Say accompanying drawing below in conjunction with explanation, the embodiment of the invention is elaborated.
The process of the merging of a kind of pile system that Fig. 2 provides for the embodiment of the invention, this process may further comprise the steps:
S201: the member device of pile system receives the Hello announcement that other member devices send.
Member device in each pile system can regularly send the Hello announcement in embodiments of the present invention, comprises the stacking information of this Master in the Hello announcement that Master sends, and wherein comprises the identification information of Master in the stacking information of this Master.
S202: when comprising the stacking information of Master in the described Hello announcement, the stacking information of Master under the member device judgement of described pile system self in the pile system, with the stacking information of Master in the described Hello announcement not simultaneously, under self under pile system and described other member devices in the pile system election determine optimum pile system.
Wherein, the stacking information that comprises described main equipment in the Hello announcement that the main equipment of pile system sent according to the cycle that arranges in embodiments of the present invention; Or the stacking interface equipment of pile system is copied the stacking information that comprises described main equipment in the Hello announcement that the main equipment of pile system sends under self when recognizing physical link and reconnect.
In embodiments of the present invention, because can regularly sending, the Master of each pile system greets the Hello announcement, receive the member device of this Hello announcement according to the stacking information of the Master in this Hello announcement, whether the stacking information of judging the Master of pile system under local this member device of preserving is identical with the stacking information of Master during this Hello announces, the stacking information of Master in this hello announcement, with the stacking information of Master in the pile system under this member device not simultaneously, determine self under pile system carry out the merging of pile system.
Comprise when optimum pile system is determined in election in the pile system under pile system and described other member devices under self in embodiments of the present invention: the member device of described pile system preserve according to self self under the number of members information of pile system, and the stack member quantity information in the pile system under the described main equipment that comprises in the described Hello announcement, under self, elect in the pile system under pile system and described other member devices and determine optimum pile system.
S203: when pile system is non-optimum pile system under the member device self of determining described pile system, the member device of described pile system is flooded to the Hello that receives announcement under self and restarts behind each member device in the pile system, restarts after the described Hello announcement of member device inundation that wherein said Hello announcement indication receives described Hello announcement.
Member device in the non-optimum pile system is according to the hello announcement that receives, this Hello announcement is flooded to each member device in the pile system under this member device, be about to Hello and announce each member device that is flooded in the non-optimum pile system, and after this Hello announcement of this member device inundation, self restarts, and restarts after receiving this Hello announcement of member device inundation in the non-optimum pile system of this Hello announcement.Because in the process of member device inundation Hello announcement, other member devices adjacent with this member device receive this Hello announcement at first in the non-optimum pile system, therefore restart after this Hello announcement of the member device inundation adjacent with this member device, therefore can realize each member device in the non-optimum pile system take the member device that receives this Hello announcement as beginning, the process that restarts successively.
In embodiments of the present invention when member's equipment determines that pile system is optimum pile system under self, the member device in then should the optimum pile system is not done any operation, and the pile system merging process of this optimum pile system finishes.
Because the member device of pile system can periodically send the Hello announcement, can recognize this member device with other member devices that guarantee pile system and still exist in this pile system.When other member devices in the time span of setting were not received the Hello announcement of certain member device, then other member devices thought that this member device leaves this pile system.When the member device that leaves this pile system is Master, this pile system will re-elect out the new Master of this pile system.
In order to guarantee that each member device in the pile system can independently make a strategic decision to stacking merged event, each member device in the pile system can be preserved the stacking information of this pile system in embodiments of the present invention.The stacking information of this pile system comprises: the identification information of pile system, stack member quantity information, the stacking information of Master etc.Wherein the identification information of pile system can arrange for user when this member device adds pile system, and the stacking information of stack member quantity information and Master is that member device receives the Hello announcement that other member devices send and obtains.And the member device in pile system because fault etc. leaves in this pile system, the number of members information of this pile system can be upgraded, Master in this pile system leaves this pile system simultaneously, after redefining Master by election, the stacking information of the Master that each member device is preserved in the pile system also will be upgraded.
Master can send the Hello announcement according to the cycle that arranges in the pile system, and for the ease of receiving the member device of this Hello announcement, this Hello announcement according to receiving has determined whether to occur the merging of pile system in embodiments of the present invention.Master in the pile system sends the stacking information that comprises this Master in the Hello announcement in embodiments of the present invention.
Because when carrying out the merging of pile system, disconnect the member device that is connected with connection place at physical link, being disconnection or the connection that stacking interface equipment at first can recognize link, mainly is because each member device can be identified connection or the off-state of two interfaces that self link.Therefore the speed that merges in order to accelerate pile system in embodiments of the present invention, when connecting stacking interface equipment and recognize physical link and reconnect, this stacking interface equipment determines that the pile system under self carries out the merging of pile system, the interface that Master in the pile system under this stacking interface equipment imitation self reconnects by physical link sends the Hello announcement, with the merging of rapid triggering pile system.
