Bert,

The part that is new is that we want to automate the whole request and
routing process by using signaling protocols in the control plane. As
Kireeti pointed our earlier, current GMPLS protocols do not provide such
capability is the overlay model is used.

Regards,

Angela

Of course. But if a client wants to achieve path diversity at Layer 3, for
whatever reasons of reliability, then the service provider could provide
that client with the appropriate paths to use, based on that service
provider's physical network. Nothing new to invent?

And if the service provider sets up the separate paths over separate OSPF
areas, for example, one might ensure that the paths stay physically
separate.
