Re: Regarding draft-li-6man-service-aware-ipv6-network-00

Hi Zhenbin,

Thanks for your draft. I have a few general questions:

1. As you may know, it's been impossible to deploy new IPv4 options for operational reasons, and also very difficult to deploy new IPv6 extension headers or options. So my first question about your proposal is: what is the intended scope? Do you expect such options to be deployed locally or over the open Internet? (For some background on this question, see https://tools.ietf.org/html/draft-carpenter-limited-domains)

2. How does this proposal relate to the existing standard for network service headers (https://tools.ietf.org/html/rfc8300)?

3. How does ths proposal relate to the existing standard for segment routing (https://tools.ietf.org/html/rfc8402) and the segment routing header (https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header)?

4. How does this proposal relate to FAST tickets (https://tools.ietf.org/html/draft-herbert-fast-03)?

   Brian Carpenter
