Technical Field

Background

At present, with the increasing number of mobile terminals, the large-scale access of wireless networks, and the high performance requirement of user applications, the data traffic transmitted in the current network is continuously increased, and the load of servers is too high, in order to solve the problems of complex computation and large computation amount generated by applications, it is usually considered to offload the data to a cloud computing center for processing through network transmission. However, the cloud computing server is usually deployed in a centralized manner and is usually located at a relatively long physical location from the user terminal device, and the long-distance network data transmission inevitably causes delay and jitter.

The edge computing is a distributed computing architecture, and the application programs, data materials and services are migrated from a network center server to an edge server close to a mobile terminal for processing, so that delay can be reduced to a certain extent, and energy consumption is reduced. In the service migration process, accurate service scheduling is a key for ensuring that a user enjoys low-delay and high-quality service in an edge computing scene, currently, an edge site service server which is most matched with a mobile terminal is determined according to an IP address of the mobile terminal, and an access request of the user is scheduled to the edge site service server, but in the mobile edge computing scene, the position information of the mobile terminal cannot be accurately determined according to the IP address, so that the edge site service server determined according to the IP address is not the service server which is most matched with the mobile terminal, and therefore, the optimal service cannot be provided for the mobile terminal.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

As shown in fig. 1, the server scheduling system 100 includes a mobile terminal 101, a network 102, a scheduling server 103, an edge site server 104, and a cloud server 105. The mobile terminal 101 is a mobile terminal device used by a user, and may specifically be a mobile electronic device such as a tablet computer, a smart phone, a notebook computer, and the like, the user may log in an application platform at any geographic location through the mobile terminal 101, and send a service access request through the application platform, where the service access request is constructed according to first geographic location information and service access information of the mobile terminal, and may be, for example, a video-on-demand request, a cloud game acquisition request, and the like; the network 102 is used for providing a wired or wireless communication link between the mobile terminal 101 and the scheduling server 103, the edge site server 104 and the cloud server 105; the scheduling server 103 is configured to receive a service access request sent by the mobile terminal 101, determine a target service server according to first geographic position information in the service access request and second geographic position information of the edge site service server, and send attribute information of the target service server to the mobile terminal 101, so that the mobile terminal 101 accesses the target service server according to the attribute information of the target service server; the target service server is a service server capable of providing service for the user, which is determined according to the distance determined based on the first geographical location information of the mobile terminal 101 and the second geographical location information of the edge site service server and the service coverage radius of the edge site service server, and may be the edge site service server 104 or the cloud service server 105. The edge site service server 104 is a distributed service server deployed at a plurality of edge sites, and mainly aims to provide a nearby service access service for a relevant mobile user, reduce the time delay of service access, reduce the transmission bandwidth of a backbone network, and improve the experience quality of user service access; the cloud server 105 is a business server deployed in the cloud, and is mainly set for ensuring the continuity of business services under the condition that no edge site business server matched with the mobile terminal exists; the scheduling server 103, the edge site service server 104, and the cloud service server 105 may be independent servers, or may be a server cluster composed of a plurality of servers.

It should be understood that the number of mobile terminals, networks, dispatch servers, edge site service servers, and cloud service servers in fig. 1 are merely illustrative. According to actual needs, any number of mobile terminals, networks, scheduling servers, edge site service servers and cloud service servers can be provided.

In an embodiment of the present disclosure, the mobile terminal 101 collects geographical location information of itself at a predetermined time point, that is, first geographical location information, constructs a service access request according to the first geographical location information and the service access information, and then sends the service access request to the scheduling server 103 through the network 102. After receiving the service access request, the scheduling server 103 analyzes the service access request to acquire first geographical location information; then, the distance between the mobile terminal 101 and the edge site service server 104 may be calculated according to the first geographical location information and the second geographical location information of the edge site service server 104, and a target service server is determined according to the distance and the service coverage radius of the edge site service server 104, specifically, when the distance is less than or equal to the service coverage radius, the edge site service server 104 is the target service server, and when the distance is greater than the service coverage radius, the cloud service server 105 is used as the target service server; finally, the attribute information of the target service server may be returned to the mobile terminal 101, so that the mobile terminal 101 accesses the target service server according to the attribute information of the target service server. The server scheduling method in the embodiment of the disclosure can accurately determine the service server most matched with the mobile terminal according to the geographical position information of the mobile terminal based on a side cloud cooperation mode, and ensures the continuity of the service, thereby providing the best experience quality for the user.

