Embodiment 1

[0063] An embodiment of the present invention provides a method for network energy saving, such as figure 2 As shown, the method includes:

[0064] Step 201: monitor the bandwidth utilization of the energy-aware link;

[0065] Among them, many nodes in the network layer are set redundantly to ensure the reliability of the network. When the network is not busy, the bandwidth utilization rate of most nodes is very low. Therefore, the operation of step 201 realizes that each energy-aware node Monitor the bandwidth utilization of the energy-aware link to facilitate subsequent triggering of energy-saving operations. For example: figure 1 Energy-aware node A in energy-aware link group 1 can monitor the bandwidth utilization of link AB and link AC; energy-aware node B in energy-aware link group 1 can monitor link AB and link Bandwidth utilization on road BC; energy-aware node B in energy-aware link group 2 (that is, the set of links among node B, node D, and node E) can monitor l...

Embodiment 2

[0101] The embodiment of the present invention provides a method for network energy saving. This method is similar to the method provided in Embodiment 1. The difference is that the method provided in this embodiment is based on Embodiment 1. A technical method that may form a loop in the calculated next hop, that is, to determine that each new next hop is a node in the energy-aware link group that wants to save energy, so that the found replacement link is still a link in the group path, does not involve devices outside the group, and will not form a backup path including loops.

[0102] At the same time, optional operations are added to the method, such as: operations for managers to configure nodes in the energy-aware link group, and operations for communicating among nodes in the energy-aware link group to obtain mutual information.

[0103] For details, see image 3 As shown, the method includes:

[0104] Step 301: Receive and configure energy-saving data, the energy-sa...

Embodiment 3

[0124] The embodiment of the present invention provides a method for network energy saving, which is similar to the method provided in Embodiment 1, the difference is that the execution subject in Embodiment 1 is a node with a relatively low priority in the energy-aware link group, It is necessary to receive the control of a node with a higher priority (such as an energy-aware master node). The example in this embodiment is a network energy-saving method in which the energy-aware master node acts as the execution subject. see Figure 5 As shown, the method includes:

[0125] Step 501: Monitor the bandwidth utilization of the energy-aware link;

[0126]Step 502: When it is detected that the bandwidth utilization rate of the energy-aware link is lower than the energy-saving threshold, judge the next hop of each route according to the locally stored Interior Gateway Protocol (IGP) routing database and priority information: Whether the next hop is the node in the energy-aware li...

Abstract

The embodiment of the invention discloses a network energy-saving method and a device. The method is characterized in that a bandwidth utilization rate of an energy perception link is monitored, when the bandwidth utilization rate is lower than an energy-saving threshold value, the judgment for whether energy conservation is carried out or not for the energy perception link is triggered, when a next hop of a route is a node in an energy perception link group in which the energy perception link requiring the energy conservation stays, the routing calculation is carried out according interior gateway protocol (IGP) routing data excluding the energy perception link requiring the energy conservation; when each next hop in the group works out a novel next hop, each novel next hop is stored to a reserved route; and after an energy-saving message transmitted by an energy perception main node is received, the energy conservation is executed, and intelligent energy conservation for some links can be realized through the network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for energy saving of a network. Background technique [0002] The operation of the Internet consumes a large amount of electric energy. With the continuous expansion of the network scale and the rapid growth of business volume, the network's demand and consumption of electric energy continue to increase, which has exerted tremendous pressure on the operating cost of the network and the ecological environment. Therefore, network energy-saving technology has been paid more and more attention. [0003] The reliable transmission of data used to be the main goal of Internet design and deployment. In order to deal with network failures and carry sudden network traffic, the Internet needs to set up many redundant links during deployment, and provide each link with much higher than average link capacity. The bandwidth of the traffic. The deployment of ...
