Network architecture for high performance applications 2. Dedicated systems for data transfer 3. Performance and network measurement tools 4. Security mechanisms designed for high performance 11 AARNet Copyright 2014 Current university connection University campus Border router AARNet PE Enterprise firewall Site/Campus LAN APL-NTU To other R&E destinations or the internet All flows pass through firewall, impacting performance 12 Data-intensive resources - Staff - Students - Instruments - Compute/storage - etc AARNet Copyright 2014 University connection with S-DMZ To other R&E destinations or the internet University campus Border router AARNet PE Enterprise firewall Site/Campus LAN APL-NTU Clean, high-bandwidth path to/from WAN Site/campus access to Science DMZ resources Per-service security policy control points Data-intensive resources Border Edge Switch/router Science DMZ 13 Data Transfer Node with high-speed storage - Staff - Students - Instruments - Compute/storage - etc AARNet Copyright 2014 Benefits Performance: Improve performance for data-intensive research Improve general traffic by offloading “elephant flows” High-speed access to cloud resources (RDSI, AWS, …) 14 Usability: Software tools to enable high-speed data transfer Integration with AARNet4 private VPN services Cost: Delay expensive firewall upgrades Maximise investment in AARNet connection 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) AARNet Copyright 2014 DaShNet AARNet Copyright 2014 RDSI : high speed network connectivity Primary Node Secondary Node AARNet 4 Routed Access Inter-node VPN “Enabling researchers to use, reuse and manipulate significant data collections” 16 AARNet Copyright 2014 RDSI & Science DMZ AARNet backbone network APL APL NAP #1 RDSI Node Node PerfSonar 1 PerfSonar 2 BES-1 AARNet Layer 3 PE1 DTN 1 Node network infrastructure APL-NTU1 Node Storage DTN 2 Inter-Node VPN PE2 APL-NTU2 BES-2 APL NAP #2 17 AARNet Copyright 2014 PerfSonar 18 AARNet Copyright 2014 DTN : Aspera + Globus Online 19 AARNet Copyright 2014 Software Defined Networking AARNet Copyright 2014 Traditional vs. SDN Network management applications Network device Network OS Network device Network OS Network device Network OS Network device Network OS Traditional Network 21 21 AARNet Copyright 2014 Traditional vs. SDN Application layer Network management applications API Business applications Controller layer Network OS Network device Network services Network device API Network OS Network OS Infrastructure layer Network device Network device Network OS Network device Network device Network OS Traditional Network 22 Network device Network device Network device SDN Network AARNet Copyright 2014 AARNet SDN Testbed 23 AARNet Copyright 2014 AARNet SDN Testbed Researchers SDN lab Researchers Researchers Researchers SDN lab SDN lab SDN lab 24 AARNet Copyright 2014 Thank You
