Description

Technical Field

[0001] The present application relates to the field of edge computing technology, and in particular to a method, device and storage medium for sharing a computing function module. Background Art

[0002] Road test edge computing equipment is aimed at the general perception needs of multiple categories of smart highways, providing perception data services with relatively low latency and higher accuracy. However, in traditional technologies, tasks with high latency requirements are mainly completed by the local computing power of edge computing equipment. If the computing power reserved during planning and construction is insufficient, it will lead to insufficient business processing capabilities.

[0003] Currently, multiple edge computing devices can be coordinated through network devices (such as routers), and other nearby edge computing devices with limited computing resources can reuse idle computing resources for task computing. However, in this process, the router will store a large amount of information about edge computing devices, occupying the router's storage resources. Summary of the invention

[0004] The present application provides a method, device and storage medium for sharing a computing function module, which are used to solve the problem of a large amount of router storage resources being occupied.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In the first aspect, the present application provides a method for sharing a computing function module. In the method, the logical distance of multiple first computing function modules is obtained, and the logical distance is used to reflect the time consumed by the computing function module to process a business request. The multiple first computing function modules are deployed in at least one edge computing device. Based on the logical distance of the multiple first computing function modules, at least one second computing function module is determined from the multiple first computing function modules, and the logical distance of the second computing function module is less than a preset distance threshold. Function registration information of at least one second computing function module is sent to a second network device.

[0007] Based on the above technical solution, the logical distances of multiple first computing function modules are obtained, and the logical distances are used to reflect the time consumed by the computing function modules to process business requests.

Based on the logical distances of the multiple first computing function modules, at least one second computing function module is determined from the multiple first computing function modules, and the logical distance of the second computing function module is less than the preset distance threshold. The function registration information of the second computing function module is sent to the second network device. In this way, the relevant information of the computing function modules stored in the network device can be reduced, and the occupancy of storage resources is reduced. In addition, by sending a computing function module with a smaller logical distance to the second network device, the delay when the second network device assists in processing tasks through edge computing devices under other network devices can be reduced.

[0008] In one possible design, a function forwarding message sent by a third network device is received, and the function forwarding message includes: an initial logical distance and a number of jumps between each first computing function module and the third network device.

In the case where the third network device is a router, the initial logical distance is less than a preset distance threshold.

[0010] In one possible design, based on the initial logical distance and the number of jumps of each first computing function module, a first logical distance of each first computing function module is generated. A network quality parameter is obtained, and the network quality parameter is used to indicate the network quality between the first network device and the third network device. Based on the network quality parameter, a second logical distance is determined. Based on the first logical distance and the second logical distance, an updated logical distance of each first computing function module is generated.

[0011] In one possible design, a function call request sent by a fourth network device is received, and the function call request is used to request to call a target computing function module among multiple first computing function modules. Based on the function call request, a business processing request is sent to a target edge computing device where the target computing function module is deployed. The calculation result sent by the target edge computing device is received, and the calculation result is sent to the fourth network device.

[0012] In a possible design, the function registration information includes: an identifier of the computing function module and a uniform resource locator system of the computing function module.

[0013] In a second aspect, the present application provides a device for sharing a computing function module, the device comprising: an acquisition unit, a processing unit, and a sending unit.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The terms “first” and “second” in the description and claims of the present application are used to distinguish different objects rather than to describe a specific order of the objects.

[0031] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, but may optionally include other steps or modules that are not listed, or may optionally include other steps or modules that are inherent to these processes, methods, products or devices.

[0032] In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present concepts in a specific way.

[0033] With the vigorous development of new technologies such as cloud computing, big data, blockchain, and the Internet of Things, vehicle-road collaboration and autonomous driving, as the product of the combination of the traditional transportation industry and new technologies, have become an important support for smart transportation. The construction of smart highways is an important part of smart transportation, and "cloud-network-edge-end" has gradually become the new generation of smart highway technology architecture. In the new technology architecture, the role of "edge" has become more and more prominent, and the application scenarios have become more and more extensive.

[0034] In the smart intersection scenario of the transportation industry, edge computing devices can collect massive data from various sensing devices at the intersection, analyze and process the traffic conditions at the perceived intersection, including queue length, parking speed, travel speed, etc., and adjust the timing of traffic lights according to the degree of congestion, thereby improving the travel speed of urban traffic intersections.

[0035] Edge computing devices (such as roadside computing units) provide an edge computing service. Its edge computing architecture, in coordination with central computing resources, complements and optimizes central computing capabilities. It focuses on video perception and has rich perception capabilities such as target detection, attribute extraction, and event detection. It provides perception data services with relatively low latency and higher accuracy for the general perception needs of multiple categories of smart highways. It acquires real-time video to detect and analyze related events such as parking, congestion, and illegal lane changes, and outputs traffic parameters such as vehicle flow, average speed, time occupancy, space occupancy, headway, headway, and queue length. It realizes beyond-visual-range navigation based on digital twin capabilities, plays an important role in application scenarios such as autonomous driving, vehicle-road collaboration, and vehicle networking, and is widely used in intelligent traffic management in scenarios such as highways, viaducts, tunnels, and bridges. In traditional technologies, tasks with high latency requirements are mainly completed by the local computing power of edge computing devices, and tasks with low time requirements are transmitted back to the cloud for computing in a cloud-edge collaborative manner.

[0036] For example, Figure 1 As shown, the edge computing device 101 is connected to the perception device 102. For example, the edge computing device 101 may be a road side unit (RSU), and the perception device 102 may be a millimeter wave radar, a camera, etc. The perception device 102 may collect data from each vehicle. The edge computing device 101 may process the data. Alternatively, the edge computing device may transmit the data to the cloud control platform through the network, and the cloud control platform 103 may process the data.

[0037] However, the current construction method requires that the demand for computing power for low-latency computing tasks be planned according to road conditions at the beginning of construction, and a portion of computing power must be reserved, which increases the difficulty and cost of construction. In addition, if road facilities change after construction, the computing tasks may change, and the computing power of the edge computing equipment used before may not match the current road conditions, resulting in insufficient or wasted computing power. In addition, when short-term sudden traffic phenomena such as traffic jams and surrounding activities occur, the computing power will increase suddenly. If the computing power reserved during planning and construction is insufficient, the business processing capacity will be insufficient.

[0038] Therefore, how to improve the collaboration between edge computing devices and reduce resource usage during the collaboration process has become a technical problem that needs to be solved urgently.

[0039] In order to solve the above technical problems, an embodiment of the present application provides a method for sharing a computing function module. In this method, the logical distances of multiple first computing function modules are obtained, and the logical distances are used to reflect the time consumed by the computing function modules to process business requests. The multiple first computing function modules are deployed on at least one edge computing device. Based on the logical distances of the multiple first computing function modules, at least one second computing function module is determined from the multiple first computing function modules, and the logical distance of the second computing function module is less than the preset distance threshold. The function registration information of the second computing function module is sent to the second network device. In this way, the relevant information of the computing function modules stored in the network device can be reduced, and the occupancy of storage resources is reduced. In addition, by sending computing function modules with smaller logical distances to other network devices, the delay when other edge computing devices assist in processing tasks can be reduced.

[0040] The implementation environment of the embodiments of the present application is introduced below.

[0041] like Figure 2 As shown, a sharing system of a computing function module provided in an embodiment of the present application includes: multiple network devices 201 and multiple edge computing devices 202. The network devices 201 can be interconnected in a serial, tree, mesh, etc. manner, and the edge computing device 202 is mounted under the network device 201.

[0042] The network device 201 can manage the edge computing device 202. For example, the network device 201 can store the device information of the edge computing device 202. The network device 201 can also send the stored device information to other network devices. In addition, the network device 201 can receive the function call request of the edge computing device 202 and forward the function call request through other network devices 201 to complete the coordination between the edge computing devices.

[0043] Exemplarily, the network device 201 may be a router, a gateway (such as an NFaaS gateway), or other network devices.

[0044] The edge computing device 202 can process the computing task. The edge computing device can include at least one computing function module, which can process the computing task.

[0045] In one possible design, each network device 201 is connected to at least one edge computing device 202 .

[0046] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0047] like Figure 3 As shown, a method for sharing a computing function module provided in an embodiment of the present application includes:

[0048] S301. A first network device obtains logical distances of multiple first computing function modules.

