Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
With the advent of the 5G era, in a 5G network, a data transmission speed is greatly increased, taking a communication network SMF/architecture as an example, in the current technology, a UPF (User Plane Function) network element offloading policy is set by an SMF (Session Management Function) network element, and a corresponding access request in the communication network is offloaded to an MEC (Mobile Edge Computing) Edge cloud, thereby increasing a data response speed. However, the access address of each target application needs to be preset by the MEC edge cloud, which results in that the access address of the UPF network element for accessing the target application is relatively fixed, and once a node in the data network fails or an interface is abnormal, the UPF network element cannot adjust the access address of the target application in time, which inevitably affects the response speed of data, and even causes that the target data cannot be obtained, which affects user experience.
In order to solve the above problems, the present application provides a 5G-based edge node scheduling method.
Fig. 1 shows a flowchart of a 5G-based edge node scheduling method according to an exemplary embodiment of the present application. Referring to fig. 1, a 5G-based edge node scheduling method is applied to an edge management node, where the 5G-based edge node scheduling method at least includes steps S11 to S14, and is described in detail as follows:
in step S11, a data request carrying a target node identifier and forwarded by a UPF network element is received, where the data request is forwarded by the UPF network element according to a network address IP segment corresponding to an autonomous domain of a service provider.
The target node may be an edge node that provides a data service required by a user (e.g., the data service may be data storage, data acquisition, or application support, etc.). It should be noted that one edge node may provide a single data service or may provide multiple data services, so the number of edge nodes may be one, or may be any number of two or more, and this is not particularly limited in this application.
The target node identifier may be identification information associated with the target node, and the corresponding target node may be determined according to the target node identifier. It should be noted that, the target node identifier described herein may not only uniquely determine a certain edge node, but also may be common attribute information that multiple edge nodes have, for example, have the same IP segment, correspond to the same domain name, be in the same area, or support the same data service.
The data request may be information to request a corresponding data service, such as may be an application access request. In an example, a user may click on a particular area in the terminal interface (e.g., a "confirm access" button, etc.) to generate a corresponding data request, which may contain a target node identification. The terminal device may transmit the data request in the 5G communication network to determine a target node corresponding to the target node identification.
In an exemplary embodiment of the present application, the client is connected to the 5G network through the base station, and the data request is sent to a User Plane Function (UPF) network element. The 5G operator sets an UPF (Session Management Function) offloading policy in advance through an SMF (Session Management Function) network element. According to the offloading policy, the UPF network element may forward the data request carrying the target node identifier to the corresponding edge management node, and forward the data request not carrying the target node identifier to the 5G core network. It should be noted that, in order to implement the edge node scheduling method based on 5G provided by the present application, a network service provider may cooperate with a 5G communication network operator to implement fusion of a communication network and a data network.
The destination node identifier may be a domain name, an IP segment, and a region where the client is located, which are preset in the edge management node, or may be a type and a function of content stored in the edge node. For example, the service provider sets an edge node in the IP segment of the network address corresponding to the autonomous domain to serve domain name a. The 5G operator configures a UPF shunt strategy through an SMF network element in the 5G communication network, the UPF receives a data request, and when the data request carries a target node identifier 'domain name A', the UPF determines that the access request is served by an edge node in a network address IP section corresponding to the autonomous domain of the service provider, so that the access request is forwarded to an edge management node.
In step S12, a resolution request for the target node identifier is generated, and the resolution request is sent to the scheduling node.
The resolution request may be information for requesting to determine the IP address of the target node. In an example, the resolution request may include a target node identifier, so that the IP address of the corresponding target node may be determined according to the target node identifier included in the resolution request.
The scheduling node may be a network device of a service provider, and the scheduling node may be a processing node having a node allocation function, and may determine, after receiving the resolution request, an IP address of a corresponding target node according to a target node identifier included in the resolution request, and feed back the IP address of the target node to the edge management node. It should be understood that one target node identifier may correspond to a plurality of edge nodes, and therefore, the scheduling node may determine a plurality of edge nodes corresponding to the target node identifier according to the target node identifier, and then select one of the plurality of edge nodes as a target node for feedback, for example, may determine the target node according to the optimal route or the node health value, and so on.
