Description

Technical Field

[0001] The present invention relates to the field of data communication networks, and in particular to a service scheduling method, device, communication equipment and storage medium. Background Art

[0002] The network status and the resource information of the data center are not aware of each other. The network cannot perceive the service and resource deployment information within the data center. When a user requests a service, the network cannot direct the service request to the best service node, affecting the user experience and reducing the efficiency of computing resources in the network.

[0003] Currently, these issues can be addressed through distributed routing scheduling and service deployment combined with centralized service scheduling. Distributed routing scheduling primarily leverages a computing network architecture to establish a unified resource and service view across the entire network's computing resources, enabling mutual awareness of network status and data center service and resource status. Distributed computing routing nodes then forward user computing power requests to the optimal node. This approach often performs scheduling within several adjacent areas, limiting its applicability. Service deployment combined with centralized service scheduling draws on the centralized management and cloud computing pooling scheduling concepts of Network Functions Virtualization (NFV) / Software Defined Networking (SDN). Through a centralized controller, computing power and network information is collected from ubiquitous computing devices, and application management, scheduling, and deployment and distribution are performed. This provides users with optimal computing power allocation and network connectivity solutions. However, with a centralized controller, service scheduling is centralized within the controller, resulting in excessive latency and a high risk of becoming a performance bottleneck.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] The technical solutions of the embodiments of the present invention can be applied to various communication systems, such as a Global System of Mobile Communication (GSM) system, a Long Term Evolution (LTE) system, or a 5G system. Optionally, a 5G system or a 5G network may also be referred to as a New Radio (NR) system or an NR network.

[0050] Exemplarily, the communication system applied in the embodiment of the present invention may include a network device and a terminal device (also referred to as a terminal, a communication terminal, etc.); the network device may be a device that communicates with the terminal device. The network device may provide communication coverage within a certain area and may communicate with terminals located in the area. Optionally, the network device may be a base station in each communication system, such as an evolved base station (eNB, Evolutional Node B) in an LTE system, or a base station (gNB) in a 5G system or NR system.

[0051] It should be understood that in the embodiments of the present application, devices having communication functions in the network / system may be referred to as communication devices. Communication devices may include network devices and terminals having communication functions. The network devices and terminal devices may be the specific devices described above and will not be described in detail here. Communication devices may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities, which are not limited in the embodiments of the present invention.

[0052] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0053] Figure 1 Schematic diagram of the system architecture of the application of the service scheduling method according to the embodiment of the present invention; Figure 1As shown, the system includes a centralized controller and various computing nodes. Different regions have different computing nodes. For example, domain 1 shown in the figure includes computing nodes R1 to R7, and domain 2 includes computing nodes R1 to R7. Different domains have different edge nodes or entry nodes. It should be noted that in actual applications, the system is not limited to the two domains shown in the figure and the number of nodes in each domain. More domains may be included in the system, and each domain may include fewer or more computing nodes. This is not limited in this embodiment.

[0054] In the system architecture of this embodiment, for each domain, the computing power information of each computing node is announced within the domain. For example, for domain 1, each computing node sends its own node information to other computing nodes in the domain, so that each computing node in the domain can obtain the node information of each computing node in the domain.

[0055] In the system architecture of this embodiment, a specific computing node is set up for each domain, such as computing node R7 in domain 1 and computing node R1 in domain 2. This specific computing node can obtain computing power information of nodes in its respective domain and report the obtained computing power information to the centralized controller so that the centralized controller can generate global computing power information. In other embodiments, this specific computing node can also be called an inter-domain node or inter-domain router, etc.

[0056] At least based on the above system architecture, the following embodiments of the present invention are proposed.

[0057] An embodiment of the present invention provides a service scheduling method. Figure 2 Schematic diagram of the process of the service scheduling method according to an embodiment of the present invention Figure 1 ;like Figure 2 As shown, the method includes:

[0058] Step 101: When there is no node supporting the service corresponding to the service request in a first domain or a second domain, a network device receives a service request sent by a first node; the first node is a node in the first domain or the second domain that receives the service request sent by a user equipment; the first domain and the second domain are each other's announcement domains;

[0059] Step 102: The network device determines a second node based on pre-acquired global computing power information.

