Hi Ron,

Some more comments. Some may have been asked before but I fail to understand them:

1) IPO is one of the tunneling technologies you propose must be supported. Do you mean that the ultimate solution should be able to trace SONET/SDH, DWDM, fiber forwarding trails?

2) Requirement 10,11: Do you mean it should ONLY support these kind of tunnels, or it should ALSO support these kind of tunnels? What about tunnels that don't use TTL? Should the solution support them or not?

3) Requirement 12, 13: Could you please explain more what do you mean by reverse MTU, and what is it useful for? 

4) section 7.4: Why MUST the solution be stateless? Will something break if it is not stateless? 

Thanks,
Shahram
