Description

Technical Field

[0001] The present invention relates to the field of mobile computing network technology, and in particular to a real-time perception method for endogenous computing resources of a mobile computing network. Background Art

[0002] The computing network introduces computing information into network data forwarding. By perceiving the user's business needs, computing resources and network resources, it dynamically selects the "forwarding path + destination service node" that meets the business needs, and schedules the service node along the specified path, thereby achieving global optimization of computing power and network resources. The computing task scheduling of the computing network considers the availability, computing power, load of each computing node, as well as the priority and resource requirements of the task, assigns the computing task to the appropriate computing node, and builds the optimal network forwarding path between the computing task and the computing node based on the computing node and network topology information to ensure that the task can be processed at the fastest speed. The computing task scheduling algorithm of the computing network is based on the computing power information of the computing nodes in the computing network. The computing power information includes the computing power type (such as CPU, GPU, NPU, etc.), computing power computing capacity (such as TOPS, TFLOPS, etc.), and computing power node load (such as CPU load, GPU load, etc.).

[0003] In the diagram of the network communication architecture, the mobile communication network is designed to connect mobile users with fixed-point users (or between mobile users) to achieve voice and data communication. The network consists of three main components: wireless devices, transmission devices, and core network devices. Wireless devices, including user terminals (such as smartphones and tablets) and base stations, are responsible for managing and scheduling wireless channel resources to ensure that data can be efficiently forwarded through wireless channels while meeting mobility requirements, which means that users can maintain continuous network connections no matter where they are. Transmission devices are responsible for transmitting fixed-line data between wireless base stations and core network devices to ensure that data can flow stably and reliably between different network nodes, thereby supporting large-scale data transmission requirements. Core network devices are the brains of the mobile communication network, responsible for managing key control functions such as wireless base station connections, user terminal access control, registration, session establishment, and mobility management; in addition, core network devices also handle data forwarding between user terminals and external data networks (such as the Internet) to ensure that users can seamlessly access network resources and services.

[0004] The Mobile Computing Network is based on the mobile communication network that provides connection services, combined with the ubiquitous endogenous computing power (terminal computing power, base station computing power, core network edge computing power and other computing power resources) in the mobile communication network, and through management and control mechanisms to coordinate connection resources and computing power resources, so as to achieve on-demand computing services. The Mobile Computing Network is a dual infrastructure of connection + computing, and is the evolution of the computing network in the mobile communication network.

[0005] Accurate and real-time scheduling of computing tasks in mobile computing networks requires real-time perception of computing power changes. The polling query or subscription notification event acquisition mechanism in existing mobile communication networks has the defects of time-consuming connection establishment, cumbersome interactive messages, and point-to-point communication, which cannot achieve real-time perception of the computing power resources of the entire network by mobile computing network scheduling. Summary of the invention

[0006] Aiming at the problem that the polling query or subscription notification event acquisition mechanism in the existing mobile communication network cannot achieve the real-time perception of the computing power resources of the entire network by the mobile computing power network scheduling, the present invention provides a real-time perception method for the endogenous computing power resources of the mobile computing power network.

[0007] The present invention provides a method for real-time perception of endogenous computing power resources in a mobile computing power network, and the technical solution adopted to solve the above technical problems is as follows:

[0008] A real-time perception method for endogenous computing power resources in a mobile computing power network, the method relying on a computing power perception bus and perception data notification, wherein:

[0009] The computing power perception bus is responsible for managing and distributing the information of computing power nodes in the mobile communication network. The computing power perception bus provides two services for the service provider: computing power information subscription and computing power information de-subscription. The computing power information subscription service allows the service provider or management node in the network to subscribe to the specified computing power node information, and the computing power information de-subscription service allows the node that has subscribed to the computing power information to actively stop receiving data and status information related to the specified computing power node;

[0010] The perception data notification is responsible for distributing computing power perception data. The perception data notification is transmitted in a connectionless manner, supports a hybrid mode of unicast, multicast and broadcast, and is sent with low latency to ensure fast and efficient data processing.

[0011] Optionally, the computing power-aware bus itself is implemented using a service-based SBA or a message queue.

[0012] Optionally, the computing power perception bus involved includes three parts: a computing power registration center, a computing power information provider, and a computing power information consumer, among which:

[0013] The computing power registration center is the central node for computing power registration and management of the mobile computing power network. In the mobile computing power network, all computing power nodes need to be initially registered at the computing power registration center, and the computing power registration center maintains a database or directory to record the current status and capabilities of all registered nodes;

[0014] The computing power information provider is a node that provides computing power resources in the mobile computing power network. The computing power information provider registers its own resources through the computing power registration center and updates the status information of the resources in real time.

