  2. Outline • Overview • Changes from 02 to 03 • Next Steps

  3. Overview • This draft covers routing extensions forMLN/MRN (RFC 5212) based on OTN • Extends IACD (RFC 6001) to include OTN layer identification • Covers following interworking scenarios • OTN & Ethernet • OTN & FlexGrid • OTN & SONET/SDH • OTN & OTN

  4. Changes from 02 to 03 • Minor cleanups • Section rearrangements • Contains interworking examples

  5. Next Steps • Would like to move the draft forward

  6. Backup

  7. Example Advertises ISCD_PSC, IACD1 10GigE 100GigE Hybrid Node Ethernet Switch 300G Advertises ISCD_PSC, IACD2 OTU4 OTU4 OTN Switch Advertises ISCD_OTN, IACD1 IACD2 Advertises ISCD_OTN, IACD1 IACD2 IACD1 Upper SwitchCap/EncTyp : PSC/Ethernet Lower SwitchCap/EncType : OTN-TDM/G.709 ODUk SCSI : SignalType+HierarchyODU2-ODU4 (For 10GigE) IACD2 Upper SwitchCap/EncTyp : PSC/Ethernet Lower SwitchCap/EncType : OTN-TDM/G.709 ODUk SCSI : SignalType+HierarchyODU4(For 100GigE)

  8. Changes from 01 to 02 • Layer ID TLV is modified to carry additional information to infer, if the Layer Identification belongs to upper region or lower region R bit is used to make sense whether the Layer ID is for Lower region or upper region. 1 means upper region and 0 means lower.