Even the merging process of the pile system that member device identifies in the said process is wrong, but because in the Hello announcement that stacking interface equipment imitation Master sends, the stacking information that comprises this imitated Master, therefore receive the member device of other pile systems of this Hello announcement, according to the stacking information of the Master that comprises in this Hello announcement, determine whether the pile system under self carries out the merging of pile system.
When member device in the pile system receives the Hello announcement of Master transmission, stacking information according to this Master in this Hello announcement, and the stacking information of Master in the local affiliated pile system of preserving, when this pile system of stacking message identification of Master is not also selected Master in the local affiliated pile system of preserving of judgement, then the member device of pile system adds the affiliated pile system of this Master in this Hello announcement, processes according to the mode that adds newcomer's equipment in the pile system; This pile system of stacking message identification of the Master of the local affiliated pile system of preserving of judgement has been selected Master, and when the Master that identifies in the stacking information of the Master that comprises in the Master that elects and the Hello announcement is identical, think that then this Hello is advertised as the announcement that the Master of pile system regularly sends under self; This pile system of stacking message identification of the Master of the local affiliated pile system of preserving of judgement has been selected Master, and when the Master that identifies in the stacking information of the Master that comprises in this Master and the Hello announcement is not identical, then determine self under pile system carry out the merging of pile system.
The stacking information of preserving according to self for the ease of member device in embodiments of the present invention, and the Hello that Master sends announces, whether pile system carries out the merging of pile system under determining, the information of sign Master is unique in whole system in the stacking information of Master, be identification information corresponding to each Master, this identification information can be the product code information of Master, or other uniquely identified information etc.
For accelerate that member device preserves according to self its under the stacking information of Master of pile system, and the stacking information of the Master that comprises in the Hello announcement of Master transmission, whether pile system carries out the merging of pile system under determining it, can also comprise the identification information of pile system in the Hello announcement that Master sends in the invention process.
And the identification information of the pile system that the member device in the invention process in the same pile system is preserved is identical, when this pile system generation stacking splitting, even pile system division this moment is for two pile systems, but the identification information of the pile system of preserving in the member device of each pile system or identical.When the pile system after two divisions is carried out stacking merging, or two other pile systems are when carrying out stacking merging, identify for the ease of member device, the pile system identification information that two pile systems that carry out stacking merging can be set is identical, therefore carries out each member device in the pile system of stacking merging and preserves that the identification information of pile system also is identical under self.
When member's equipment receives the Hello announcement of Master transmission, the identification information of the pile system that comprises at first announcing according to this Hello, and local preserve self under the identification information of pile system, judge the identification information of the pile system that comprises in the Hello announcement, with the identification information of affiliated pile system not simultaneously, then directly abandon this Hello announcement; The identification information of the pile system that in judging the Hello announcement, comprises, when identical with the identification information of affiliated pile system, and the stacking information of the main equipment under self in the pile system, with the stacking information of main equipment in the described Hello announcement not simultaneously, then determine self under pile system carry out the merging of pile system.
When carrying out the merging of pile system in the prior art, pile system is determined optimum pile system by election, but also the possibility that little pile system becomes optimum pile system can appear at present, here the little pile system of indication is the less pile system of number of members that comprises, when this little pile system becomes optimum pile system, every the member device that comprises in the pile system of more number of members will restart, and adds pile system after the stacking merging with the identity of Slave after restarting.Because each member device that little pile system when becoming optimum pile system, comprises in the pile system of more member device will restart, and therefore the stability of pile system is exerted a certain influence.Become optimum pile system for fear of little pile system in embodiments of the present invention, improve the stability of pile system, can also comprise the stack member quantity information in the affiliated pile system of this breath Master in the Hello announcement that Master sends.And guarantee that other member devices identify this member device and still have Hello announcement in this pile system because member device can regularly send, so can preserve the stack member quantity information that pile system comprises under self in each member device.
When the pile system under member's equipment is judged self carries out the merging of pile system, the number of members information of pile system under its that preserve according to self, and the stack member quantity information in the pile system under this Master that comprises in this Hello announcement that receives, optimum pile system is determined in election.Wherein determining in election can be according to the precedence information of each member device in the optimum pile system, ruuning situation and carry out stack member quantity information that each pile system of stacking merging comprises etc. and determine.Because definite process of optimum pile system is the known technology of this area, therefore the basis that provides according to the embodiment of the invention is carried out the stack member quantity information that each pile system of stacking merging comprises and is carried out the election of optimum pile system, believe that those skilled in the art can determine corresponding method, just do not give unnecessary details at this.
Behind the Master after the definite stacking merging of member device election, the former stacking system under this Master is optimum pile system, and another pile system is non-optimum pile system.Because optimum pile system has been determined in election, processings that work of the member device in this moment optimum pile system, pile system merging process end that namely should the optimum pile system.
