Detailed Description
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, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
At present, service distribution modes of edge servers to client nodes and low-cost nodes are selectively regulated and controlled based on bandwidth use conditions of the edge server nodes, but because the edge server nodes are devices directly communicating with third-party service nodes, the working stability of the edge servers directly influences normal acquisition of data streams by the client nodes and the low-cost nodes, and it is difficult to ensure the overall efficiency and stability of a process of acquiring the data streams by a user through the client nodes in a shared computing scene.
The core of the invention is to provide a server allocation method to relatively improve the comprehensiveness of the factors referred to when the edge server is allocated, thereby further ensuring the overall efficiency and stability when the edge server provides data service. Another core of the invention is to provide a server distribution device, system and medium.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail 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. Referring to fig. 2, the specific steps of the server allocation method include:
step S10: the method comprises the steps of obtaining network parameters and hardware parameters of the edge server, and obtaining service feedback indexes of the edge server, which are transmitted by the low-cost nodes and the client nodes.
It should be noted that, the allocation control node first obtains a network parameter and a hardware parameter of the edge server, where the network parameter refers to relevant working state data involved when the edge server performs network data communication with an external device, and the hardware parameter refers to relevant working state data generated by occupying hardware resources when the edge server performs network data communication with the external device or performs a data processing task by itself. The execution main body of the method is the distribution control node, namely the distribution control node can carry out data communication with the edge server, and further can obtain the network parameters and the hardware parameters of the edge server.
In addition, it should be noted that, the method is based on a technical solution in a shared computing scenario, in the shared computing scenario, an edge server node directly pulls a data stream in a third-party service node, and then can provide the pulled data stream to a low-cost node or a client node, where the low-cost node refers to a node device established between the client node and the edge server, for example, in an actual application, the low-cost node may specifically be an NAS device, and when the NAS device can access and acquire the data stream in the edge server, the client node may indirectly acquire the data stream in the edge server through the NAS device, and the client node may also directly access the edge server and acquire the data stream in the edge server.
Step S11: and selectively distributing the access right of the edge server to the low-cost node and/or the client node according to preset conditions met by the network parameters, the hardware parameters and the service feedback indexes.
It should be noted that the key point of this step is that the allocation control node performs comprehensive analysis on the network parameters and the hardware parameters of the edge server, and further selectively allocates the access right of the edge server to the low-cost node and/or the client node according to the preset condition that the network parameters and the hardware parameters satisfy. It should be emphasized that the present embodiment focuses on comprehensively analyzing the network parameters and the hardware parameters, and on the basis of analyzing the network parameters, the situation that the edge server may occupy the hardware resources when consuming the network resources to provide services to the external device is considered, so that in this step, the current network parameters and hardware parameters of the edge server are used as the basis for allocating the edge server to the low-cost node and the client node, thereby relatively improving the comprehensiveness of the factors considered when allocating the edge server.
The server allocation method provided by the invention comprises the steps of firstly obtaining the network parameters and the hardware parameters of the edge server, obtaining the service feedback indexes of the edge server transmitted by the low-cost nodes and the client nodes, and further selectively allocating the access rights of the edge server to the low-cost nodes and/or the client nodes according to the preset conditions met by the service feedback indexes, the network parameters and the hardware parameters. Since it is considered that the edge server occupies the hardware resource of the edge server itself when providing data to the low-cost node and/or the client node, therefore, the method takes the network parameters and the hardware parameters of the edge server and the service conditions of the edge server at the low-cost node and the client node as the restriction factors for distributing the distribution mode of the edge server, and further selectively allocating the edge server to the low-cost node and/or the client node for providing the data stream of the third-party service node to the low-cost node and/or the client node, the method relatively improves the comprehensiveness of the reference factors when allocating the edge server, therefore, the overall efficiency and stability of the edge server in providing data services are further ensured.
On the basis of the above embodiment, as a preferred implementation, the network parameter includes a bandwidth usage rate;
correspondingly, before selectively allocating the access right of the edge server to the low-cost node and/or the client node according to the preset conditions met by the network parameters, the hardware parameters and the service feedback indexes, the method further comprises the following steps:
on the premise that the service feedback index meets the index condition, judging whether the bandwidth utilization rate is smaller than a bandwidth alert threshold value;
if yes, the step of selectively distributing the access right of the edge server to the low-cost node and/or the client node according to preset conditions met by the network parameters, the hardware parameters and the service feedback indexes is carried out.
