Based on the energy consumption map, a first transmission path having an energy consumption value smaller than that of the second transmission path can be obtained. Therefore, the first transmission path with a smaller energy consumption value can be obtained based on the energy consumption map, so that the energy consumption of the transmission target service is reduced, and the cost of transmitting the data of the target service is reduced.

Detailed Description

The following describes a conventional technology and a path generating method provided by an embodiment of the present application with reference to the accompanying drawings.

Referring to fig. 1, a schematic diagram of a network architecture according to an embodiment of the present application is shown. Network 100 includes network device 101-network device 108. Wherein network device 101 is connected to network device 102, network device 103, and network device 104, respectively. Network device 102 is connected to network device 101, network device 103, and network device 104, respectively. Network device 103 is connected to network device 101, network device 102, network device 104, network device 105, and network device 106, respectively. Network device 104 is connected to network device 101, network device 102, network device 103, network device 105, and network device 106, respectively. Network device 105 is connected to network device 103, network device 104, network device 106, network device 107, and network device 108, respectively. Network device 106 is connected to network device 103, network device 104, network device 105, network device 107, and network device 108, respectively. Network device 107 is connected to network device 105, network device 106, and network device 108, respectively. Network device 108 is connected to network device 105, network device 106, and network device 107, respectively. The transmission path obtained by calculating the service demand of the service based on the available resources of the network by the computing equipment is as follows: network device 101→network device 103→network device 104→network device 106→network device 108. The transmission path of network device 101→network device 103→network device 104→network device 106→network device 108 may not be a transmission path with a small energy consumption value. The energy consumption may be large when data of traffic is transmitted based on network device 101→network device 103→network device 104→network device 106→network device 108.

Therefore, the first transmission path with a smaller energy consumption value can be obtained based on the energy consumption map, the data of the target service is transmitted by adopting the first transmission path, the energy consumed by transmitting the data of the target service can be reduced, and the cost for transmitting the data of the target service is reduced.

Fig. 3 is a flowchart of a path generating method according to an embodiment of the present application. Referring to fig. 3, the method may include S301-S302.

S301: and acquiring an energy consumption map.

The energy consumption map is a map indicating the energy consumption situation of the network. The energy consumption map includes basic information. The basic information comprises network topology information of a network, energy consumption information of network equipment in the network, key performance indicator (key performance indicators, KPI) information and flow information acquired in real time.

The network topology information of the network is used to indicate the topology of the network. The topology of the network includes the connection relationships between the devices that make up the network. In one possible implementation, the topology information of the network further includes status information of the network device and fault information. The state information includes an on state and an off state of the network device. The fault information includes information such as the degree of fault of the network device and the location of the fault. As one example, the failure of the network device includes a failure of an energy consumption anomaly.

The energy consumption information of the network equipment is used for indicating the energy consumption condition of the network equipment. The network device includes at least one port. The power consumption information of the network device includes one or more of a device power consumption value and a port power consumption value.

The device energy consumption value is used for measuring the energy consumption degree of the whole network device. The device energy consumption value is the energy consumption information of the granularity of the device. In one possible implementation, the device power consumption value may be affected by the device transmission traffic. The device energy consumption value comprises a first energy consumption value and a second energy consumption value. The first energy consumption value is the energy consumption value of the basis of the operation of the network equipment. The first energy consumption value is an energy consumption value of the non-bearing flow after the network equipment is started. For example, the first energy consumption value includes energy consumption values generated by rack start-up, indicator light illumination, fan operation, and the like of the equipment. The second energy consumption value is an additional energy consumption value generated by the network device bearing traffic compared with the first energy consumption value, namely an increment of the energy consumption value of the network device bearing traffic relative to the first energy consumption value.

