[0034] In order for those skilled in the art to more clearly understand the technical solutions of the present disclosure, the application scenarios of the present disclosure scheme will be described first as follows.
[0035] Network devices, such as OTN, SPN, switches and routers, etc., usually include multiple cross board cards responsible for processing and forwarding network traffic. The cross board cards are connected to the processors through high-speed data buses and work cooperatively with other board cards to ensure efficient forwarding of network data. However, the existing connection mode of the cross board cards inside the network device may cause the network traffic to be processed and forwarded to be mismatched with the performance of the cross board cards, resulting in waste of electric energy of the cross board cards and low energy-saving efficiency of the network device.
[0036] For example, but according to the judgment of the performance of the cross board cards, the processing capacity of the cross board cards is usually 800G-1.6T. If the current network traffic to be processed and forwarded is 30G, at this time, a cross board card with a processing capacity of 800G is in a wake-up mode, but the current service only occupies 30G of the processing capacity of this cross board card, and the remaining 770G of the processing capacity of this cross board card is in an idle state, but this cross board card needs to remain in a wake-up state to complete the forwarding and processing of service data. Therefore, it will cause excessive redundancy of the processing capacity of the cross board card, waste of electric energy, and decrease of energy-saving efficiency.
[0037] To solve the above technical problems, the present disclosure provides a network device. In the present disclosure, the network device comprises a controller, a service interface board, a plurality of cross modules and a power module connected with each cross module; the cross module is obtained by splitting the cross board card; the service interface board is connected with each cross module; the controller is connected with the power module, the service interface board and each cross module respectively. Splitting the cross board card into a plurality of cross modules can reduce the minimum unit of processing and forwarding network traffic, and avoid excessive redundancy of cross board card processing capacity. At the same time, connecting each cross module with the power module can realize independent control of the power consumption of the smaller unit cross module. Therefore, the energy efficiency of the network device can be improved.
[0038] In order to make the purpose, technical scheme and advantages of the present disclosure more obvious, the example embodiments according to the present disclosure will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all embodiments of the present disclosure, and it should be understood that the present disclosure is not limited by the example embodiments described here.
[0039] Figure 1 A structural schematic diagram of a network device provided by the present disclosure is shown in FIG. 1. As shown in the figure, the network device comprises a controller 100, a service interface board 200, a plurality of cross modules 300 and a power module 400 connected with each cross module. Figure 1
[0040] The cross module 300 is obtained by splitting the cross board card 03.
[0041] Specifically, in the embodiment, the size of the processing capacity of the cross module 300 is smaller than that of the cross board card 03. For example, in the actual production process at present, the processing capacity of the produced cross board card 03 is in the range of 800G-1.6T, if the processing capacity of a certain cross board card 03 is 800G, at this time, the cross board card 03 is split into 10 cross modules 300 with the same processing capacity, and the processing capacity of each cross module 300 is 80G. In this way, the minimum unit of processing and forwarding network traffic can be reduced, and the processing capacity of the cross board card can be avoided to be excessive redundant.
[0042] The service interface board 200 is connected with each cross module 300.
[0043] Specifically, each cross module 300 has the same function, has the ability to process and forward network traffic, can process a part of network traffic, and there is no physical dependence between each cross module 300, which can be flexibly put into sleep or wake up according to the actual network traffic demand. Therefore, the service interface board 200 can be connected with each cross module 300 to realize the service demand.
[0044] The controller 100 is connected with the power module 400, the service interface board 200 and each cross module 300 respectively.
[0045] Specifically, the power module 400 supplies power for each cross module 300, and the controller 100 can control the sleep or wake-up of the power module 400. In the embodiment, each cross module 300 is connected with the power module 400 respectively, so that the independent control of the power consumption of the smaller unit cross module can be realized, and the problem of power waste of the cross board card 03 can be avoided. The controller 100 is connected with the service interface board 200 and each cross module 300 respectively, so that the network traffic can be controlled to flow from the service interface board 200 to the cross module 300, and the network traffic can be controlled to flow from the cross module 300 to the service interface board 200, so as to realize the forwarding and processing of the network traffic.
[0046] In the disclosure, the network device comprises a controller, a service interface board, a plurality of cross modules and a power module connected with each cross module; the cross module is obtained by splitting the cross board card; the service interface board is connected with each cross module; the controller is connected with the power module, the service interface board and each cross module respectively. Splitting the cross board card into a plurality of cross modules can reduce the minimum unit of processing and forwarding network traffic, and avoid the excessive redundancy of the processing capacity of the cross board card. At the same time, each cross module is connected with the power module respectively, so that the independent control of the power consumption of the smaller unit cross module can be realized. Therefore, the energy saving efficiency of the network device can be improved.
