While this is a reasonably well-written draft, I don't see that it adds
anything to what we already have in the core RFCs.
In section 4.3 you have...
There are two options
for PCE to send pre-configured route as follows:
PCRep is used to respond route computation result naturally. If it
is used to send pre-configured route, a new flag SHOULD be defined to
indicate the route carried is pre-configured route.
Two questions:
1. What is the other option? You only list one option.
2. Why do you need a flag to indicate that a route is pre-
configured? Why does the PCC care how the route was
derived?
You slighlty answer question 2, in section 5.1 where you say...
When PCC requests pre-configured route
...but why would the PCC ask for a pre-configured route? It just wants a
route. If there is a policy to be applied by the PCE in selection of the
route, this should be indicated using the normal policy functions. If there
is an objective function/algorithm to be applied in selecting the route,
this should be indicated using the OF object.
So I think that you don't need the pre-configured route flag.
Cheers,
Adrian