It should be noted that the important point in the present embodiment is to determine whether to assign the access right of the edge server by determining whether the bandwidth usage rate of the edge server is smaller than the bandwidth guard threshold. The purpose of the bandwidth alert threshold is to define whether the bandwidth of the current edge server is in an alert state with a higher occupied degree, and the specific value of the bandwidth alert threshold should be determined according to the actual network communication performance of the edge server, which is not specifically limited herein. The 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 according to an embodiment of the present invention. Referring to fig. 3, the specific steps of the server allocation method include:
step S20: the method comprises the steps of obtaining network parameters and hardware parameters of the edge server, wherein the network parameters and the hardware parameters comprise bandwidth utilization rate, and obtaining service feedback indexes of the edge server, which are transmitted by the low-cost nodes and the client nodes.
In this embodiment, the network parameters acquired from the edge server at least include a bandwidth utilization rate, where the bandwidth represents data transmission capability during signal transmission, that is, identifies the amount of data passing through a link in a unit time, and since the link resource of the edge server is often limited, the total amount of the bandwidth is also constant, and the bandwidth utilization rate represents the occupied degree of the entire bandwidth of the edge server. In addition, the higher the bandwidth utilization rate is, the lower the reliability of the network state of the edge server is, that is, the lower the capability of the edge server to transmit data with the external device is.
Step S21: and when the value of the bandwidth utilization rate is smaller than the lowest bandwidth threshold value, the value of the hardware parameter is smaller than the hardware warning threshold value, and the service feedback index meets the index condition, the access right of the edge server is simultaneously distributed to the low-cost node and the client node.
Wherein the bandwidth minimum threshold is less than the bandwidth alert threshold.
Based on the above explanation of the bandwidth utilization, when the value of the bandwidth utilization is smaller than the lowest threshold of the bandwidth, it indicates that the current bandwidth utilization of the edge server is relatively low, and the edge server has a higher network communication performance. When the bandwidth of the edge server and the occupied degree of the hardware are both small, the edge server is indicated to have relatively sufficient network resources and hardware resources, so that the access right of the edge server is simultaneously allocated to the low-cost node and the client node in the situation, and the effective utilization of the whole resources of the edge server can be relatively ensured.
Step S22: and when the value of the bandwidth utilization rate is greater than or equal to the lowest 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 index meets the index condition, judging whether a preferred edge server with the equipment communication cost lower than that of the edge server and the working state consistent with that of the edge server exists, if so, executing a step S23, otherwise, executing a step S24.
Step S23: the access rights of the preferred edge server are assigned to both the low cost node and the client node.
Step S24: the access rights of the edge server are assigned to both the low cost node and the client node.
Wherein the free allocation threshold is less than the bandwidth alert threshold.
It should be noted that, when the value of the bandwidth utilization reaches or exceeds the range of the bandwidth minimum threshold, that is, is greater than or equal to the bandwidth minimum threshold and is less than the free allocation threshold, and the value of the hardware parameter is less than the hardware alert threshold, it indicates that the current hardware occupancy degree of the edge server is smaller, and the bandwidth is already occupied to a certain degree but has not yet reached a higher occupancy degree. When the bandwidth utilization value of the preferred edge server is equal to or larger than the lowest bandwidth threshold and smaller than the free allocation threshold, the value of the hardware parameter is smaller than the hardware warning threshold, and the equipment communication cost is lower than the preferred edge server of the edge server, the access right of the preferred edge server is allocated to the low-cost node and the client node at the same time, and on the contrary, if the preferred edge server does not exist, the access right of the edge server is allocated to the low-cost node and the client node at the same time, so that the overall cost of providing data service by the edge server in the network system is relatively reduced.
Step S25: and on the premise that the service feedback index meets the index condition, when the value of the bandwidth utilization rate is greater than or equal to the free allocation threshold and less than the bandwidth alert threshold, or the value of the hardware parameter is greater than the hardware alert threshold, allocating the access right of the edge server to the low-cost node only.
It should be noted that, when the value of the bandwidth utilization rate is greater than or equal to the free allocation threshold and less than the bandwidth alert threshold, it indicates that the current network resource occupation for the edge server is close to the alert condition; and when the value of the hardware parameter is greater than the hardware warning threshold value, the occupied degree of the hardware resource of the edge server is relatively large. In order to relatively ensure that the limited resources of the edge server can serve more client nodes, when either of the two cases is satisfied, the embodiment allocates the access right of the edge server to only the low-cost node, and since the client node can still indirectly access the data stream in the edge server through the low-cost node, after allocating the access right of the edge server to the low-cost node, the data stream can be provided to the client node through the low-cost node, and while relatively ensuring that the limited resources of the edge server can serve more client nodes, the client node is relatively prevented from further occupying the available resources of the edge server.
Step S26: and on the premise that the service feedback index meets the index condition, when the bandwidth utilization rate reaches a bandwidth exhaustion threshold value or the value of the hardware parameter reaches a hardware exhaustion threshold value, stopping allocating the access right of the edge server to the low-cost node and the client node.
