Dear All,
on behalf of authors of the RSVP-TE Signaling Extension for Links with Variable Discrete Bandwidth would like to ask for expert opinion. The Availability sub-TLV defined in the draft as a sub-TLV under Ethernet bandwidth profile. The length field in the Ethernet bandwidth profile will be different from the current definition(24), which might cause some backward issues.
Possible way to address this problem:
* define Availability as TLV that MUST be accompanied by Ethernet BW Profile TLV;
* define Extended Ethernet BW Profile TLV that includes Ethernet BW TLV and has variable length. Definition of Availability characteristics remains as sub-TLV which MAY be included into Extended Ethernet BW Profile TLV.
Regards,
Greg
