Re: [v6ops] New Version Notification for draft-xiao-v6ops-nd-deployment-guidelines-02.txt

Hi, Xipeng,
I 'd like to make a personal comment on the term "deployment".  Usually, this term refers to the deployment and application of a device or system for network operators or enterprise customers who operate their own network. Specific protocols such as ND are part of the device or system. Whether or how the device supports ND should be decided prior to the phase of operator deployment.  So is it replaced by other terms? What's your opinion?

Best regards
Chongfeng

Dear folks,
 
We submitted a major revision of ND-deployment-guidelines draft.  We believe its quality is significantly improved.  The key points are below.  Your review and comments will be greatly appreciated.    XiPeng & the co-authors
 
Problem statement: 
•         Various issues and solutions are documented in more than 30 RFCs. It is difficult to keep track of all these issues and solutions, and how the various solutions fit together.   These include: ND Proxy, Optimistic ND, ND for mobile broadband, ND for fixed broadband, ND Mediation, Operational ND Problems, Wireless ND (WiND), DAD Proxy, SAVI/RA-Guard/RA-Guard+, Enhanced DAD, Scalable ARP, Reducing Router Advertisements, Unique Prefix Per Host, GRAND, Proxy ARP/ND for EVPN etc.
 
This draft:
•         Summarizes the known ND issues and optimization solutions into a one-stop reference. 
•         Present an insight: isolating hosts is effective in solving ND issues. 
•         Propose 4 isolation methods and discuss their applicability: P2P link & subnet isolation, P2MP link & subnet isolation, GUA isolation, proxy isolation 
•         Describe guidelines for selecting a suitable isolation method based on the deployment scenario.
 
Regards,

Abstract:
   Neighbor Discovery (ND) is the key protocol of IPv6 first-hop. ND
   uses multicast extensively and trusts all hosts. In some scenarios
   like wireless networks, multicast can be inefficient. In other
   scenarios like public access networks, hosts may not be trustable.
   Consequently, ND issues may happen in various scenarios. The issues
   and solutions are documented in more than 30 RFCs. It is difficult
   to keep track of all these issues and solutions, and how the various
   solutions fit together. Therefore, deployment guidelines are needed.
 
   This document firstly summarizes the known ND issues and
   optimization solutions into a one-stop reference. Analyzing these
   solutions reveals an insight: isolating hosts is effective in
   solving ND issues. Four isolation methods are proposed and their
   applicability is discussed. Guidelines are then described for
  selecting a suitable isolation method based on the deployment
   scenario.
