Science DMZ diagram

AARNet is developing services based on the Science DMZ architecture, in order to support big science research occurring at research institutions connected to the AARNet network.

Brought to us by ESnet, the US Department of Energy research network, the basic premise is to divert large flows of data around the institutional firewall and through a secure yet highly tuned Data Transfer Node (DTN). This 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 means that simpler security can be used, and that institutions don’t require the same investment in high-end firewalls as is required to protect most end-users, so money can be saved, too.
