The method comprises the steps of: selecting a flow balance policy in which the flow difference among member ports in a unit time is minimum as the flow balance policy used by the aggregation port; in the unit time, periodically judging whether the flow difference among the member ports is increased and the change amplitude exceeds a set range or not when the aggregation port uses the selected flow balance policy; if the flow difference among the member ports is increased and the change amplitude exceeds the set range, re-determining the flow balance policy in which the flow difference among the member ports in the unit time is the minimum as the flow balance policy currently used by the aggregation port; or else, remaining the current flow balance policy of the aggregation port unchanged. Through the invention, the configuration of the optimal flow balance policy can be automatically realized; when the flow difference among the member ports changes, the flow balance policy is adjusted in real time to obtain the optimal flow balance policy after the flow changes and ensure that the flow balance policy can play a real role in the flow balance along with the flow change of the aggregation port.
Description
Technical field
The present invention relates to network communication field, relate in particular to a kind of method, device, aggregation port and network equipment of aggregation port flow equilibrium.
Background technology
Port trunking is meant a plurality of trunkings is formed a virtual port that converges together, to realize out/to go into load sharing in each member port in converging port, higher connection reliability also is provided simultaneously.The formed port that converges is commonly referred to aggregation port (Aggregate Port), and the member who forms aggregation port is called the polymerization member port.
The great advantage that port trunking in contrast to common port is the bandwidth that can provide bigger, and is as shown in Figure 1, have on the device A 8 100,000,000 mouthfuls with equipment B on 8 100,000,000 mouthfuls be connected, each is connected can only provide one 100,000,000 bandwidth in logic.If 8 mouths of device A are formed an aggregation port; 8 mouths are also formed an aggregation port on the equipment B; Just being equivalent to two equipment connects through an aggregation port; Can logically simulate the bandwidth that approaches a gigabit mouth like this, just exist 8 Member Links to bear the flow of this aggregation port jointly.
Flow equilibrium configuration on the aggregation port is meant that aggregation port can be assigned to flow in its Member Link according to the feature field of message fifty-fifty, concentrates on indivedual member ports to avoid flow.
At present several kinds of strategies commonly used of the flow equilibrium of aggregation port comprise: based on source MAC, based on target MAC (Media Access Control) address, based on source MAC+target MAC (Media Access Control) address, based on source IP address, based on purpose IP address and based on the strategy of source IP address+aggregation port flow equilibriums such as purpose IP address.
With the flow equilibrium strategy based on source MAC is example, and its specific practice is that the source MAC according to message is assigned to message in each member port of aggregation port and transmits.The message of homology MAC not, the member port of forwarding is different, and the message of identical sources MAC is transmitted from same member port.Through the flow equilibrium strategy, can the flow on the AP mouth be assigned on each member port by certain rule fifty-fifty, avoid transmitting from certain member port in all flow sets, improve the service efficiency of aggregation port.
The flow equilibrium strategy of aggregation port commonly used can only be selected a configuration in advance by the keeper at present, in case network traffics change, the flow equilibrium strategy on the aggregation port possibly no longer be optimum, therefore can't play the effect of preferable balanced flow.
For instance, application scenarios as shown in Figure 2, device A is connected through an aggregation port with equipment B, and device A has also connected equipment X and equipment Y simultaneously.Aggregation port between device A and the equipment B comprises two member ports.Suppose that the keeper is based on the flow equilibrium strategy of source MAC to the flow equilibrium strategy of aggregation port configuration between device A and the equipment B; When equipment X and Y needs and outer net communication; The MAC Address of supposing equipment X is 00-00-00-00-00-01, and the MAC Address of equipment Y is 00-00-00-00-00-02, according to the flow equilibrium strategy of configuration; The flow of equipment X is from link 1 transmission, and the flow of equipment Y is from link 2 transmission.In case equipment Y breaks down, when only remaining equipment X and outer net communication, still from link 1 transmission, this has just caused the waste of link 2 to all flows.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of method, device, aggregation port and the network equipment of a kind of aggregation port flow equilibrium that the embodiment of the invention is provided is at length explained.
The method of the aggregation port flow equilibrium that the embodiment of the invention provides, as shown in Figure 3, comprising:
The flow equilibrium strategy of each member port flow difference minimum is as the employed flow equilibrium strategy of aggregation port in S301, selection unit's time;
S302, periodically in the unit interval, judge this aggregation port under the situation of using selected flow equilibrium strategy, whether each member port flow difference becomes big and amplitude of variation exceeds the scope of setting; If carry out following step S303; If not, carry out following step S304;
S303, confirm the minimum flow equilibrium strategy of each member port flow difference in the unit interval again, and the said flow equilibrium strategy that will confirm again turns to execution in step S302 then as the presently used flow equilibrium strategy of said aggregation port;
S304, to keep said aggregation port present flow rate equilibrium strategy constant, turns to execution in step S302 then.
At length explain in the face of above-mentioned each step down.
