  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

  9. QUESTIONS ? THANK YOU
