    S21, receive the control strategy that the SDN controllers of energy router are sent；
    S22, the packet header of the energy bag to be transmitted is parsed, obtain the energy bag to be transmitted transmission destination address and Control strategy requirement；
    S23, carried out according in flow table item of the control strategy of the parsing requirement in the functional module of the energy router Inquiry；
    S24, when inquiring the control strategy to match with the control strategy requirement in the flow table item, treated according to described The destination address of transmission energy bag transmission obtains output port of the energy bag to be transmitted in the energy router；
    S25, according to the output port and the control strategy, the energy bag to be transmitted is transmitted.
  10. 10. according to the method for claim 9, it is characterised in that the step S24 also includes：
    When not inquiring the control strategy to match with the control strategy requirement in the flow table item, by the control Policy mandates are sent to the SDN controllers, so that the SDN controllers require generation control plan according to the control strategy Slightly.
