A computing network (also referred to as a computing power network) refers to a technology that flexibly schedules computing resources among cloud computing nodes, network nodes, and edge cloud computing nodes according to computing demands of computing tasks, and stores resources and network resources to complete computation of the computing tasks.
Current computing networks mainly include: the control plane calculates the network cooperation and dispatches, the data plane network fusion perceives, manages and serves the calculation resource arrangement of the plane, etc. The computing network can uniformly and coordinately manage the computing resources, the storage resources and the network resources, and can measure the computing resources, the storage resources and the network resources according to uniform standards. In a computing network, the computing resources, storage resources and network resources of each node may be represented in specific parameter forms, where these parameters may be carried in data packets transmitted between nodes to inform other nodes of their own resource conditions. Current computing networks also typically add the ability to provide user-oriented intuitive components and services; through the communication between the service layer and the underlying resource and network interface, the visualization in arrangement, scheduling and application is realized.
An example is shown in fig. 2, which is a network architecture diagram of an edge computing network 20 provided in the present application. As shown in fig. 2, in the edge computing network, it includes: a plurality of edge computing nodes 201, a plurality of network devices 202, a computing network management system 203, and user devices 204.
The user equipment 204 is accessed into the edge computing node 201, and sends the computing task to the edge computing node 201.
The edge computing node 201 is configured to receive a computing task from a user device, deploy the computing task, calculate the computing task, and return a calculation result to the user device. The edge computing node 201 is connected to a network device 202. The edge computing nodes 201 may communicate with each other via a network device. In addition, the edge computing node 201 may also communicate with the computing network management system 203 via network devices

In the mobile edge computing scene, user equipment is accessed into an edge computing node, and the edge computing node provides computing service for users. However, in the scenario where the user equipment is moving continuously, if the user equipment moves to a position far away from the edge computing node, the quality of service of the edge computing node for providing computing service to the user will be reduced. Existing schemes typically switch user equipment from a primary edge force node (denoted as a first edge force node) to a closer edge force node (denoted as a second edge force node). The computing power service of the user equipment is still processed on the first edge computing power node, and the second edge computing power node serves as a transit to forward the processing result and the task to be processed. However, this method increases the delay of processing the computing power service by the edge node, and reduces the quality of the computing power service provided by the edge computing power node.
In order to solve the problems in the prior art, the present application provides a power calculation service switching method, which can determine whether a power calculation service is provided for user equipment by a second edge power calculation node by determining whether the second edge power calculation node supports a first power calculation service provided for the user equipment by the first edge power calculation node and whether a service delay of the second edge power calculation node is smaller than a service delay of the first edge power calculation node under a condition that the user equipment is close to the second edge power calculation node. Therefore, when the second edge computing node supports the first computing service and the service time delay is smaller than that of the first edge computing node, the second edge computing node continuously provides network access service and the first computing service for the user equipment, so that the user equipment is switched to the second edge computing node, the time delay of the edge computing node for processing the computing service is further reduced, and the quality of the computing service provided by the edge computing node to the user is improved.
The power calculation service switching scheme provided by the embodiment of the application can be applied to the electronic equipment shown in the figure 1. The electronic device according to the embodiment of the present application may be an edge computing node shown in fig. 2, or a computing network management system, or may be a newly added independent device, which is not limited in this application.
The method and the device solve the problem that the user equipment cannot be effectively switched when the user equipment is provided with the power calculation service in the prior art. As shown in fig. 3, the method for switching the computing power service provided by the application includes the following steps:
s301, the electronic device receives first indication information from a first edge computing node.
In one possible implementation, the electronic device is illustrated as a second edge computing node.
The first indication information is used for indicating the second edge computing node to judge whether the second edge computing node supports the first computing service or not, and the first edge computing node is the edge computing node for providing the first computing service for the user equipment.
Optionally, when the distance between the user equipment and the second edge computing node is smaller than or equal to the preset distance, the second edge computing node sends first request information to the first edge computing node, and the first request information is used for indicating the first edge computing node to send first indication information to the second edge computing node.
