[size trimmed] OK, so you want to avoid nodes which draw more power. Are you assuming that minimizing the traffic across a node also minimizes the power that node draws?
If yes: - please provide concrete examples of how this actually works. In my experience the power draw by a router or switch is pretty constant, more driven by the *existence* of links (because links -> linecards -> power draw) than by the *traffic* on those links. If not, what do you hope to accomplish by avoiding higher-power nodes? eric > -----Original Message----- > From: Balaji venkat Venkataswami [mailto:[email protected]] > Sent: Thursday, February 07, 2013 10:59 AM > To: Eric Osborne (eosborne) > Cc: Shankar Raman; [email protected]; [email protected] > Subject: Re: Power aware networks : Comments requested from routing > community > > Dear Eric, > > We seem to be discussing at cross purposes. > > The root of our position is not what you have stated.
