Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.

Fig. 3 is a schematic flowchart of a flow control method for OTA download according to an embodiment of the present invention, and as shown in fig. 3, the method specifically includes:

and S31, monitoring the flow of each service to obtain the service flow corresponding to each service.

In the embodiment of the invention, a service grid organization (service mesh entity) can be adopted to monitor the traffic of all services provided by the system, and obtain the service traffic corresponding to each service, wherein the service traffic can measure the bandwidth occupied by the service, and all services comprise OTA services.

And S32, when the fact that the service flow of the OTA service occupies the available bandwidth amount which is larger than the preset threshold value is monitored, determining a flow control strategy based on the difference value between the service flow of the OTA service and the available bandwidth amount which is occupied by the service flow of the OTA service and the preset threshold value.

And S33, completing the service flow control of the OTA service based on the flow control strategy.

In the embodiment of the invention, the threshold value of the available bandwidth occupied by the service flow of the OTA service for flow control can be preset, and when the threshold value is reached or exceeded, the flow control program is triggered. The flow control can be the communication protocol conversion of other services, so that the bandwidth occupation is reduced, and further more bandwidths and service flows are provided for OTA services.

Optionally, a flow control policy may be determined according to a difference between an available bandwidth amount occupied by service traffic of the OTA service and a preset threshold, where the flow control policy may be to perform communication protocol conversion on one or more services. The target service for performing the communication protocol conversion may also be selected according to a preset rule, and a specific rule is described in detail in the embodiment corresponding to fig. 5.

Further, communication protocol conversion is carried out on the services with the target quantity according to the determined flow control strategy, and more bandwidths and service flows are provided for OTA services.

According to the OTA download flow control method provided by the embodiment of the invention, the flow of each service is monitored to obtain the service flow corresponding to each service; when monitoring that the service flow of the OTA service occupies an available bandwidth amount larger than a preset threshold value, determining a flow control strategy based on a difference value between the service flow of the OTA service and the available bandwidth amount and the preset threshold value; and completing the service flow control of the OTA service based on the flow control strategy. Compared with the existing OTA downloading technology, the method still has the problems of flow channel blockage, high cost and potential safety hazard, the method sequences the importance of the interfaces, performs adaptive flow control on OTA downloading, utilizes asynchronous MQTT communication for the interfaces with low weight values of the importance, and uses time to replace space, thereby realizing providing more channel flow for the OTA downloading, reducing the cost and ensuring the safety and the stability of the system.

Fig. 5 is a schematic flowchart of another OTA download flow control method according to an embodiment of the present invention, and as shown in fig. 5, the method specifically includes:

and S51, scoring the importance weight value of the service interface of each service.

S52, sequencing the service interfaces of each service from large to small based on the importance weight value to obtain an importance weight value sequence.

In the embodiment of the present invention, the interaction schematic diagram of the OTA download flow control method shown in fig. 4 is combined for description, and in the embodiment of the present invention, a PageRank algorithm may be used to score an importance weight value for a service interface of each service provided by the system. And sequencing the service interfaces of each service from small to large based on the scoring result of the importance weight value to obtain an importance weight value sequence.

For example, the PageRank interface ordering of fig. 4 represents a directed graph, nodes a, B, C, and D represent web pages, directed edges between the nodes represent hyperlinks between the web pages, and weights on the edges represent the probability of random jumps between the web pages. Suppose there is one viewer who randomly walks around the web. If the viewer is at web page A, then the next step is to move to web pages B, C and D with a probability of 1/3. If the viewer is at web page B, then the next step is to transition to web pages A and D with a probability of 1/2. If the viewer is at web page C, then the next step is to transition to web page A with probability 1. If the viewer is at web page D, then the next step is to transition to web pages B and C with a probability of 1/2. If a web page has more hyperlinks pointing to the web page, the probability of randomly jumping to the web page is higher, the PageRank value of the web page is higher, and the web page is more important. The PageRank calculation can be performed on a directed graph of the Internet, and is usually an iterative process. An initial distribution is assumed, and the PageRank values of all the web pages are continuously calculated through iteration until convergence.

