Hi John and all,

I submitted the following updated drafts concerning
 "Mobility Functions in the NTLP/QoS-NSLP":
 
 - draft-jeong-nsis-mobility-ntlp-01.txt
 - draft-lee-nsis-mobility-nslp-01.txt

These drafts discussed the following issues in each layer:

1. Interactions with the NTLP and the NSLP in mobility support
   A. What should the NTLP do for the NSLP NOT to trigger an error message 
       indicating ‘Can-Not-Be-Forwarded-to-the-LAST_NODE (e.g., MN)’ after handover?
   B. What should the NTLP do for the NSLP to immediately re-establish its states 
       after handover?
   C. What should the NTLP do for the NSLP to teardown the old states 
       on the obsolete path after handover?

2. Crossover Node Discovery
   A. If the merging point of the old and new paths can not perform NSIS functionality, 
       how does the NTLP find the NSIS-aware crossover Node 
       on the jointed/common path?
   B. How does the NTLP of a Candidate Access Router (AR) find the candidate    
       Crossover Node to fast re-establish the existing NSLP state during handover?

3.  Dead Peer Discovery
   A. If the crossover node fails, how does the NTLP detect failure of the Crossover Node 
       and find an appropriate new Crossover Node?
 
4. Interworking with Mobility protocols
  A. How does the NTLP in the current AR interact with CARD
      to fast re-establish its associated NSLP states?
  B. How does the NTLP in Current AR interact with CT 
      to send its associated existing NSLP states to the candidate AR?

5. State Management
  A. How (and when) can the QoS-NSLP adjust the refresh timer value according
     to network environment?
  B. Is it necessary to set the refresh timer value in a wireless network to a smaller 
      value than that in the core (wired) network?

6. QoS-NSLP state Re-establishment
  A. How does the QoS-NSLP interact with the NTLP to fast re-establish the QoS-NSLP 
      states after handover?
  B. How can the delayed signaling problem be solved in a receiver-initiated approach?

 Please, comment in our drafts,

Thanks and Regards,
