Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Currently, the service allocation method of each edge server to client nodes and low-cost nodes is often selectively regulated based on the bandwidth usage of each edge server node. However, since the edge server node is a device that directly communicates with third-party service nodes, the edge server The stability of its own work will directly affect the normal acquisition of data streams by client nodes and low-cost nodes, and it is difficult to ensure the overall efficiency and stability of the process of acquiring data streams through client nodes in a shared computing scenario.

The core of the present invention is to provide a server allocation method, so as to relatively improve the comprehensiveness of the reference factors when the edge server is allocated, so as to further ensure the overall efficiency and stability of the data service provided by the edge server. Another core of the present invention is to provide a server distribution device, system and medium.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

FIG. 2 is a flowchart of a server allocation method according to an embodiment of the present invention. Please refer to FIG. 2, the specific steps of the server allocation method include:

Step S10: Obtain network parameters and hardware parameters of the edge server, and obtain service feedback indicators of the edge server transmitted by the low-cost node and the client node.

It should be noted that the allocation control node first obtains the network parameters and hardware parameters of the edge server, where the network parameters refer to the relevant working status data involved in the network data communication between the edge server and external devices, and the hardware parameters refer to It is the relevant working status data generated by the edge server occupying hardware resources when it performs network data communication with external devices or performs data processing tasks by itself. The execution subject of the method is the distribution control node, that is to say, the distribution control node can perform data communication with the edge server, and then can obtain the network parameters and hardware parameters of the edge server.

In addition, it should be noted that this method is a technical solution based on a shared computing scenario. In the shared computing scenario, the edge server node directly pulls the data stream from the third-party service node, and then can provide the pulled data stream to For low-cost nodes or client nodes, where low-cost nodes refer to node devices established between client nodes and edge servers, for example, in practical applications, low-cost nodes can be specifically NAS devices, because NAS devices can When accessing and acquiring the data stream in the edge server, the client node can indirectly acquire the data stream in the edge server through the NAS device, or the client node can directly access the edge server and acquire the data stream in the edge server.

Step S11: Selectively assign the access rights of the edge server to the low-cost nodes and/or client nodes according to the preset conditions satisfied by the network parameters, hardware parameters and service feedback indicators.

It should be noted that the focus of this step is to assign the control node to comprehensively analyze the network parameters and hardware parameters of the edge server, and then selectively assign the access rights of the edge server according to the preset conditions satisfied by the network parameters and hardware parameters. Assigned to low-cost nodes and/or client nodes. It should be emphasized that the focus of this embodiment is to comprehensively analyze the network parameters and hardware parameters. Based on the analysis of the network parameters, it is considered that when the edge server consumes network resources to provide services to external devices, it will simultaneously Occupying hardware resources, this step uses the current network parameters and hardware parameters of the edge server as the basis for allocating edge servers to low-cost nodes and client nodes when allocating edge servers, which relatively improves the allocation of edge servers. comprehensiveness of the factors considered.

The server allocation method provided by the present invention first obtains the network parameters and hardware parameters of the edge server, and obtains the service feedback index of the edge server transmitted by the low-cost node and the client node, and then obtains the service feedback index, network parameters and hardware parameters according to the service feedback index, network parameters and hardware parameters. The preset conditions met by the parameters selectively allocate the access rights of the edge server to low-cost nodes and/or client nodes. Considering that when the edge server provides data to low-cost nodes and/or client nodes, it will occupy the hardware resources of the edge server, which will affect its own work stability. Therefore, this method uses the network parameters of the edge server to , hardware parameters, and the service status of edge servers at low-cost nodes and client nodes serve as constraints for allocating edge server allocation methods, and then selectively assign edge servers to low-cost nodes and/or client nodes for use. In order to provide low-cost nodes and/or client nodes with data streams of third-party service nodes, this method relatively improves the comprehensiveness of the reference factors when allocating edge servers, thereby further ensuring the overall integrity of edge servers providing data services. efficiency and stability.

On the basis of the foregoing embodiment, as a preferred implementation manner, the network parameters include bandwidth usage;

Correspondingly, before selectively allocating the access rights of the edge server to low-cost nodes and/or client nodes according to the preset conditions satisfied by network parameters, hardware parameters and service feedback indicators, the method further includes:

On the premise that the service feedback index satisfies the index condition, determine whether the bandwidth usage rate is less than the bandwidth warning threshold;

If yes, execute the step of selectively allocating the access rights of the edge server to the low-cost nodes and/or client nodes according to the preset conditions satisfied by the network parameters, hardware parameters and service feedback indicators.

It should be noted that the focus of this embodiment is to first determine whether the bandwidth usage rate of the edge server is less than the bandwidth warning threshold, so as to determine whether to allocate the access right of the edge server. The purpose of the bandwidth warning threshold is to define whether the bandwidth of the current edge server is in a high-occupancy warning state. The specific value of the bandwidth warning threshold should be determined according to the actual network communication performance of the edge server, which is not specifically limited here. This embodiment relatively improves the overall reliability of server allocation.

