Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present invention dynamically changes the connection mode of the network according to the real-time monitored network data flow, transmission speed or file size, so as to realize the optimal dynamic matching of the network bandwidth and the power consumption of the network card, thereby reducing the power consumption of the network card. The solution is: when the network is lightly loaded (low speed, small file transfer, web browsing, etc.), connect at a low speed mode, such as 10Mbps, with the main purpose of saving power; when the network is heavily loaded (high speed, large file transfer), connect to In the high-speed mode, the main purpose is to increase the network bandwidth. At the same time, due to the increase of th...

Abstract

The invention provides a dynamic control method of a network card consumption and connection mode which belongs to the power saving technique, and a device thereof. The method includes: monitoring data transmitting state of network in real-time, obtaining statistic value of data transmitting state in existing or scheduled time period; obtaining an object connecting mode matched with existing data transmitting, switching the network connecting mode into the object connecting mode. In an embodiment, network connection is not forced in certain connection mode, realizes dynamic changing connecting mode according with load assignment by monitoring data transmitting state of network and comparing with switch condition, can process dynamic switch among various mode, increases utilization rate of transmitting band width and realizes optimizing dynamic match of band width / energy consumption.

Description

technical field [0001] The invention relates to the power saving technology of the network card, in particular to a dynamic control method and device for the power consumption and connection mode of the network card. Background technique [0002] In the application of mobile devices such as notebook computers, system power consumption and battery life are one of the core indicators of mobile devices. In the power consumption of the system, the power consumption of the network card accounts for a large proportion. For example, in a notebook with 12W in idle state, the power consumption of the gigabit network card is about 1W, accounting for about 10% of the total power consumption of the notebook. Therefore, in order to reduce power consumption, network card manufacturers have provided many power-saving modes, such as No Link (no connection mode) and deep sleep mode. Most of these modes are for scenarios where no network cable is inserted or no network function is required. ...
