Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 1 is the flow chart of the suppressing method of port oscillation according to the embodiment of the present invention.As shown in Figure 1, following process is comprised according to the suppressing method of the port oscillation of the embodiment of the present invention:
Step S102: the current concussion situation of timing acquisition port, and be mapped as penalty value;
Wherein, above-mentioned penalty value is the value calculated by algorithm according to the frequency of up, down event, require that algorithm increases according to certain rules according to the frequency of up, down event, along with the time decays according to certain rules, such as: penalty value along with the linear increase of up, down event, along with the time is with exponential damping.
Step S104: judge whether penalty value is greater than suppression threshold value;
Wherein, above-mentioned suppression threshold value is the value pre-set, and when penalty value is greater than this value, up, down time occurred here is no longer valid, and is marked as disarmed state, and not reporting port virtual condition change, reporting port state is down.
Step S106: if then arranging port is failure state, and be failure state to the state of upper-layer protocol module reporting port.
In correlation technique, because port frequently shakes, upper-layer protocol is caused repeatedly to shake, also impact is caused to the CPU of equipment, equipment and network are produced and comparatively has a strong impact on, adopt said method, effectively can suppress the concussion frequency of port, and reduce the impact of port oscillation on communication equipment and whole network stabilization.
In preferred implementation process, in order to map above-mentioned penalty value, need timing statistics ports physical state variation frequency (i.e. port oscillation frequency), particularly, timer timing read port concussion frequency can be adopted, also can adopt this concussion frequency of other mode timing acquisitions.
Owing to being just add up above-mentioned concussion frequency every a time period (regularly), thus the time period can be continuous print multiple time period.For initial (first) time period, in step S602, penalty value can be mapped in the following manner: make penalty value become to increase progressively relation with the frequency of oscillation f of port within this time period (first time period).
Such as, within first time period, can be described by following formula and map penalty value:
Penalty value=initial value+exp (f) * ln2
Known by above formula, penalty value and frequency of oscillation f exponentially increase progressively relation.
Such as, within first time period, can also be described by following formula and map penalty value:
Penalty value=initial value+this period frequency of linear coefficient *
Known by above formula, penalty value and frequency of oscillation f is linear increases progressively relation.
In the other times section except first time period (time period namely after first time period), in step S602, penalty value can be mapped in the following manner: penalty value and the port concussion frequency f within this time period becomes to increase progressively relation, and become to successively decrease relation with the time interval T between this time period and first time period.
Such as, in the other times section except first time period, can be described by following formula and map penalty value:
Penalty value=last time period penalty value * attenuation coefficient+exp (this period frequency) * ln2
Wherein, 0 < attenuation coefficient < 1, known by above formula, penalty value and frequency of oscillation f exponentially increase progressively relation, and (embodied by attenuation coefficient with the relation that becomes to successively decrease of the time interval T between this time period and first time period, because along with the time increases, once, the corresponding reduction of penalty value once for every iteration).
Such as, in the other times section except first time period, can also be described by following formula and map penalty value:
Penalty value=last time period penalty value * attenuation coefficient+this period frequency of linear coefficient *
Wherein, 0 < attenuation coefficient < 1, known by above formula, penalty value and frequency of oscillation f is linear increases progressively relation, and (embodied by attenuation coefficient with the relation that becomes to successively decrease of the time interval T between this time period and first time period, because along with the time increases, once, the corresponding reduction of penalty value once for every iteration).
Preferably, if penalty value is less than reuse threshold value (wherein, reuse threshold value and be less than or equal to suppression threshold value), said method can also comprise following process:
(1) judge whether port is in disarmed state;
(2) if then remove the disarmed state of port, and the actual concussion state of reporting port (port actual physics variable condition).
Wherein, reusing threshold value is the value pre-set, and when penalty value is by being greater than after suppression threshold value decays to and be less than and reuse threshold value, this port just comes into force again, reporting port state variation.
In preferred implementation process, recovering the change of reporting port actual physics has two kinds of methods: automatically recover and manually recover.Automatic recovery method is as follows: timing read port change frequency, calculates penalty value according to algorithm always, until penalty value be less than setting reuse threshold value time, recover normal port status and report, up, down state of this port is just effectively.Manual restoration methods is as follows: cancel port holddown by command set, and remove the penalty value calculated, recover normal port status and report, up, down state of this port is effective.
Preferably, if penalty value is greater than maximum penalty value (wherein, maximum penalty value is greater than suppression threshold value), said method can also comprise following process: penalty value is set to maximum penalty value.
Wherein, maximum penalty value is the value pre-set, if according to punishing that the penalty value that algorithm calculates exceedes this value, is then set to this value (being used for controlling the longest suppression time).

Step S204: according to physical state change frequency and the Time Calculation penalty value of specific algorithm port;
Step S206: the penalty value calculated in real time and suppression threshold and maximum penalty value are compared;
Step S208: if penalty value is greater than suppression threshold be less than maximum penalty value, port is set to holddown, and be down to upper strata uploaded state;
Step S210: if penalty value is greater than maximum penalty value, then penalty value is set to the numerical value of maximum penalty value, port is set to holddown, and be down to upper strata uploaded state;
Step S212: if penalty value is less than suppression threshold value, judges whether port was in holddown last time;
Step S214: if be in holddown, removes the holddown of port, to the state of upper strata reporting port reality.