In an exemplary embodiment of the present application, an edge management node generates an analysis request for a target node identifier according to the target node identifier in a received data request, sends the analysis request to a scheduling node, and the scheduling node analyzes an IP address of the target node. For example, if the target node is identified as a domain name, a resolution request for the domain name is generated to cause the scheduling node to determine the edge node serving the domain name. If the target node is identified as the area where the client is located, a resolution request for the area is generated so that the scheduling node determines an edge node serving the area. And if the target node identifier is the combination of the domain name and the area where the client is located, generating an analysis request carrying information of the area where the client is located and aiming at the domain name, so that the scheduling node determines the edge node serving the domain name accessed by the client in the area.
In step S13, an IP address of a target node fed back by the scheduling node is received, where the target node is determined for the scheduling node according to a target node identifier.
In an exemplary embodiment of the present application, the scheduling node determines a target node according to the received parsing request, where the target node corresponds to a target node identifier included in the parsing request, and then feeds back an IP address of the target node to the edge management node. For example, the resolution request is a resolution request for an access area, and the scheduling node may determine, according to an area where the client is located, an edge node in the same area as the access area as a target node, and feed back an IP address of the target node to the edge management node.
In step S14, the IP address of the target node is fed back to the UPF network element.
In an exemplary embodiment of the present application, the edge management node may feed back an IP address of the target node, which is fed back by the scheduling node, to the UPF network element, and the UPF network element sends the IP address of the target node to the client used by the user, so that the client can establish a connection with the target node, thereby obtaining a corresponding data service.
In the embodiment shown in fig. 1, the edge management node generates a resolution request for the target node identifier in the data request, and the scheduling node performs resolution to determine the IP address of the target node. The scheduling node can schedule in the existing edge node, determines the target node from the scheduling node, solves the problem that an access address of a server side accessing the target application in the existing 5G communication network is relatively fixed, guarantees the robustness of the service, and guarantees the success rate of response of the data request. And the UPF network element forwards the IP section according to the network address corresponding to the autonomous domain of the service provider without modifying a specific access address list in the communication network or opening an address interface by a 5G operator, thereby not only ensuring the safety and reliability of the 5G communication network system, but also reducing the complexity of updating the address list. In addition, the transmission of the part of data does not need to pass through a 5G core network, so that the data response speed is improved, and the occupation of 5G core network resources is reduced.
Based on the embodiment shown in fig. 1, in an exemplary embodiment of the present application, before receiving a data request carrying a target node identifier and forwarded by a UPF network element, the method for scheduling an edge node based on 5G further includes:
acquiring a network address IP section corresponding to an autonomous domain of a service provider;
and registering the network address IP section corresponding to the autonomous domain of the service provider to the 5G communication network.
In this embodiment, the facilitator may be a CDN facilitator or an edge cloud computing facilitator, which may have a large number of edge nodes for caching data in the network/computing to provide target data to the user at close proximity. A facilitator may own its autonomous domain with a corresponding IP segment of the network address. Before providing network service, the autonomous domain and its corresponding network address IP segment need to be announced outwards to establish connection with devices in other domains.
The 5G communication network operator and the network service provider cooperate, a large number of edge nodes of the service provider can be used as MEC edge clouds, and high-speed data service is provided for terminal users accessing the 5G communication network. The operator of the 5G communication network needs to obtain the network address IP segment corresponding to the autonomous domain of the service provider, and register the network address IP segment corresponding to the autonomous domain of the service provider into the 5G communication network, for example, add the network address IP segment into the 5G communication record table, so that the IP address in the network address IP segment can be accessed by the 5G communication network. The edge nodes with the IP addresses in the IP segment of the network address can provide MEC edge cloud services for the 5G communication network, and the client can obtain data from the edge nodes.
Based on the embodiment shown in fig. 1, in an exemplary embodiment of the present application,
the generating a resolution request for the target node identifier includes:
acquiring the IP address of the scheduling node;
and generating a resolution request aiming at the target node identification, wherein the resolution address of the resolution request is the IP address of the scheduling node.
