have transitioned to 100 Gbps, but as fast as the core networks progress, the capabilities at the edge progress even faster.

The Energy Sciences Network (ESnet) reached 18 petabytes per month at the end of last year and the growth rate since 1992 is a factor of ten every four and a quarter years, which is a growth rate of 72% per year. The projection forward is an exabyte a month by about 2020 and 10 exabytes a month by about 2024.

In terms of individual flows, we can already do several tens of gigabytes per second in production and we can saturate 200 Gbps links (for example a 100 Gbps link bidirectionally) over long distances at will.
