  1. Generalized Label for Super-Channel Assignment on Flexible Griddraft-hussain-ccamp-super-channel-label-03IETF 83 - Paris, FranceMarch 25 - 31, 2012 Iftekhar Hussain (ihussain@infinera.com) Abinder Dhillon (adhillon@infinera.com) Zhong Pan (zpan@infinera.com) Marco Sosa (msosa@infinera.com) Bert Basch (bert.e.basch@verizon.com) Steve Liu (steve.liu@verizon.com) Andrew G.

  2. Agenda Changes since IETF-82 Open Issues Next Steps draft-hussain-ccamp-super-channel-label-03

  3. Changes • Ver-02 to Ver-03 • Modified • Changed the term “group” to “slot”in the n_start and n_end fields in the label • Added (similar to RFC4328) • a new G-PID type = OTUadapt • See (ITU-T SG15, Contribution C1573r1, Dec 2011 (Geneva)) • a new G-PID value to be assigned by IANA • A new Switching Type = Super-Channel-Switch-Capable(SCSC) • See draft-dhillon-ccamp-super-channel-ospfte-ext) • LSP Encoding Type = Lambda (as defined in RFC4328) draft-hussain-ccamp-super-channel-label-03

  4. Proposal - Summary • Extends [RFC3471] [RFC6205] • Defines a new generalized label format for super-channels assignment on flex-grid networks • Super-Channel Label extensions summary • Allows label assignment for both Contiguous Spectrum and Split-Spectrum Super-Channels • Provides two encoding options for the label • List/Range (n_start, n_end) • Bitmap draft-hussain-ccamp-super-channel-label-03

  5. Open issues • Terminology clarifications • Framework document submitted with definitions & use cases • WG agreement on Control Plane requirements • Alignment with ITU docs on data plane aspects draft-hussain-ccamp-super-channel-label-03

  6. Next Steps Requesting for review and comments Discuss merge options with other contributions draft-hussain-ccamp-super-channel-label-03

  7. Super-Channel Optical Parameters GMPLS Signaling Extensionsdraft-hussain-ccamp-super-channel-param-sig-00IETF 83 - Paris, FranceMarch 25 - 31, 2012 Iftekhar Hussain (ihussain@infinera.com) Vinayak Dangui (vdangui@infinera.com) Michael VanLeeuwen(MVanleeuwen@infinera.com) Marco Sosa (msosa@infinera.com)

  8. Agenda Motivation Extensions Summary TLV Summary Use Case Open Issues Next Steps draft-hussain-ccamp-super-channel-param-sig-00

  9. Motivation Coexistence of super-channels using different modulation formats Adjacent super-channels may affect each other detrimentally Desirable to evaluate the mutual impact of the existing and new super-channels on each other's quality of transmission draft-hussain-ccamp-super-channel-param-sig-00 9

  10. Extensions Summary • This draft defines GMPLS signaling extensions to convey following super-channel optical parameters: • Number of Carriers • Carrier Center Frequency (THz) • Carrier Modulation • Carrier Baudrate (Gbit/s) • Carrier FEC Type draft-hussain-ccamp-super-channel-param-sig-00 10

  11. TLVs Summary • Defines following new TLVs • Super-Channel Carriers TLV • Carrier sub-TLV Carrier • Carrier Center Frequency sub-sub-TLV • Carrier Modulation sub-sub-TLV • Carrier FEC sub-sub-TLV • Two options to carry these TLVs • Option 1 • RSVP FLOWSPEC or TSPEC Object • Option 2 (add in next revision) • With the Super-Channel Label draft-hussain-ccamp-super-channel-param-sig-00 11

  12. Super-Channel Carrier TL and Sub-TLVs draft-hussain-ccamp-super-channel-param-sig-00 12

  13. Carrier Center Frequency, Modulation, and FEC sub-sub-TLV draft-hussain-ccamp-super-channel-param-sig-00 13

  14. Use Case • Signal optical parameters of the super-channel in the RSVP message using proposed TLVs • Each node along the super-channel setup path allocates the required number of slices and learns the associated set of signaled parameters. • Each node advertises this information to other nodes in the network using routing extensions (see draft-hussain-ccamp-super-channel-param-ospfte) to apply added constraints draft-hussain-ccamp-super-channel-param-sig-00 14

  15. Open issues • Terminology clarifications • Framework document submitted with definitions & use cases • WG agreement on Control Plane requirements • Alignment with ITU docs on data plane aspects draft-hussain-ccamp-super-channel-param-sig-00

  16. Next Steps Requesting for review and comments Discuss merge options with other contributions draft-hussain-ccamp-super-channel-param-sig-00
