  1. Internet2 Dynamic Circuit Servicesand Tools Andrew Lake, Internet2July 15, 2007JointTechs, Batavia, IL

  2. What to expect… • Internet2 Network • What is a “dynamic circuit”? • Why dynamic circuits? • Who do dynamic circuits help? • How do I connect? • Software • What do I need to get started?

  3. Internet2 “DCS” Network and HOPI I2 DCS: Ciena CoreDirector I2 HOPI: Force10 E600 10 Gigabit Ethernet 10 Gigabit Ethernet 10 Gigabit Ethernet OC192 SONET/SDH 1 Gigabit Ethernet or SONET/SDH 1 Gigabit Ethernet

  4. What is an Internet2 “dynamic circuit”? • User initiated (via software) setup of: • Point to Point Ethernet VLAN (HOPI) • Point to Point Ethernet (VLAN) Framed SONET Circuit (DCS) • Point to Point SONET Circuit (DCS) • Bandwidth provisioning available in 50 Mbps increments on DCS network

  5. Why dynamic circuits? • Benefits: • Guaranteed Bandwidth • Fast setup time • Resource reservation and allocation done automatically • Traffic Engineering • Monetary cost of equipment (Layer 2 vs Layer 3 interfaces)

  6. Who do dynamic circuits help? • High bandwidth transfers that need a guaranteed bandwidth rate • Terapaths • Low latency requirements • Video Conferencing • Virtual Worlds • “Intelligent” networking • Network links no longer static • Network can change with load requirements

  7. How do you use Internet2 dynamic circuit services? • Physical Connection • 1 or 10 Gigabit Ethernet Connection (DCS and HOPI) • OC192 SONET (DCS only) • Software • DRAGON • OSCARS (mid-term)

  8. DRAGON • NSF Funded project run by MAX and ISI East • Jerry Sobieski (MAX) • Tom Lehman (ISI East) • Allows for intradomain and interdomain circuit path calculation and setup • Currently deployed on HOPI • Deployed by the end of summer 2007 on DCS

  9. DRAGON – Key Components • Virtual Label Switched Router(VLSR) • Single PC connects to supported switch • Accepts RSVP packets and configures switch • Network Aware Resource Broker (NARB) • Performs inter/intradomain path calculation • Exchanges interdomain topology • Limited resource scheduling

  10. DRAGON – Key Components

  11. DRAGON User Software • User passes circuit parameters • Source, destination, bandwidth • Many optional fields such as VLAN tag • DRAGON Interfaces • CLI • ASTB (XML) • Web Page • Coming soon..OSCARS web service interface!

  12. DRAGON User Software – CLI • Command Line Interface (CLI) available • Peer-to-Peer Mode • Log-in to ingress VLSR and configure • User Network Interface(UNI) mode • Command line run on client • RSVP sent from client to ingress VLSR • RSVP message terminates at destination host

  13. DRAGON User Software - ASTB • Application Specific Topology Broker (ASTB) provides XML interface to DRAGON • Commit multiple LSPs at once to create AST

  14. DRAGON User Software – Web Interface • GUI frontend to the ASTB • Allows “point and click” creation of circuits • Google Maps API

  15. OSCARS Integration • Integrating OSCARS code with DRAGON to allow for interoperability with ESNet • Book-ahead reservations • Web Service Interface • AAA using X.509 certificates • Development release with limited topology exchange by end of summer, deployment mid-Fall 2007

  16. What do I need to get started? • Option 1: Install DRAGON (and OSCARS) • Assemble group of compatible switches or write drivers for your switches • Install VLSRs for each switch and a single NARB for your domain • Peer with Internet2 or RON software instance so can build interdomain circuits • Option 2: Build own application that interfaces to RON or Internet2 instance

  17. Conclusion • Internet2’s HOPI testbed and DCS network will provide dynamic circuits • Dynamic circuits provide exciting opportunities for researchers • Software developed and in development • Many at Internet2 willing to help you to deploy software