In the related art, in order to solve the problem of accurate scheduling of services, in a fixed network, since fixed IP addresses are ordered plans, accurate scheduling of services is generally implemented by a scheduling server according to the IP address of a terminal, so as to schedule a service access request of a user to a service server on a best-matched multi-access edge site. Fig. 2 shows ｃA schematic diagram of ｃA system architecture for invoking ｃA service server in the related art, as shown in fig. 2, there are three fixed terminals A, B, C in the system, the IP addresses of the fixed terminals are IP-A, IP-B and IP-C, respectively, the three fixed terminals want to access the service server deployed at different multi-access edge sites, and send ｃA service access request to ｃA dispatch server, the dispatch server receives the service access request, reads the IP address of the fixed terminal, and determines ｃA service server matched with the fixed terminal according to the IP address and an address mapping relation table, taking the fixed terminal ｃA as an example, after receiving the service access request, the dispatch server reads the IP address IP- ｃA of the fixed terminal ｃA, and then determines that the service server most matched with the fixed terminal ｃA is the service server located at the multi-access edge Site 1(MEC Site-1) according to the IP- ｃA and the address mapping relation table, then, the service access request of the fixed terminal a is scheduled to the MEC Site-1, so that the fixed terminal a can enjoy the service with the best quality of experience.

Although the scheduling method in the related art can schedule a service server for a terminal to provide service, the scheduling method is mainly directed to a fixed network scenario, that is, as long as the scheduling server can accurately determine the location information of the terminal according to the IP address of the terminal and make IP address planning, the problem of accurate scheduling of the service can be solved. However, for the edge computing scenario of the mobile terminal, there is a scheduling accuracy problem in server scheduling according to the IP address of the terminal, on one hand, because different telecom operators allocate their own implementation schemes to the IP address of the mobile terminal, so that the IP address lacks sufficient geographical location information, for example, address fields of the IP addresses allocated to the area a and the area B by the telecom operators may be repeated, the same service server may be scheduled by the scheduling server according to the IP address of the mobile terminal located in the area a and the IP address of the mobile terminal located in the area B, but the service server is not the best matched with the mobile terminal in the area a or the mobile terminal in the area B, and thus cannot provide the best service for the remote user; on the other hand, because of the lack of IPv4 addresses, the address assigned by the mobile terminal in the telecom operating network is an internal network address, the access to the internet must pass through the NAT gateway of the operator, the source IP address read by the scheduling server is actually the address of the NAT gateway, and because the number of NAT gateways is limited, the location information of the mobile terminal cannot be effectively distinguished according to the address of the NAT gateway. In view of the above two situations, the scheduling server cannot schedule the service access request of the mobile terminal to the edge site service server that is most matched with the service access request, and thus cannot provide the best quality of service experience for the user.

For the problems in the related art, the embodiments of the present disclosure provide a server scheduling method, which may be a generic term based on a Cloud technology, and a Cloud technology (Cloud technology) is based on a network technology, an information technology, an integration technology, a management platform technology, an application technology, and the like applied in a Cloud computing business model, and may form a resource pool, be used as needed, and be flexible and convenient. Cloud computing technology will become an important support. Background services of the technical network system require a large amount of computing and storage resources, such as video websites, picture-like websites and more web portals. With the high development and application of the internet industry, each article may have its own identification mark and needs to be transmitted to a background system for logic processing, data in different levels are processed separately, and various industrial data need strong system background support and can only be realized through cloud computing.

Cloud computing (cloud computing) is a computing model that distributes computing tasks over a pool of resources formed by a large number of computers, enabling various application systems to obtain computing power, storage space, and information services as needed. The network that provides the resources is referred to as the "cloud". Resources in the "cloud" appear to the user as being infinitely expandable and available at any time, available on demand, expandable at any time, and paid for on-demand.

As a basic capability provider of cloud computing, a cloud computing resource pool (called as an ifas (Infrastructure as a Service) platform for short is established, and multiple types of virtual resources are deployed in the resource pool and are selectively used by external clients.

According to the logic function division, a PaaS (Platform as a Service) layer can be deployed on an IaaS (Infrastructure as a Service) layer, a SaaS (Software as a Service) layer is deployed on the PaaS layer, and the SaaS can be directly deployed on the IaaS. PaaS is a platform on which software runs, such as a database, a web container, etc. SaaS is a variety of business software, such as web portal, sms, and mass texting. Generally speaking, SaaS and PaaS are upper layers relative to IaaS.

