  1. InterDomain Dynamic Circuit Network Demo Joint Techs - Hawaii Jan 2008 John Vollbrecht, Internet2 jrv@internet2.edu

  2. Interdomain Dynamic Circuit Network Global network that allows dynamic ckts to be created across multiple circuit networks Internet2, ESnet and Dante have worked in the DICE control plane working group Developed and continue to develop IDC protocol Interdomain dynamic circuit infrastructure is in place and being enhanced Additional Collaboration with Nortel and University of Amsterdam

  3. Agenda • SC07 presentation overview • Infrastructure at time of SC07 • Weather Map of DCN today • Quick overview of applications on weathermap • GOLEs in DCN • IDC architecture • Connecting a Campus User • DCN software suite • DCN status

  4. Global DCN Infrastructure at SC07 timeframe

  5. Physical Infrastructureat SC time

  6. Current Infrastructure of DCN http://packrat.internet2.edu/~zurawski/TIP2008

  7. LHC applications on DCN

  8. Phoebus and DCN • Phoebus breaks tcp connections into pieces to improve performance http://e2epi.internet2.edu/phoebus.html • Phoebus has the ability to create and use DCN a piece of the connection • Phoebus gateways are in place in Salt Lake and Syracuse NY now, being used • Other Phoebus gateway have been used in Ireland, Greece, and Poland, and more are being deployed in US now.

  9. DCN GOLEsExchange Points for Dynamic Circuits

  10. GOLE policy issues • Individual DCN GOLE is policy free • GOLE is non blocking • If both links agree path between them is made • This is initial demo being done at here and at JT • When GOLEs connect to each other • Link between GOLEs is limited resource • Now have to have policy that determines what is allowed on inter GOLE link • GOLE role :) may be • “superdomain” aggregating info on other domains • Part of GOLE domain that consists of only GOLES, administered by some standards body • GLIF role in defining DCN GOLE?

  11. IDC role in DCN • IDC is what allows DCNs in different domains communicate • IDC communicates with user and with other domains • IDC requests services from its Domain Controller • Different implementations from Internet2, Esnet, GEANT, Nortel

  12. IDC Architecture

  13. RONs and Campuses connecting to DCN

  14. DCN Software Suite • Suite combines DC and IDC software • DC - DRAGON • IDC - OSCARS • Suite is a “matched pair” of software • Version 0.1 released Jan 2, 2008 • Version 0.2 Jan 18, 2008 • Small changes and documentation update • Version 0.3 planned for April 2008 • Software suite matches what is running in Internet2 DCN and ESNet SDN

  15. Monitoring Dynamic Circuits • Monitor plane - both sides can monitor and deploy • Monitor links for infrastructure status and activity • Monitor ETE circuits for user status, traffic and debugging • Ongoing development and standards activity in this area • perfSONAR is our choice of tool - will be enhanced to add additional support • Dynamic circuits make naming and syntax standards imperative • Work with operations to define what is needed - especially between domains

  16. Operational State of DCN • Internet2 and ESNet are dynamic circuits are in “developmental” state • Good availability, ready to work with applications developing capabilities on network • Want to tune functions and policy to meet needs of real users • Support mainly from developers, starting to work with operations staff to transfer operational tasks to them - probably 6-12 months away • Support not 24/7, expect to respond to problems in 24 hours during work week. Often better. • Monitoring and debugging in development • Other DCN networks are in earlier stages

  17. Summary