After that, the first edge computing node feeds back the first indication information to the second edge computing node according to the received first request information.
It should be noted that, in practical application, the preset distance may be set by manual implementation, which is not limited in the embodiment of the present application.
S302, the electronic device judges whether the second edge computing node supports the first computing service.
Optionally, determining whether the second edge computing node supports the first computing service may be specifically classified into the following four cases:
the first and second edge computing nodes have non-network reasons for not supporting the first computing service.
Among other non-network reasons that do not support the first computing service may include: hardware unsupported, manual preset rule restrictions, etc.
In this case, the electronic device determines that the second edge computing node does not support the first computing service.
And in the second case, the second edge computing node does not have a non-network reason for not supporting the first computing service, and the computing service operated by the second edge computing node comprises the first computing service.
In this case, the electronic device determines that the second edge computing node supports the first computing service.
And in the third case, the second edge computing node does not have a non-network reason for not supporting the first computing service, the computing service operated by the second edge computing node does not comprise the first computing service, but the second edge computing node has enough resources for deploying the first computing service.
In this case, the electronic device determines that the second edge computing node supports the first computing service.
It should be noted that the existence of sufficient resources at the second edge computing node may include: (1) And the second edge computing power node has idle resources which can meet the requirement of deploying the first computing power service. (2) The second edge computing node does not have idle resources, but idle computing services exist, and after the second edge computing node suspends the idle computing services, the released resources can meet the requirement of deploying the first computing services.
And in the fourth case, the second edge computing node does not have a non-network reason for not supporting the first computing service, the computing service operated by the second edge computing node does not comprise the first computing service, and the second edge computing node does not have enough resources for deploying the first computing service.
In this case, the electronic device determines that the second edge computing node does not support the first computing service.
Optionally, in case the electronic device determines that the second edge computing node supports the first computing service, a subsequent step S303 is performed.
S303, the electronic equipment determines the service time delay of the first edge computing node and the service time delay of the second edge computing node.
Optionally, the first indication information received by the electronic device includes service status information of the first computing service. Further, the service state information includes a service delay of the first edge computing node.
In one possible implementation, the service state information of the first computing service is carried in a user snapshot of the first computing service that includes all of the service states of the first computing service (including, but not limited to, the service delays of the first computing service). Specifically, after receiving a first service request of a second edge service node, the first edge service node performs a snapshot on a current state of user service of the first service, and loads snapshot information in first indication information to send the snapshot information to the second edge service node.
It can be appreciated that the first edge computing node may also send the user snapshot of the first computing service to the second edge computing node alone, without being carried in the first indication information.
It should be noted that, the service delay T of an edge computing node for a computing service is specifically composed of a wireless channel delay T1 and a wired channel delay T2, i.e., t=t1+t2. The wireless channel delay T1 is the delay of wireless communication between the user equipment and the edge computing node, and a method for specifically obtaining the delay is the prior art, which is not described herein.
Illustratively, in each edge computing node, an edge computing node service delay table is maintained, and the table is dynamically updated, specifically, the cable channel delay of the current edge computing node and each other edge computing node in the computing network can be reflected for a certain computing service. For example, table 1 below shows specific data of service delays of a certain edge computing node with other edge computing nodes:
Table 1 service delay table of edge computing node
| Computing force service ID | Wired channel delay T2 (ms) | Service delay object node |
| c0018764 | 90 | N1 |
| c00872655 | 66 | N7 |
| c0044875 | 0 | L |
Note that in table 1, N1 and N7 represent other edge computing nodes, and L represents the edge computing node itself (i.e., the time delay between the edge computing node and itself is 0).
It will be appreciated that by way of the above example, each edge computing node in the computing network is able to determine its own wireless channel delay T1 and wired channel delay T2, and thus its own service delay.
It should be noted that, if a certain edge computing node supports the first computing service, the service delay of the edge computing node is the wireless channel delay of the edge computing node at this time.
