Hi Jouni,
You're right that the current draft text doesn't provide any information about the discussion. So how about add the following text at the end of section 3.1: This document only defines the Availability TLV, how the existing Switching Capability makes use of the Availability TLV will be addressed in a different document. An example is to define a new type code for the Availability TLV, if the Switching Capability-specific information (SCSI) supports TLV format. Section 3 of RFC7688 provides clear definition for new SC and SCSI. But since the conclusion is to use another different document, other than this document to explain the technology specific usage(including the SC/SCSI allocation), it’s preferred not to include the such text in this document.

Ok, thanks for sharing this. This document had no mention or guidance of this kind of decision. I would have assumed some text since the extension defined in this document is seemingly backwards incompatible without some glue. As the text is now, is not sufficient. I would appreciate text along lines that can be found in Section 3 of RFC7688 with an addition of the details you point out below regarding the allocation of new Switching-capability types. Also, it would not hurt describing (with the Switching-capability types text) how the situation where an existing non-TLV Switching Capability-specific information and the new TLV-based information have to coexist.. or whether that kind format is not supported. - Jouni > For example, for the SCSI which supports TLV(e.g., OTN/WSON), a new type code > is needed to make use of availability TLV. > For the SCSI who doesn’t support TLV(e.g., PSC), a new SC types is needed. > > BR, > Amy > > -----Original Message----- > From: jouni.nospam [mailto:jouni.nos...@gmail.com] > Sent: Monday, October 17, 2016 5:50 AM > To: gen-art@ietf.org<mailto:gen-art@ietf.org> > Cc: > draft-ietf-ccamp-ospf-availability-extension....@ietf.org<mailto:draft-ietf-ccamp-ospf-availability-extension....@ietf.org> > Subject: Gen-ATR review of > draft-ietf-ccamp-ospf-availability-extension-07 > > I am the assigned Gen-ART reviewer for this draft.
