Description

Technical Field

[0001] The present invention relates to the field of computing power network and mobile communication technology, and specifically to a method, device and medium for integrating network active detection and computing power perception. Background Art

[0002] Relying on high-speed, mobile, secure and ubiquitous network connections, the computing network integrates multi-level computing resources such as network, cloud, data, intelligence, edge, end and chain, and combines various emerging digital technologies such as AI, blockchain, cloud, big data and edge computing to provide a new type of information infrastructure with integrated services such as data perception, transmission, storage and computing.

[0003] A computing network is a network form that uses distributed computing power to complete specific tasks. Its core idea is to disperse large-scale computing needs to a large number of participants, and to complete tasks efficiently and quickly through resource sharing and collaborative computing.

[0004] In the computing network field, computing power information and network information are usually transmitted independently, but the independent transmission method has the problem of inconsistent computing network information and low transmission efficiency. Another aggregated transmission method is to aggregate the two types of information together in the routing protocol for notification, but the aggregated transmission method has the problem of inconsistency between the network information in the notification and the network status of the actual forwarding path, and it is still necessary to detect and perceive the network status on the actual forwarding path.

[0005] Therefore, how to obtain computing power information that is consistent with network information when perceiving computing network information, improve the consistency of computing network information, and improve the efficiency of computing network information dissemination is a technical problem that needs to be solved urgently. Summary of the invention

[0006] The technical task of the present invention is to provide a method, device and medium for integrating network active detection and computing power perception to solve the problem of how to obtain computing power information consistent with network information when perceiving computing network information, improve the consistency of computing network information, and improve the efficiency of computing network information dissemination.

[0007] The technical task of the present invention is achieved in the following way: a method for integrating network active detection and computing power perception, the method is as follows:

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

[0009] The edge computing power information database (Computing DB) is maintained in the egress node, and the computing power information requested by the ingress node searches the edge computing power information database;

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

[0011] The egress node updates the edge computing power information database and notifies the ingress node through independent messages or network-aware messages;

[0012] The performance measurement of the actual traffic in one direction is performed between the ingress node and the egress node through the IPPM (IP Performance Measurement) or IFIT (In-situ Flow Information Telemetry) protocol.

[0013] As a preferred embodiment, the computing power information requested by the entry node searches the edge computing power information database 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, a response is returned directly;

[0015] If the computing power information requested by the entry node is not found in the edge computing power information database, the exit node will subscribe to the computing power service and bring back the computing power information in the registration response;

[0016] 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 for computing power and bring back the computing power information in the query response.

[0017] Preferably, computing power related information is carried by extending an independent protocol message or a stream extension header in IPPM or IFIT.

[0018] As a preference, the entry node queries multiple computing power information in batches to avoid excessive impact on IPPM / IFIT or active detection messages;

[0019] When there are too many extended bytes, resulting in fragmentation, the size of the packet is evaluated, and the information to be carried is evenly distributed in the normal data packet, that is, the measurement frequency and the expansion amplitude of the message are balanced; among them, too many extended bytes refer to the expansion of a single message exceeding the set threshold; the expansion of a single data packet should not exceed the set threshold to avoid affecting the forwarding of normal business messages; data packets smaller than 256 bytes are expanded;

[0020] For a data packet, if there is much information to be extended, when extending a data packet will result in the corresponding data packet being fragmented, the extended information is segmented and inserted into multiple data packets to balance the measurement frequency and the expansion amplitude of the message.

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

[0022] A fusion system of active network detection and computing power perception, the system includes an entry node, an exit node and a computing power service, the entry node initiates a network detection request and carries computing power information at the same time; the exit node queries a local computing power database and obtains corresponding query results; when the computing power state changes, the computing power data will be actively notified to reach the entry node through the exit node; the one-way IPPM or IFIT network quality perception from the entry node to the exit node is extended to carry computing power information query requests, and the one-way IPPM or IFIT network quality perception 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 the local computing power database, as follows:

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

[0025] If the exit node fails to find the local computing power database, it subscribes to 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 queries the local computing power database but the data is 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 perception protocol, and carries computing power related information in the extension; wherein the extended network perception protocol includes extensions of active detection protocol, passive perception, IFIT or IPPM flow perception and hybrid perception protocol;

[0028] Maintain an edge computing power information database at the exit node, which senses and obtains edge computing power information and responds to inquiries from the entry node or actively notifies the entry node.

[0029] At the entry node, query the various computing power information that needs to be perceived in batches, balance the measurement frequency and the expansion range of the message, and avoid excessive impact on IPPM, IFIT or active detection messages.

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

[0031] Wherein, the memory stores a computer program;

[0032] The at least one processor executes the computer program stored in the memory, so that the at least one processor performs the above-mentioned method of integrating network active detection and computing power perception.

[0033] A computer-readable storage medium stores a computer program, which can be executed by a processor to implement the above-mentioned method of integrating network active detection and computing power perception.

[0035] (1) The present invention is based on the protocol extension of the network active detection technology or the flow detection technology, and carries the computing power related parameters and information in the extended field of the message or encapsulation;

[0036] (ii) The present invention obtains computing power information consistent with the network information while sensing the network information on the forwarding path, and the computing power information is more consistent;

[0037] (III) The present invention reduces the types of computing network perception protocols used by extending the network perception protocol 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 the present invention is used for computing network information perception, computing power information consistent with network information is obtained, the computing network information consistency is higher, the types of computing network perception protocols used are reduced, the complexity of the host protocol stack is reduced, the network resource consumption is reduced, and the computing network information transmission efficiency is higher;

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