Hi, Juwei:

 

I am adding the comments related to MANET peers. 

 

Please see inline [RRR].

I?ll explain the motivation of the hierarchical P2P-SIP architecture. 

 

The precondition of applying the hierarchical approach is that the
SIP-over-P2P structure is adopted. We have presented the benefits of that
two layer approach in our draft. 

 

Various P2P overlays have already existed such as Chord, Pastry and etc. We
can?t roughly tie up a specific P2P overlay as the peer locating service for
SIP but exclude other overlays. Only one overlay is inflexible and can?t
satisfy requirements of all the peers. For example, the requirement of a
mobile peer in MANET differs from that of a powerful host in Internet. 

 

[RRR] True, if it is pure MANET networking with no interfacing by nay MANET
nodes with any fixed infrastructures.

 

[RRR] If one or some MANET nodes have the ability to communicate with some
fixed infrastructures somewhere in the network(s), the requirements might
not be so hard to meet.

 

Thus we believe that heterogeneous P2P overlays will exist, and when we use
them as the underlying peer locating service for SIP we can only
inter-connect them to retain the connectivity feature of SIP. 

 

Comments are welcomed!

 

 

Thanks

WHEN YOU CAN MANIPULATE NODES OF MULTIPLE OVERLAYS, WHY NOT MANIPULATE THEM
TO USE ONLY ONE OVERLAY? 

THANK YOU.

Yes, I agree with Seaward, hierarchically inter-connecting heterogeneous
overlays is more practical than the mesh based approach.  

 

 

 


Interworking among heterogeneous hierarchical is more efficient than do it
meshy, you can not expect a flat huge mesh over whole world can work
reliably, the reason why mesh is used is the absence of a acceptable
standard.


Thanks.

WHEN NUMEROUS MULTI-OVERLAID NODES ARE INTERCONNECTED, "the interworking
among heterogenous overlays" IS GENERALLY MESSY NOT HIERACHICAL. 

THANK YOU.

The NAT issues will be discussed in our future drafts. 

This draft focuses on the interworking among heterogenous overlays and the
SIP-over-P2P architecture in one single overlay is proposed by E. Shim etc.

THE DOCUMENT IS GORGEOUS BUT NEED RENAME AS "A MESHY ARCHITECTURE AMONG
MULTIPLE P2P-SIP NETWORKS".

FOMULA "Node-ID=Hash(Node-IP)" HAS PROBLEM WITH MULTIPLE NODES BEHIND A NAT.


  


  
 


  


  
 THERE IS LITTLE ABOUT P2P OR SIP, FOR ONE SINGLE OVERLAY.