Through the above example, the electronic device can obtain and compare the service delays of the first edge computing node and the second edge computing node. If the service delay of the second edge computing node is smaller than the service delay of the first edge computing node, the following step S304 is executed.
S304, the electronic equipment provides network access service and the first computing power service for the user equipment.
In one possible implementation, the electronic device is illustrated as a second edge computing node. Correspondingly, at the moment, the user equipment is switched to a second edge computing node, and the second edge computing node is the user equipment.
Optionally, corresponding to the example in step S303, the first indication information received by the second edge computing node includes a user snapshot of the first computing service, and the second edge computing node can copy the user state to the local according to the user snapshot, so that the user equipment is seamlessly switched to the second edge computing node to use the first computing service.
Based on the above technical solution, in the case that the user equipment is close to the second edge computing node, the embodiment of the present application determines whether the second edge computing node provides computing service for the user equipment by determining whether the second edge computing node supports the first computing service provided by the first edge computing node for the user equipment, and whether the service delay of the second edge computing node is smaller than the service delay of the first edge computing node. Therefore, when the second edge computing node supports the first computing service and the service time delay is smaller than that of the first edge computing node, the second edge computing node continuously provides network access service and the first computing service for the user equipment, so that the user equipment is switched to the second edge computing node, the time delay of the edge computing node for processing the computing service is further reduced, and the quality of the computing service provided by the edge computing node to the user is improved.
Referring to fig. 3, as shown in fig. 4, in the case that the service delay of the second edge computing node is greater than or equal to the service delay of the first edge computing node, the computing power service switching method further includes the following steps:
s401, the electronic equipment keeps the first edge computing power node to provide the first computing power service for the user equipment.
In one possible implementation, the electronic device is illustrated as a second edge computing node.
It may be appreciated that in this case it is shown that although the second edge computing node supports the first computing service, the second edge computing node is not required to switch the user equipment, and the first edge computing node is required to maintain the computing service with the user equipment, since the service delay of the second edge computing node is greater than or equal to the service delay of the first edge computing node.
Referring to fig. 3, as shown in fig. 5, in a case where the second edge computing node does not support the first computing service, the computing service switching method provided by the application further includes the following steps:
s501, the electronic equipment judges whether the service time delay of the second edge computing node is smaller than that of the first edge computing node.
In one possible implementation, the electronic device is illustrated as a second edge computing node.
Optionally, if the service delay of the second edge computing node is greater than or equal to the service delay of the first edge computing node, the following step S502 is executed.
Optionally, if the second edge computing node does not support the first computing service and the service delay of the second edge computing node is smaller than the service delay of the first edge computing node, the following step S503 is executed.
S502, the electronic device keeps the first edge computing node to provide a first computing service for the user device.
In one possible implementation, the electronic device is illustrated as a second edge computing node.
It can be understood that in this case, it is indicated that the second edge computing node does not support the first computing service, and the service delay is also greater than or equal to the service delay of the first edge computing node, so that the user equipment does not need to be switched, and the first edge computing node can keep the computing service with the user equipment.
S503, the electronic equipment provides network access service for the user equipment and sends a user snapshot of the first computing service to the third edge computing node.
In one possible implementation, the electronic device is illustrated as a second edge computing node.
The third edge computing node is the edge computing node with the smallest communication time delay with the second edge computing node in the edge computing nodes supporting the first computing service. The method for determining the service delay of the third edge computing node and the method for determining whether to support the first computing service are the same as those described in the foregoing step S303, and will not be described herein again.
It should be noted that, at this time, although the second edge computing node does not support the first computing service, since the service delay of the second edge computing node is minimum, the second edge computing node provides the network access service for the user equipment, and the second edge computing node relays the service data of the first computing service of the third edge computing node, and forwards the service data of the first computing service to the user equipment, so that the delay when the edge computing node provides the computing service for the user is minimum.