[0015] The computing power information consumer is a node that needs to use computing power resources. The computing power information consumer queries the available computing power resources through the computing power registration center and finds the computing power information provider that can meet its needs. Once the computing power information provider that meets its needs is found, the computing power information consumer subscribes to the computing power information change request to obtain the latest status and changes of the computing power resources in real time.

[0016] Further optional, the computing power subscription process based on the computing power perception bus is described as follows:

[0017] (A1) Registration of computing power information provider: The computing power information provider, i.e., the computing power node of the mobile computing power network, notifies the computing power registration center of its initial computing power information, including computing power node identification, computing power node type, computing power node network address, computing power node service port number, computing power notification multicast address, computing power notification multicast port, computing power notification broadcast address, and computing power notification broadcast port;

[0018] (A2) Querying computing power information: The computing power information consumer queries the computing power registration center for information about the computing power information provider, including the computing power node identifier, computing power node type, computing power node network address, and computing power node service port number;

[0019] (A3) Subscription to computing power information changes: The computing power message consumer sends a computing power information change subscription message to the computing power information provider, and the computing power information provider stores the computing power information change subscription list locally; wherein, the computing power information change subscription message includes a notification mode, a notification number, a notification period, a notification range, a unicast notification address, and a unicast notification port number: the notification mode is divided into three types: single notification, multiple notifications, and periodic notification. (a1) When the notification mode is single notification or multiple notifications, the notification number indicates the number of times the computing power information needs to be notified after the computing power information changes. (a2) When the notification mode is periodic notification, the notification period indicates the notification period in seconds. The notification range is divided into unicast, multicast, and broadcast. (b1) Unicast indicates that the notification range is a unique computing power subscriber. (b2) Multicast indicates that the notification range is multiple computing power subscribers with the same multicast IP address. (b3) Broadcast indicates that the notification range is multiple computing power subscribers with the same network domain broadcast IP address.

[0020] Further optional, the computing power subscription process based on the computing power perception bus is described as follows:

[0021] (B1) Initiate a desubscription request: When the computing power information consumer decides not to receive information from one or more computing power nodes, it initiates a desubscription request to the computing power registration center. This request will specify the identifier of the computing power node that needs to be unsubscribed and related information;

[0022] (B2) Processing the unsubscribe request: After receiving the unsubscribe request, the computing power registration center updates the computing power information consumer information in its database or directory and removes the subscription relationship with the specified computing power node;

[0023] (B3) Notify the computing power information provider: Once the unsubscription request is processed, the computing power registration center will notify the relevant computing power information provider, informing its computing power information consumer that it no longer needs to receive its computing power information updates;

[0024] (B4) After receiving the unsubscription notification, the computing power information provider updates its locally stored computing power information change subscription list to ensure that it no longer sends information to the computing power information consumer that has unsubscribed;

[0025] (B5) Confirmation and feedback: After the entire unsubscription process is completed, the computing power registration center sends a confirmation message to the computing power information consumer to inform that the unsubscription operation has been successfully executed.

[0026] Further optionally, the computing power perception data notification process based on the perception data notification is described as follows:

[0027] (C1) Trigger conditions:

[0028] (C1.a) If the notification mode in the computing power information change subscription message received by the computing power information provider is periodic notification: when the periodic clock reaches the time when the computing power notification is triggered, the computing power information provider will make a computing power notification;

[0029] (C1.b) If the notification mode in the computing power information change subscription message received by the computing power information provider is single notification or multiple notifications: when the computing power information of the computing power information provider changes, the computing power information provider shall make a computing power notification;

[0030] (C2) Notification sending: The computing power information provider subscribes to the list based on the computing power information changes stored locally and sends the computing power information using the UDP message format;

[0031] (C3) Scope of notification:

[0032] (C3.a) If the notification scope in the subscription information is unicast, the computing power information provider sends a UDP unicast computing power notification message to the specified computing power information consumer;

[0033] (C3.b) If the notification scope in the subscription information is multicast, the computing power information provider sends a UDP multicast computing power information notification to a group of computing power information consumers;

[0034] (C3.c) If the notification scope in the subscription information is broadcast, the computing power information provider sends a UDP broadcast computing power information notification to the computing power information consumer in the same network domain;

[0035] (C4) The computing power information provider determines the subsequent actions based on the notification mode in the local query computing power information change subscription list:

[0036] (C4.a) If the notification mode is single notification, when the number of notifications of computing power information reaches the upper limit, the computing power information provider will no longer make subsequent notifications;

[0037] (C4.b) If the notification mode is multiple notifications, when the number of notifications of the computing power information does not reach the upper limit and the computing power information changes again, the computing power information provider will notify according to the set notification conditions;

[0038] (C4.c) If the notification mode is periodic notification, the notification continues according to the set period.

