  1. OSPF-TE Extensions for Flex-griddraft-dhillon-ccamp-super-channel-ospfte-ext-06IETF-88, Vancouver Rajan Rao, Abinder Dhillon, Iftekhar Hussain, Marco Sosa, Biao Lu

  2. Agenda • Changes since IETF-83 • Proposal summary • Next Steps

  3. Changes in V.06 • Ver.06 submitted in Oct’13 • No significant change since IETF-83 (Paris) • Mainly refresh & editorial cleanups

  4. Proposal - recap • Meets requirements captured in FWK doc • Simple extensions to ISCD [RFC 4202] • New Switching Capability • Flex-Grid extensions in SCSI • Flex-Grid extensions summary • Divide C-band in to ‘Slices’ of certain width • Advertise ‘Slice’ availability • Support for BW advertisement per priority • Support for Min & Max ‘Frequency Slot’ use per LSP draft-dhillon-ccamp-super-channel-ospfte-ext-06.txt

  5. Next Steps • Time to discuss solution drafts? • Merge options with other contributions • Review comments are welcome

  7. Agenda • Changes since IETF-87 • Proposal - Summary • Next Steps draft-hussain-ccamp-super-channel-label-06

  8. Changes in V.06 • Ver.06 submitted in Oct’13 • No significant change since IETF-83 (Paris) • Mainly refresh & editorial cleanups

  9. Proposal - Summary • Meets requirements captured in FWK doc for single frequency slot case • 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 three encoding options for the label • List of (n, m) • List/Range (n_start, n_end) • Bitmap draft-hussain-ccamp-super-channel-label-06

  10. Next Steps • Status: some offline discussions happened in the past • Pending issues – encoding specifics • Merge options with other contributions • Review comments are welcome

Super-Channel Optical Parameters GMPLS Routing Extensionsdraft-hussain-ccamp-super-channel-param-ospfte-03.txtIftekhar Hussain (ihussain@infinera.com)Marco Sosa (msosa@infinera.com)Abinder Dhillon(abinder.dhillon@us.fujitsu.com) Super-Channel Optical Parameters GMPLS Signaling Extensionsdraft-hussain-ccamp-super-channel-param-sig-03 Iftekhar Hussain (ihussain@infinera.com) Vinayak Dangui (vdangui@infinera.com) Michael VanLeeuwen(MVanleeuwen@infinera.com) Marco Sosa (msosa@infinera.com) IETF-88, Vancouver

  12. Motivation • Coexistence of super-channels using different modulation formats • Adjacent super-channels may affect each other detrimentally • It is desirable to evaluate the mutual impact of the existing and new super-channels on each other's quality of transmission

  13. Proposal Summary • This draft defines GMPLS routing/signaling extensions • Number of Carriers • Carrier Center Frequency (THz) • Carrier Modulation • Carrier Baudrate (Gbit/s) • Carrier FEC Type

  14. Next Steps • Framework requirement discussion? • Review comments are welcome