Cloud processing is generally applied to the field of Big data, Big data (Big data) refers to a data set which cannot be captured, managed and processed by a conventional software tool within a certain time range, and is a massive, high-growth-rate and diversified information asset which can have stronger decision-making power, insight discovery power and flow optimization capability only by a new processing mode. With the advent of the cloud era, big data has attracted more and more attention, and the big data needs special technology to effectively process a large amount of data within a tolerance elapsed time. The method is suitable for the technology of big data, and comprises a large-scale parallel processing database, data mining, a distributed file system, a distributed database, a cloud computing platform, the Internet and an extensible storage system.

The embodiment of the present disclosure first provides a server scheduling method, where the server scheduling method is executed by a computer device, and the computer device includes, but is not limited to, a server or a mobile terminal. The server scheduling method may be performed by a scheduling server, such as the scheduling server 103 shown in fig. 1, and may be applied to any edge computing scenario, such as an edge computing application product for video-on-demand, cloud games, and the like. Fig. 3 schematically shows a flowchart of a server scheduling method according to an embodiment of the present disclosure, and referring to fig. 3, the server scheduling method at least includes steps S310 to S330, which are executed by a computer device and described in detail as follows:

in step S310, a service access request sent by a mobile terminal is received and analyzed to obtain first geographic location information of the mobile terminal in the service receiving request.

In an embodiment of the present disclosure, in order to invoke a service server that is most matched with a mobile terminal for the mobile terminal, the invoking server first needs to receive a service access request sent by an application platform of the mobile terminal, where the service access request is constructed by the application platform of the mobile terminal according to geographic location information and service access information of the mobile terminal. And then the calling server can analyze the service access request to obtain first geographical position information in the service access request, and determines a service server which is most matched with the mobile terminal according to the first geographical position information.

In step S320, a target service server is determined according to the first geographical location information and the second geographical location information of the edge site service server.

In one embodiment of the present disclosure, after the first geographical location information is obtained, the target service server may be determined according to the first geographical location information and the second geographical location information of the edge site service server. Fig. 4 is a flowchart illustrating a process of determining a target service server, and as shown in fig. 4, in step S401, a distance between the mobile terminal and the edge site service server is determined according to the first geographical location information and the second geographical location information; in step S402, comparing the distance with the service coverage radius of the edge site service server, and determining a target service server according to the comparison result; in step S403, when the distance is less than or equal to the service coverage radius, taking the edge site service server corresponding to the distance as a target service server; in step S404, when the distance is greater than the service coverage radius, the cloud service server is taken as the target service server.

In an embodiment of the present disclosure, the server scheduling system is specifically a distributed edge computing service system, where a plurality of edge site service servers located at different edge sites may be set, and when the distance between the mobile terminal and each edge site service server is calculated in step S401, the distance between the mobile terminal and each edge site service server may be calculated according to the first geographical location information and the second location of each edge site service server, and then, in step S402, the distance between the mobile terminal and each edge site service server is compared with the service coverage of each edge site service server, so as to determine the target service server. For example, the first geographical location information of the mobile terminal M is P₀In the server scheduling system, three edge site service servers S exist₁、S₂、S₃Respectively corresponding to different second geographical position information P₁、P₂、P₃Then, based on the first geographical position information P₀And second geographical position information P₁Determining a mobile terminal M and an edge site service server S₁A distance D between₁According to the first geographical position information P₀And second geographical position information P₂Determining a mobile terminal M and an edge site service server S₂A distance D between₂According to the first geographical position information P₀And second geographical position information P₃Determining a mobile terminal M and an edge site service server S₃A distance D between₃Then according to the distance D₁And edge site service server S₁Radius of service coverage R₁Determining whether mobile terminal M is at edge site service server S₁Within the service coverage radius of (1), if any, the edge site service server S₁It can be used as a target service server, if not, the edge site service server S₁It cannot act as a target service server and, as such, is dependent on the distance D₂And edge site service server S₂Radius of service coverage R₂Determining whether mobile terminal M is at edge site service server S₂Within the service coverage radius, and according to the distance D₃And edge site service server S₃Radius of service coverage R₃Determining whether mobile terminal M is at edge site service server S₃And determining the target service server according to the judgment result.

In one embodiment of the present disclosure, if it is determined that the mobile terminal is within the service coverage of the plurality of edge site service servers, the edge site service servers may all serve as target service servers, and the scheduling server may select one of the edge site service servers as a target service server and return the attribute information thereof to the mobile terminal. However, in order to provide the optimal service to the user, the edge site service server closest to the mobile terminal is necessarily the service server that is most matched with the mobile terminal and can provide the optimal service to the user, and therefore, the edge site service server having the smallest distance from the mobile terminal may be used as the target service server, and the attribute information thereof may be returned to the mobile terminal. Further, when the mobile terminal exceeds the service coverage of each edge site service server, in order to ensure the continuity of the service, the cloud service server may be used as a target service server, and the attribute information of the cloud service server is returned to the mobile terminal.