Receive the Hello that the Master of the optimum pile system that the member device of Hello announcement will receive sends in the non-optimum pile system and announce each other member device that is flooded in this non-optimum pile system.After this member device inundation Hello announcement, self restarts, owing to have certain linking relationship in the pile system, therefore the member device that link with this member device receives this Hello announce after, this Hello announcement of inundation, and self restart, this Hello announcement of each member device inundation in the non-optimum pile system indicated successively, and restart, until each member device in the whole non-optimum pile system restarts complete.Each member device after restarting joins in the pile system after the stacking merging with the identity of Slave equipment.
Because discovering at first the member device of pile system merging in the invention process is stacking interface equipment.Therefore when the Hello announcement of this stacking interface equipment according to reception, judge when pile system carries out the merging of pile system under self, this stacking interface equipment carries out the election of optimum pile system, but when the pile system under this stacking interface equipment self is non-optimum pile system, restart after this Hello of this stacking interface equipment inundation announcement, indication is restarted after receiving this Hello announcement of member device inundation of this Hello announcement.Therefore when pile system carries out the pile system merging under the stacking interface equipment of pile system recognizes self, trigger the process of stacking merging, thereby improved the speed of stacking merging.
The embodiment of the invention is based on Fig. 1, stacking interface equipment inundation Hello announcement to non-optimum pile system, and the process of notifying each member device to restart describes, other member device inundations Hello announcement, and notify process that each member device restarts similarly, again just do not enumerate one by one.
Pile system B is non-optimum pile system in Fig. 1, and pile system A is optimum pile system, and the stacking interface equipment among the pile system B comprises B1 and B4, and the stacking interface equipment of pile system A is A1 and A5.Because pile system B is non-optimum pile system, so B1 and B4 Hello announcement that the Master among optimum pile system-pile system A is sent is flooded to each member device among the pile system B.
Stacking interface equipment B1 is flooded to member device B2 with the path that this Hello announces by B1-B2, and after this Hello announcement of this stacking interface equipment B1 inundation, self restarts.Simultaneously because stacking interface equipment B4 and stacking interface equipment B1 are stacking interface equipment arranged side by side, therefore this stacking interface equipment B4 also can announce Hello by the path of B4-B3 simultaneously and be flooded to member device B3, after this Hello announcement of stacking interface equipment B4 inundation, self restarts.Receive member device B2 and this Hello announcement of B3 inundation of the Hello announcement of inundation, and self restarts.This moment since member device B2 and B3 restart, therefore the process of this inundation Hello announcement finishes, each member device in this non-optimum pile system has been finished the restart procedure after the stacking merging, and the member device after each restarts adds in the pile system after the stacking merging with the identity of Slave equipment.
According to Fig. 1 as can be known, carry out in embodiments of the present invention the method for distributed stacking merging by stacking interface equipment, stacking merging is processed simultaneously according to two paths, the order that namely member device restarts in pile system B is respectively " B1-B4 " and " B2-B3 ", so B2-B1 more of the prior art, the route of B2-B3-B4 has effectively shortened the time of carrying out stacking merging, and the event that the distributed stacking merging method that the embodiment of the invention provides need not to carry out stacking merging sends to Master, made a strategic decision by Master, thereby improved the efficient of stacking merging.
In the above-mentioned execution mode of the embodiment of the invention, adopt the method for distributed stacking merging to carry out the merging of pile system, task sharing to two a stacking interface equipment with Master, and stacking interface equipment is when carrying out the processing of stacking merged event, after the Hello announcement inundation that receives, restart, stacking interface equipment has carried out the Hello announcement namely to restart after the inundation even exist protocol massages this moment, therefore, the attack of attack source just is disabled, thereby reduced the attack impact of protocol massages, improved Systems balanth.
Simultaneously, because in embodiments of the present invention with task sharing to the two stacking interface equipment of Master, even this moment, Master was subject to the attack of protocol massages, communication line anxiety very, can on carrying out the impact that stacking merged event triggers by stacking interface equipment in the embodiment of the invention, therefore further not improve Systems balanth yet.
In order effectively to improve the reliability of carrying out stacking merging, Master in the pile system is according to the intrinsic cycle in embodiments of the present invention, each member device inundation Hello in pile system announces, even therefore do not receive the Hello announcement that Master sends at stacking interface equipment of first moment, namely caused losing of this Hello announcement, but because the Master in the pile system is according to the intrinsic cycle, each member device inundation Hello in pile system announces, therefore can guarantee effectively that stacking interface equipment receives the Hello announcement reliably, thereby guarantee the triggered as normal of stacking merging, and then improved the reliability of stacking merging.
The concrete merging process of the pile system that Fig. 3 provides for the embodiment of the invention, describe in conjunction with Fig. 1, and send the Hello announcement with Master according to the cycle that arranges in this execution mode, stacking interface equipment inundation Hello is advertised as example and describes, and this process may further comprise the steps:
