Problems solved by technology

For service cards with an interface rate of 2.048Mbps, 155Mbps, 622Mbps, etc., if the data channels of the switch card and service card on the backplane still work at a rate of 10Gbps, it is obviously a waste of bandwidth and increases the power consumption of the whole machine ; In fact, it is enough for the data channel to work at a rate of 1Gbps

Embodiment Construction

[0034] In the traditional technology, no matter how high the interface rate of the service card on the backplane is, the data channels of the switch card and the service card on the backplane work at the maximum working rate. For some service cards with low interface rates, this method obviously The waste of bandwidth also increases the power consumption of the whole machine. In order to solve the above problems, the present invention proposes a system and a method for reducing the power consumption of the whole router.

[0035] see figure 1 , the system for reducing the power consumption of the whole router includes three parts: a board identification unit, a data processing unit, and a backplane rate control unit; wherein,

[0036] The board card identification unit is used to identify the board card in-position information and the board card type information, and submit the identified information data to the data processing unit;

[0037] The data processing unit is used t...

Abstract

The invention relates to the field of network communication equipment, and discloses a method for reducing the overall power consumption of a router. The working speeds of data channels of a switching card and a service card are regulated dynamically according to the interface rate of the service card, thereby reducing the overall power consumption. Key points of the technical scheme can be summarized in that: the type of a card on a backboard is identified, the interface rate of the service card is judged if the card is the service card, and the working speeds of the data channels of the switching card and the service card on the backboard are configured according to the interface rate of the service card, so that the overall power consumption of equipment is effectively reduced and the energy efficiency of the equipment is improved. In addition, the invention also discloses a system for reducing the overall power consumption of the router. The method and the system are particularly applied to high-end routers.

Description

technical field [0001] The invention relates to the field of network communication equipment, in particular to a system and method for reducing power consumption of a router. Background technique [0002] Generally, a router has multiple service cards and switch cards to form a data forwarding plane. The duty card provides an external interface, while the switch card is responsible for the data exchange between multiple service cards. The switch card and the service card are respectively connected to the backplane through the switch Provides a data channel between the service card slot and the switch card slot. [0003] The characteristic of the router is that there are many types of interfaces, and the speed of these interfaces ranges from 2.048Mbps to 10Gbps or even higher. In order to make the router adapt to the requirements of multiple interfaces, router manufacturers usually design the data channel rate of the switch card and service card on the backplane according t...