And S53, monitoring the flow of each service to obtain the service flow corresponding to each service.

And S54, determining the target number of the services to be subjected to communication protocol conversion based on the difference value between the available bandwidth occupied by the service flow of the OTA service and the preset threshold value.

When the OTA service flow is monitored to increase, and the service flow of the OTA service occupies the available bandwidth more than a preset threshold (for example, 90%), determining that the flow control is required. Further, the target number of the services to be subjected to communication protocol conversion is determined based on a difference value between the available bandwidth amount occupied by the service traffic of the OTA service and a preset threshold.

For example, if the service traffic of the OTA service occupies 98% of the available bandwidth, the difference between the available bandwidth occupied by the service traffic of the OTA service and the preset threshold is 8%, and it is detected that the sum of the bandwidth occupied by the 5 services is 8% or more and close to the sum, it may be determined that the target number of the services to be subjected to the communication protocol conversion is 5. Or, if it is detected that the bandwidth amount of 1 service is 10%, it may also be determined that the target number of services to be subjected to communication protocol conversion is 1, and the service may also be determined as the target service to be subjected to communication protocol conversion.

And S55, based on the target quantity, selecting a service with an importance weight value smaller than that of the OTA service from the importance weight value sequence, wherein the service with the service flow occupying available bandwidth larger than the target quantity of the service flow occupying available bandwidth of the OTA service carries out communication protocol conversion.

And S56, converting the HTTP communication protocol of the target number of services into the MQTT communication protocol.

And selecting the target services with the traffic larger than the OTA service and the importance weight value smaller than the target number of the OTA service from the importance weight value sequence to perform communication protocol conversion based on the determined target number of the services to be subjected to communication protocol conversion. The importance weighted value is smaller than that of OTA service, the representation importance is lower than that of OTA service, the transmission time can be increased through the conversion protocol, and the occupation of bandwidth is reduced. And converting the HTTP communication protocol of the target number of target services into the MQTT communication protocol. Table 1 compares the HTTP with MQTT, which uses binary transmission and smaller size.

TABLE 1

Protocol	REST/HTTP	MQTT
			Mode(s)	Request/response	Publish/subscribe
Characteristics of	Standard HTTP	Low bandwidth, low power consumption
			Transport layer	TCP	TCP
Encoding	Plain text	Binary system

And S57, detecting the service flow of the OTA service in real time.

And S58, when the service flow of the OTA service returns to the preset target, the service of the MQTT communication protocol is converted into the HTTP communication protocol again.

After the communication protocol conversion is performed on the target number of target services, the service flow of the OTA service is detected in real time, and when the service flow of the OTA service is detected to return to a preset target (for example, 40% of occupied bandwidth), the service of the MQTT communication protocol can be converted into the HTTP communication protocol again.

Fig. 6 is a schematic flowchart of a service access method provided in an embodiment of the present invention, and as shown in fig. 6, the method specifically includes:

s61, receiving a service request, wherein the service request carries target service identification information.

In the embodiment of the invention, after the communication protocol conversion of the service is carried out, the system receives the service request sent by the service calling terminal, and the service request carries the identification information of the target service to be provided with the service.

S62, determining a target service based on the target service identification information, and inquiring the current communication protocol of the target service.

And identifying the target service of the service to be provided based on the identification information of the target service, and inquiring the current communication protocol of the target service, wherein the current communication protocol of the target service may be an MQTT communication protocol.

According to the method, the importance of the interfaces is sequenced based on the PageRank algorithm, adaptive flow control is performed on OTA downloading, asynchronous MQTT communication is used for the interfaces with low weight values of the importance, space is exchanged by time, and the method can provide more channel flow for the OTA downloading, reduce the cost and ensure the safety and stability of the system.
