[Ballot discuss]

Are these reqs consistent with an additional RTT for key exchange?
If not, why is that ok? 100 setups/second implies a real need for a
0RTT model for any key exchange. That has significant protocol
design implications. I think you only need to note that, but that
noting that is really needed. (This could for example affect the
details of [1] or of later work similar to or built on [1]. Full

[Ballot comment]
Why isn't the WG working to solve the requirements in this document?

I ask because in general I think that requirement documents are good to motivate work and guide solutions, but their useful lifetime is not beyond that.  The solution is then what should be published.  I also ask because according to the March 2014 CCAMP Meeting Notes one of the authors said:  “we have possible solutions...but before coming with solutions we want an agreement on requirements", but I don't see any work that seems to be related, nor any other document referring to it.

Having said that, given that the document got all the way here, I won't stand in the way of publication.

The IESG has received a request from the Traffic Engineering Architecture
and Signaling WG (teas) to consider the following document:
- 'Requirements for Very Fast Setup of GMPLS LSPs'
  as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2015-09-30. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the

Establishment and control of Label Switch Paths (LSPs) have become
mainstream tools of commercial and government network providers. 
One of the elements of further evolving such networks is scaling their
performance in terms of LSP bandwidth and traffic loads, LSP intensity
(e.g., rate of LSP creation, deletion, and modification), LSP set up delay,
quality of service differentiation, and different levels of resilience.

The goal of this document is to present target scaling objectives and the
related protocol requirements for Generalized Multi-Protocol Label
Switching (GMPLS).

This document moved from the CCAMP WG to TEAS WG as part of the
routing WG changes. The progress of the draft through the WG
(first CCAMP, then TEAS) has been smooth.

The base GMPLS signaling and routing protocols have been implemented.
The requirements put forth in this document may be the basis for future
documents, some of which may be simply informational, while others may
describe specific GMPLS protocol extensions. While some of these
requirements may be have implications on implementations, the intent is
for the requirements to apply to GMPLS protocols and their standardized
mechanisms.

No.

No.

No specific concerns.

Yes, see thread –

Solid among those who are interested. "strong concurrence of a few
individuals, with others being silent" is a reasonable
characterization.

No discontent seen.

Yes.

No.

No.
