Science DMZ Support for Advanced and Emerging Services
The Science DMZ provides the ideal entry point into a research institution for advanced networking services available in the wide area, such as virtual circuits and software-defined networking. If the Science DMZ is built properly with capable equipment and is free of the restrictions that come with the support of general-purpose business connectivity needs, it is typically straightforward to allow local resources in the Science DMZ to take advantage of advanced wide area network services.
Virtual circuit services, such as the ESnet-developed OSCARS platform, can connect to the Science DMZ switch directly, or by connecting a separate switch as needed. The campus or lab’s interdomain controller (IDC) can provision the local switch and initiate multi-domain wide area virtual circuit connectivity to enable the Data Transfer Nodes or other Science DMZ resources to access science services at remote institutions. An example of this configuration was the NSF-funded Internet2 DYNES project that is supporting the deployment of this architecture in 60+ university campuses across the U.S.
100 Gigabit Ethernet
100 Gigabit Ethernet (GE) technology is being deployed by science networks in the U.S. and internationally to support data-intensive science. While 100GE promises the ability to support next-generation instruments and facilities, and to conduct scientific analysis of distributed data sets at unprecedented scale, 100GE technology poses significant challenges for the general-purpose networks at research institutions. For example, the firewalls typically deployed in business environments are simply incapable of effectively supporting 100GE science services. The Science DMZ model provides a scalable, expandable platform for integrating 100GE services into the science mission of a research institution. The 100GE service can be connected directly to the Science DMZ to provide a "fast path" between the science resources deployed in the Science DMZ and the advanced services provided by science networks.
