Dear Watson,


Thank you for your review. Concerning the security considerations, this method does not introduce new security problems, basically because it does not create any new field or option into packets. Eventually, we can imagine some man in the middle, changing some bits into the packet, but this kind of behavior does not affect the network. I think it can affect one measurement for a particular hop where he/she is intercepting, but this case is similar to any traffic; therefore, I do not see any potential problem. 
Are you visualized another security problem? 


Regards,

	J. Igancio
