Abstract:

   Many networks have a daily utilization pattern.  For example, a
   network might be busy during the day and less busy at night.

   If the network is robust, it has enough capacity to satisfy demand
   during peak hours and excess capacity during non-peak hours.  That
   excess capacity increases energy costs and environmental impact.

   [I-D.many-teas-power-steering] introduces a Power Conserving Path
   Placement Strategy (PCPPS).  When possible, PCPPS concentrates
   traffic onto a small set of network resources.  When traffic is
   concentrated onto a small set of network resources, other network
   resources become idle and can be powered down until they are needed
   again.  This solves the problem of excess capacity during non-peak
   hours.

   PCPPS uses information that is distributed by an IGP.  This document
   specifies the IS-IS encoding for that information.
