Managed Science DMZ

A solution for speeding up big data transfers

Moving research data faster

Science DMZ is a managed service designed to support the demands of data-intensive research at institutions connected to the AARNet network.

Science data transfer applications have unique network requirements that increasingly can’t be met by networks that are optimized for normal business operations like web browsing and business systems.

The Science DMZ architecture separates science traffic from general-purpose traffic, diverting 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.

Why Science DMZ?

  • Scientific network no longer shares the same firewall as the rest of the network. 
  • Optimised network for geographically-distributed, data-intensive resources.
  • Mitigates impact of the exponential growth in scientific data volumes on institutional network performance.
  • Improves performance for both big data science users and regular users of the network. 
  • Equipment and configuration of a Science DMZ ensures the network handles high-rate flows without dropping packets. 
  • Network security and access policies can be tailored for high-performance science purposes. 
  • 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.