As an example, the second energy consumption value is related to traffic carried by the network device. The second energy consumption value is determined based on the real-time traffic of the network device and the energy consumption coefficient of the network device. For example, the energy consumption coefficient is an energy consumption value corresponding to each unit flow. The second energy consumption value is the product of the real-time flow of the network device and the energy consumption coefficient of the network device. It should be noted that in one possible implementation, the energy consumption coefficient of the network device is only related to the network device. For example, different models of network devices have corresponding energy consumption coefficients. In another possible implementation, the energy consumption coefficient of the network device is also related to the traffic carried by the network device. For example, the first equation can describe a correspondence between the energy consumption coefficient of the network device and the traffic carried by the network device. Based on the first equation and the real-time traffic of the network device, the energy consumption coefficient of the network device can be obtained. For another example, traffic of different ranges of network devices has a correspondence with energy consumption coefficients of different network devices. For example, when the traffic carried by the network device is in the range of 0-10 gigabytes per second (Gb/s), the energy consumption coefficient of the corresponding network device is 1. When the flow carried by the network equipment is in the range of 10Gb/s-20Gb/s, the energy consumption coefficient of the corresponding network equipment is 0.75. The network device or the device for calculating the path can pre-store the corresponding relation between the flow of the network device and the energy consumption coefficient of the network device, and determine the corresponding energy consumption coefficient based on the acquired real-time flow of the network device, so as to obtain a second energy consumption value.

The port energy consumption value indicates an energy consumption condition of at least one port in the network device. The port energy consumption value is the energy consumption information of the port granularity.

In one possible implementation, the port power consumption value may be affected by port traffic. The port power consumption values include a third power consumption value and a fourth power consumption value. The third energy consumption value is the energy consumption value of the basis of port operation. The third energy consumption value is the energy consumption value of the non-bearing flow after the port is opened. For example, the third energy consumption value includes an energy consumption value generated by starting a single board of the port, lighting an indicator light, and the like. The fourth energy consumption value is an additional energy consumption value generated by the port bearing flow compared with the third energy consumption value. The fourth energy consumption value is the increment of the energy consumption value of the port bearing flow relative to the third energy consumption value.

As an example, the fourth energy consumption value is related to traffic carried by the port. The fourth energy consumption value is determined based on the real-time traffic of the at least one port and the energy consumption coefficient of the at least one port. For example, the energy consumption coefficient is an energy consumption value corresponding to each unit flow. The fourth energy consumption value is the product of the real-time flow of the port and the energy consumption coefficient of the port. It should be noted that in one possible implementation, the energy consumption coefficient of the port is only related to the port. Different types of ports, or ports belonging to different network devices, have corresponding energy consumption coefficients. In another possible implementation, the energy consumption coefficient of a port is also related to the traffic carried by the port. For example, the second equation can describe the correspondence between the energy consumption coefficient of the port and the traffic carried by the port. Based on the second equation and the real-time flow of the port, the energy consumption coefficient of the port can be obtained. For another example, the traffic of the ports in the different ranges has a correspondence with the energy consumption coefficients of the different ports. For example, when the flow carried by the port is in the range of 0-10Gb/s, the energy consumption coefficient of the corresponding port is 2. When the flow carried by the port is in the range of 10Gb/s-20Gb/s, the energy consumption coefficient of the corresponding network equipment is 1. The network device or the device for calculating the path can pre-store the corresponding relation between the flow of the port and the energy consumption coefficient of the port, and determine the corresponding energy consumption coefficient based on the acquired real-time flow of the port, so as to obtain a fourth energy consumption value.

The KPI information includes one or more of a bandwidth utilization upper limit and a device resource utilization upper limit.

The bandwidth utilization is the ratio of the bandwidth flow of the actual operation of the link to the maximum bandwidth capacity of the link. The bandwidth utilization upper limit value is the maximum value of the bandwidth utilization. The bandwidth utilization upper limit value is used to limit the bandwidth utilization to prevent excessive traffic. It should be noted that in some possible implementations, the increment of the energy consumption value gradually decreases as the bandwidth utilization increases, while other conditions are unchanged. Specifically, for example, the energy consumption value at which the bandwidth utilization increases from 0 to 20% is larger than the energy consumption value at which the bandwidth utilization increases from 50% to 70%. However, too high bandwidth utilization also tends to affect the normal transmission of the targeted traffic. Therefore, the energy consumption value of the transmission target service can be reduced on the premise that the normal transmission of the target service can be ensured to a certain extent by setting the upper limit value of the bandwidth utilization rate.

