Abstract
The invention provides a delay-queue-based current-limiting protection method. The method comprises: performance parameters of a server are collected and analyzed and a request number threshold value in a queue and request occupied time are obtained; whether the request number in the queue exceeds a threshold value is determined; if not, the request is added into the delay queue, and the request leaves from the delay queue when the request meets the occupied time; and if so, busy information is sent to a user terminal. In addition, the invention also provides a server and a delay-queue-based current-limiting protection system. Therefore, requirements on conditions of user request random distribution and server processing capacity excess can be met.
Description
Technical field
The present invention relates to computer communication technology field, more particularly to a kind of server, based on time delay team
The current-limiting protection system and method for row.
Background technology
At present, asked for high concurrent, server would generally set to carry out overload protection and first enter elder generation
Go out (First Input First Output, FIFO) queue.
In order to the treatment quantity of limiting concurrent request can carry out semaphore control, wherein, take letter thing
The request of feelings token then allows server to enter treatment, and the request for not taking letter thing token is then considered as
Overload and return to busy information.Additionally, further, can also be solid by counter and time control
The request amount passed through in interval of fixing time carries out current-limiting protection.
But existing queue Preservation tactics can only be directed to the not enough situation of server handling ability, it is impossible to full
Sufficient server handling ability is superfluous and be limited to the situation of such as network interface card floating resources etc., and pass through to count
When the request amount that passes through carries out current-limiting protection in device and time control set time interval, due to time zone
Between be fixed, it is impossible to meet the situation of user's request random distribution.
The content of the invention
In view of this, the present invention provides a kind of situation and server that can meet user's request random distribution
The current limiting protecting method based on time delay queue of the superfluous situation of disposal ability.
The embodiment of the present invention provides a kind of current limiting protecting method based on time delay queue, described based on time delay
The current limiting protecting method of queue includes collecting the performance parameter of simultaneously Analysis server, so as to obtain time delay team
The threshold values of the number of requests in row and the occupy-place time of request；Receive the request that user terminal sends；Sentence
Whether the number of requests in the disconnected time delay queue exceedes threshold values；If the number of request in the time delay queue
The request is then added the time delay queue, and meet described in the request by amount not less than threshold values
During the occupy-place time, the request is allowed to leave the time delay queue；And if the request of the time delay queue
Quantity exceedes threshold values, then send busy information to the user terminal.
The embodiment of the present invention also provides a kind of server, and the server includes acquisition module, flow control
Molding block.The acquisition module is used to collect and analyze the performance parameter of the server, so as to obtain
The threshold values of the number of requests in time delay queue and the occupy-place time of request；The flow-control module is used for
When receiving the request that user terminal sends, and number of requests in the time delay queue not less than threshold values,
The request is added into the time delay queue, and the request in the time delay queue meets described
During the occupy-place time, the request is allowed to leave the time delay queue.
The embodiment of the present invention also provides a kind of current-limiting protection system based on time delay queue, described based on prolonging
When queue current-limiting protection system include user terminal and server；The user terminal is used to send asks
Ask to the server；The server is used to collect and analyze the performance parameter of the server, from
And threshold values and the occupy-place time of the request of number of requests in time delay queue are obtained, and prolong described
When queue in number of requests not less than threshold values when, the request is added into the time delay queue, and
When the request in the time delay queue meets the occupy-place time, the request is allowed to leave described prolonging
When queue.
Server of the invention, the current-limiting protection system and method based on time delay queue basis can prolong in real time
When queue in request quantity response user terminal request, user's request random distribution can be met
Situation, and the request in time delay queue when meeting the occupy-place time just by time delay queue
Number of requests is correspondingly reduced, and can meet the superfluous situation of server handling ability.
It is that above and other objects, features and advantages of the invention can be become apparent, it is cited below particularly
Preferred embodiment, and coordinate institute's accompanying drawings, it is described in detail below.

The server is used to collect and analyze the performance parameter of the server, so as to obtain time delay team
The threshold values of the number of requests in row and the occupy-place time of the request, and asking in the time delay queue
When seeking quantity not less than threshold values, the request is added into the time delay queue, and in the time delay queue
In request when meeting the occupy-place time, allow the request to leave the time delay queue.
10. the current-limiting protection system of time delay queue is based on as claimed in claim 9, it is characterised in that
Service condition institute of the performance parameter of the server including network interface card flow, input/output interface is right respectively
The performance parameter answered.
The 11. current-limiting protection systems based on time delay queue as claimed in claim 9, it is characterised in that
The time delay queue is the time delay queue with timestamp as priority.