In above-mentioned steps S301～S304; Aggregation port start working initial; Do not adopt the method for the pre-configured flow equilibrium strategy of keeper; But the size of each member port flow difference of this aggregation port elects the minimum flow equilibrium strategy of a difference as the employed flow equilibrium strategy of current aggregation port under the various flow equilibrium strategies of supporting according to this aggregation port; Follow-up or else being completely cured according to the situation of change of each member port flow difference of this aggregation port that obtains in each cycle carried out suitable adjustment.
Specifically; The step of the flow equilibrium strategy of each member port flow difference minimum in selection unit's time among the above-mentioned steps S301; And among the step S303, confirm the minimum flow equilibrium strategy of each member port flow difference in the unit interval again, realize through following manner:
To each flow equilibrium strategy that this aggregation port is supported, this aggregation port uses under the situation of this flow equilibrium strategy in the unit of account time, the deviation ratio of speed in the unit interval;
Every kind of resulting deviation ratio of flow equilibrium strategy is compared, select the minimum flow equilibrium strategy of deviation ratio as the minimum flow equilibrium strategy of each member port flow difference in the unit interval.
In above-mentioned steps S302, aggregation port is under the situation of using selected flow equilibrium strategy, and each member port flow difference in the unit interval also realizes through the deviation ratio that calculates this aggregation port speed in this cycle.
Specifically; Among above-mentioned steps S301～S303; The deviation ratio of aggregation port speed has reflected the size of flow difference between each member port of this aggregation port, proves that more greatly then flow differs greatly between each member port of this aggregation port, has the unbalanced phenomenon of flow each other; More for a short time, prove that then flow difference is less between each member port of aggregation port, flow is comparatively balanced each other.Its computational methods are following:
1, in the unit interval, calculate the standard deviation of the speed of this each member port of aggregation port, and the summation of each member port speed;
2,, obtain the deviation ratio of speed in this aggregation port unit interval with the summation of standard deviation divided by each member port speed.
For instance, supposing has N member port in this aggregation port, and in the unit interval, the speed of each member port is respectively X
1, X
2... X
n, the formula of the standard deviation of the speed of this each member port of aggregation port is following in the unit of account time:
W is X
1, X
2... X
nMean value;
X
1, X
2... X
nBe the speed of N member port in the unit interval.
Wherein:
Why adopt the standard deviation of each member port speed to weigh the size of each member port flow difference; Be because standard deviation is used for the discrete degree of characterization data; In the formula of aforementioned calculation rate variance; The standard deviation of each member port speed is to eliminate the influence that the interface rate absolute value is brought divided by the purpose of aggregation port speed (each member port speed summation); Make the aggregation port of different bandwidth to weigh the scope whether the deviation ratio variation surpasses setting through a unified threshold value; For aggregation port can be distributed to different flow on each member port more equably, need choose the minimum flow equilibrium strategy of the deviation ratio of speed of each member port as the presently used flow equilibrium strategy of aggregation port.
Preferably, the method for the aggregation port flow equilibrium that the embodiment of the invention provides after above-mentioned steps S301, also comprises the step of preserving selected flow equilibrium strategy deviation ratio of speed in the unit interval.
Thus; In above-mentioned steps S302; Big and the amplitude of variation of each member port difference in flow mutation exceeds the scope of setting in this unit interval; Can judge through following manner: at first calculate the deviation ratio of this aggregation port speed in this unit interval, whether the deviation ratio of judging aggregation port speed in this unit interval is greater than the deviation ratio of preserving before; In judged result is under the situation that is, whether the difference between the deviation ratio of further judging aggregation port speed in this unit interval and the deviation ratio of preservation is greater than the first threshold of setting; If, then can judge should the unit interval in the big and amplitude of variation of each member port difference in flow mutation exceeded setting range.
Preferably; At the flow equilibrium strategy of above-mentioned steps S303 each member port flow difference minimum in definite again unit interval and after with its step as the presently used flow equilibrium strategy of said aggregation port; The method of the aggregation port flow equilibrium that the embodiment of the invention provides, can also carry out following step:
The step S303 deviation ratio of definite flow equilibrium strategy speed in the unit interval again and the deviation ratio of preservation are compared; If the deviation ratio that the deviation ratio of flow equilibrium strategy speed in the unit interval of confirming is again preserved is little, use the deviation ratio of flow equilibrium strategy speed in the unit interval of confirming again to upgrade the deviation ratio of being preserved so.
If flow equilibrium strategy deviation ratio of speed in the unit interval of confirming again is not less than the deviation ratio of being preserved, do not carry out the operation that the deviation ratio of preserving is upgraded so.
The benefit of doing like this is; If the deviation ratio that the deviation ratio of flow equilibrium strategy speed in the unit interval of confirming is again preserved is little, explain that then current network flow changes towards the direction that more meets the present flow rate equilibrium strategy, uses the flow of each member port of this port under this flow equilibrium strategy more to be tending towards even in other words; If upgrade the deviation ratio of preserving this moment; Make that adjustment next time is to be the adjustment of carrying out after the basis is judged based on the deviation ratio after the current renewal, so because the deviation ratio of preserving is before littler, for the adjustment next time of flow equilibrium strategy; Its trigger condition then seems more strict and (can imagine; If there is the trend that constantly diminishes in the deviation ratio of preserving, extreme perfect condition is that the deviation ratio of being preserved is zero, just need adjust accordingly as long as the unbalanced state of each port flow promptly occurs); Under the constant situation of first threshold; The deviation ratio that triggers the flow equilibrium strategy reduces, and has improved the sensitivity of adjustment, makes that the adjustment of flow equilibrium strategy is more flexible.
