Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The white box switch is a flexible and efficient network device, and a user can deploy different applications and services with personalized characteristics on the same hardware system according to needs. The software decoupling module has the function of decoupling software, can reduce the cost and improve the use flexibility, constructs different components and modules for the special requirements of manufacturers, and is popular among various manufacturers and data centers. Particularly in large data centers. The switch has the most important function of forwarding network traffic, and in a data center environment, because data traffic is large, an optical module and an optical fiber device are generally used to transmit data between switches or between a switch and a server by using an optical signal as a carrier.
When the switch transmits data, the optical module is required to convert an electric signal in the switch into an optical signal, the optical signal is required to be converted into the electric signal again after receiving the electric signal, and each port needs one optical module, so that the overall power consumption of the switch caused by the power consumption of the optical module is greatly increased, the number of the ports is increased, and the increased power is increased. However, under the current trends of energy conservation, environmental protection and energy waste reduction, no corresponding scheme is adopted to reasonably arrange and deploy the optical modules, so that the module loss is reduced and the energy waste is reduced on the basis of not influencing the system operation.
Meanwhile, in a data center, all switch links can transmit network traffic under full load ideally, and the utilization rate of all port links is 100%. However, in actual operation, in order to prevent sudden failure or bandwidth increase, links in a data center are designed to be redundant to some extent, and there is often more than one data link connecting two devices. In addition, in some cases, the utilization rate of the link bearing some services is low, and the link can be migrated to other links. But in the above cases, the link is normally still on and made immediately operational, which also causes extra power consumption. Even in the case of a link backup, the ports are simply turned off inside the switch, and the light emitters inside the optical modules are turned off, and the internal power supply of the optical modules is not processed.
The embodiment of the application provides an energy-saving control method of a white box switch, which is used for solving the technical problems that optical modules cannot be reasonably arranged and deployed when the existing white box switch is used, and on the basis of not influencing the operation of a system, the module loss is reduced, and the energy waste is reduced.
The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an energy saving control method of a white box switch according to an embodiment of the present application. As shown in fig. 1, a method for controlling energy saving of a white box switch provided in an embodiment of the present application mainly includes the following steps:
and step 101, judging the current link states of all links.
In the embodiment of the application, the white box switch transmits data in the form of optical signals through an internal optical module and an optical fiber device. The energy-saving control is carried out on the white box switch, firstly, software and hardware technical support is needed, and all port optical modules support independent control of a power supply by using a VR voltage control chip. And the power on and power off of the individual optical modules can be controlled through software in a mode that NOS software is used for operating VR device registers.
In the embodiment of the present application, the energy consumption of the switch is adjusted by defining the link state of the white box switch, and specifically three link states are defined: normal state, backup state, off state. The white box switch realizes marking and monitoring of all link states through corresponding program control, and specifically judges the link states through the flow conditions forwarded by the links.
In the embodiment of the present application, all links of the white box switch support the manual setting state as well as the automatic setting state. The manual setting state realizes the corresponding function of the white box switch by adjusting the link state through technicians, does not participate in automatic judgment and conversion of the state, and the state of the white box switch is always kept unchanged, and the energy consumption of the white box switch can be adjusted and controlled according to the method and the process provided by the embodiment of the application unless the state is set to be the automatic setting state again.
And 102, monitoring the flow of each link in a preset time period in real time, and controlling each link to be switched among a normal state, a backup state and a closed state based on a preset flow threshold value.
In the embodiment of the application, the forwarding condition of the traffic on each link is monitored through a program capable of carrying out traffic statistics, and the link is switched among a normal state, a backup state and a closed state through whether the traffic forwarding reaches a corresponding traffic threshold value within a preset time period.
Specifically, in a normal use state, link flow is forwarded normally, and an optical module power supply is normal; under the condition of backup, the internal port of the switch is closed, and the whole power supply is reduced; in the shutdown case, the switch internal ports are closed.
Firstly, whether the flow of a link to be controlled within a first preset time threshold is lower than a first preset flow threshold is detected, if the flow is lower than the first preset flow threshold, namely, only a small amount of flow exists, a Mac table is searched through a two-layer port and a routing table is searched through a three-layer port of the white box switch so as to determine other alternative links existing on the white box switch, and the flow is forwarded to the alternative links. At the same time, the link is directly closed. And the system background judges that the link on the white box switch is switched from the normal state to the backup state.
