Sounds reasonable, I am wondering whether it is sufficient for just defining
one new 'D' flag in the SVEC object? Why 'D' flag was not defined when RFC5440
was documented.
How do I know computed paths don't have any transit domains in common.
Domain diversity is more complicated when computed pat
Hi, Ramon,
Thank you for pointing the RFC6007 to me. I almost forgot this draft.
Yeah, you are right. This requirement can be satisfied by two approaches.
One is the 2-step approach which can be addressed by IRO/XRO, and the
other is the "D flag" in SVEC object in the H-PCE scenario according t
Hi, Qilei:
For domain diversity, when path computation traverses multiple domains
including one ingress domain, multiple transit domains, one egress domain,
there are several cases:
a. Computation path share none of these domains.
b. Computation path only shares both ingress domain

Very good points and clarifications. :-)
Regarding "are border nodes allowed", I think if inter-domain communication is
required, the border node should allow, shouldn't it?
Also I am wondering whether this requirement is only applied to H-PCE case?
H-PCE could be a typical use case. However I b
Hi, Qin:
I guess the sentences in section 1.3.2.2 of RFC6805 can answer you
question, I cite them here,
"
A pair of paths are domain-diverse if they do not transit any of the
same domains. A pair of paths that share a common ingress and egress
are domain-diverse if they only share the sam
Qilei:
I think (b) more makes sense. Maybe we further requires both egress node and
ingress node belong to multiple domains.
