Dear Authors,

We noticed that in the section 3.5 of your draft, the Ping-pong type of handover is listed as one of the issue to be solved. Therefore, we would like to bring to your attention that an ID we submitted recently also covers the same topic (draft-cheng-mobility-issues-01.txt). And that ID discussed some of the possible solutions. If possible, we would like to hear your comments on the draft. 

Since our draft is still not yet placed on the IETF server, please find a copy at:  http://www.psl.com.sg/draft-cheng-mobility-issues-01.txt

Thanks and regards

Cheng Hong

The goals of this draft are to analyze the effects of mobility in NTLP/NSLP 
and give some guidelines about how to tackle  various issues caused by 
mobility (as well as generic route change) in the Internet signaling protocols.  

This draft discussed the following issues in NTLP/NSLP layers:

   - analysis of various mobility scenarios in NSIS signaling and statement
     problems
   - Crossover node discovery and Path update caused by mobility and 
     route change
   - Dead peer discovery
   - Case examples of NSIS signaling according to handover cases
   - Interaction with mobility signalings (e.g., HMIPv6, FMIPv6, CARD, and CTP)
   - Uni- and bi-directional state establishment, State Management, and
     State establishment in network mobility as additional issues
   - Security considerations in various scenarios such as MN as sender/receiver,     
     multihoming scenarios, using context transfer, proxy scenario, and AAA.

There are also some issues which need to be discussed in the next version 

   - Multihoming related issues
   - Both End-Hosts are Mobile 
   - Split of NSIS functionality
   - Open questions in each section

 All comments are welcome

Regards,

Sung-Hyuck