In this embodiment, the edge management node may obtain an IP address of the scheduling node system, and set a resolution address corresponding to the resolution request as the IP address of the scheduling node when generating the resolution request. Therefore, the edge management node can send the analysis request to the scheduling node for analysis, and the service provider side carries out analysis, so that the analysis flexibility is improved.
Fig. 2 shows a flowchart of a 5G-based edge node scheduling method according to another exemplary embodiment of the present application. Referring to fig. 2, the 5G-based edge node scheduling method is applied to a scheduling node, and the 5G-based edge node scheduling method at least includes steps S21 to S23, which are described in detail as follows:
in step S21, an analysis request for a target node identifier sent by an edge management node is received, where the analysis request is generated by the edge management node according to a data request carrying the target node identifier, and the data request is forwarded to the edge management node by a UPF network element according to a network address IP segment corresponding to an autonomous domain of a service provider.
In this embodiment, corresponding to the scheduling method of the edge management node on the operator side, on the service provider side, the scheduling node receives an analysis request for the target node identifier sent by the edge management node.
In step S22, according to the target node identifier, an IP address of the target node corresponding to the target node identifier is determined.
In this embodiment, the scheduling node resolves the IP address of the target node corresponding to the target node identification. Specifically, the scheduling node may search, according to the target node identifier, an edge node corresponding to the target node identifier, and then determine the IP address of the corresponding target node from the edge node. For example, if the target node identifier is a domain name, the scheduling node determines that the edge node serving the domain name is the target node; and if the target node is identified as the area where the client is located, the scheduling node determines that the edge node serving the area is the target node.
In step S23, the IP address of the target node is fed back to the edge management node.
In this embodiment, the scheduling node feeds back the IP address of the target node to the edge management node. And the edge management node feeds back the IP address of the target node to the client according to the path for receiving the request so as to connect the client and the target node and acquire the data content.
In the embodiment shown in fig. 2, the scheduling node receives a resolution request generated by the edge management node for the target node identifier in the data request, resolves the resolution request, and determines the IP address of the target node. The scheduling node can schedule in the existing edge node, determines the target node from the edge node, solves the problem that the access address of the server side accessing the target application in the existing 5G communication network is relatively fixed, guarantees the robustness of the service, and guarantees the response success rate of the data request. The service provider can flexibly determine the target node according to the actual situation, does not need 5G to update the address list, and does not need 5G operators to open an address interface, thereby not only ensuring the safety and the reliability of the 5G communication network system, but also reducing the complexity of updating the address list. In addition, the target node responds to the data request, and the data request and the response data are transmitted without passing through a 5G core network, so that the data response speed is improved, and the occupation of 5G core network resources is reduced.
In an exemplary embodiment, before receiving a resolution request for a target node identifier sent by an edge management node, the method for edge node scheduling based on 5G further includes:
and carrying out route announcement to a public network according to the network address IP section corresponding to the autonomous domain of the service provider.
In this embodiment, in order to enable the IP address in the IP segment of the network address corresponding to the autonomous domain of the service provider to be accessed by the 5G communication network, the service provider needs to publish a route announcement and broadcast, so that the 5G communication network can obtain the IP segment of the network address corresponding to the autonomous domain of the service provider and register the IP segment of the network address corresponding to the autonomous domain of the service provider in the 5G communication network. The edge node with the IP address in the network address IP segment corresponding to the facilitator autonomous domain can then be discovered by other devices in the network and establish a connection.
Fig. 3 shows a flowchart of a 5G-based edge node scheduling method according to another exemplary embodiment of the present application. Referring to fig. 3, in an exemplary embodiment, in step S22, determining the IP address of the target node according to the target node identifier includes steps S221 to S223, which are described in detail as follows:
in step S221, an edge node list corresponding to the target node identifier is obtained according to the target node identifier.
In this embodiment, the target node identifier may be identification information associated with the target node, and the edge node associated with the target node identifier may be determined according to the target node identifier. For example, when the target node is a domain name, the edge node of the server for the domain name may be determined to be the associated edge node. When a large number of clients accessing the domain name exist, a plurality of edge nodes can be set to serve the domain name at the same time, and at this time, the plurality of edge nodes can be obtained according to the target node identifier. When the scheduling node receives a data request for a certain domain name, the corresponding edge node list can be quickly determined.
