and acquiring the numerical values of the evaluation items corresponding to the service providers of all the available services in a local routing table, wherein the numerical values of the evaluation items corresponding to the service providers are recorded in the local routing table.
A routing table refers to a table of routing information stored on a router or other internet network device that stores paths to a particular network terminal and, in some cases, metrics associated with those paths. The local routing table is a collection table of all network segments connected with the local routing table by using a protocol, and indicates the transmission direction of local data and data passing through a computer. And after determining the evaluation items corresponding to the service requests and acquiring the numerical values of the evaluation items corresponding to the service providers of all the available services, recording the numerical values of the evaluation items corresponding to the service providers of all the available services in the local routing table, so that the service providers of all the available services can acquire the numerical values conveniently at any time.
Further, the numerical values of the evaluation items are updated periodically, and the updated information is updated to the local routing table.
If more task requests are processed by the service provider with the optimal service quality, the processing speed of the service provider is reduced, the numerical value of the evaluation item is also reduced, and when the service provider with the optimal service quality is refreshed to the combination with the highest score, the task request is received and sent to the service provider with the optimal service quality.

the evaluation model is summation operation;
correspondingly, when the service request comprises service classification information of an object identification class, the service quality is the sum of the calculation time, the identification accuracy, the classification confidence and the transmission time.
If the service classification information contained in the service request is not considered, the evaluation item only considers the calculation time of the service provider and the transmission time of the service request from the route to the service provider; the quality of service is the sum of the calculation time and the transmission time.
Preferably, the evaluation model is a reinforcement learning model.
The algorithm for selecting the service provider selects an algorithm for the service provider.
Further, the reinforcement learning model includes a weight value of each evaluation item, and a preset evaluation model is adopted to calculate a numerical value of the evaluation item corresponding to each service provider to obtain the service quality of each service provider, including:
and performing weighted operation on the numerical values of the evaluation items according to the weight values to obtain the service quality of each service provider.
In this embodiment, the algorithm for reinforcement learning is applied to the field of selection algorithm of the service provider, specifically,
first, a plurality of evaluation items are listed for the service request according to the characteristics of the service request. Taking object recognition as an example, the evaluation items include: calculating time, object recognition accuracy, classification confidence and the like.
The training method is deployed at a terminal, and software of the training algorithm exists as a background service or as a module integrated in client codes.
The content of the training is to learn how to balance the advantages and disadvantages in factors such as calculation time, object recognition accuracy rate and classification confidence "
The implementation method is that all the characteristics (calculation time, object recognition accuracy and classification confidence) are scored, and the person with the highest score is selected.
Setting the values of the parameters P1, P2 and P3 between 0 and 1, so that P1+ P2+ P3=1,
total Score = Score1 × P1+ Score2 × P2+ Score3 × P3.
The specific action of training is to continuously adjust the values of P1, P2 and P3 according to the practical result. The value of the evaluation item of the service request is made higher. Therefore, the value of the evaluation item corresponding to the service request of each service provider is improved.
In some embodiments, the intelligent routing method, the service provider is located in one or more of:
the system comprises a terminal local, a local area network server and a cloud server.
Deployment of service providers is based on real-time.
Real-time is a factor that first needs attention in a particular application considering where the service provider is deployed to run. Each specific application scenario has its determined real-time requirements. Various deployment scenarios have the highest real-time performance that it can achieve. Unreasonable deployment schemes will make the product unable to work effectively.
The intelligent service and the traditional service are distinguished by the following points: the intelligent service also has the requirement of being deployed in the local, and many clients can smoothly transfer to the local resource to obtain the service when the clients cannot be supported by the server. Therefore, the inventor deploys the service provider locally on the terminal through a large amount of work, so that each smart technology platform can locally invoke the service of the service provider by the terminal.
The terminal executes locally, corresponding to the highest response speed, possibly up to the order of 1 millisecond, requiring the task request to be executed in the core of the device digital system (in the embedded system), for example a task request generated by a mechanical device controlled by the embedded system, to be completed by a service provider running in the embedded system.
The task request is transmitted to a service provider deployed in the local area network through Ethernet and local area network routing, and the service provider uniformly solves the task requests of all the clients in the local area network and returns the task requests to all the clients.
The task request is transmitted to a service provider deployed in the internet, and the service provider uniformly solves the task requests of all clients in the internet and returns the task requests to all the clients.
In addition to real-time, there are many other factors that need to be taken into account. Such as:
energy consumption, many mobile devices are powered by batteries and hope to reach reasonable endurance, and such devices often need to be executed by placing service providers at far ends, namely, a local area network server and a cloud server;
cost, calculation of task requests, hardware acceleration equipment such as a GPU (graphics processing unit) and the like are often required, certain cost is achieved, when products need price competition, if the task requests are solved locally at a terminal, more expensive hardware cost is required, the problem can be solved when the task requests are placed at far ends, namely a local area network server and a cloud server, and real-time performance can be reduced;
similarly, there is a volume issue, with GPU devices having a certain volume; the heat dissipation problem, high frequency calculation, can produce a large amount of heats, is far higher than the calculation heat dissipation of CPU, for airtight, the equipment of silence, need do special design for this reason.
Fig. 2 is an exemplary diagram of an intelligent routing method provided in an embodiment of the present application, and referring to fig. 2, 21,45,51 are all service providers, each having its own service content, and the middle 51 service provider is closer to the rightmost client.
51 can be considered as a service provider within a local area network, 21,45 is a service provider on the internet, 51 has a local service D, but on the routing table it maintains service a and service B of 21 service providers on the internet, 45 service a and service C provided by service provider, and with respect to service a,51 has selected the best service a from 45,
when the client issues a task request a, service a on 45 is found directly 51 here, and service a on 45 is superior to service a local to the client, i.e. the terminal, so the client will choose 45 to provide the service.
In this embodiment, only the calculation time of the service provider for processing the task request and the transmission time of the service request routed to the routing path of the service provider are considered.

a memory 31 for storing a computer program;
a processor 32, connected to the memory 31, is used to run the computer program stored in the memory 31 to perform the method as described above.