The bandwidth exhaustion threshold is greater than the bandwidth alert threshold, and the hardware exhaustion threshold is greater than the hardware alert threshold.
It should be noted that, when the bandwidth utilization reaches the bandwidth exhaustion threshold, or the value of the hardware parameter reaches the hardware exhaustion threshold, in order to avoid the stability of the edge server being affected by the running-in and the downtime of the edge server, the access right of the edge server is stopped being allocated to the low-cost node and the client node in this embodiment.
In addition, it should be emphasized that, in the present embodiment, in determining the bandwidth utilization of the network parameter, a bandwidth minimum threshold, a free allocation threshold, a bandwidth alert threshold, and a bandwidth exhaustion threshold are respectively adopted, wherein the size relationship among the various thresholds is: the bandwidth minimum threshold value < the free allocation threshold value < the bandwidth alert threshold value < the bandwidth exhaustion threshold value, and the various threshold values measure the degree of the bandwidth utilization rate, so the specific values are determined according to the actual situation, for example, the bandwidth minimum threshold value is 20%, the free allocation threshold value is 85%, the bandwidth alert threshold value is 90%, and the bandwidth exhaustion threshold value is 95%; the aspect of judging the hardware parameter is based on a hardware alert threshold and a hardware exhaustion threshold, and the magnitude relation of the two is as follows: in the technology, as the hardware parameters can be further refined, the hardware alarm threshold and the hardware exhaustion threshold are corresponding to each specific hardware parameter.
In the above embodiment, as a preferred implementation, the hardware parameters include CPU utilization and memory utilization.
Since the CPU and the memory are important hardware factors that restrict the data processing efficiency of the edge server, the hardware parameters of the embodiment include the CPU utilization and the memory utilization, and thus the allocation accuracy of the edge server can be relatively accurately improved based on the CPU utilization and the memory utilization.
In a specific application scenario, the hardware alert thresholds of the CPU utilization rate and the memory utilization rate may be 85% respectively, and the hardware exhaustion threshold may be 95% respectively.
As a preferred embodiment, the service feedback indicators include connection power and response delay;
correspondingly, the service feedback index meets the index condition, which comprises the following steps:
when the connection success rate is greater than a preset success rate threshold and/or the response delay is greater than a preset delay threshold.
It should be noted that the network parameters of this embodiment include a connection success rate and a response delay, where the connection success rate represents a probability that a low-cost node or a client normally accesses the edge server when the edge server responds to the access of the low-cost node or the client node, and the response delay represents that the response of the edge server to the low-cost node or the client node is time-consuming after the low-cost node or the 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 reliability and efficiency of the data service provided by the edge server are high, so that the service efficiency and reliability of the low-cost node and the client node can be relatively ensured as a premise for allocating the access right of the edge server to the low-cost node and the client node.
As a preferred embodiment, before selectively allocating the access right of the edge server to the low-cost node and/or the client node according to the preset condition satisfied by the network parameter, the hardware parameter and the service feedback index, the method further comprises:
acquiring the number of client nodes accessed by an edge server;
correspondingly, according to preset conditions met by the network parameters, the hardware parameters and the service feedback indexes, selectively allocating the access right of the edge server to the low-cost node and/or the client node, including:
and when the number of the client nodes is smaller than a preset access threshold value, selectively allocating the access right of the edge server to the low-cost node and/or the client node according to preset conditions met by the network parameters, the hardware parameters and the service feedback indexes.
It should be noted that the key point of the present embodiment is to acquire the number of client nodes of the client node accessed by the edge server, analyze the number of client nodes of the client node accessed by the edge server, and selectively allocate the access right of the edge server to the low-cost node and/or the client node according to the preset condition satisfied by the network parameter and the hardware parameter when the number of client nodes is less than the preset access threshold, that is, the operation of selectively allocating the access right of the edge server to the low-cost node and/or the client node needs to be performed based on the number of client nodes of the edge server being less than the preset access threshold. The embodiment relatively ensures that the number of the nodes accessed to the edge server is in 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.
On the basis of the above series of embodiments, as a preferred embodiment, selectively assigning the access right of the edge server to the low-cost node and/or the client node includes:
and selectively distributing the access right of the edge server to the low-cost node and/or the client node by sending the access address of the edge server.
It should be noted that, in the present embodiment, a manner of sending an edge server access address to a low-cost node and/or a client node is adopted to notify the low-cost node and/or the client node of a path through which a data flow can be accessed, so that efficiency of acquiring the data flow in the edge server by the low-cost node and the client node is relatively ensured.
