Embodiment bis-
As further illustrating embodiment mono-, the embodiment of the present invention provides a kind of method of load regulation, and in the time that the judgement of IW module show that current scheduling group load value is greater than the maximum of default loading range, the capacity regulating of transmission is designated as dilatation instruction, as shown in Figure 2, described method comprises:
Step 101 comprises:
Step 201, when receiving dilatation when instruction, obtain the quantity of the machine of current operation, dilatation instruction is used to indicate dilatation.
After receiving the dilatation instruction of IW module transmission, the machine quantity of current operation leaves in memory cell conventionally, can obtain the quantity of the machine of current operation by storage unit access.If do not preserve the quantity of the machine of described current operation in memory cell, send the information of system exception.
Step 102 comprises:
Step 202, determine dilatation amount according to the quantity of the machine of the first preset ratio and current operation;
Or, the first preset value is defined as to dilatation amount.
Wherein, the first preset ratio adopts a numerical value between 0%-50% conventionally.If the quantity of the machine of described current operation is 100, the first preset ratio is 20%, the quantity of the machine of described current operation 100 and the first preset ratio 20% is multiplied each other, and obtaining dilatation amount is 20.If dilatation amount exists fractional part, integer-bit adds 1, and removes fractional part, and for example: dilatation amount is 20.3, the dilatation amount obtaining is 21.
The first preset value adopts a numerical value between 0-250 platform conventionally.If described first be set to 20,, after receiving dilatation instruction, can directly the first preset value 20 be defined as to dilatation amount, now dilatation amount is 20.
In order to ensure that the machine quantity after dilatation can not exceed hardware capabilities scope, can add following steps, to ensure enough hardware supports in step 202.
Whether the quantity sum that judges the machine of described dilatation amount and described current operation is greater than ultimate load, carry out step 203 if be not more than, if be greater than, poor by the quantity of the machine of ultimate load and described current operation, be defined as dilatation amount, then carry out step 203.Thus, in the time being greater than, by redefining dilatation amount, making the quantity of the machine after dilatation operation is ultimate load, and then ensures this dilatation operation of enough hardware supports.
In addition,, if the quantity of the machine of described current operation equals described ultimate load, do not carry out dilatation.
The first preset ratio described in step 202 and described the first preset value, can be saved in memory cell, to use when next dilatation.Also can be after definite dilatation amount, to O&M, personnel send a notification message, and described notification message is for showing the dilatation amount after determining and whether needing dilatation.Whether O&M personnel are reasonable according to the determined dilatation amount of the notification message determining step 202 of receiving, reach the effect that ensures dilatation operational stability.O&M personnel confirm instruction by transmission, can control and whether carry out steps 203.
Step 103 comprises:
Step 203, in the machine of current operation determine one with reference to machine.
Obtain the information of the machine of all current operations, described information comprises device identification and Internet protocol (Internet Protocol the be called for short IP) address of equipment on network of machine.
If store with the data structure of array device identification and IP address with reference to machine, any one machine in the machine of current operation is defined as with reference to machine.Because the deploy content of the each machine in dispatch group is identical, therefore any machine can be defined as with reference to machine.
If store with the data structure of chained list device identification and IP address with reference to machine, by last unit in chained list, i.e. the machine of the last foundation in the machine of current operation is defined as with reference to machine.By storage of linked list method, can realize with the mode of operation of storehouse the foundation of machine is processed.

Step 302, obtain dilatation result according to dilatation operation mark, dilatation result is the machine quantity of operation after dilatation operation.
Can determine in the machine of current operation the machine which constructs during corresponding dilatation operates for this dilatation identifies according to described dilatation mark.
If the machine quantity of operation equals the quantity sum of the machine of dilatation amount and the front operation of dilatation operation after step 303 dilatation operation, finish dilatation operation;
If the machine quantity of operation is less than the quantity sum of the machine of dilatation amount and the front operation of dilatation operation after dilatation operation,, according to dilatation standard specimen information and the newly-increased machine of dilatation difference structure, dilatation difference is the difference of the quantity sum of the machine of operation before the rear machine quantity moving of dilatation operation and dilatation amount and dilatation operation.
Whether be less than the quantity sum of the machine of described dilatation amount and the front operation of dilatation operation by the machine quantity of operation after more described dilatation operation, can determine whether the quantity of the machine of structure conforms to dilatation amount definite in step 202.If conform to, equal, finish dilatation operation.When not conforming to, while being less than, after dilatation operation, dispatch group will keep overload, cannot ensure dispatch group service quality.Therefore, need to proceed dilatation operation, until conform to.For example: dilatation operation mark is " 1 ", it is 3 that described dilatation identifies dilatation amount in corresponding dilatation operation, dilatation result is 13, the quantity of the preoperative machine of dilatation is 12, the machine quantity 13 of the rear operation of dilatation operation is less than quantity 12 sums 15 of the machine moving before dilatation amount 3 operates with dilatation, therefore needs again to carry out dilatation operation.This time difference value is 15-13=2, if after dilatation operates again, dilatation amount is consistent with dilatation result, stops dilatation and is designated the dilatation operation of " 1 ", otherwise proceed dilatation operation.
When dilatation identifies after corresponding dilatation EO, can send report to O&M personnel, described report has been used to indicate dilatation operation.O&M personnel receive after this report, can manually check, and further ensure the success rate of dilatation operation.
In addition, because IW module judges whether dispatch group needs dilatation conventionally after certain time interval, in the process of dilatation operation, IW module still can be sent dilatation instruction, for fear of repeating dilatation operation, when when dilatation end of operation, after cooling time, again carry out the dilatation instruction of this dispatch group, within cooling time, receive in time the dilatation instruction that IW module sends, also do not carry out dilatation operation.Conventionally, cooling time is 20 minutes, and the time interval that IW module judges is 5 minutes.
