Hi,
I'm not sure you answered my questions.
Thanks,

Ron,
I'm sure I missed it so I apologize in advance, but how do you deal with a link
which should be powered off but which can't be due to the presence on LSPs
which should be re-routed, or a link which appears to be ready to power off but
which shouldn't be because the LSPs on it are crucial and which can't be
rerouted?
<cb> If a link is both power-save-capable and there are currently no LSPs
traversing it, then it is a candidate to be put to power-sleep. A node may
make a local decision toput a "link to sleep" in coordination with the node on
the other end. This isa function of the sleep management component that Ron
has described and is beyond the scope of this document.
Or, how do you power on a link in anticipation of a huge traffic surge which
should be non-disruptively handled?
<cb> Waking up a link can be triggered by an ingress node if it fails to find a
path for a new bandwidth request.

Folks,
Many of the comments regarding draft-many-lsr-power-groups are resolved in this
teas document. So, I am informing LSR and TEAS that this new version has been
posted.

Internet-Draft draft-many-teas-power-steering-02.txt is now available. It is a
work item of the Traffic Engineering Architecture and Signaling (TEAS) WG of
the IETF.
Title: A Power Conserving Path Placement Strategy (PCPPS)
Authors: Colby Barth

Name: draft-many-teas-power-steering-02.txt
Pages: 13
Dates: 2026-09-09
Abstract:
This document introduces a Power Conserving Path Placement Strategy
(PCPPS). During periods of low demand, PCPPS concentrates traffic
onto a small set of network resources. This causes other network
resources to become idle or nearly idle. When demand increases,
PCPPS redistributes traffic as required.