The equipment resource utilization rate is the ratio of the resources occupied by the actual operation of the equipment to the total resources of the equipment. The device resource utilization upper limit value is the maximum value of the device resource utilization. The upper limit value of the utilization rate of the equipment resources is used for limiting the utilization rate of the equipment resources and preventing the excessive use of the equipment resources from affecting the normal transmission of the target service.

The traffic information acquired in real time can represent the real-time situation of the traffic distribution of the network. In one possible implementation, the traffic information acquired in real-time includes one or more of real-time traffic of the network device and real-time traffic of the at least one port. The real-time traffic of the network device is traffic transmitted by the network device in real time. Specifically, the real-time traffic of the network device is the sum of the traffic transmitted by the network device. The real-time traffic of the network device is the traffic of the device granularity. The real-time flow of the port is the flow transmitted by the port in real time. Specifically, the real-time traffic of a port is the sum of traffic transmitted by the port. The real-time traffic of the port is traffic of the port granularity.

The embodiment of the application is not limited to a specific implementation mode for acquiring the energy consumption map. In one possible implementation, the device having the path calculation function is capable of acquiring the energy consumption map generated and transmitted by the other device, and obtaining the first transmission path based on the acquired energy consumption map. In another possible implementation, the device with road calculation function is capable of generating an energy consumption map and deriving the first transmission path based on the generated energy consumption map.

For another example, the device that generates the energy consumption map may acquire network topology information of the network, energy consumption information of the network device, and traffic information from other management control devices or management control systems. As another example, the device that generates the energy consumption map is a management control device, and the network device can send the base information to the device that generates the energy consumption map based on a protocol or report the base information through an interface connected to the device that generates the energy consumption map.

For example, the device that generates the energy consumption map can obtain KPI information input by the user and energy consumption information of the network device.

Third kind: the device generating the energy consumption map can obtain the basic information based on an algorithm.

For example, the device that generates the energy consumption map can obtain the energy consumption information of the network device based on an algorithm. As an example, the algorithm may be trained in advance using training data including energy consumption data and flow data. The device for generating the energy consumption map can obtain energy consumption information based on the trained algorithm and the acquired flow information of the network device.

The energy consumption of the network can be considered based on the first transmission path determined by the energy consumption map, and the energy consumption value of the obtained first transmission path is smaller than that of the second transmission path.

Wherein the energy consumption value is used to measure the energy consumed for transmitting the target traffic based on the first transmission path. The energy consumption value includes, for example, a consumed energy value, a carbon emission amount, an electric charge, and the like.

The embodiment of the application does not limit the way of triggering the first transmission path for determining the transmission target service based on the energy consumption map. In one possible implementation, in response to obtaining a user-triggered routing instruction, the device determines a first transmission path for the transmission target traffic based on the energy consumption map. In another possible implementation, in response to the update of the base information included in the energy consumption map, the device determines a first transmission path for the transmission target service based on the updated energy consumption map. As an example, after acquiring the updated energy consumption map, the device determines a first transmission path of the transmission target service based on the updated energy consumption map at intervals of a preset period. Therefore, the first transmission path can be calculated after the energy consumption map is not changed any more, so that the obtained first transmission path is more accurate, and the calculation times of the first transmission path triggered by frequent change of the energy consumption map are reduced.

The embodiment of the application provides two possible specific implementation modes for determining the first transmission path of the target service according to the energy consumption map.

Mode one: the target service has an energy consumption requirement. And obtaining a first transmission path according to the equipment information of the source equipment, the equipment information of the target equipment, the energy consumption requirement of the target service and the energy consumption map.

Wherein the device information of the source device is used to identify the source device. The device information of the source device is, for example, a device identification of the source device or a network address of the source device. The device information of the destination device is used to represent the destination device. Device information of the destination device, such as a device identification for the destination device, or a network address for the destination device.