[0049] The logical distance is used to reflect the time taken by the computing function module to process a business request, and multiple first computing function modules are deployed on at least one edge computing device.

[0050] It should be noted that the time taken by the computing function module to process a service request refers to the sum of the time taken by the computing function module to transmit the service request from the request end to the computing function module and the time taken by the computing function module to execute the computing task corresponding to the service request. The logical distance is proportional to the time taken by the computing function module to process the service request. The larger the logical distance, the longer the time taken by the computing function module to process the service request. The smaller the logical distance, the shorter the time taken by the computing function module to process the service request.

[0051] In one possible design, each edge computing device is deployed with at least one computing function module.

[0052] It should be noted that the computing function module refers to a module having computing functions, or having function computing services, or having a microservice application programming interface (Application Programming Interface, API), or having a dynamic function library. The present application embodiment does not limit the computing function module. For example, the computing function module can be a vehicle detection module, a pedestrian detection module, a license plate recognition module, etc.

[0053] In an embodiment of the present application, at least one edge computing device may be connected to a first network device. At least one edge computing device includes a first type of device and / or a second type of device. The first type of device is a network device directly connected to the first network device. The second type of device may be connected to the first network device through other network devices.

[0054] It should be noted that the first type of device being directly connected to the first network device means that the first device can directly send messages to the first network device. The second type of device being connected to the first network device through other network devices means that the second type of device can send messages to the first network device through other network devices.

[0055] Exemplarily, the first type device a can be configured with the address of gateway 1 and send a message to gateway 1. Alternatively, the first type device b can be directly connected to gateway 1, and the first type device b can broadcast a message. The second type device b is directly connected to gateway 2, and gateway 2 is connected to gateway 1, and the second type device b can be connected to gateway 1 through gateway 2.

[0056] In a possible implementation manner, the first network device stores logical distances of multiple first computing function modules, and the logical distance stored in the first network device is used to indicate the logical distance between the computing function module and the first network device.

[0057] It should be noted that the embodiment of the present application does not limit the logical distance. For example, the logical distance can be 1, 1.5, 3, 10, etc.

[0058] In some embodiments, the first network device may obtain status information and processing capabilities of multiple fifth computing function modules, and the status information is used to indicate whether other edge computing devices can call the computing function module. The status information includes available status information and unavailable status information, and the processing capability is used to indicate the ability to perform computing tasks. The first network device may determine multiple first computing function modules from multiple fifth computing function modules based on the status information and processing capabilities of the multiple fifth computing function modules.

[0059] S302: The first network device determines at least one second computing function module from the multiple first computing function modules based on the logical distances of the multiple first computing function modules.

[0060] Wherein, the logical distance of the second calculation function module is less than a preset distance threshold;

[0061] In a possible implementation, the logical distances of the plurality of first computing function modules are compared with a preset distance threshold, and then the first computing function module whose distance is less than the preset distance threshold is used as the second computing function module.

[0062] For example, if the plurality of first computing function modules include: computing function module a, computing function module b and computing function module c. The logical distance of computing function module a is 10, the logical distance of computing function module b is 2, and the logical distance of computing function module c is 1.5. If the preset distance threshold is 3, computing function module b and computing function module c can be used as the second computing function module.

[0063] S303. The first network device sends function registration information of at least one second computing function module to the second network device.

[0064] The function registration information may include at least one of the following: a logical distance, an identifier of a computing function module, and a uniform resource locator (URL) of the computing function module.

[0065] It should be noted that the embodiment of the present application does not limit the identifier of the computing function module. For example, the identifier of the computing function module can be a name, ID, etc.

[0066] In an embodiment of the present application, the first network device stores an identifier of a second network device connected to the first network device. The first network device can send function registration information of at least one second computing function module to the second network device based on the identifier of the second network device. The second network device is the next hop device of the first network device.

[0067] Exemplarily, the identifier of the second network device may be an iPv4 address, an ipv6 address, or the like.

[0068] In a possible implementation, the first network device may encapsulate the identifier, logical distance, and uniform resource locator system of each second computing function module into a first routing advertisement message, and send the first routing advertisement message to the second network device.

