Description

Technical Field

[0001] This invention relates to the fields of computing power networks and mobile communication technology, specifically to a method, device, and medium for integrating network active detection and computing power perception. Background Technology

[0002] The computing power network relies on high-speed, mobile, secure, and ubiquitous network connectivity to integrate multi-level computing power resources such as network, cloud, data, intelligence, edge, terminal, and blockchain. It also combines various emerging digital technologies such as AI, blockchain, cloud, big data, and edge computing to provide a new type of information infrastructure that integrates data perception, transmission, storage, and computing services.

[0003] A computing network is a network architecture that utilizes distributed computing power to complete specific tasks. Its core idea is to distribute large-scale computing demands among numerous participants, and achieve efficient and rapid task completion through resource sharing and collaborative computing.

[0004] In the field of computing power networks, computing power information and network information are usually propagated independently. However, this independent propagation method suffers from inconsistencies between computing power and network information and low transmission efficiency. Another method is aggregation propagation, which combines the two types of information in the routing protocol for announcement. However, this aggregation propagation method suffers from inconsistencies between the network information in the announcement and the actual network status of the forwarding path. Therefore, network status detection and awareness are still required on the actual forwarding path.

[0005] Therefore, how to obtain computing power information that is consistent with network information during the perception of computing network information, improve the consistency of computing network information, and improve the efficiency of computing network information dissemination are technical problems that urgently need to be solved. Summary of the Invention

[0006] The technical objective of this invention is to provide a method, device, and medium for fusing network active detection and computing power perception, in order to solve the problem of how to obtain computing power information that is consistent with network information during network information perception, thereby improving the consistency of network information and the efficiency of network information dissemination.

[0007] The technical objective of this invention is achieved as follows: a method for fusing network active detection and computing power awareness, the specific method of which is as follows:

[0008] In the computing power network scenario, computing power information is carried through protocol extensions in the network active probing request and response: the entry node sends a computing power query request to the exit node, and the exit node replies to the entry node with the computing power query result;

[0009] The egress node maintains an edge computing power information database (Computing DB), and the ingress node searches the edge computing power information database for requested computing power information;

[0010] When the computing power service information changes and the change exceeds the set threshold, the exit node is notified.

[0011] The exit node updates the edge computing power information database and notifies the inbound node through a separate message or a network-aware message.

[0012] The performance of unidirectional actual traffic is measured between the ingress and egress nodes via IPPM (IP Performance Measurement) or IFIT (In-situ Flow Information Telemetry) protocols.

[0013] As a preferred approach, the process of searching the edge computing power information database for the computing power information requested by the entry node is as follows:

[0014] If the computing power information requested by the entry node is found in the edge computing power information database normally and the computing power data is obtained within the set time range, then a response is returned directly;

[0015] If the computing power information requested by the ingress node cannot be found in the edge computing power information database, the egress node will subscribe to and register with the computing power service and bring back the computing power information in the registration response.

[0016] If the computing power information requested by the ingress node is found in the edge computing power information database, but the computing power data update time exceeds the set time range, the egress node will query the computing power service and bring back the computing power information in the query response.

[0017] Preferably, computing power-related information is carried by extending the independent protocol messages or the following extension header in IPPM or IFIT.

[0018] As a preferred approach, the entry node queries various computing power information in batches to avoid excessive impact on IPPM / IFIT or proactive probe messages;

[0019] When excessive extension bytes lead to fragmentation, the packet size is evaluated, and the information to be carried is evenly distributed among normal data packets, thus balancing the measurement frequency and the packet extension range. Excessive extension bytes refer to extending a single packet beyond a set threshold. The extension of a single data packet should not exceed the set threshold to avoid affecting the forwarding of normal service packets. Small data packets smaller than 256 bytes should be extended.

[0020] If a data packet requires a lot of expanded information, expanding the data packet will cause the expanded information to be segmented and inserted into multiple data packets when the corresponding data packet is fragmented, in order to balance the measurement frequency and the expansion range of the message.

[0021] Even better, during network probing, intermediate nodes are set up to record network quality, such as through source routing technology, without affecting the expansion of computing power information.