[0039] Compared with the prior art, the real-time perception method of the endogenous computing power resources of a mobile computing power network of the present invention has the following beneficial effects:

[0040] Through the two mechanisms of computing power perception bus and perception data notification, the present invention enables the mobile computing power network to perceive and adapt to changes in endogenous computing power resources in real time, which makes the network more intelligent and adaptive, optimizes resource utilization, improves overall performance and efficiency, and solves the problem that the polling query or subscription notification event acquisition mechanism in the existing mobile communication network cannot achieve real-time perception of the computing power resources of the entire network by the mobile computing power network scheduling; real-time computing power perception is crucial to supporting computing-intensive tasks and services, especially in dynamically changing network environments.

[0042] Attached Figure 2 This is a flowchart of computing power subscription based on a computing power sensing bus in the first embodiment of the present invention. DETAILED DESCRIPTION

[0043] In order to make the technical solution, the technical problem solved and the technical effect of the present invention more clearly understood, the technical solution of the present invention is clearly and completely described below in conjunction with specific embodiments.

[0044] Embodiment 1:

[0045] This embodiment proposes a real-time perception method of endogenous computing power resources in a mobile computing power network. The method relies on a computing power perception bus and perception data notification, wherein:

[0046] The computing power perception bus is responsible for managing and distributing the information of computing power nodes in the mobile communication network. The computing power perception bus provides two services for the service provider: computing power information subscription and computing power information de-subscription. The computing power information subscription service allows the service provider or management node in the network to subscribe to the specified computing power node information, and the computing power information de-subscription service allows the node that has subscribed to the computing power information to actively stop receiving data and status information related to the specified computing power node;

[0047] The perception data notification is responsible for distributing computing power perception data. The perception data notification is transmitted in a connectionless manner, supports a hybrid mode of unicast, multicast and broadcast, and is sent with low latency to ensure fast and efficient data processing.

[0048] In this embodiment, the computing power perception bus itself is implemented using a service-based SBA (Service-Based Architecture) or a message queue.

[0049] The computing power perception bus consists of three parts: computing power registration center, computing power information provider and computing power information consumer.

[0050] The computing power registration center is the central node for computing power registration and management of the mobile computing power network. In the mobile computing power network, all computing power nodes (such as core network functions, base stations, terminals, etc.) need to be initially registered at the computing power registration center. This process is similar to a node introducing itself to the network and providing detailed information about its computing power resources, such as processing power, storage capacity, and network bandwidth. The computing power registration center maintains a database or directory to record the current status and capabilities of all registered nodes.

[0051] The computing power information provider is a node that provides computing power resources in the mobile computing power network. The computing power information provider registers its own resources through the computing power registration center and updates the status information of the resources in real time.

[0052] The computing power information consumer is a node that needs to use computing power resources. The computing power information consumer queries the available computing power resources through the computing power registration center and finds the computing power information provider that can meet its needs. Once the computing power information provider that meets its needs is found, the computing power information consumer subscribes to the computing power information change request to obtain the latest status and changes of the computing power resources in real time.

[0053] (A) Combined with Figure 1 ,The computing power subscription process based on the computing power perception bus is described as follows:

[0054] (A1) Registration of computing power information providers: The computing power information provider, i.e., the computing power node of the mobile computing power network, notifies the computing power registration center of its initial computing power information, including the computing power node identifier, computing power node type (e.g., CPU, GPU, etc.), computing power node network address, computing power node service port number, computing power notification multicast address, computing power notification multicast port, computing power notification broadcast address, and computing power notification broadcast port;

[0055] (A2) Query of computing power information: The computing power information consumer queries the computing power registration center for information about the computing power information provider, including the computing power node identifier, computing power node type (e.g., CPU, GPU, etc.), computing power node network address, and computing power node service port number;

[0056] (A3) Subscription to computing power information changes: The computing power message consumer sends a computing power information change subscription message to the computing power information provider, and the computing power information provider stores the computing power information change subscription list locally; wherein, the computing power information change subscription message includes a notification mode, a notification number, a notification period, a notification range, a unicast notification address, and a unicast notification port number: the notification mode is divided into three types: single notification, multiple notifications, and periodic notification. (a1) When the notification mode is single notification or multiple notifications, the notification number indicates the number of times the computing power information needs to be notified after the computing power information changes. (a2) When the notification mode is periodic notification, the notification period indicates the notification period in seconds. The notification range is divided into unicast, multicast, and broadcast. (b1) Unicast indicates that the notification range is a unique computing power subscriber. (b2) Multicast indicates that the notification range is multiple computing power subscribers with the same multicast IP address. (b3) Broadcast indicates that the notification range is multiple computing power subscribers with the same network domain broadcast IP address.

