The U.S. Department of Agriculture's Agricultural Research Service is planning to award a contract for the construction of a Science DMZ network. The department is one of a growing number of government agencies to develop these specialized networks for compute-intensive tasks.
Science DMZs are specialized systems that normally are located at or close to the agency's network perimeter and often tied directly to the router that connects the research institution to the wide-area network, guaranteeing the greatest possible network speed for science data.
Due to the smaller application set producing the data for the Science DMZ, firewalls could be eliminated by filtering the data through switches or routers based on Internet Protocol addresses or TCP ports, used together with intrusion-detection systems.
In addition, the Science DMZ needs data transfer nodes that are designed for science data transfer. These types of systems often use performance-focused Service Oriented Network monitoring ARchitecture (perfSONAR), which is a set of tools that can continually check for packet loss or increases in latencies across the network.
Although a Science DMZ can have many different designs, they all have components in common as well as the flexibility to incorporate emerging technologies.
