Re: [spring] WG Adoption Call for draft-dong-spring-sr-for-enhanced-vpn

All,

Before I make a decision on expressing my support or indicate no support I
would like to better understand what resource reservation is being
discussed here.

draft-ietf-spring-resource-aware-segments-01 also talks about
"reservations" yet lacks clarity what those reservations will actually be.
It provides analogy to MPLS-TE, but at least those who build MPLS-TE
products are aware MPLS-TE or even MPLS GB-TE does not provide any data
plane reservations. All both do is to provide control plane resource
bookings.

So fundamentally does draft-ietf-spring-resource-aware-segments-01 and this
draft in question also are trying to now map SIDs to control plane
resource bookings ? Note fundamentally in all above cases it only works
when all traffic in yr network is actually using such reservations as
otherwise unaccounted traffic will destroy the game completely for those
who think we see green light we are good to go. That is also why for real
TE it is/was critical in MPLS-TE to provide such engineering for all of
your ingress-egress macro flows.

Even then if you start to run other traffic on the same links ... say
multicast or control plane storms of any sort - again all of your assumed
reservations are immediately becoming unnecessary complexity with zero
benefits.

So with that let's make sure we understand what is being proposed here.

Btw if someone has a pointer to discussion about
spring-resource-aware-segments it would be great too. My few years of email
history does not return much. Maybe the draft got renamed during publishing
as SPRING WG item.

Thx,
R.