[0060] The service scheduling method of this embodiment is applied to a network device, and the network device may be Figure 1 In other embodiments, the network device may also be called a control device, a controller, a centralized control device, etc., and this embodiment does not limit the name.

[0061] In this embodiment, a new notification domain is added. For example, the first domain and the second domain serve as each other's notification domains. Of course, the number of domains serving as each other's notification domains is not limited to two, and more than two domains may serve as each other's notification domains. This embodiment does not impose any restrictions on this. In actual applications, the first domain and the second domain may be determined to serve as each other's notification domains through pre-configuration or pre-agreed agreement.

[0062] In the notification domain, each node can obtain the computing power information of other nodes in the domain through the computing power information notification within the domain. In addition, it can also obtain the computing power information of each node in the notification domain and other domains except the domain where it is located. For example Figure 1 Node R1 in domain 1 can obtain the computing power information of each node in domain 2. After receiving a service request from a user device, the first node can query within the announcement domains (first and second domains) whether there is a node that supports the service corresponding to the service request. If no node supports the service corresponding to the service request, the first node sends the service request to the network device, which determines a second node that supports the service corresponding to the service request based on the pre-acquired global computing power information.

[0063] The nodes in this embodiment may also be referred to as computing nodes. The first node is the node that receives the service request from the user equipment. Since it is at the edge (i.e., the first node can communicate directly with the user equipment), it may also be referred to as an edge node or an entry node. For example, the first node may be the node closest to the user equipment, such as Figure 1 The computing node R1 in .

[0064] The present invention combines distributed and centralized scheduling. This approach leverages the local nature of entry nodes (e.g., the first node) to achieve scheduling within the communication domain. Global scheduling is achieved through a centralized controller (e.g., a network device). This approach improves the real-time nature of scheduling and enhances service efficiency. It also avoids the limited scope of distributed routing scheduling and reduces the excessive latency associated with centralized service scheduling.

[0065] In this embodiment, the network device pre-acquires global computing power information, which includes computing power information of each node in the first domain and the second domain, as well as computing power information of nodes in other domains. Because the first node does not find a node that supports the service corresponding to the service request within the notification domains (the first domain and the second domain) through querying, the network device determines a second node that supports the service corresponding to the service request by querying the global computing power information. The second node is a node in a domain other than the first domain and the second domain, and the second node provides the corresponding service for the service request of the user device through the second node.

[0066] In some optional embodiments of the present invention, the method also includes: the network device sends the service call request to the second node; wherein, the second node is a node within a third domain, and the third domain is different from the first domain and the second domain; the second node supports the service corresponding to the service request, or the second node can schedule other nodes that support the corresponding service for the service request.

[0067] In this embodiment, the second node may be a node in a third domain that is different from the first and second domains. As one embodiment, if the second node itself supports the service corresponding to the service request, the network device sends the service request to the second node, and the second node provides the corresponding service. As another embodiment, the second node is an entry node, entry gateway, or functional node with a scheduling function. After querying the global computing power information, the network device sends the service request to the second node. The second node determines the node that supports the service corresponding to the service request by querying the computing power information within its domain.

[0068] In some optional embodiments of the present invention, the method further includes: the network device sending the information of the second node to the user equipment via the first node, so that the user equipment can initiate a service request to the second node based on the information of the second node.

[0069] In some optional embodiments of the present invention, the method also includes: the network device receives first computing power information sent by a third node and second computing power information sent by a fourth node, respectively, the first computing power information includes computing power information of at least some nodes in the first domain; the second computing power information includes computing power information of at least some nodes in the second domain; the third node is a node that supports sending the first computing power information of the first domain to the network device, and the fourth node is a node that supports sending the second computing power information in the second domain to the network device; the first node is the same as or different from the third node, or the first node is the same as or different from the fourth node; the global computing power information is generated or updated based on the first computing power information and the second computing power information.

