Hello,
I am with Daniel and JP regarding the need to start considering
multiple domains and serious scalability pitfalls that might occur.
Just a comment regarding setting numbers: although 20 domains would be
a good start for testing some of the different ID?s and proposals, I
think it would be best to keep in mind that any solution should scale
to other numbers >20. If a proposal is not scalable, at least provide
the mechanism to deal with the situation: for example by detecting the
problem (monitoring flooding, waiting times etc) and reporting back
with notification error etc.). To this end I propose adding a
Scalability Section to all the upcoming IDs.
Regards,
Meral

Hi PCE members.
As you may (SHOULD ;-) ) have noticed in our agenda for Hiroshima,
Daniel King will present his I-D named "The Application of the PCE
Architecture to the Determination of a Sequence of Domains in MPLS &
GMPLS" (introduced during the Stockholm meeting). Nonetheless our
current charter soberly says:
"The PCE WG will work on application of this model within a single Domain
or within a small group of domains (where a domain is a layer, IGP area
or Autonomous System with limited visibility from the head-end LSR). At
this time, applying this model to large groups of domains such as the
Internet is not thought to be possible, and the PCE WG will not spend
energy on that topic."
In other words, we are flirting with our charter border and the scope
of some drafts depends on it. In this context, the chairs would like
to get a feedback from the WG on evolving towards larger groups of
domains.
Does the WG think we are now ready to follow this path? Do you have
operational requirements and/or concerns in mind in terms of
applicability, order of magnitude, implementation...? Comments are
very welcome.
You are probably aware that we have passed over a milestone about
rechartering: beyond the upcoming meeting, your feedback will be
useful input for the envisioned charter update (targetted for the end
of the year).
Many thanks
JP & Julien
