Subject: IP over SONET considered harmful?
I'd hoped that MPLS would solve this problem, but from reviewing
the drafts I believe that the LSRs _WILL_ decrement the TTL.
I think this is a non-issue, considering that with the next generation of
IP-only boxes ATM will become hopelessly useless.
Better yet, the real big boxes are removing any need to do clustering, so
the average number of IP hops for an NSP is going to be like 3 or 4.