[0070] In this embodiment, the third node and the fourth node can be respectively used as specific computing nodes in their respective domains, or can also be called inter-domain nodes or inter-domain routing devices, etc. The third node and the fourth node have the function of reporting the computing power information of at least some nodes in their respective domains to the network device. For example, the third node can be Figure 1 The computing node R7 in the middle domain 1, the fourth node can be Figure 1Computing node R1 in domain 2 in the first domain. Through the intra-domain notification mechanism, the third node can obtain the computing power information of at least some nodes in the first domain, that is, the first computing power information, and the fourth node can obtain the computing power information of at least some nodes in the second domain, that is, the second computing power information. Through the inter-domain notification mechanism, the third node reports the obtained first computing power information to the network device, and the fourth node reports the obtained second computing power information to the network device.

[0071] For example, in the case of the first inter-domain advertisement, the first computing power information may include the computing power information of all nodes in the first domain, and the second computing power information may include the computing power information of all nodes in the second domain. Of course, the network device also obtains the computing power information of all nodes in other domains. Furthermore, the network device may generate global computing power information based on at least the obtained first computing power information and the obtained second computing power information.

[0072] In the case of a non-initial inter-domain announcement, the first computing power information may include computing power information of some nodes in the first domain, or may include computing power information of all nodes; correspondingly, the second computing power information may include computing power information of some nodes in the second domain, or may include computing power information of all nodes. The network device may update global computing power information based on the first computing power information and the second computing power information.

[0073] Exemplarily, the above-mentioned computing power information (such as computing power information of each node, first computing power information, second computing power information, global computing power information, etc.) may include at least one of the information such as computing power deployment location, service type supported by the node, service identification, computing power resource type, real-time status of computing power, etc.

[0074] In this embodiment, the first node is the same as or different from the third node, that is, the first node may be a node that performs inter-domain announcements within the first domain, or may not be a node that performs inter-domain announcements; or, the first node is the same as or different from the fourth node, that is, the first node may be a node that performs inter-domain announcements within the second domain, or may not be a node that performs inter-domain announcements.

[0075] In this embodiment, for each domain, the computing power information of at least some nodes in the domain is reported through a specific node (such as the third node in the first domain and the fourth node in the second domain). There is no need for each node to report the computing power information separately, which greatly reduces the amount of information reported in the computing power information.

[0076] In some optional embodiments, the method further includes: the network device sending the first computing power information to the fourth node, and sending the second computing power information to the third node.

[0077] In this embodiment, when inter-domain notification is performed for the first time, the first computing power information may include the computing power information of all nodes in the first domain, and the second computing power information may include the computing power information of all nodes in the second domain. The network device then sends the first computing power information to the fourth node and the second computing power information to the third node, so that each node in the notification domain can not only obtain the computing power information of each node in its own domain, but also obtain the computing power information of all nodes in the notification domain other than its own domain. This allows each node in the notification domain to generate node computing power information corresponding to the notification domain, and this node computing power information includes the computing power information of all nodes in the notification domain. When inter-domain notification is not performed for the first time, the first computing power information may include the computing power information of some nodes in the first domain, or the computing power information of all nodes; accordingly, the second computing power information may include the computing power information of some nodes in the second domain, or the computing power information of all nodes. The network device then sends the first computing power information to the fourth node and the second computing power information to the third node, thereby enabling each node within the advertised domain to update its stored node computing power information corresponding to the advertised domain. Thus, in step 101, the first node can determine whether there is a node that supports the service corresponding to the service request based on the acquired computing power information of each node within the first and second domains.

[0078] In some optional embodiments of the present invention, the method further includes: the network device monitors the number of service requests regarding the service, and when the number of service requests reaches a preset threshold, determines a fifth node within the first domain and / or the second domain, and sends a deployment instruction for the service to the fifth node.

