Technical Field
The invention relates to the technical field of computer communication, in particular to a server, a current-limiting protection system based on a delay queue and a method.
Background
Currently, for high concurrent requests, a server usually sets a First-in-First-out (FIFO) queue for overload protection.
Semaphore control may be performed to limit the amount of concurrent request processing, where requests that get a token are allowed to the server to be processed, and requests that do not get a token are treated as overloaded and return busy information. Furthermore, the current limiting protection can be further carried out by controlling the passing request quantity in a fixed time interval through a counter and time.
However, the conventional queue protection strategy can only address the situation that the processing capacity of the server is insufficient, and cannot satisfy the situation that the processing capacity of the server is excessive and is limited by network card flow resources, for example, and when the flow limit protection is performed by controlling the passing request amount in a fixed time interval through a counter and time, the time interval is fixed, and the situation that the user requests are randomly distributed cannot be satisfied.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
First embodiment
Fig. 1 is a schematic structural diagram of a server according to a first embodiment of the present invention. As shown in fig. 1, the server 10 includes an acquisition module 100 and a flow control module 101.
The obtaining module 100 is configured to collect and analyze performance parameters of the server 10, so as to obtain a threshold of the number of requests in the delay queue and an occupation time of the requests.
Specifically, the performance parameters of the server 10 may include, but are not limited to, performance parameters corresponding to network card traffic and use cases of the input and output interfaces, respectively. Of course, those skilled in the art will understand that the performance parameters of the server 10 may also include, but are not limited to, the corresponding performance parameters of the central processor load condition, etc.
The traffic control module 101 is configured to receive a request sent by a user terminal, add the request to a delay queue when the number of requests in the delay queue does not exceed a threshold, and leave the request from the delay queue when the request in the delay queue meets the occupancy time.
Specifically, the user terminal may be, but is not limited to, a mobile phone, a tablet computer, and the like. The user terminal may communicate with various networks, such as the internet, an intranet, a wireless network, for example, sending a request to a server over the wireless network. The wireless network may comprise a cellular telephone network, a wireless local area network, or a metropolitan area network. The wireless networks described above may use various communication standards, protocols, and technologies.
The delay queue may be, but is not limited to, a delay queue with a priority of a timestamp, and it is understood by those skilled in the art that the delay queue may also be a queue with a priority of other types, such as a type of request.
Fig. 2 shows a schematic structure of a delay queue. The delay queue is a delay queue with a timestamp as a priority, that is, the head of the delay queue is a request with a smallest timestamp (the time of enqueuing at this moment), and the tail of the delay queue is a request with a largest timestamp. As shown in fig. 2, the delay queue includes 9 requests, and the time in the delay queue represents the remaining time for dequeuing the corresponding request, for example, if the threshold of the number of requests in the delay queue is 9 and the occupancy time of the request is 1 second(s), then only after 100 milliseconds (ms), it is possible to have the next request to join the delay queue, that is, when the delay queue is full (the number of requests reaches the threshold), the next request can join the delay queue only when there is a request to leave the delay queue. Furthermore, each request must satisfy 1s in the delay queue to leave the delay queue.
It is worth mentioning that each request must meet the floor time in the delay queue to leave the delay queue, but the time when the server actually responds to the request may be, but is not limited to, the time when the request leaves the delay queue before.
The server provided by the embodiment of the invention can respond to the requests of the user terminal in real time according to the number of the requests in the delay queue, can meet the condition of random distribution of the user requests, correspondingly reduces the number of the requests in the delay queue when the requests in the delay queue meet the occupation time, and can meet the condition of excess processing capacity of the server.
