Hi Umut,
 
I'm interested that you write
   No issues are expected regarding backwards compatability as the
   sequence of the header remains unchanged.
 
Suppose that an old format packet reaches a new format router.
Suppose that the TTL on the old format packet is set to 192.
Won't the new format router decide that the TTL is zero?
 
Suppose that an old format packet has TTL of 193. Won't the new format router decide the S bit is set?
 
I suspect the first thing you need to do is not determine what the largest diameter of an MPLS network is, but what implementations in the field do with the field when initiating packets. For example, are their special cases where TTL is set to 255?
 
Cheers,
Adrian

Dear Members,

Hereby I would like you to take a look at my recently/newly posted draft:
https://tools.ietf.org/html/draft-keten-mpls-expbit-00

I sincerely belief that this fundamental change is required. Feedback/Interest/Advise is appreciated.

Kind Regards,