[0057] (B) Combined with Figure 2 ,The computing power subscription process based on the computing power perception bus is described as follows:

[0058] (B1) Initiate a desubscription request: When the computing power information consumer (i.e., subscriber) decides not to receive information from one or some computing power nodes, it initiates a desubscription request to the computing power registration center. This request will specify the identifier of the computing power node that needs to be unsubscribed and related information;

[0059] (B2) Processing unsubscription requests: After receiving the unsubscription request, the computing power registration center updates the information of the computing power information consumer (i.e., subscriber) in its database or directory and removes the subscription relationship with the specified computing power node. This may include deleting the identifier of the computing power information consumer (i.e., subscriber) and canceling the previous subscription settings.

[0060] (B3) Notify the computing power information provider: Once the unsubscription request is processed, the computing power registration center will notify the relevant computing power information provider (i.e., the subscribed computing power node) to inform its computing power information consumer (i.e., subscriber) that it no longer needs to receive its computing power information updates;

[0061] (B4) After receiving the unsubscribe notification, the computing power information provider (i.e., the subscribed computing power node) updates its locally stored computing power information change subscription list to ensure that it no longer sends information to the computing power information consumer that has unsubscribed;

[0062] (B5) Confirmation and feedback: After the entire unsubscription process is completed, the computing power registration center sends a confirmation message to the computing power information consumer to inform that the unsubscription operation has been successfully executed; at the same time, if any problems are encountered during the unsubscription process, the subscriber will be notified in a timely manner through the feedback mechanism.

[0063] (C) The computing power perception data notification process based on perception data notification is described as follows:

[0064] (C1) Trigger conditions:

[0065] (C1.a) If the notification mode in the computing power information change subscription message received by the computing power information provider is periodic notification: when the periodic clock reaches the time when the computing power notification is triggered, the computing power information provider will make a computing power notification;

[0066] (C1.b) If the notification mode in the computing power information change subscription message received by the computing power information provider is single notification or multiple notifications: when the computing power information of the computing power information provider changes (such as CPU utilization, GPU utilization, number of computing power tasks, etc.), the computing power information provider will make a computing power notification;

[0067] (C2) Notification sending: The computing power information provider uses the UDP message format to send computing power information according to the subscription list of computing power information changes stored locally. The computing power information adopts the UDP message format, including the computing power node identification, computing power node type (such as CPU, GPU, etc.), computing power load and computing power value (such as FLOPS floating point operations per second, TOPS trillion operations per second, etc.);

[0068] (C3) Scope of notification:

[0069] (C3.a) If the notification scope in the subscription information is unicast, the computing power information provider sends a UDP unicast computing power notification message to the specified computing power information consumer according to the unicast notification address and unicast notification port number in the subscription computing power information change notification;

[0070] (C3.b) If the notification scope in the subscription information is multicast, the computing power information provider sends a UDP multicast computing power information notification to a group of computing power information consumers according to the computing power notification multicast address and computing power notification multicast port in the notification initial computing power information;

[0071] (C3.c) If the notification scope in the subscription information is broadcast, the computing power information provider sends a UDP broadcast computing power information notification to the computing power information consumers in the same network domain according to the computing power notification broadcast address and computing power notification broadcast port in the notification initial computing power information;

[0072] (C4) The computing power information provider determines the subsequent actions based on the notification mode in the local query computing power information change subscription list:

[0073] (C4.a) If the notification mode is single notification, when the number of notifications of computing power information reaches the upper limit, the computing power information provider will no longer make subsequent notifications;

[0074] (C4.b) If the notification mode is multiple notifications, when the number of notifications of the computing power information does not reach the upper limit and the computing power information changes again, the computing power information provider will notify according to the set notification conditions;

[0075] (C4.c) If the notification mode is periodic notification, the notification continues according to the set period.

[0076] In summary, the real-time perception method of the endogenous computing power resources of a mobile computing power network of the present invention can perceive and adapt to the changes of the endogenous computing power resources in real time, and solve the problem that the polling query or subscription notification event acquisition mechanism in the existing mobile communication network cannot achieve the real-time perception of the computing power resources of the entire network by the mobile computing power network scheduling.