[0022] A fusion system of network active detection and computing power awareness is disclosed. The system includes an entry node, an exit node, and computing power services. The entry node initiates a network detection request, carrying computing power information. The exit node queries the local computing power database and obtains the corresponding query results. When the computing power status changes, it actively sends computing power data notifications, which reach the entry node through the exit node. One-way IPPM or IFIT network quality awareness from the entry node to the exit node is extended to carry computing power information query requests, and one-way IPPM or IFIT network quality awareness from the exit node to the entry node is extended to carry computing power information data.

[0023] As a preferred option, the exit node queries its local computing power database, and the results are as follows:

[0024] If the exit node finds the local computing power database, the exit node returns a response to the entry node, carrying the relevant computing power information data;

[0025] If the exit node cannot find the local computing power database, it subscribes to computing power information from the computing power service and carries the computing power information in the computing power subscription response. The exit node returns a response to the entry node, carrying the relevant computing power information data.

[0026] If the exit node finds the local computing power database but the data has expired, the exit node sends a query request to the computing power service, and the computing power service returns a query response to the exit node.

[0027] Preferably, the system extends the network sensing protocol, carrying computing power-related information in the extension; the extended network sensing protocol includes extensions of active detection protocol, passive sensing, IFIT or IPPM flow sensing and hybrid sensing protocol.

[0028] The edge computing power information database is maintained at the exit node. The exit node senses and obtains the edge computing power information and responds when the entry node queries it, or actively notifies the entry node.

[0029] At the entry node, various computing power information that needs to be sensed are queried in batches to balance the frequency of measurement and the expansion range of messages, so as to avoid excessive impact on IPPM, IFIT or active probe messages.

[0030] An electronic device includes: a memory and at least one processor;

[0031] The memory contains computer programs;

[0032] The at least one processor executes the computer program stored in the memory, causing the at least one processor to perform the network active detection and computing power perception fusion method as described above.

[0033] A computer-readable storage medium storing a computer program that can be executed by a processor to implement the network active detection and computing power perception fusion method as described above.

[0034] The method, device, and medium for fusing network active detection and computing power perception of the present invention have the following advantages:

[0035] (i) This invention is based on the protocol extension of network active detection technology or flow detection technology, and carries computing power related parameters and information in the extended fields of the message or encapsulation;

[0036] (ii) While sensing network information on the forwarding path, this invention also obtains computing power information that matches the network information, resulting in higher consistency between computing and network information.

[0037] (III) This invention reduces the types of computing network sensing protocols used by extending network sensing protocols to carry computing power information, reduces the complexity of the host protocol stack, reduces network resource consumption, and improves the efficiency of computing network information transmission.

[0038] (iv) When using the present invention for network information perception, computing power information that matches network information is obtained, network information consistency is higher, the types of network perception protocols used are reduced, the complexity of the host protocol stack is reduced, network resource consumption is reduced, and network information transmission efficiency is higher.

[0039] (v) The computing power and network information obtained by this invention are highly consistent, and the technical complexity is reduced by reducing the independent computing power perception process, reducing the overhead of network protocols, host protocol stacks and network bandwidth.

[0040] The invention will be further described below with reference to the accompanying drawings.

[0041] Appendix Figure 1 This is a schematic diagram of a method that integrates network active detection and computing power awareness. Detailed Implementation

[0042] The following detailed description of the network active detection and computing power perception fusion method, device and medium of the present invention is provided with reference to the accompanying drawings and specific embodiments.

[0043] Example 1:

[0044] As attached Figure 1As shown in the figure, this embodiment provides a method for fusing network active detection and computing power awareness, which is as follows:

[0045] (1) In the computing power network scenario, computing power information is carried through protocol extension in the network active probing request and response: the entry node sends a computing power query request to the exit node, and the exit node replies to the entry node with the computing power query result;

[0046] (2) The edge computing power information database (Computing DB) is maintained in the exit node, and the computing power information requested by the entry node is searched in the edge computing power information database;

[0047] (3) When the computing power service information changes and the change exceeds the set threshold, notify the exit node;

[0048] (4) The exit node updates the edge computing power information database and notifies the inbound node through independent messages or network-aware messages.