[0069] Based on the above technical solution, it can be known that the logical distances of multiple first computing function modules are obtained, and the logical distances are used to reflect the time consumed by the computing function modules to process business requests. Multiple first computing function modules are deployed on at least one edge computing device. Based on the logical distances of multiple first computing function modules, at least one second computing function module is determined from multiple first computing function modules, and the logical distance of the second computing function module is less than the preset distance threshold. The function registration information of the second computing function module is sent to the second network device. In this way, the relevant information of the computing function modules stored in the network device can be reduced, and the occupancy of storage resources is reduced. In addition, by sending a computing function module with a smaller logical distance to the second network device, the delay when the second network device assists in processing tasks through edge computing devices under other network devices can be reduced.

[0070] like Figure 4 As shown, a method for sharing a computing function module provided in an embodiment of the present application, in which S302 may include:

[0071] S401. A first network device receives a function forwarding message sent by a third network device.

[0072] The function forwarding message includes: the initial logical distance and the number of jumps between each first computing function module and the third network device. The initial logical distance refers to the logical distance between the first computing function module and the third network device, and the number of jumps refers to the number of jumps required for the message to jump from the source node to the destination node along the route.

[0073] For example, if network device a is directly connected to network device b, the number of jumps in the function forwarding message sent by network device a to network device b is 1.

[0074] It should be noted that, usually, the number of jumps is 1.

[0075] In an embodiment of the present application, the third network device may include: a router and / or an edge computing device. The plurality of first computing function modules include: at least one third computing function module and / or at least one fourth computing function module. The initial logical distance of the third computing function module is stored in the router, and the fourth computing function module is deployed in the edge computing device.

[0076] In some embodiments, when the third network device is a router, the third network device is the previous hop device of the first network device, and the function forwarding message is a routing announcement message. The third network device can send a second routing announcement message to the first network device, and the second routing announcement message includes function registration information and the number of jumps of at least one third computing function module. Wherein, when the third network device is a router, the initial logical distance is less than the preset distance threshold.

[0077] It is understandable that when the third network device is a router, the third network device can selectively select computing function modules with initial logical distances less than a preset distance threshold to share with the first network device, thereby reducing the time spent by the first network device in calling the computing function module through the third network device.

[0078] In some embodiments, when the third network device includes an edge computing device, the function forwarding message is a function registration message, and the initial logical distance is 0. That is, the edge computing device is a device mounted under the first network device. The third network device can send a function registration message to the first network device, and the function registration message includes function registration information of at least one fourth computing function module.

[0079] In some embodiments, after the first network device receives the function forwarding message sent by the third network device, the function registration information may be stored in the routing table.

[0080] Exemplarily, as shown in Table 1, it shows the routing table stored in the first network device.

[0081] Table 1

[0082] name Logical distance Next hop network device Computing function module 1 3 The address of network device a Computational function module 2 2 The address of network device b Computational function module 3 2.5 The address of network device b

[0083] Among them, the next-hop network device refers to the next-hop device of the first network device in the route when accessing the computing function module. That is, the logical distance between computing function module 1 and the first network device is 3, and calling computing function module 1 requires forwarding the request to network device a. The logical distance between computing function module 2 and the first network device is 2, and calling computing function module 2 requires forwarding the request to network device b. The logical distance between computing function module 3 and the first network device is 2.5, and calling computing function module 3 requires forwarding the request to network device b.

[0084] Exemplarily, the address of the network device may be an IPv4 address, an IPv6 address, or the like.

[0085] In some embodiments, the first network device may also update stored function registration information of each computing function module.

[0086] Exemplarily, the function registration information of each computing function module may be added, modified, or deleted.

[0087] S402: The first network device generates an updated logical distance of each first computing function module based on the initial logical distance and the number of jumps of each first computing function module.

[0088] The updated logical distance is used to indicate the logical distance to the first network device.

[0089] In a possible implementation, the first network device may obtain a target distance increment based on the number of jumps and a preset distance increment, where the preset distance increment is used to indicate the logical distance increased by one jump. Afterwards, the first network device generates an updated logical distance for each first computing function module based on the sum of the initial logical distance of each first computing function module and the target distance increment.

[0090] For example, if the jump count is 1, the preset distance increment is 1, and the initial logical distance is 0, the updated logical distance is 1. If the jump count is 1, the preset distance increment is 1, and the initial logical distance is 2, the updated logical distance is 3.