It should be noted that the system adjusts the VR chip to reduce the power consumption of the whole device, and transfers the original traffic to an alternative link in a Redirect or Mirror image manner. Then, backing up the configuration information when the link to be controlled is closed to the system; wherein, the backup information comprises: mac table information, routing table information, VLAN information. And the flow is directly issued after being restarted when the related flow is increased. If no alternative link is found, the normal usage mode is maintained unless an alternative link is found to ensure that normal traffic is not interrupted.
If the link has no flow or only receives the broadcast message which is not required to be forwarded, the port link is directly closed, and the VR chip is adjusted to reduce the power consumption.
Secondly, whether the flow of the link to be controlled within a second preset time threshold is lower than a second preset flow threshold is judged, and if the flow of the link to be controlled within the second preset time threshold is lower than the second preset flow threshold, the flow of the link to be controlled within the second preset time threshold is judged. The control link on the computer is switched from the backup state to the closed state, and the background of the system records and marks the situation.
And then, after the port is automatically converted into a backup or closed state, the flow transferred by the Redirect redirection or Mirror image function is still monitored, and if the monitored flow rises and rises to a third preset flow threshold, for example, 15% of the flow, the closed state link is restored to the backup state. When the flow further rises to a fourth preset flow threshold, for example, 30% of bandwidth, or when the flow is too large and affects the data forwarding of other links, the backup link information in the system is read, and is re-issued, a port in the backup state is opened, the Redirect redirection or Mirror image of the flow by the system is cancelled, and the normal use state of the link is recovered.
In the embodiment of the present application, for a case where traffic suddenly rises, in order to prevent service interruption, at this time, a link needs to be immediately converted from a closed state to an open state, because the opening of the link relates to optical module control, generally, this control process is implemented by a low-speed bus, for example, an Inter-Integrated Circuit (IIC) bus, where the speed is much slower than the speed of a port inside a switch, a buffer area may be set in an internal memory of the switch, and if an optical module does not normally operate after the port is opened, a content that needs to be forwarded may be stored in the buffer area, and the optical module continues to be forwarded after the optical module normally operates.
And 103, controlling the optical module to be opened or closed according to the link state switching condition of each link.
In the embodiment of the present application, the link state of the white box switch is controlled in step 102, and to realize energy saving, the optical module also needs to be adjusted and controlled, and the optical module includes a light emitting end and a receiving end, which respectively correspond to the emission and the reception of the optical signal.
Specifically, when the white box switch link is switched among a normal state, a backup state, and an off state, the corresponding optical modules are turned on or off differently.
In the embodiment of the application, the link on the white box switch is switched from the normal state to the backup state, and when the traffic is forwarded to the alternative link, the light emitting end of the optical module of the link is turned off. When the link has no flow or only receives the broadcast message which is not required to be forwarded, the light-emitting end of the optical module of the link is also closed.
And if the flow of the link to be controlled in the second preset time threshold is lower than the second preset flow threshold, closing the whole power supply of the optical module, namely switching the link to a closed state.
And if the monitored flow rate rises and reaches a third preset flow rate threshold value, the VR chip turns on the power supply of the optical module, and the link is restored to the backup state from the off state.
According to the energy-saving control method for the white box switch, the three link states of all links on the white box switch are recorded, the flow forwarding condition of each link in a preset time period is monitored, and each link of the white box switch is switched among the three states. The energy consumption of the white box switch is saved by automatically closing the link and the optical module when the white box switch is idle, and the idle link flow is forwarded to the replaceable link by setting, so that the link resources on the white box switch are fully utilized, and the waste of the resources is reduced. The light-emitting end of the optical module is turned off in idle time or the power supply of the optical module is turned off integrally, so that the optical module is not in an on state for a long time, the loss of the optical module is reduced, and the service life of the optical module is prolonged. The energy-saving control method of the white box switch provided by the embodiment of the application realizes the maximum energy-saving control on the basis of not influencing the normal operation of the system.
