Digital communication device capable of saving electricity, and electricity-saving control device and method thereof

Abstract

The invention discloses a digital communication device capable of saving electricity, and an electricity-saving control device and a method thereof. In the digital communication device, a plurality of interface modules aiming at different interfaces are divided; when interfaces corresponding to interface modules are configured as downlink interfaces and last for a Down state, the interface modules can be controlled to enter into an electricity-saving state, thereby realizing a 'non-full-matching access' electricity-saving effect of the digital communication device; after all the downlink interfaces of the digital communication device last for the Down state, the interface modules with corresponding interfaces configured as uplink interfaces can be controlled to enter into the electricity-saving state, thereby realizing a 'non-full-time access' electricity-saving effect; and furthermore, after the interface modules corresponding to the uplink interfaces enter into the electricity-saving state, the uplink interfaces are no long under an Up state, thereby being free from influencing a superior device to carry out an electricity-saving measurement as well as supporting network-rank electricity-saving control.

Description

technical field [0001] The invention relates to power saving technology, in particular to a digital communication device capable of realizing power saving, a power saving control device and a power saving control method. Background technique [0002] Data communication equipment (such as switches, routers, etc.) as the node equipment of the network architecture, constitutes various digital communication networks ranging from home SOHO networks to the Internet. Due to the wide distribution and large range of digital communication networks, logarithmic Effective power saving measures for communications equipment can produce a very good scale effect, thereby reducing energy consumption significantly, and then generating considerable economic benefits by reducing energy consumption. [0003] In the prior art, the chip-level power-saving measures of data communication equipment have been practically applied. For example, the CPU chip of the data communication device has a frequen...

Problems solved by technology

Specifically, among the interfaces of data communication equipment, the interfaces connected to lower-level equipment such as switches and PCs are downlink interfaces, and the interfaces connected to upper-level equipment such as switches and routers are uplink interfaces. As long as the upper-level equipment is not closed, even all downlink interfaces The lower-level devices connected to the interface are all closed, and the uplink interface will still be in the Up state, and the real-time preparation will be used as the IP access port to provide data traffic services for the lower-level devices connected to the downlink interface, which will cause unnecessary power consumption. The power-saving effect of the CPU also has a certain impact, so that the device-level power-saving measures cannot achieve the best device-level power-saving effect; power saving measures at the network level cannot be achieved, such as figure 2 As shown, when all the PCs connected to the downlink interfaces of the switch are turned off, the uplink interface connected to the router is still in the Up state, so that the corresponding downlink interface of the router is also in the Up state, and it is impossible to take power saving measures for the corresponding downlink interface. measures, so that the best power-saving effect cannot be achieved for the router

[0007] 2. The CPU chip, which is the center of power-saving control, must be powered on and monitored no matter whether it is down-frequency or in a dormant state, and the power consumption of the CPU chip itself accounts for a large proportion of the total power consumption of digital communication equipment. Therefore, in the prior art, the device-level power-saving measures using the CPU as the power-saving control center cannot achieve the best device-level power-saving effect.