[0091] It is understandable that after the first network device receives the function forwarding message sent by the third network device, it can generate the updated logical distance of each first computing function module based on the initial logical distance and the number of jumps. In this way, it is convenient for the first network device to select the computing function module for assistance according to the latest logical distance, thereby improving the accuracy of the selection.

[0092] like Figure 5 As shown, a method for sharing a computing function module provided in an embodiment of the present application, in which S402 may include:

[0093] S501. The first network device generates a first logical distance for each first computing function module based on an initial logical distance and a jump count of each first computing function module.

[0094] It should be noted that the process of generating the first logical distance may refer to the description of generating the updated logical distance in S402 in the above embodiment, which will not be described in detail here.

[0095] S502: The first network device obtains a network quality parameter.

[0096] The network quality parameter is used to indicate the network quality between the first network device and the third network device. The network quality parameter may include at least one of the following parameters: delay, delay jitter, packet loss rate, bandwidth, etc.

[0097] S503: The first network device determines a second logical distance based on the network quality parameter.

[0098] In a possible implementation manner, the second logical distance is determined based on each parameter and a weight corresponding to the parameter.

[0099] For example, if the delay jitter, packet loss rate, and bandwidth are x1, x2, and x3 respectively, the corresponding weight coefficients are a1, a2, and a3 respectively. The second logical distance value is Y=a1*x1+a2*x2+a3*x3.

[0100] S504: The first network device generates an updated logical distance for each first calculation function module based on the first logical distance and the second logical distance.

[0101] In the embodiment of the present application, the updated logical distance is the sum of the first logical distance and the second logical distance.

[0102] Exemplarily, if the first logical distance is 1 and the second logical distance is 2.5, the updated logical distance is 3.5.

[0103] It can be understood that, based on the initial logical distance and the number of jumps of each first computing function module, the first logical distance of each first computing function module is generated. After that, the network quality parameter is obtained, and the second logical distance is determined based on the network quality parameter. Then, based on the first logical distance and the second logical distance, the updated logical distance of each first computing function module is generated. In other words, the updated logical distance takes into account the number of jumps and the network quality. In this way, the time spent by the computing function module to process the service request can be more truly reflected.

[0104] In some embodiments, the first network device may receive a function call request sent by the fourth network device, and the function call request is used to request to call a target computing function module among multiple first computing function modules. Afterwards, the first network device may send a business processing request to the target edge computing device where the target computing function module is deployed based on the function call request, and the business processing request is used to instruct to calculate the target computing task. Then, the target edge interpretation device may call the target edge computing device to calculate the target computing task in response to the business processing request to obtain a calculation result. Afterwards, the target edge computing device may send the calculation result to the first network device, and the first network device may send the calculation result to the fourth network device.

[0105] It is understandable that after receiving the function call request sent by the fourth network device, the first network device can call the mounted target edge computing module to assist in completing the computing task. In this way, each edge computing device can assist each other, thereby improving resource utilization.

[0106] The following is an introduction to the embodiments of the present application with reference to specific examples. Figure 6As shown, gateway 1 is connected to edge computing device 1, and gateway 2 is connected to edge computing device 2. Gateway 1 and gateway 2 both include: a function registration module, a function routing table, an information notification module, and a routing forwarding module. The function registration module is used to obtain the function registration information of the computing function module in the mounted edge computing device, and store the function registration information in the function routing table. The information passing module is used to transmit the function registration information of each computing function module with other network devices (such as gateways), and update the function registration information in other network devices to the function routing table. The routing forwarding module is used to forward function call requests and calculation results. Edge computing device 1 and edge computing device 2 both include at least one computing function module and a function publishing module.

[0107] For example, the edge computing device 1 includes a vehicle detection module and a pedestrian detection module. The edge computing device 1 can send a function registration message to the gateway 1 through the function publishing module. The function registration module of the gateway 1 can add the function registration information of the vehicle detection module and the function registration information of the pedestrian detection module to the function routing table. In addition, the information notification module can send the function registration information stored in the function routing table of the gateway 1 to the gateway 2.

[0108] For another example, the edge computing device 2 also includes a remote call proxy module. The business application in the edge computing device 2 can send a call request to the remote call proxy module, and the remote call proxy module sends a function call request to the gateway 2.
