A node may make a local decision to put a "link to sleep" in coordination with the node on the other end. This is a 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. —Colby Thanks, John On Wednesday, September 9, 2026 at 06:58:41 AM PDT, Bonica, Ron <[email protected]> wrote: Folks, Many of the comments regarding draft-many-lsr-power-groups are resolved in this teas document.

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 Tony Li Vishnu Pavan Beeram Ron Bonica 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.
