Detailed Description
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
Microservice is a variation of the service-oriented architectural style that calls for a single application to be divided into a set of small services that are coordinated and interworked with each other. Each service runs in its own independent process, each built around a specific business.
In order to maintain the security of network information, it is usually necessary to identify the type of file transmitted by the network device, to determine whether the transmitted file is secure, and to perform corresponding processing. However, in the conventional file type identification method, a file type identification program is usually loaded on a fixed system resource, and when a file type identification task is increased suddenly, reasonable capacity expansion cannot be performed, so that the processing is slow, and when the file type identification task is reduced, system resource waste is caused. Based on this, the embodiment of the application provides a file type identification system and method based on a micro-service architecture, which automatically adjust the number of started micro-services according to the file type identification task quantity, and reasonably utilize system resources. The method and the device can be applied to services aiming at file type identification on network equipment such as firewall equipment, switches, routers and behavior auditing, and are not limited in the embodiment of the application.
The embodiment provides a file type identification system based on a micro-service architecture. Referring to fig. 1, the file type identification system based on the microservice architecture provided by this embodiment includes an identification request module, a management module, a listening module, and a plurality of microservices. The identification request module is configured to initiate a file identification request to the management module when the file type identification is required, generate a unique file identification request ID, and start the management module to start the file type identification. The management module is configured to respond to the file identification request and generate a corresponding file identification task according to the file identification request ID, wherein the file identification task comprises file information to be identified.
Referring to fig. 3, the management module starts the listening module and self-starts at least one of the micro-services, assigning the file identification task to the micro-service. And when the management module is started, at least one micro service is loaded according to configuration defaults, so that the micro service is prevented from being dynamically loaded when the file identification tasks are few.
Referring to fig. 5, after the micro service is started, the file type identification feature library is loaded into a system memory, then a registration message is initiated to the management module, and after receiving the registration message, the management module loads the micro service into a micro service queue. The microservice queue structure provided by the embodiment of the present application is shown in fig. 2. And when file identification is needed, the management module distributes the file identification task to the micro-service in the micro-service queue.
And after the micro service finishes registration, a task processing request is initiated to the management module at regular time, and after the management module receives the task processing request, the file identification task is distributed to the micro service. After the micro service acquires the file identification task, the file type identification feature library is inquired for the file information to be identified in the file identification task, and a task processing result, namely a file suffix, is acquired. And sending the task processing result to the management module, feeding the task processing result back to the identification request module by the management module, and sending the processing result to other programs by the identification request module for subsequent processing, such as receiving or intercepting.
After the micro service acquires the file identification task, caching the file identification task in a task list of the micro service, and sequentially processing the file identification task. And each micro-service task list automatically records the number of the file identification tasks currently cached by the micro-service, namely the load capacity of the micro-service. Referring to fig. 4, the monitoring module is configured to monitor the actions of the micro service, obtain monitoring information, where the monitoring information includes the registration information, the task processing request, the task processing result, the load amount of the micro service, and the like sent by the micro service, and send the monitoring information to the management module in real time.
When the file type identification task is distributed, the management module obtains the load of all the micro services in the micro service queue, compares the load, preferentially distributes the file type identification task to the micro service with the lowest load, and reasonably distributes system resources.
The management module manages the micro-services according to the number of the file identification tasks, firstly, the management module sets a load threshold, then, the load of all the micro-services is compared with the load threshold, if the load of all the micro-services exceeds the load threshold, the number of the file identification tasks is proved to be large, at the moment, the management module dynamically starts one micro-service to share the file identification tasks, and the processing efficiency is improved. And the load threshold is set according to the size of the memory space occupied by the file identification task and the size of the memory space occupied by the file type identification feature library loaded by the micro service. For example, if one of the file identification tasks occupies a maximum memory space of 2K, and the file type identification feature library loaded by each micro service occupies about 4M of the memory, the load threshold may be set to 512 of the number of the file identification tasks cached by each micro service.
The management module sets the maximum starting number of the micro-services, when the number of the micro-services reaches the maximum starting number, the management module does not start the micro-services any more, and prevents the system resources occupied by the equipment from continuously increasing when the equipment is attacked maliciously until the equipment is exhausted. The maximum starting number is set according to the memory size of the current system, for example, the maximum starting number may be set to 8 when the memory resource is 2G, and the maximum starting number may be set to 16 when the memory resource is 4G. If a large number of file identification tasks do exist currently, the maximum starting number can be manually configured to meet the task processing requirements.
If the dynamically started micro-service does not acquire the file identification task for n times continuously, namely the micro-service is the no-load micro-service, the fact that the number of the current file identification tasks is small or the file identification tasks do not exist is proved, the management module releases the no-load micro-service, and system resource occupation is reduced.

the management module receives a file identification request initiated by the identification request module;
the management module responds to the file identification request to generate a file identification task; starting the monitoring module; starting the micro service, and distributing the file identification task to the micro service;

The management module receives the task processing result generated by the file identification task processed by the microservice;
the management module receives the load of the micro service acquired by the monitoring module; the load is the number of the file identification tasks cached by the micro-service;
the management module increases or decreases the number of the micro-services according to the load amount of the micro-services.
Referring to fig. 8, the specific steps of the management module managing the number of the micro services include: setting a load threshold; if the load amount of all the micro services in the micro service queue exceeds the load threshold value; dynamically starting a new one of the microservices; if the micro service is the idle micro service, releasing the idle micro service; the no-load micro service is the micro service which is not obtained the file identification task for n times continuously and is started dynamically.