[0079] In this embodiment, when a certain type of service request is consistently unsatisfied within the advertised domain, the network device may consider deploying the corresponding service within the advertised domain. Specifically, by monitoring the number of service requests for the service, it indicates that nodes within the first and second domains are unable to provide the service corresponding to the service request. Upon detecting that the number reaches a preset threshold, the network device identifies a fifth node within the advertised domain and sends a deployment instruction for the service to the fifth node. Specifically, the network device issues a service replica corresponding to the service request to the fifth node, thereby deploying the service on the fifth node. This improves service deployment efficiency.

[0080] Based on the above embodiments, an embodiment of the present invention further provides a service scheduling method. Figure 3 Schematic diagram of the process of the service scheduling method according to an embodiment of the present invention Figure 2 ;like Figure 3 As shown, the method includes:

[0081] Step 201: A first node receives a service request from a user equipment; the first node is a node in a first domain or a second domain, and the first domain and the second domain are each other's announcement domains;

[0082] Step 202: The first node searches for a node in the notification domain that supports the service corresponding to the service request;

[0083] Step 203: When no node supporting the service corresponding to the service request is found in the notification domain, the first node sends the service request to a network device.

[0084] The service scheduling method of this embodiment is applied to the first node. The first node may be Figure 1 The first node is a node that receives the service request from the user equipment. Since it is at the edge (i.e., the first node can directly communicate with the user equipment), it can also be called an edge node or an entry node. For example, the first node can be the node closest to the user equipment, such as Figure 1 The computing node R1 in .

[0085] In this embodiment, a new notification domain is added. For example, the first domain and the second domain serve as each other's notification domains. Of course, the number of domains serving as each other's notification domains is not limited to two, and more than two domains may serve as each other's notification domains. This embodiment does not impose any restrictions on this. In actual applications, the first domain and the second domain may be determined to serve as each other's notification domains through pre-configuration or pre-agreed agreement.

[0086] In the notification domain, each node can obtain the computing power information of other nodes in the domain through the computing power information notification within the domain. In addition, it can also obtain the computing power information of each node in the notification domain and other domains except the domain where it is located. For example Figure 1 Node R1 in domain 1 can obtain the computing power information of each node in domain 2. After receiving a service request from a user device, the first node can query within the announcement domains (first and second domains) whether there is a node that supports the service corresponding to the service request. If no node supports the service corresponding to the service request, the first node sends the service request to the network device, which determines a second node that supports the service corresponding to the service request based on the pre-acquired global computing power information.

[0087] The present invention combines distributed and centralized scheduling. This approach leverages the local nature of entry nodes (e.g., the first node) to achieve scheduling within the communication domain. Global scheduling is achieved through a centralized controller (e.g., a network device). This approach improves the real-time nature of scheduling and enhances service efficiency. It also avoids the limited scope of distributed routing scheduling and reduces the excessive latency associated with centralized service scheduling.

[0088] In some optional embodiments of the present invention, the method further includes: when the first node finds a node that supports the service corresponding to the service request in the notification domain, sending the service request to the node.

[0089] In some optional embodiments of the present invention, the method also includes: when the first node supports sending the first computing power information within the first domain to the network device, the first node sends the first computing power information to the network device, and the first computing power information includes the computing power information of at least some nodes within the first domain; or, when the first node supports sending the second computing power information within the second domain to the network device, the first node sends the second computing power information to the network device, and the second computing power information includes the computing power information of at least some nodes within the second domain; the first computing power information and / or the second computing power information are used by the network device to generate or update global computing power information.

[0090] In this embodiment, the first domain and the second domain each have a specific node configured to report computing power information of at least some of the nodes within the domain to a network device. If the first node supports sending first computing power information within the first domain to the network device, the first node sends the first computing power information to the network device. If the first node supports sending second computing power information within the second domain to the network device, the first node sends the second computing power information to the network device. By reporting computing power information of at least some of the nodes within the domain to the network device, the network device generates or updates global computing power information based on the computing power information reported by the specific nodes in each domain.

[0091] In some optional embodiments of the present invention, the method further includes: when the first node supports sending the first computing power information of the first domain to the network device, the first node receives the second computing power information sent by the network device, and sends the second computing power information to other nodes in the first domain; or, when the first node supports sending the second computing power information of the second domain to the network device, the first node receives the first computing power information sent by the network device, and sends the first computing power information to other nodes in the second domain.