Preferably; For fear of the related operation of the network continuous initiation flow equilibrium strategy that the Traffic Anomaly shake causes in the short time and the concussion of adjustment; In the method for the above-mentioned aggregation port flow equilibrium that the embodiment of the invention provides; Can also be in S302, when judging in this unit interval the big and amplitude of variation of each member port difference in flow mutation at every turn and exceeding the scope of setting, the number of times of situation that the big and amplitude of variation of each member port difference in flow mutation in the unit interval exceeds the scope of setting appears in statistics; And whether the number of times of judging current period statistics reaches second threshold value of setting, and when reaching said second threshold value, just turns to execution to confirm the step of the flow equilibrium strategy of member port flow difference minimum in the unit interval again.Through setting the number of times that specific appearance difference in flow mutationization exceeds setting range; When this situation of appearance reaches preset threshold; Just initiate to confirm again the step of the flow equilibrium strategy that flow difference is minimum, can avoid the concussion problem that the Traffic Anomaly shake is caused in the short time.
In order to be illustrated more clearly in the method for the above-mentioned aggregation port flow equilibrium that the embodiment of the invention provides, simple instance of following mask describes:
As shown in Figure 4, device A is connected through an aggregation port with equipment B, and this aggregation port is made up of 2 member ports.3 equipment X, Y, Z and A are connected, and 2 equipment M, N and equipment B are connected.Suppose that device A only supports based on source MAC, based on these two kinds of flow equilibrium strategies of purpose MAC.The source MAC that supposes equipment X, Y, Z is respectively 00-00-00-00-00-01,00-00-00-00-00-02 and 00-00-00-00-00-03.The source MAC that supposes equipment M, N is respectively 01-23-45-00-00-01 and 01-23-45-00-00-02.Unit interval preset on the device A is 1 minute, and first threshold is 0.2.
The selection of aggregation port flow equilibrium strategy and adjustment process are explained as follows:
Suppose when initial, equipment X, Y, Z per minute respectively send 100 messages to equipment M, N respectively, and the flow of per minute aggregation port is 600 messages so.
1, in order to select the minimum flow equilibrium strategy of each member port flow difference; Aggregation port on the device A at first selects first equilibrium strategy to be the flow equilibrium strategy based on source MAC; Aggregation port uses this strategy that the message of X equipment and the transmission of Z equipment is sent from link 1, and the message that Y equipment is sent sends from link 2.When expiring in first minute, adding up the last transmission of one of them member port port1 message number is 400, and another member port port2 goes up and sends the message number is 200.The standard deviation that calculates speed under this flow equilibrium strategy is 100, and deviation ratio S is 0.16.
2, in second minute, it is the flow equilibrium strategy based on purpose MAC that the aggregation port on the device A is selected second flow equilibrium strategy, and this strategy is that the message of M sends from link 1 with destination device, is that the message of N sends from link 2 with destination device.When expiring in second minute, statistics member port port1 goes up and sends the message number is 300, and another member port port2 goes up and sends the message number is 300.Calculate that the speed standard difference is 0 under this flow equilibrium strategy, deviation ratio S is 0.
3, compare through the deviation ratio that two unit interval are obtained respectively, aggregation port is chosen based on the flow equilibrium strategy of purpose MAC and is used on the device A, and preserves current deviation rate S=0.
After; Every at a distance from one minute, calculate a deviation ratio S` on the device A, if calculate deviation ratio S` diminish or become greatly but amplitude of variation less than 0.2; Then do not revise the flow equilibrium strategy of using on the aggregation port, otherwise then need carry out the election of flow equilibrium strategy again.
4, suppose in the running that equipment N breaks down and closes, then network traffics become X, Y, and the Z per minute sends 100 messages towards equipment M.
This moment, device A was when the computation rate standard deviation, because all message purpose MAC are M, so only transmission on link 1.Statistics member port port1 goes up and sends the message number is 300, and another member port port2 goes up and sends the message number is 0.Calculate under this flow equilibrium strategy based on purpose MAC, the standard deviation of each member port speed is 150, and deviation ratio is S`=0.5.Contrast S` becomes big than S and amplitude of variation surpasses 0.2, and need re-elect the flow equilibrium strategy this moment.
The selected flow equilibrium strategy of aggregation port on the device A is based on source MAC, and when expiring in one minute, statistics port1 goes up and sends the message number is 200, and the last transmission of port2 message number is 100.Calculate that the speed variance is 50 under this flow equilibrium strategy, deviation ratio S is 0.16.
2 kinds of flow equilibrium strategies being supported of contrast, less based on the flow equilibrium strategy deviation ratio of source MAC, be flow equilibrium strategy with the flow equilibrium strategy modification of aggregation port based on source MAC.
