3. Agenda Changes in version -04 OTN specific extensions and encoding of the Bandwidth Accounting sub-tlv Technology Specific Flags Bandwidth Units Improvements Bandwidth Efficiency Next steps

4. OTN specific encoding for the BA sub-tlv Technology Specific Flags: G – Type of Tributary Slot (2,5 or 1,25 Gbps) T – Terminating Capability S – Switching Capability R – e.g. ODU flex resizable (Flag or Signal Type) …

5. OTN specific encoding for the BA sub-tlv Bandwidth Unreserved Bandwidth for fixed Service Types: Number of Service Types Unreserved Bandwidth for variable Service Types: Bytes/sec in IEEE floating point Max LSP Bandwidth: Bytes/sec in IEEE floating point

6. Improvements – Bandwidth Efficiency 1/2 Priority

7. Improvements – Bandwidth Efficiency 2/2 Unreserved Bandwidth for fixed containers

8. Next steps Collect feedbacks from the meeting Collect feedback on the ML Keep alignment with OTN Framework and G.709 Info Model. Keep alignment with bccgd draft