In step S222, the health values of the edge nodes in the edge node list are detected, and the edge node with the health value greater than or equal to the predetermined threshold is selected as the candidate edge node.
The scheduling node can detect the edge nodes in the edge node list one by traversing the IP addresses of the edge node list, and detect the health value of each edge node. The health value of the edge node may be numerical information for representing the service capability of the edge node, which may be according to the service index of the edge node: determining factors such as throughput, response time, concurrency number, service success rate and the like, for example, monitoring the magnitude of each factor such as throughput, concurrency number, response time, service success rate and the like in unit time of the edge node, comparing the magnitude with a preset magnitude, and comprehensively calculating a score to serve as a health value of the edge node; or according to the resource index of the edge node: determining consumption conditions of resources such as a CPU, a memory, an I/O and the like, for example, detecting the consumption conditions of the resources such as the CPU, the memory, the I/O and the like of the edge node, and calculating a remaining resource score as a health value of the edge node; or respectively multiplying the health value determined according to the service index and the health value determined according to the resource index by a weight coefficient, and comprehensively determining. It should be noted that the higher the health value is, the stronger the service capability of the edge node is, and the lower the health value is, the weaker the service capability of the edge node is. In this embodiment, by presetting a health value threshold, only edge nodes whose health values are greater than the threshold can provide good services, and the edge nodes whose health values are greater than the predetermined threshold are candidate edge nodes.
In step S223, an edge node having an optimal route with the edge management node is determined as a target node from the candidate edge nodes.
In this embodiment, the candidate edge nodes are determined, one edge node may be randomly selected from the candidate edge nodes as a target node, and the IP address of the target node is fed back to the client, so that the client establishes a connection with the target node, and the target node provides a service for the client. In this embodiment, to further improve the response speed, the scheduling node further performs route detection on the candidate edge node, and takes the edge node having the optimal route with the edge management node as the target node. For example, the edge node that consumes the least time for information transmission may be determined as the target node, and so on.
The target node is selected by the method, so that the analyzed target node can be guaranteed to have good health degree, the service can be provided for the client, the target node and the edge management node also have the optimal route, and the service can be provided for the client at the fastest response speed.
In an exemplary embodiment, after the detecting the health value of the edge node in the edge node list, the method further includes:
and adding the edge nodes with the health values smaller than the preset threshold value into a fault list.
In this embodiment, after an edge node fails, the failed edge node may be added to a failure list. In order to prevent the failed edge node from being resolved by the scheduling node, the IP address of the failed edge node may be deleted from the edge node list. When the scheduling node is analyzed, the edge node list is traversed, the alternative edge nodes are determined, and after the IP address of the edge node with the fault is deleted from the edge node list, the edge node with the fault can not be analyzed again; or when the scheduling node traverses the IP addresses of the edge node list, the edge node list is compared with the fault list, and the IP addresses in the fault list are skipped over, so that the fault edge node is not resolved any more, and the terminal does not request the fault edge node. In the embodiment, when the node fails, timely adjustment is performed on the service provider side, and no adjustment is required on the operator side, so that the scheduling flexibility and timeliness are guaranteed.
In an embodiment, before the determining, according to the target node identifier, an IP address of a target node corresponding to the target node identifier, the method further includes:
and when detecting that a new edge node is accessed, adding the IP address of the newly accessed edge node into the IP address record of the corresponding network address IP section.
In this embodiment, when a new edge node is configured by a service provider, in order to enable the newly added edge node to provide a service for a user using a 5G network, the newly added edge node can be accessed by the 5G communication network only by setting the IP address of the newly added edge node as the IP address in the IP field of the network address, and meanwhile, in order to enable the newly added edge node to schedule the node to resolve, the IP address of the newly added edge node needs to be added into the edge node list. The above process does not need any adjustment by the 5G operator, and the trouble of modifying the address list of the operator for many times is avoided.
Based on the technical solution of the above embodiment, a specific application scenario of the embodiment of the present application is introduced as follows:
fig. 4 shows a scheduling diagram of a 5G-based edge node scheduling method according to an exemplary embodiment of the present application.