In one possible implementation, the source device of the second transmission path is identical to the source device of the first transmission path, and the destination device of the second transmission path is identical to the destination device of the second transmission path. The device for calculating the path can obtain device information of the source device based on the source device of the second transmission path. The device for calculating the path can obtain device information of the destination device based on the destination device of the second transmission path.

The energy consumption requirement of the target service indicates a requirement in terms of energy consumption for transmitting the target service. As an example, the energy consumption requirement of the target traffic is that the energy consumption value of the transmission target traffic is the minimum. As another example, the energy consumption requirement of the target traffic is that the energy consumption value of the transmission target traffic is less than a threshold value.

The method for obtaining the first transmission path is not limited in the embodiment of the application. As an example, the device for calculating the path can obtain the first transmission path using the path algorithm according to the device information of the source device, the device information of the destination device, the energy consumption requirement of the target service, and the energy consumption map. As another example, the path computation device can obtain the candidate transmission path based on the device information of the source device, the device information of the destination device, and the energy consumption map, and then select the candidate transmission path satisfying the energy consumption requirement of the target service as the first transmission path.

Mode two: the target service has an energy consumption requirement and a service requirement. And obtaining a first transmission path according to the equipment information of the source equipment, the equipment information of the target equipment, the energy consumption requirement of the target service, the service requirement of the target service and the energy consumption map.

The traffic demand of the target traffic indicates the demand in terms of transmission of the transmission target traffic. Traffic demands such as service level agreement demands, traffic distribution demands, etc.

In one possible implementation, the source device of the second transmission path is identical to the source device of the first transmission path, and the destination device of the second transmission path is identical to the destination device of the second transmission path. The device information of the source device and the device information of the destination device can be obtained based on the second transmission path.

In another possible implementation, the service requirement includes device information of the source device and device information of the destination device. The device for calculating the path can obtain the device information of the source device and the device information of the destination device based on the service requirement.

The method for obtaining the first transmission path is not limited in the embodiment of the application. As an example, the path computation device can obtain the first transmission path by using a path computation algorithm according to the device information of the source device, the device information of the destination device, the energy consumption requirement of the target service, the service requirement of the target service, and the energy consumption map. As another example, the path computation device can obtain the candidate transmission path based on the device information of the source device, the device information of the destination device, and the energy consumption map, and then select the candidate transmission path satisfying the energy consumption requirement of the target service and satisfying the service requirement of the target service as the first transmission path.

In the case that the device that determines the first transmission path based on the energy consumption map is the management control device, after obtaining the first transmission path, the management control device further issues configuration information to a plurality of network devices in the network. The configuration information indicates that the target traffic transmits data through the first transmission path. In one possible implementation, the management control device sends configuration information to the network device on the first transmission path.

In the network, the data of the target service is transmitted based on the first transmission path, which affects the energy consumption of the network device, the energy consumption map including the flow distribution in the network, and the like. After the first transmission path is obtained, the energy consumption map can also be adjusted based on the first transmission path update.

In one possible implementation manner, the energy consumption map is adjusted based on the basic information after the target service is transmitted through the first transmission path, and specifically includes the following two steps:

b1: and acquiring basic information of the target service after data transmission through the first transmission path.

And acquiring basic information after the network transmits the data of the target service through the first transmission path. The method for obtaining the basic information in B1 is similar to the method for obtaining the basic information in A1, please refer to the above, and details are not repeated here.

B2: and updating the energy consumption map according to the basic information after the target service transmits the data through the first transmission path.

And updating the energy consumption map based on the obtained updated basic information.

In some possible implementations, the device that determines the first transmission path based on the energy consumption map has a display function. The device is capable of displaying one or more of a first transmission path, an energy consumption value of a transmission target service, indication information for indicating a relationship of the energy consumption value of the first transmission path and the energy consumption value of a second transmission path, status information of a network device for transmitting the target service, and a network device or a link adjusted from an on state to an off state.
