Interdomain Dynamic Circuits

This document explores the integration of interdomain dynamic circuits within advanced networking infrastructures such as Internet2, ESnet, and GEANT2. Focusing on the practical demonstration of dynamic circuit capabilities, it covers experimental developments at the University of Amsterdam and highlights how token-based operations streamline circuit setup sequences. Aspects such as monitoring dynamic circuits, utilizing perfSONAR for performance management, and ongoing collaborative protocol developments with groups like IETF and OGF are discussed. The future of dynamic circuit management, including authorization and scheduling, is also addressed.

Presentation Transcript

  1. Interdomain Dynamic Circuits WeatherMap -- http://packrat.internet2.edu/~zurawski/SC2007/DCN/UNL.html

  2. Physical Infrastructureat SC time

  3. Internet2 DCN and Esnet SDN Interoperation

  4. GEANT2/AutoBAHN Interoperation with Internet2 and ESnet

  5. Phoebus over Dynamic Circuits Phoebus “network” Phoebus infrastructure on DCS

  6. University of Amsterdam connection for experimental development CineGrid content sent from Amsterdam to SC Experimental demo show use of token between reservation and ckt setup sequences

  7. Nortel Interaction with Interdomain Dynamic Circuits Nortel implements IDC protocol as a “wrapper” over its DRAC controller Uses IDC to setup ckts between Ottawa and showfloor to send Video And between Nortel and Internet2 booths to do Grid File Transfer

  8. SCO7 Dynamic Circuit infrastructure

  9. Monitoring Dynamic Circuits • Monitor plane - both sides can monitor and deploy • Monitor links for infrastructure status and activity • Monitor ETE Ckts 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 ckts make naming and syntax stds imperative

  10. Future Development • DICE IDC Protocol development will continue, perhaps with expanded group • Will collaborate with groups developing protocols being developed in other standards groups • IETF, IEEE, OIF, ITU, OGF and others • GLIF control plane development • Some major areas of future development • Monitoring interdomain dynamic ckts • Managing interdomain reservations and guarantees • Sharing authorization between reservation and scheduling step and ckt setup step • Dynamic scheduling of ckts using different technologies • Topology description and sharing between domains • AAA between domains • GRID model vs Network model infractures

  11. Making a connection from Showfloor

  12. The End Questions?

  13. Steps to adding a regional • Connect a host to I2 DCN using static connection thru a switch request dynamic connection across I2 from I2 IDC • When second host want to connect thru same switch and share ckt bw from DCN to switch implement dynamic control on the regional switch using “dynamic control suite” request dynamic connection from regional IDC • use Lookup service to map host name to L2 link-id Moving from step 1 to step 2 change Lookup Service to use regional link-id associated instead of I2 DCN link-id - user changes nothing
