1. the system reducing overall power consumption of router, it is characterised in that including:

  • Board recognition unit, is used for identifying board information in place and identifying board type information, and the information data recognized is carriedGive data processing unit;

    Whether described identification board information in place refers to;

    identify and have board to insert respective grooves position on backboard;

    InstituteState and identify that board type information refers to;

    identify that the card inserting respective grooves position on backboard is switching card or service card, if businessCard, then be identified the interface rate of this service card;

    Data processing unit, judges also the interface rate of service card for the information data submitted to according to board recognition unitIssue the control command configuring switching card on backboard and service card data channel to backboard Rate control unit, request will the back of the bodyOn plate, the operating rate of the data channel of switching card and service card is configured to the speed suitable with the interface rate of this service card;

    The described information data submitted to according to board recognition unit carries out judgement to the interface rate of this service card and includes;

    If the minimum operating rate of the data channel of switching card and service card, then data on the interface rate≤

    backboard of this service cardProcessing unit issues control command to backboard Rate control unit, and request is by switching card on backboard and the work of the data channel of service cardIt is configured to minimum operating rate as speed;

    If the maximum functional speed of the data channel of switching card and service card, then data on the interface rate >

    =backboard of this service cardProcessing unit issues control command to backboard Rate control unit, and request is by switching card on backboard and the work of the data channel of service cardIt is configured to maximum functional speed as speed;

    If on backboard on the interface rate <

    backboard of minimum this service card of operating rate <

    of the data channel of switching card and service cardThe maximum functional speed of the data channel of switching card and service card, then data processing unit issues control to backboard Rate control unitOrder, the operating rate of switching card on backboard and the data channel of service card is configured to the interface rate more than this service card by requestAnd operating rate immediate with it;

    Backboard Rate control unit, for the control command that issues according to data processing unit to switching card on backboard and service cardData channel configures.
