Hi Cleber, Sounds like you want "COTS product" instead of building one. If that is the case, take a look at ElasticTree: https://www.usenix.org/legacy/event/nsdi10/tech/full_papers/heller.pdf https://www.usenix.org/conference/nsdi10-0/elastictree-saving-energy-data-center-networks
You can also try to re-implement their idea. Regarding routes, controllers usually keep track of link state changes and give routes accordingly (take a look at how Floodlight keeps track of links using LLDP). Data collection could be done with sflow/netflow or openflow for bandwidth (if you use floodlight, you can use the REST API to get flow and port counters: http://www.openflowhub.org/display/floodlightcontroller/Floodlight+REST+API ). To measure power consumption, I believe that would be vendor specific (if they provide that functionality) or you need to have a smart/metered PDU that measures power per port. Hope that helps, -- Henrique Rodrigues http://www.dcc.ufmg.br/~hsr On Fri, Nov 15, 2013 at 10:34 AM, Cleber Araujo <clebersisi...@gmail.com>wrote: > Hello list! > > I am a beginner in the world of Mininet and openflow and I need some help > on advanced operation. > > As a goal, I want to make a network with energy efficiency.