[0092] In this embodiment, in order to realize scheduling within the notification domain, when the first node is a specific node within the first domain (that is, the first node supports sending the first computing power information of the first domain to the network device), the first node receives the second computing power information sent by the network device, and sends the second computing power information to other nodes within the first domain, so that each node in the first domain can obtain the computing power information of each node in the second domain in addition to knowing the computing power information of each node in the domain; correspondingly, when the first node is a specific node in the second domain (that is, the first node supports sending the second computing power information of the second domain to the network device), the first node receives the first computing power information sent by the network device, and sends the first computing power information to other nodes within the second domain, so that each node in the second domain can obtain the computing power information of each node in the first domain in addition to knowing the computing power information of each node in the domain.

[0093] As an example, in the case of the first inter-domain announcement, the first computing power information may include the computing power information of all nodes in the first domain, and the second computing power information may include the computing power information of all nodes in the second domain. If the first node is a specific node in the first domain, the first node receives the second computing power information sent by the network device and sends the second computing power information to other nodes in the first domain. In this way, each node in the first domain can generate node computing power information corresponding to the announcement domain based on the first computing power information and the second computing power information. This node computing power information includes the computing power information of all nodes in the announcement domain. The same applies to the case where the first node is a specific node in the second domain and is not further described here.

[0094] As another example, in the case where this is not the first inter-domain announcement, the first computing power information may include the computing power information of some nodes in the first domain, or the computing power information of all nodes; correspondingly, the second computing power information may include the computing power information of some nodes in the second domain, or the computing power information of all nodes. In the case where the first node is a specific node in the first domain, the first node receives the second computing power information sent by the network device and sends the second computing power information to other nodes in the first domain, so that each node in the first domain can update its own stored node computing power information corresponding to the announcement domain. The same applies to the case where the first node is a specific node in the second domain, which will not be repeated here.

[0095] In some optional embodiments of the present invention, the first node searches for a node supporting the service corresponding to the service request within the notification domain, including: the first node searches for a node supporting the service corresponding to the service request based on the second computing power information and the first computing power information. In this way, the computing power information of each node within the notification domain (i.e., the first domain and the second domain) (i.e., the node computing power information corresponding to the notification domain) is obtained by the first node to search for a node supporting the service corresponding to the service request.

[0096] In some optional embodiments of the present invention, the method also includes: the first node receives information of the second node sent by the network device, and sends the information of the second node to the user device; the second node supports the service corresponding to the service request, or the second node can schedule other nodes that support the corresponding service for the service request.

[0097] In this embodiment, the second node may be a node in a third domain that is different from the first domain and the second domain. As an implementation method, the second node itself supports the service corresponding to the service request; as another implementation method, the second node can schedule other nodes that support the corresponding service for the service request, that is, the second node is an entry node, entry gateway or functional node with a scheduling function. After querying the global computing power information, the network device sends the service request to the second node, and the second node determines the node that supports the service corresponding to the service request by querying the computing power information in its domain. The network device then sends the information of the second node to the user device through the first node, so that the user device can initiate a service request to the second node based on the information of the second node, so that the second node that supports the corresponding service can provide the service, or the second node can schedule the service request to other nodes in its domain, and other nodes can provide the service.

[0098] The service scheduling method according to an embodiment of the present invention is described below with reference to a specific example. In the following example, domains 1 and 2 are used as notification domains. Domain 1 includes nodes 1 and 2, where node 2 is a specific node (or domain boundary node). Domain 2 includes nodes 1 and 2, where node 1 is a specific node (or domain boundary node). Of course, domains 1 and 2 may also include other nodes. The following example only uses two nodes as an example for description.

[0099] Example 1

[0100] This example is an example of computing power information notification. Figure 4 Schematic diagram of the interactive process of the service scheduling method according to an embodiment of the present invention Figure 1 ;like Figure 4 As shown, the method includes:

[0101] Step 301: Nodes in domains 1 and 2 communicate computing power information to each other; this includes other nodes in domain 1 (such as node 1) communicating computing power information to node 2, and other nodes in domain 2 (such as node 2) communicating computing power information to node 1.