On the basis of the above embodiments, the present invention also provides the following series of preferred embodiments.

FIG. 3 is a flowchart of another server allocation method provided by an embodiment of the present invention. Please refer to FIG. 3, the specific steps of the server allocation method include:

Step S20: Obtain network parameters and hardware parameters of the edge server including bandwidth usage, and obtain service feedback indicators of the edge server transmitted by the low-cost node and the client node.

In this embodiment, the network parameters obtained from the edge server should include at least the bandwidth usage rate, and the bandwidth represents the data transmission capability during signal transmission, that is, the amount of data passing through the link per unit time. Link resources are often limited, so the total amount of bandwidth is also certain. The bandwidth usage rate represents the degree to which the overall bandwidth of the edge server is occupied. In addition, the higher the bandwidth usage rate, the lower the reliability of the network status of the edge server, that is, the lower the ability of the edge server to transmit data with external devices.

Step S21: When the value of the bandwidth usage rate is less than the minimum bandwidth threshold, the value of the hardware parameter is less than the hardware warning threshold, and the service feedback index meets the index condition, assign the access right of the edge server to the low-cost node and the client node at the same time.

The minimum bandwidth threshold is smaller than the bandwidth warning threshold.

Based on the above explanation of bandwidth usage, when the value of bandwidth usage is less than the minimum bandwidth threshold, it means that the current bandwidth usage of the edge server is relatively low, and the edge server has high network communication performance. In this case, when When the value of the hardware parameter of the edge server is less than the hardware warning threshold, that is, the hardware resource occupation of the edge server itself is relatively small, and the edge server has high data processing performance. When the bandwidth of the edge server and the occupied degree of hardware are both small, it means that the edge server has relatively sufficient network resources and hardware resources. Therefore, in this case, the access rights of the edge server are allocated to the low-cost nodes and the client nodes at the same time, so that the This can relatively ensure that the overall resources of the edge server are effectively utilized.

Step S22: When the value of the bandwidth usage rate is greater than or equal to the minimum bandwidth threshold and less than the free allocation threshold, the value of the hardware parameter is less than the hardware warning threshold, and the service feedback indicator satisfies the indicator condition, determine whether there is a device with a communication cost lower than the edge server and For the preferred edge server whose working status is consistent with that of the edge server, if yes, go to step S23; otherwise, go to step S24.

Step S23: Allocate the access right of the preferred edge server to the low-cost node and the client node at the same time.

Step S24: Allocate the access right of the edge server to the low-cost node and the client node at the same time.

Among them, the free allocation threshold is smaller than the bandwidth warning threshold.

It should be noted that when the value of the bandwidth usage rate reaches or exceeds the range of the minimum bandwidth threshold, that is, it is greater than or equal to the minimum bandwidth threshold and less than the free allocation threshold, and the value of the hardware parameter is less than the hardware warning threshold, it means that the edge server is currently The occupied degree of the hardware is relatively small, and the bandwidth has been occupied to a certain extent but has not reached a high degree of occupancy. In this case, this embodiment determines whether to use the edge server to low-cost nodes according to the communication cost of the edge server. Provide data services with client nodes, that is, determine whether there is a preferred edge server with a device communication cost lower than that of the edge server and the same working state as the edge server. When the bandwidth usage value of the preferred edge server is also greater than or equal to the minimum bandwidth threshold and less than the free allocation threshold, the value of the hardware parameter is less than the hardware alert threshold, and the device communication cost is lower than the preferred edge server of the edge server, the preferred edge server will be selected. On the contrary, if the above-mentioned preferred edge server does not exist, the access rights of the edge server are allocated to the low-cost node and the client node at the same time, which relatively reduces the network The overall cost of data services provided by edge servers under the system.

Step S25: On the premise that the service feedback index satisfies the index condition, when the value of the bandwidth usage rate is greater than or equal to the free allocation threshold and less than the bandwidth warning threshold, or when the value of the hardware parameter is greater than the hardware warning threshold, the access right of the edge server is only Allocate to low-cost nodes.

It should be noted that when the value of the bandwidth usage rate is greater than or equal to the free allocation threshold and less than the bandwidth warning threshold, it means that the current network resource occupancy for the edge server is close to the warning situation; when the value of the hardware parameter is greater than the hardware warning threshold , indicating that the hardware resources of the edge server are relatively occupied. In order to relatively ensure that the limited resources of the edge server can serve more client nodes, when either of the above two conditions is satisfied, this embodiment allocates the access right of the edge server only to low-cost nodes. Nodes can still indirectly access data streams in edge servers through low-cost nodes. Therefore, after allocating the access rights of edge servers to low-cost nodes, data streams can be provided to client nodes through low-cost nodes. While the limited resources can serve more client nodes, it relatively avoids the client nodes from further occupying the available resources of the edge server.

