Technical Summary This document describes the use of the Network Service Header (NSH) in a Service Function Chaining (SFC) enabled network with no payload data and carrying only metadata. This is achieved by defining a new NSH "Next Protocol" type value of "None". This new capability is proposed as a standard extension to NSH. Working Group Summary The extension is straightforward, and there was no difficulty in coming to consensus. Because of its simplicity, and since there was good acceptance of the draft, the WG chairs decides to proceed directly to WG last call without going through a WG adoption process. A fair number of people have reviewed the document and sent comments to the SFC mailing list, and the authors have addressed the comments that required addressing. There seems to be consensus in the working group that the document is ready for publication. Document Quality There are no known implementations. The document requests an IANA allocation that requires expert review. The SFC WG chairs are both listed as experts for this specific IANA registry, and have reviewed the draft. Personnel The document shepherd is Tal Mizrahi. The responsible Area Director is Alia Atlas.
