Science DMZ

The problem 10

Science DMZ 11 MotivationsMotivations “Friction free networking” 2. Dedicated systems for data transfer 3. Performance and network measurement tools 4. Security mechanisms designed for high performance 1. Network architecture for high performance applications

Science DMZ 12 Current university connection

Science DMZ 13 University connection with S-DMZ

Science DMZ 14 BenefitsBenefits Usability: Software tools to enable high-speed data transfer Performance: Improve performance for data-intensive research Maximise investment in AARNet connection Improve general traffic by offloading “elephant flows” High-speed access to cloud resources (RDSI, AWS, …) Cost: Delay expensive firewall upgrades High-speed switches, rather than expensive routers Security: Layered security, applied on both network and host Firewalled traffic is to a known destination (Data Transfer Node) Integration with AARNet4 private VPN services
