A couple of quick questions...
Section 3.3 says
As RFC 3473 does not support call and connection separation
or soft permanent connection
But surely RFC 3473 does support soft permanent connections? There are several techniques,
but perhaps the most popular is explicit label control. In view of this, you need to
describe how you map between the two techniques when transiting between 3473 and 3474
network types. (Not just how you carry one technique across the other type of network, but
how you handle the case where the end points are in different types of network.)
Section 3.3 also says
c) support for extended restart capabilities
(c) is a local procedure and has no interworking implications
Are you sure that the Hello interactions and state recovery between 3473 and 3474 LSRs has
no interworking implications?
Section 5.4 says
Other objects may be received at the 3474/3473 interface,
esp. the Call_ID and Call_OPS objects defined in RFC 3474.
These are passed transparently across the 3473 domain.
This may be true, but you need to cover the case where the 3473 domain generates an error
(such as PathErr). Presumably the mandatory Call_IS and Call_OPS are added back in to the
message when it reaches the 3474 domain?