Referring to fig. 4, a 5G operator a establishes a 5G network in a certain city, providing 5G services to citizens. Operator a and facilitator B cooperate to use the edge node cluster of facilitator B as an EMC edge cloud (46). The service provider B sets a plurality of edge nodes in the city, wherein the edge nodes 1 to 10 provide services for the domain name a. The operator A divides the city into two areas and sets an edge management node (44); corresponding to the two areas, setting an edge management node 1 (441) in the area 1, and setting an access address list, wherein the access address list comprises an edge node 1 and an edge node 2; an edge management node (442) is provided in the area 2, and an access address list including the edge node 5 and the edge node 6 is provided.
A user (411) in the area 1 accesses a 5G network through a 5G base station to initiate a data request. After the UPF network element (43) receives the data request, if the domain name of the data request is not the domain name of the edge node service, the data request is forwarded to a 5G core network (47), and the user is connected with a source station or a public network (48) through the 5G core network (47) and acquires data. If the domain name of the data request is the domain name served by the edge node, the data request is forwarded to the edge management node (44). Because the target node identifier carried by the request contains the area information indicating that the target node identifier is from the area 1, the data request of the user is forwarded to the edge management node 1 (441), and the edge management node 1 (441) determines that the edge node 1 or the edge node 2 belonging to the area 1 responds to the access request of the user. When the edge node 1 fails, the operator a needs to modify the access address list of the edge management node 1, and cannot make adjustments in time. In this process, a large number of users will have no access.
After the service provider B negotiates with the operator A, the operator A registers the network address IP section corresponding to the autonomous domain of the service provider B to the 5G communication network, and sets an IP address in the network address IP section corresponding to the autonomous domain of the service provider B for the edge node, so that the edge node having the IP address in the IP section can provide edge cloud service for users of the 5G communication network. Simultaneously, the IP address of the scheduling node (45) is acquired.
Assuming that an edge node 1 and an edge node 5 are failed, after receiving a data request of a user (411) in an area 1 for accessing a domain name a, the edge management node 1 generates an analysis request for the domain name a, and sends the analysis request to a scheduling node (45) of a service provider B, the scheduling node (45) queries an edge node list according to the domain name a in the request, determines that the domain name a is served by the edge nodes 1-10, and the scheduling node (45) sequentially detects the edge nodes 1-10, wherein health values of the edge nodes 3, 4, 6, and 7 are greater than a preset threshold, the scheduling node further detects a route from the edge node to the edge management node 1, finally determines that the route from the edge node 4 to the edge management node 1 is shortest, selects the edge node 4 as a target node, and provides service to the user (411) in the area 1. And according to the detection result, if the health values of the edge nodes 1 and 5 are less than the preset threshold value, adding the edge nodes 1 and 5 into the fault list, and deleting the edge nodes 1 and 5 from the edge node list. When an edge management node 2 (442) receives a request of a user (412) in an area 2 for accessing a domain name a, an analysis request for the domain name a is generated, the analysis request is sent to a scheduling node (45) of a service provider B, the scheduling node (45) queries an edge node list according to the domain name a in the request, 8 edge nodes, namely an edge node 2-edge node 4 and an edge node 6-edge node 10, are determined to provide services, and the scheduling node sequentially detects the 8 edge nodes, wherein the health values of the edge node 3, the edge node 4, the edge node 6 and the edge node 7 are greater than a preset threshold value, the scheduling node (45) further detects a route from the edge node to the edge management node 2 (442), finally determines that the route from the edge node 7 to the edge management node 2 (442) is the shortest, selects the edge node 7 as a target node, and provides services to the user (412) in the area 2.
Through the embodiment, the operator registers the network address IP section of the service provider to the 5G communication network, a large number of edge nodes of the service provider can be used as MEC edge cloud providing service, the data response speed is accelerated, meanwhile, the scheduling node of the service provider provides analysis service, when the edge nodes break down, the intelligent scheduling node can timely adjust analysis results, and the operator side does not need to open corresponding interfaces. The method does not need to adjust the setting of the 5G core network, so that the operator side does not have security risk and the service is ensured to be stable; the edge node with the shortest route can be selected to provide service, and response timeliness is improved.
