Machine may be adequately utilized, increases the handling capacity of system, and can be when power system capacity changes, it being capable of spontaneous, dynamic
Transmission speed is adjusted, allow whole system to reach stable state again.
The present invention primarily rests between service on the basis of request response, by sending a certain number of probe requests
To back-end services, the answer code that back-end services return is obtained, and the ratio of the shared detection packet of code dynamically adjusts according to response
Request transmission time interval, and then control client and send frequency, achieve the purpose that flow control, the program will be related to below
Flow control principle, speed regulation algorithm, flow control main points etc. are introduced.
Flow control (flow control) principle
(1) when client service initializes, starting velocity value, time packet failure threshold value, stable state is passed to and breaks through threshold value etc.
Parameter can obtain next or upper speed in velocity series to flow control system, flow control system according to initial velocity value
Value, and initial latency interval is calculated, while starting speed computational threads.
(2) when requesting server-side, flow control system can block client service according to the latency period of calculated in advance
Client request, to the waiting time after, just really send a request to server-side.At the same time, flow control system can be extracted therefrom
A certain number of request packets record time, original state code that detection packet is sent as detection packet.
(3) client gets when returning packet of server-side, the answer code of server-side can be transmitted to flow control system, flow control together
System judges whether this time packet detects packet, if it is recording its response time and status code.
(4) it after the starting of flow control system speed computational threads, can go to check that whether detection has wrapped entirely every the specified time
Packet is returned in portion, if all returning packet, calculates back packet failure rate, and whether be more than specified threshold value according to failure rate and work as
Preceding service status calculates the new velocity amplitude of current system.
Service one shares 4 kinds of states: original state, adjustment state, stable state and quickly adjusting state, every kind of state
The calculative strategy of lower velocity amplitude is all different, when original state, can search out in velocity series and thrashing rate being allowed to be more than threshold
The minimum speed value of value, and thus enter adjustment state, it eventually passes through adjustment repeatedly and obtains a stabilized speed value, into stabilization
After state, system can be according to current system failure rate with lesser step-length acceleration or deceleration, when speed is super far from stabilized speed value
When crossing certain threshold value, then enter quickly adjustment state, it in this state, can be quick according to velocity series value if failure rate is high
Slow down, so that thus failure rate is within system allowed band, and is again introduced into the adjusting stage, 3.1.3 is specific speed tune
Control algorithm.
Speed regulation algorithm is as follows:
(1) according to specified initial velocity sequence, such as: by 1,2,3,5,8,13,21,34,55,89,144,233,
377,610,987,1597,2584 ... mode sends request to the back-end, is more than threshold value until encountering load, takes overtime speed
Value and the intermediate value of a upper velocity amplitude are sent, and are continued (2).
(2) it if load is more than threshold value, takes the intermediate value of the velocity amplitude and a upper velocity series value to send, otherwise takes this
The intermediate value of intermediate value and next velocity series value is sent
(3) (2) are recycled, if system load reaches critical value in iteration section, taking current speed value is stabilized speed
Value is with the value and upper one or next velocity series value if critical value has not been reached yet in iterative boundary in system load
Section continues to start new round iteration with intermediate value, and until load reaches critical value, system reaches stable at this time, obtains current steady
Constant speed angle value then updates its value if there is last round of stabilized speed value
(4) it after system is stablized, is sent according to per second plus one velocity amplitude, whether threshold value, velocity amplitude is reached according to load
Add one or subtract one, if system is stable always, algorithm terminates, and otherwise continues (5).
(5) when transmission speed value is more than or less than the next or last velocity amplitude of stabilized speed value, or it is fast with stablizing
When the absolute value of the difference of angle value is more than a certain threshold value, system enters unstable state, if difference is positive, takes transmission speed value under
The intermediate value of one velocity series value is transmitted into adjustment state, otherwise, a velocity series value is taken to send, into quick adjustment
State until failure rate is within allowed band, and finally enters adjustment state, re-executes (2).
The implementation of the technical program can not only carry out effective monitoring to back-end services system, and can take in rear end
Business system load is effectively adjusted when too high or too low, guarantees the stability of back-end services, and adequately utilize as far as possible
Back-end server resource improves the utilization rate of machine resources.
