Hi Robert,

 

yes, it is a typo. All nits are welcome! I will fix this in the next
version.

 

P.S. I plan to redundantly include the missing ICE prioritization formulas
in the next version.

What is 'co called' in this text:

o  In ICE, the conflict when two communicating end-points take the
      same controlling role is solved using random values (co called
      tie-breaker value).  In this protocol, the conflict is solved by
      the standard HIP base exchange procedure, where the host with the
      "larger" HIT switches to Responder role, thus changing also to
      controlled role.


Should it be 'so called'?

I will continue reading...

Hi, 

I read the latest version of the ICE specs. Based on this, I included more
details on ICE processing to the HIP NAT traversal draft. A quick summary of
the changes: 

* Introduced more details from ice-bis draft 
  * New terminology 
  * Aligned connectivity check procedure to match with ICE (3-way check is
now 4-way) 
  * Ta minimum value is now 5 ms (according to ICE bis) 
  * 4.9 Handoff: first update HIP relay to in order learn new server
reflexive locators 
  * New sections: 
     * 4.6.3.  Rules for Concluding Connectivity Checks 
     * 6.6.  Amplification attacks (new section) 
     * 6.7.  Attacks against Connectivity Checks and Candidate Gathering 
     * Appendix C.  Differences to ICE 
     * Appendix D.  Differences to Base Exchange and UPDATE procedures 
  * 7. IANA Considerations: added UNSAF considerations (references ICE) 
* updated references (some drafts are now RFCs) 

Feedback is welcome! For people already familiar with HIP, I'd recommend
reading "the diff to normal HIP" in section
https://tools.ietf.org/html/draft-ietf-hip-native-nat-traversal-14#appendix-

A New Internet-Draft is available from the on-line Internet-Drafts

This draft is a work item of the Host Identity Protocol of the IETF. 

        Title           : Native NAT Traversal Mode for the Host Identity
Protocol

Abstract: 
   This document specifies a new Network Address Translator (NAT) 
   traversal mode for the Host Identity Protocol (HIP).  The new mode is 
   based on the Interactive Connectivity Establishment (ICE) methodology 
   and UDP encapsulation of data and signaling traffic.  The main 
   difference from the previously specified modes is the use of HIP 
   messages for all NAT traversal procedures.
