Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
The main thought of the distribution method of device number of stacked system of the present invention is: make the information such as priority that device number can marking equipment; And can artificially control, make controllability stronger; Reserved number section function well is applicable to the expansion of pile system fully; Keep the information stability that still can keep pile system when the number segment function makes the stacked system equipment upheaval.Thereby make the distribution reasonability and the reliability of device number stronger, strengthened the controllability and the stability of pile system.
The distribution method of device number of stacked system of the present invention comprises:
When upheaval appears in the pile system member device, use the device number reservation scheme to guarantee the stability of the information of piling up; Concrete steps are: main equipment and be equipped with equipment and preserve the device number of member device and the corresponding relation of MAC (medium access control) address; When member's equipment left pile system for some reason, the main equipment of this pile system kept the device number of distributing to this member device; When this member device added this pile system again, described main equipment was assigned as the device number of its reservation to this member device according to the MAC Address of this member device and the corresponding relation of being preserved.When main equipment leaves pile system, be equipped with equipment and keep its device number; When described main equipment adds fashionablely again, though not necessarily also become main equipment, but still for it distributes the device number kept, promptly the device number of described main equipment was with originally the same.
As from the foregoing, when the pile system member need leave and add pile system--such as situations such as device upgrades, when presenting oscillatory regime, its device number that is assigned with temporarily keeps, during this member device leaves pile system, if have new equipment to add pile system, can not use the device number that leaves the member; Based on this mechanism, when the member device that leaves returns to pile system, still can use the stack equipment that before had been assigned with number.
Certainly, if the number that can be assigned with is insufficient, all be used because of the expansion of system and finish, then when not having device number to distribute to initiate member device, main equipment will leave system time the device number of long member device distribute to this initiate member device; The specific implementation method can be following in several any:
(1) main equipment is by the device number of the journal member device that leaves pile system, when member's equipment adds fashionable its device number of deletion in the equipment records that leaving again; When not having device number to distribute to initiate member device, distribute to newcomer's equipment with leaving the device number that leaves the member device of system in the equipment records at first.
(2) when member's equipment left this pile system, main equipment picked up counting, and fashionablely stops timing and timing is reverted to 0 when member's equipment adds again; When not having device number to distribute to initiate member device, the device number of the member device that time departure is the longest is distributed to newcomer's equipment.
(3) time threshold and being kept in the main equipment is set; When member's equipment left this pile system, main equipment picked up counting from 0, fashionablely stops timing and timing is reverted to 0 when member's equipment adds again; When the timing of a member device correspondence surpasses described threshold value,, its device number is left out from the alternative formation if this member device adds again with number adding optional equipment formation of its corresponding equipment; When not having device number to distribute to initiate member device, from optional equipment number, select one and distribute.This time threshold can artificially be selected according to actual conditions, may leave the maximum duration of pile system when being in oscillatory regime greater than equipment.
Be not limited to above implementation in the practical application, only do reference here.
Certainly, the number that can be assigned with when needing only systems organization is enough, stack equipment number multiplexing situation just can not occur.
The stable information stability that has guaranteed pile system thus of device number, the management of pile system is also more simple.
The distribution method of device number of stacked system of the present invention can also comprise: main equipment comes distributing equipment number according to the priority of each equipment in the pile system and/or MAC Address; Can but be not limited to the more little device number of the high more devices allocation of priority.
The stacked system equipment Determination of priority can be finished automatically by system, also can carry out artificial appointment, thereby can influence the generation of main equipment by influencing priority facility.
Concrete steps are: the priority facility of pile system can be finished setting automatically by system, and promptly under default situations, all devices priority is consistent.But the equipment importance of pile system generally all is distinguishing, thus its priority preferably also have any different, thereby can have influence on the election of main equipment and the distribution of device number.Such as important to some position, perhaps stable extraordinary equipment can artificially dispose its priority, makes its priority be better than other equipment, and this equipment can be elected to main equipment like this, is convenient to the management of pile system.
The distribution method of device number of stacked system of the present invention can also comprise: the main equipment of pile system divides timing carrying out device number, checks numbers and reserves; Be after per minute is joined some numbers, just reserve some numbers and do not distribute that it is fashionable to have treated that newcomer's equipment adds, give newcomer's equipment the number assignment of reserving.
The scheme of above-mentioned reserved number and above-mentioned scheme according to priority and/or MAC Address assignment numbers both can be used separately, also can combine use; Combine to use and be exactly: the device number that will be used to distribute is divided into some number segments, and each number segment is corresponding to different priority or MAC Address or its combination; Be the device number in each stack equipment distribution number segment corresponding with it; And in each number segment, reserve some device numbers and do not distribute; Thereby the device number of stacked system after guaranteeing to expand in the future represents that information is not upset; For distributing the device number in the number segment corresponding with it, each stack equipment is meant: give the equipment that possesses corresponding priority order of the device number in the number segment or Random assignment.
When according to the priority assignment device number, concrete steps comprise:
Precedence information according to all stack equipments, can stipulate to distribute to priority the device number of high equipment be positioned at certain optimum number segment, such as main equipment oneself is exactly the highest equipment of priority, so the device number of himself is 1, the same high equipment of other priority is distributed in 2 to 10 of optimum number segments successively.
For the equipment of suboptimum, be similar to the highest equipment of priority again, the reservation that can carry out the suboptimum number segment distributes, between 11 to 20; Same for the general equipment of priority, distribution method is similar equally, can be set to after 21.
The situation of joining device number according to the MAC Address five equilibrium is similar, repeats no more.
Certainly, the number segment is here formulated and can be adjusted according to the pile system situation of reality, such as in the bigger pile system of scale, the optimal device number segment can be set 1 to 30; The meaning is to have reserved 30 device numbers to the highest equipment of priority; The equipment number section of priority suboptimum is between 31 to 70, and the meaning is to have reserved 40 device numbers to give equipment of priority suboptimum or the like;
Adopt this mode, the device number of pile system can reflect the situations such as priority facility of pile system, and making device number is not only device number, but has other meaning such as priority; These device number reservation means can be reserved device number fully, even after the pile system expansion, stack equipment information is not still upset, make the device number that piles up have stable and long-range meaning.
After being used in combination with the device number reservation scheme of preamble, not only can make stack equipment number can fully react the situations such as priority facility of pile system, fully tackle the pile system expansion; And still can keep the stable of pile system information can make stack equipment upheaval occur the time.
Further be illustrated with an application example of the present invention below.
In the step of device number allocated phase as shown in Figure 4, comprising:
The stack equipment distributing equipment that the main equipment of step 402, pile system takes second place for priority again number, the equipment reserved number section that priority is taken second place is set to 11 to 20; Allocation result is shown in Fig. 5 (b).
If the initial device number of step 405 is assigned to 21 equipment because vibration appears in device upgrade or other reasons, when then adding pile system again, still use the device number 21 that keeps at every turn, allocation result is shown in Fig. 5 (e).
Adopt the device number distribution method of stacking route switching device as herein described system, the information such as priority that stack equipment number can marking equipment; Can artificially control, make controllability stronger; The method of reserving device number can well be applicable to the expansion of pile system; The function of retaining device number still can keep the information stability of pile system when making the equipment vibration.Thereby the reliability and stability of pile system are strengthened greatly, and simplify the management of pile system, improve the controllability of pile system.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