Step S26: On the premise that the service feedback index satisfies the index condition, when the bandwidth usage rate reaches the bandwidth exhaustion threshold, or the value of the hardware parameter reaches the hardware exhaustion threshold, stop allocating the access right of the edge server to the low-cost nodes and customers end node.

The bandwidth exhaustion threshold is greater than the bandwidth warning threshold, and the hardware exhaustion threshold is greater than the hardware warning threshold.

It should be noted that, when the bandwidth usage rate reaches the bandwidth exhaustion threshold, or the value of the hardware parameter reaches the hardware exhaustion threshold, in order to prevent the edge server from overrunning and downtime, which may affect the stability of the edge server, this embodiment Stop assigning edge server access to low-cost nodes and client nodes.

In addition, it should be emphasized that this embodiment adopts the minimum bandwidth threshold, the free allocation threshold, the bandwidth warning threshold and the bandwidth exhaustion threshold respectively in determining the bandwidth usage rate of the network parameters. The relationship is: bandwidth minimum threshold < free allocation threshold < bandwidth warning threshold < bandwidth exhaustion threshold. Since the above thresholds measure the degree of bandwidth utilization, the specific value should be determined according to the actual situation, such as the minimum bandwidth threshold is 20%, the free allocation threshold is 85%, the bandwidth warning threshold is 90%, and the bandwidth exhaustion threshold is 95%; the hardware parameters are determined based on the hardware warning threshold and the hardware exhaustion threshold, and the relationship between the two is: hardware warning threshold <Hardware exhaustion threshold, in this technology, since hardware parameters can be further refined, there should be corresponding hardware warning thresholds and hardware exhaustion thresholds for each specific hardware parameter.

In the technical aspect of the foregoing embodiment, as a preferred implementation manner, the hardware parameters include the CPU usage rate and the memory usage rate.

Since the CPU and memory are important hardware factors that restrict the data processing efficiency of the edge server, the hardware parameters in this embodiment include the CPU usage rate and the memory usage rate, so that the edge server can be relatively accurately improved based on the CPU usage rate and the memory usage rate. allocation accuracy.

In a specific application scenario, the hardware warning thresholds of CPU usage and memory usage may be 85%, respectively, and the hardware exhaustion thresholds may be 95%, respectively.

As a preferred embodiment, the service feedback indicators include connection success rate and response delay;

Correspondingly, the service feedback indicator satisfies the indicator conditions, including:

When the connection success rate is greater than the preset success rate threshold and/or the response delay is greater than the preset delay threshold.

It should be noted that the network parameters in this embodiment include the connection success rate and the response delay. The connection success rate represents that when the edge server responds to the access of the low-cost node or client node, the low-cost node or client normally accesses the edge. The probability of the server, and the response delay represents the time taken by the edge server to respond to the low-cost node or client node after the low-cost node or client node accesses the edge server. When the connection success rate is greater than the preset success rate threshold, or the response delay is greater than the preset delay threshold, it indicates that the edge server provides data services with high reliability and efficiency. The premise of nodes and client nodes can relatively guarantee the service efficiency and reliability for low-cost nodes and client nodes.

As a preferred embodiment, before selectively allocating the access rights of the edge server to low-cost nodes and/or client nodes according to network parameters, hardware parameters and preset conditions satisfied by service feedback indicators, the method further includes:

Get the number of client nodes that the edge server has connected to;

Correspondingly, according to the preset conditions satisfied by network parameters, hardware parameters and service feedback indicators, the access rights of edge servers are selectively allocated to low-cost nodes and/or client nodes, including:

When the number of client nodes is less than the preset access threshold, the access rights of the edge server are selectively allocated to low-cost nodes and/or client nodes according to network parameters, hardware parameters, and preset conditions satisfied by service feedback indicators.

It should be noted that the focus of this embodiment is to obtain the number of client nodes of the client nodes that have been connected to the edge server, and to analyze the number of client nodes of the client nodes that have been connected to the edge server. When setting the access threshold, according to the preset conditions met by network parameters and hardware parameters, the access rights of edge servers are selectively allocated to low-cost nodes and/or client nodes, that is, the access rights of edge servers are selectively allocated. This operation allocated to low-cost nodes and/or client nodes needs to be performed based on the number of client nodes of the edge server being less than the preset access threshold. This embodiment relatively ensures that the number of nodes accessing the edge server is within a controllable range, reduces the overall occupation of resources in the edge server to a certain extent, and ensures the working stability of the edge server.

Based on the foregoing series of implementations, as a preferred implementation, selectively assigning the access rights of edge servers to low-cost nodes and/or client nodes, including:

The access rights of edge servers are selectively allocated to low-cost nodes and/or client nodes by sending edge server access addresses.

It should be noted that, the method of sending the edge server access address to the low-cost node and/or the client node in this embodiment, informing the low-cost node and/or the client node of the way to access the data stream, relatively ensures low cost. Efficiency with which cost nodes and client nodes obtain data flow in edge servers.