It is understood that in the case where the service delay of the first edge computing node is the minimum, the third edge computing node at this time is the same node as the first edge computing node. Accordingly, the user equipment need not handover the node for the first computing power service.
Optionally, the second edge computing node sends the user snapshot of the first computing service to the third edge computing node, so that the third edge computing node obtains the data of the user equipment, and the user equipment is seamlessly switched to the third edge computing node to use the first computing service.
The power calculation service switching method provided by the application is specifically described above.
The switching flow of the computing service is illustrated below with reference to a specific example.
As shown in fig. 6, the computing network includes nine edge computing nodes N1-N9, the user equipment initial access node is N1, and the user equipment moves from N1 to N7. The following description is made in connection with three kinds of scenes (scene a, scene B, and scene C):
(1) For scenario a, the power network satisfies the following condition:
condition one, edge computing nodes N1, N7 support computing service c00872655, and N9 supports computing service c00872655.
The wireless communication delays between the second condition, N1, N9 and N7 and the user equipment are respectively 50ms, 20ms and 90ms.
The third condition is that for the computing service c00872655, the wired channel communication delay between N1 and N9 is 20ms, and the wired channel communication delay between N7 and N9 is 10ms.
Condition four, consider temporarily other nodes than N1, N7, N9.
In scenario a, since N9 supports the computing service c00872655, the service delays of N1, N7, N9 are readily available at this time as:
the service delay of N1 is: t (T) N1 ＝50ms；
The service delay of N7 is: t (T) N7 ＝90ms；
The service delay of N9 is: t (T) N9 ＝20ms。
Due to T N9 ＜T N1 ＜T N7 The user equipment is thus handed over to N9, and the network access service and the computing service c00872655 continue to be provided to the user equipment by N9.
(2) For scenario B, the power network satisfies the following condition:
condition one, edge computing node N1, N7 supports computing service c00872655, and N9 does not support computing service c00872655.
The wireless communication delays between the second condition, N1, N9 and N7 and the user equipment are respectively 50ms, 20ms and 90ms.
The third condition is that for the computing service c00872655, the wired channel communication delay between N1 and N9 is 20ms, and the wired channel communication delay between N7 and N9 is 10ms.
Condition four, consider temporarily other nodes than N1, N7, N9.
In scenario B, since N9 does not support the computing service c00872655, the service delays of N1, N7, N9 are readily available at this time as:
the service delay of N1 is: t (T) N1 ＝50ms；
The service delay of N7 is: t (T) N7 ＝90ms；
The service delay of N9 is: t (T) N9 ＝20ms+10ms＝30ms。
Due to T N9 ＜T N1 ＜T N7 The network access service is thus provided by N9 for the user equipment, i.e. the user equipment is now accessing N9, but the power service c00872655 is provided by N7, N9 only acting as a network access node and as a data forwarding node for the power service c00872655.
(3) For scenario C, the power network satisfies the following condition:
condition one, edge computing nodes N7, N8 support computing service c00872655, and N9 does not support computing service c00872655.
And under the second condition, the user equipment continues to move, network access is stopped with the N1, and wireless communication time delays of the N7, the N8 and the N9 with the user equipment are respectively 70ms, 20ms and 25ms.
For the third condition, the communication delay of the wired channel between N1 and N9 is 20ms, the communication delay of the wired channel between N7 and N9 is 10ms, and the communication delay of the wired channel between N8 and N9 is 5ms for the computing service c00872655.
Condition four, consider nodes other than N1, N7, N8, N9 temporarily.
In scenario C, since N9 does not support the computing service C00872655, the service delays of N1, N7, N8, N9 are readily available at this time as:
the service delay of N7 is: t (T) N7 ＝70ms；
The service delay of N8 is: t (T) N8 ＝20ms；
The service delay of N9 is: t (T) N9 ＝25ms+5ms＝30ms。
Due to T N8 ＜T N9 ＜T N7 The user equipment is switched to N8, and the network access service and the computing power service c00872655 are continuously provided for the user equipment by the N8.