[0049] (5) The performance of the actual flow between the ingress node and the egress node is measured in one direction via IPPM (IP Performance Measurement) or IFIT (In-situ Flow Information Telemetry) protocol.

[0050] In this embodiment, step (2) involves the entry node requesting computing power information to search the edge computing power information database as follows:

[0051] ① If the computing power information requested by the entry node is found in the edge computing power information database normally and the computing power data is obtained within the set time range, then the response is returned directly;

[0052] ② If the computing power information requested by the entry node cannot be found in the edge computing power information database, the exit node shall subscribe to and register with the computing power service and bring back the computing power information in the registration response;

[0053] ③ If the computing power information requested by the entry node is found in the edge computing power information database, but the computing power data update time exceeds the set time range, the exit node will query the computing power service and bring back the computing power information in the query response.

[0054] In this embodiment, computing power-related information is carried by extending the independent protocol messages or the following extension header in IPPM or IFIT.

[0055] In this embodiment, the entry node queries various computing power information in batches to avoid excessive impact on IPPM / IFIT or active probe messages;

[0056] When excessive extension bytes lead to fragmentation, the packet size is evaluated, and the information to be carried is evenly distributed among normal data packets, thus balancing the measurement frequency and the packet extension range. Excessive extension bytes refer to extending a single packet beyond a set threshold. The extension of a single data packet should not exceed the set threshold to avoid affecting the forwarding of normal service packets. Small data packets smaller than 256 bytes should be extended.

[0057] If a data packet requires a lot of expanded information, expanding the data packet will cause the expanded information to be segmented and inserted into multiple data packets when the corresponding data packet is fragmented, in order to balance the measurement frequency and the expansion range of the message.

[0058] In this embodiment, during the network detection process, intermediate nodes are set up to record network quality, such as through source routing technology, without affecting the expansion of computing power information.

[0060] This embodiment provides a fusion system of proactive network detection and computing power awareness. The system includes an entry node, an exit node, and computing power services. The entry node initiates a network detection request, carrying computing power information. The exit node queries the local computing power database and obtains the corresponding query results. When the computing power status changes, it will proactively send computing power data notifications, which will reach the entry node through the exit node. One-way IPPM or IFIT network quality awareness from the entry node to the exit node is extended to carry computing power information query requests, and one-way IPPM or IFIT network quality awareness from the exit node to the entry node is extended to carry computing power information data.

[0061] In this embodiment, the exit node queries the local computing power database as follows:

[0062] ① If the exit node finds the local computing power database, the exit node returns a response to the entry node, carrying the relevant computing power information data;

[0063] ② If the exit node cannot find the local computing power database, it subscribes to computing power information from the computing power service and carries the computing power information in the computing power subscription response. The exit node returns a response to the entry node, carrying the relevant computing power information data.

[0064] ③ If the exit node finds the local computing power database but the data has expired, the exit node sends a query request to the computing power service, and the computing power service returns a query response to the exit node.

[0066] The edge computing power information database is maintained at the exit node. The exit node senses and obtains the edge computing power information and responds when the entry node queries it, or actively notifies the entry node.

[0067] At the entry node, various computing power information that needs to be sensed are queried in batches to balance the frequency of measurement and the expansion range of messages, so as to avoid excessive impact on IPPM, IFIT or active probe messages.

[0068] 1. The entry node initiates a network probe request, carrying computing power information at the same time;

[0069] 2. The export node queries the local computing power database. If the query is successful, proceed to step 5.

[0070] 3. If the query fails, proceed to steps 3a and 3b to subscribe to computing power information from the computing power service and include the computing power information in the computing power subscription response. Then proceed to step 5.

[0071] 4. The export node queries the local computing power database. If the query is successful but the data is expired, proceed to steps 4a and 4b, and then jump to step 5.

[0072] 5. The exit node returns a response to the entry node, carrying relevant computing power information data;

[0073] 6. When the computing power status changes, computing power data will be proactively notified and transmitted to the entry node through the exit node;
