Internet2 Dynamic Circuit Services and Tools

This presentation covers the essentials of Internet2's dynamic circuit services, including an overview of the Internet2 Network, the concept of dynamic circuits, their benefits, and who they assist. It provides details on connecting to the network, necessary software, and getting started with dynamic circuit technology. The session discusses the DRAGON and OSCARS software systems for managing dynamic circuits and explains how these tools help create network resources flexibly and efficiently. With practical insights, attendees will learn to leverage dynamic circuits for improved bandwidth and low-latency networks.

Presentation Transcript

  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
