  2. Updates from the last version • Editorials • 4.2.2. Wavelength Restriction Field sub-TLV • Align with [Gen-Encode]. • 4.3. Signal processing capability restrictions • Refine the definition of <endpoint-restriction> to align with [WSON-Encode] as follows: <endpoint-restrictions> ::= <LABEL-REQUEST> <label-restriction-list> [<signal-compatibility-restriction>...] where signal-compatibility-restriction ::= <MODULATION-FORMAT-LIST>|<FEC-LIST>

  3. Updates from the last version • 4.3.5. Objective Functions (Add a New Section) The Following new objective functions are defined (Objective Function Codes: TBA) . • Maximum residual spectrum Description: Find a Path such that ( Max { (s(Li))), i=1...N}) is minimized. • Minimize the free spectrum Description: Find a Path such that ( Max { (S(Li)), i=1...N}) is maximized. • Maximize the remaining total spectrum. Description: Find a Path such that ( Max { (ST(Li)), i=1...N}) is maximized. Issue: Shall this section be a part of the current draft or be a separate draft?

  4. Next Steps • Adopt to be a WG document  • Refine and resolve open issues in the revision