In step S330, the attribute information of the target service server is sent to the mobile terminal, so that the mobile terminal accesses the target service server according to the attribute information of the target service server.

In one embodiment of the present disclosure, after determining the target service server, the attribute information of the target service server may be sent to the mobile terminal, so that the mobile terminal accesses the target service server according to the attribute information of the target service server. When the target service server is a target edge site service server, the IP address, the position information and the service coverage radius of the target edge site service server can be sent to the mobile terminal, so that the mobile terminal can access the target edge site service server according to the IP address of the target edge site service server; and when the target business server is the cloud business server, the IP address of the cloud business server is sent to the mobile terminal, so that the mobile terminal can access the cloud business server according to the IP address of the cloud business server.

In one embodiment of the present disclosure, since the mobile terminal has a roaming characteristic, the first geographic location information of the mobile terminal is changed, for example, the service server that is most matched with the mobile terminal at the first time is the edge site service server S₁However, at the second moment, the first geographical location information of the mobile terminal changes, which results in the mobile terminal exceeding the edge site service server S₁To the edge site service server S₁Can not be carried by the mobile terminalThe service is provided for service, so that the service is interrupted, and the user experience is influenced. In order to avoid the above situation, after the mobile terminal establishes a connection with the target service server, the mobile terminal may obtain current terminal location information at a preset time point, where the current terminal location information may be the same geographical location information as the first geographical location information or different geographical location information from the first geographical location information, and according to the current terminal location information and the edge site service server S, the current terminal location information and the edge site service server S may be obtained by the mobile terminal₁The position information of the mobile terminal and the edge site service server S₁And determines the distance between the mobile terminal and the edge site service server S₁Whether the distance between them exceeds the edge site service server S₁The radius of service coverage. When mobile terminal and edge site service server S₁The distance between the two is greater than the service server S of the edge site₁When the service coverage radius is larger than the preset value, the mobile terminal can construct an updating service access request according to the current terminal position information and the service access information and send the updating service access request to the scheduling server. After receiving the update service access request, the scheduling server analyzes the update service access request to acquire the current terminal position information, updates the target service server according to the current terminal position information and the second position of the edge site service server, and then sends the updated attribute information of the target service server to the mobile terminal so that the mobile terminal can access the updated target service server according to the updated attribute information of the target service server.

In an embodiment of the present disclosure, the target service server that is most matched with the mobile terminal at the first time may be a cloud service server, that is, the calling server does not match the optimal edge site service server according to the first geographic location information of the mobile terminal at the first time, so that the cloud service server is allocated to the mobile terminal. Considering that the geographic position of the cloud service server is far away from the mobile terminal, and the problems of time delay, low transmission efficiency and the like exist when the mobile terminal is provided with service, the mobile terminal can acquire the current terminal position information at a preset time point, construct an update service access request according to the current terminal position information and the service access information, and send the update service access request to the scheduling server. After receiving the update service access request, the scheduling server analyzes the update service access request to acquire the current terminal position information, updates the target service server according to the current terminal position information and the second position of the edge site service server, and then sends the updated attribute information of the target service server to the mobile terminal so that the mobile terminal can access the updated target service server according to the updated attribute information of the target service server.

In an embodiment of the present disclosure, the preset time point may be a time point set by the system, or a time point calculated and determined by the system according to a certain rule, for example, the current terminal location information of the mobile terminal is obtained by monitoring every half hour, and the like. The updated target service server may be an edge site service server or a cloud service server, that is, the target service server providing the service may be switched from the edge site service server to another edge site service server, may be switched from the edge site service server to the cloud service server, may be switched from the cloud service server to the edge site service server, or may keep the cloud service server unchanged.

In an embodiment of the present disclosure, when the scheduling server parses a service access request sent by the mobile terminal to obtain the first geographic location information, a failure may occur, for example, the service access request does not include the first geographic location information, includes the first geographic location information but has a parsing error, and so on, and then the target service server cannot be determined according to the first geographic location information. The server calling method disclosed by the invention can be downward compatible with the traditional server scheduling scheme applied to the distributed edge computing scene, can support server scheduling based on the source IP address and server scheduling based on the geographic position, improves the stability and reliability of the server scheduling system, ensures that a service server matched with the mobile terminal provides service for a user under any condition, ensures the continuity of the service and further improves the user experience.