[0102] For example, taking domain 1 as an example, the nodes in domain 1 notify each other of computing power information, that is, node 2 receives the computing power information of node 1 (of course, it also receives the computing power information notified by other nodes in the domain).

[0103] Step 302: Node 2 in domain 1 notifies the computing power information to the network device, and node 1 in domain 2 notifies the computing power information to the network device.

[0104] For example, taking domain 1 as an example, node 2 in domain 1 generates first computing power information from the computing power information of at least some nodes in the domain and sends the first computing power information to the network device. If this is the first inter-domain announcement, the first computing power information may include the computing power information of all nodes in domain 1. If this is not the first inter-domain announcement, the first computing power information may include the computing power information of some nodes in domain 1 or the computing power information of all nodes in domain 1.

[0105] Step 303: The network device generates or updates global computing power information based on the received computing power information of each domain.

[0106] Step 304: The network device sends the inter-domain computing power information for the announced domain. For example, in step 304a, the network device sends the computing power information of domain 2 (i.e., the second computing power information) to node 2 of domain 1. In step 304b, the network device sends the computing power information of domain 1 (i.e., the first computing power information) to node 1 of domain 2.

[0107] Step 305: Specific nodes in each domain communicate computing power information between domains. For example, in step 305a, Node 2 in Domain 1 communicates the computing power information of Domain 2 (i.e., the second computing power information) to other nodes in Domain 1 (e.g., Node 1). In step 305b, Node 1 in Domain 2 communicates the computing power information of Domain 1 (i.e., the first computing power information) to other nodes in Domain 2 (e.g., Node 2).

[0108] Example 2

[0109] This example is an example of business scheduling. Figure 5 Schematic diagram of the interactive process of the service scheduling method according to an embodiment of the present invention Figure 2 ;like Figure 5 As shown, the method includes:

[0110] Step 401: User equipment sends a service request to a nearby node (eg, node 1 in domain 1).

[0111] Step 402: Node 1 of domain 1 queries the computing power information in the notification domain to determine whether there is a node that supports the service corresponding to the service request.

[0112] Step 403: If it is determined that there is no node supporting the service corresponding to the service request, send the service request to the network device.

[0113] Step 404: The network device determines node 3 (equivalent to the second node in the aforementioned embodiment) by searching the global computing power information.

[0114] The node 3 supports the service corresponding to the service request, or can schedule other nodes that support the corresponding service for the service request, that is, the node 3 can be an entry node or an edge node in other domains.

[0115] Step 405: The network node sends the information of node 3 to the user equipment through node 1 of domain 1, so that the user equipment can directly initiate a service request to node 3.

[0116] Example 3

[0117] This example is a service deployment example. Figure 6 Schematic diagram of the interactive process of the service scheduling method according to an embodiment of the present invention Figure 3 ;like Figure 6 As shown, the method includes:

[0118] Step 501: User equipment sends a service request to a nearby node (eg, node 1 in domain 1).

[0119] Step 502: Node 1 of domain 1 queries the computing power information in the notification domain to determine whether there is a node that supports the service corresponding to the service request.

[0120] Step 503: If it is determined that there is no node supporting the service corresponding to the service request, send the service request to the network device.

[0121] Step 504: The network device monitors the number of service requests for the service, and when the number of service requests reaches a preset threshold, determines a node in domain 1 and / or domain 2, and sends a deployment instruction of the service to the node.

[0122] In this example, dynamic service deployment based on user service requests can be considered. Building on Example 2, when a user's service request cannot be met within the notification domain, it is reported to the network device. The network device maintains relevant records of such service requests. For example, it can maintain the number of service requests within a certain notification domain within a certain time range. When the number of service requests reaches a preset threshold, indicating that the number of service scheduling requests for this service within the notification domain is high and the existing service deployment cannot meet the demand, the network device can then deploy the corresponding service within the notification domain.