[0047] Figure 2 Another structural schematic diagram of a network device provided by the disclosure is provided. As shown in Figure 2 The network device comprises a backplane bus 500.
[0048] Each cross module 300 is connected with the power module 400 through the backplane bus 500 of the network device; the service interface board 200 is connected with each cross module 300 through the backplane bus 500; and the controller 100 is connected with the power module 400, the service interface board 200 and each cross module 300 respectively through the backplane bus 500.
[0049] Specifically, the backplane bus 500 is a common channel for transmitting data signals, which is used for connecting the communication signals of various modules of the network device, that is, all the modules in the network device can be connected through the backplane bus 500. It connects the network device, determines the data exchange capacity and packet forwarding rate, and at the same time, the backplane bus connects the power module 400 to supply power for each cross module 300, and has the function of power supply. And using the backplane bus 500 can improve the neatness of the internal circuit of the network device, which is conducive to the heat dissipation of the network device.
[0050] Figure 3Another structural schematic diagram of a network device provided by the present disclosure is shown in FIG. 4. As shown in FIG. 4, the network device includes a plurality of power supply devices 04. Figure 3 The power supply device 04 includes a plurality of power supply modules 400.
[0051] The power supply module 400 connected to each cross module 300 belongs to the same power supply device 04.
[0052] Specifically, in the present embodiment, the plurality of power supply modules 400 can belong to the same power supply device 04, i.e., each power supply module 400 is a submodule in the power supply device 04. Such a setting mode can reduce the processing cost of the power supply device.
[0053] The power supply device 04 further includes a switching device 410 connected to each power supply module 400. The switching device 410 is connected to the cross module 300 corresponding to each power supply module 400.
[0054] Specifically, the controller 100 sends a control signal to control the state of the switching device 410, thereby realizing the control of the sleep or wake-up of the cross module 300. Moreover, the setting of the switching device 410 can also play a role in protecting the power consumption of the cross module 300.
[0055] Further, the switching device 410 can be a relay.
[0056] In addition, the switching device 410 can also be other transistor electronic switching devices.
[0057] Figure 4 Another structural schematic diagram of a network device provided by the present disclosure is shown in FIG. 4. As shown in FIG. 4, the network device includes a plurality of power supply devices 04. Figure 4 The power supply device 04 includes a plurality of power supply modules 400.
[0058] The power supply module 400 connected to each cross module 300 belongs to different power supply devices 04.
[0059] Specifically, the power supply module 400 can be a plurality of power supply devices, i.e., the power supply module 400 connected to each cross module 300 is an independent power supply device 04. Such a setting mode is conducive to the management of the power supply device.
[0060] In a possible implementation, each cross module 300 is a sub-cross board card with a processing capability less than the cross board card 03.
[0061] Specifically, in the present embodiment, each cross module 300 is a sub-cross board card with a processing capability less than the cross board card 03, which is an independent entity.
[0062] In a possible implementation, each cross module 300 is a module divided in the cross board card 03 with a processing capability less than the cross board card 03.
[0063] Specifically, in the embodiment, the physical state of the cross board card 03 is not changed, and the division of each cross module 300 is modularized by software simulation.
[0064] For example, a cross board card is virtually divided into two cross modules, the bottom hardware, data processing, service logic processing and other functions of the cross board card are divided into two parts, and each part is a cross module. The two modules communicate and work together through a defined software interface.
[0065] In a possible implementation, the processing capabilities of the plurality of cross modules 300 are the same.
[0066] Specifically, when the cross board card 03 splits the plurality of cross modules 300, the plurality of cross modules 300 can be split into cross modules with the same processing capability. In this way, the control precision is improved, and the selection logic design of the controller 100 for the cross modules is facilitated. In addition, the processing cost can be reduced by pre-splitting the cross modules.
[0067] Figure 5 Another structural schematic diagram of a network device provided by the present disclosure is provided. As shown in the figure, the network device further comprises a plurality of prompt devices 600 connected with the controller 100. Figure 5
[0068] Each prompt device 600 is used to prompt the running state of the cross module 300 corresponding to the prompt device.
[0069] Specifically, the prompt device 600 can remind the operator of the current running state of the corresponding cross module 300, i.e., the cross module 300 is currently in a wake-up state or a sleep state, which is conducive to the maintenance of the network device by the operator. The prompt device 600 can be an indicator, a buzzer, etc.
[0070] Further, the controller 100 can be connected with each prompt device 600 through the backplane bus 500 of the network device. Using the backplane bus 500 can improve the neatness of the internal circuit of the network device, which is conducive to the heat dissipation of the network device.
