Science DMZ is a portion of the network that is built at or near the campus or laboratory’s local network perimeter. It is designed in a way that the equipment, configuration and security policies are optimised for high-performance scientific applications rather than general-purpose business systems or ‘enterprise’ computing.

Science DMZ was developed by ESnet engineers. It addresses common network performance problems encountered by research institutions by creating an environment that is tailored to the needs of high performance science applications, including high-volume bulk data transfer, remote experiment control and data visualisation.

Science DMZs are scaleable, incrementally deployable and easily adaptable to incorporate emerging technologies.

Capabilities and features

Science DMZs addresses several key issues in data intensive science, including:

  • Reducing or eliminating the packet loss that causes poor TCP (Transmission Control Protocol) performance
  • Implementing appropriate security architectures and controls so that high performance applications are not hampered by unnecessary constraints
  • Providing an on-ramp for local science resources to access wide area science services including virtual circuits, SDN environments and 100 gigabit infrastructures
  • Incorporating network testing, network measurement and performance analysis through the deployment of perfSONAR (link to perfSONAR)

Who can use this service
