Science DMZ

A solution for speeding up big data transfers

Moving research data faster

Advances in networking technologies are making moving research data around over the network easier and "sneakernet" - ie, moving research data around on portable hard drives - a thing of the past.  

AARNet offers network services based on the Science DMZ architecture, in order to support data-intensive research at institutions connected to the AARNet network. 

The Science DMZ was developed by ESnet, the US Department of Energy research network. This system diverts large flows of data around the institutional firewall and through a secure yet highly tuned Data Transfer Node (DTN). The DTN performs data transfer on behalf of users. We call this ‘friction-free networking’.

The system improves performance for both ‘big data’ users and regular users of the network, as the heavy lifting of scientific networking no longer shares the same firewall as the rest of the network.

This also means that network security for high-performance science purposes can be deployed without the constraints and heavy investment that comes with protecting general-purpose users of the network.



Additional benefits of the Science DMZ solution:

  • Scalable
  • Incrementally deployable
  • Easily adaptable to incorporate emerging technologies such as 100 Gigabit ethernet services, virtual circuits, and software-defined networking capabilities.
  • Network testing, network measurement, and performance analysis are incorporated through the deployment of perfSONAR
