The MPLS WG Archive

Yakov....I can understand why you hold this view but I have to disagree.

What about static LSPs?  And in theory one can set up LSPs using any
signalling protocol you like....say PNNI....and in theory one does not need
an IGP (IGPs don't dist labels).  If you also take your analogy further to
GMPLS, then perhaps we should observe that SDH/Sonet never really existed
until they were blessed with the IP-based control-elements?  But we know
that is not true.

MPLS does create layer networks in the user-plane, GMPLS does not....these
existed before.  

my regards, Neil
