Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.
The invention provides the method and system that a kind of veneer realizes that mainboard is switched; to finish the demand of Board Protection Switching; its main feature is: reversed process does not need to control the hardware intervention of veneer etc.; and realize masterslave switchover by the veneer auto-negotiation fully; it approaches a kind of pure software mode, and the veneer auto-negotiation can be finished by board software fully.
The veneer of the embodiment of the invention is realized main, comprising:
Set up communication channel between the plate between each veneer and other veneers;
When the needs masterslave switchover, each veneer is elected from the veneer of applying for main usefulness and is treated the main veneer of use by the mutual negotiation between veneer, and described treating mainly is set to master's usefulness with veneer.
Communication channel between plate is the Communication Layer data-interface, is used for finishing communication between the plate of veneer.Communication channel can be taked network mode between plate, also can adopt the system bus mode, perhaps the data-interface between each veneer.Network mode mainly is applicable to the mutual communication between remote veneer, the system bus mode then is to adopt one or more system bus is set, each veneer all is articulated on the system bus, bus mode simple in structure, be easy to make up, in case shortcoming is a bus failure, then the negotiation between all veneers all can't be finished, and at a time can only transmit the data of a veneer on the general bus.Certainly, these shortcomings of bus mode can utilize the mode that multiple bus is set to be solved.Data-interface between each veneer can be that each veneer all has data-interface with other veneers, can be directly and other veneers carry out data agreement; Also can be that each veneer only has data-interface with the part veneer, and, not have the veneer of data-interface to carry out data agreement with it with other indirectly by the veneer transition of data-interface is arranged with it.And above-mentioned several modes are also non-exclusive, also can adopt wherein two kinds or whole mode simultaneously, and passage is smooth and easy all the time between the plate of assurance veneer.
During negotiation, the negotiation message that each veneer sends mainly comprises: the master is receiveed the response with application with solicitation message, master.Main promptly is the message that veneer application master sends the time spent with solicitation message, with the main usefulness of explanation veneer application.The main response with application promptly is the main response with application made of veneer to other one or more veneer.Response comprises to be agreed to reply or to disagree with and reply, main during with application what agree a certain veneer, sends and agrees to reply, main during with application what disagree with a certain veneer, then sends to disagree with and reply.Veneer can send wherein a kind of in above-mentioned two kinds of negotiation messages, also can two kinds of negotiation messages all send, and for example, a certain veneer sends mainly to be responded with application, disagrees with the main with application of another veneer; And send the main application of using, apply for self using as main.
Each veneer can send negotiation message in turn, applies for that the veneer of main usefulness is judged its main response with application other veneers, when judgement reaches pre-conditioned, determines certainly as treating the main veneer of using.
Pre-conditioned for example can be to agree the answer number threshold value, and it is 10 that this threshold value for example is set.The veneer of applying for main usefulness is mainly judged with response of applying for it other veneers, the response that 10 veneers are arranged in determining other veneers is to agree to reply, that is to say and agree that the quantity of replying has reached agreement answer number threshold value, then determine to be provided with from using as main from as treating the main veneer of using.This mode can be elected the master apace and use veneer, is suitable for carrying out as early as possible the situation of masterslave switchover.
Can be for each veneer be provided with priority, thereby and by the highest veneer of the priority in the veneer of consulting to elect the main usefulness of application between veneer mutually as treating the main veneer of using.For above-mentioned quick negotiation mode, also can priority for agreeing to reply or disagree with the selection principle of replying, promptly judge the veneer priority of the main usefulness of application and be higher than self when veneer, then send and agree to reply, disagree with and reply otherwise send.Certainly, above-mentioned quick negotiation mode has only guaranteed limit priority veneer in the part veneer as main usefulness, but whole limit priority veneer in the veneer not necessarily, a kind of flow process that can elect the limit priority veneer can be carried out as follows:
Each veneer of clock synchronization, and for each veneer distributes sending time slots, each veneer outwards sends data at the sending time slots that is distributed, and monitors the data that other veneers send at other time slots;
Each veneer in turn sends in the following message at least one at the sending time slots that is distributed: application main with, the main of other veneers responded with applying for, wherein, a certain veneer comprises the main response with application of other veneers: whether the veneer priority of judging the main usefulness of application is higher than self, in this way, send and agree to reply, otherwise, send and disagree with and reply, and send main with application;
The veneer of applying for main usefulness is judged its main response with application other veneers, agrees to reply when judging that other veneers all send, and determines from as treating that the master uses veneer.
Because each veneer is higher than self in the veneer priority of the main usefulness of application, send and agree to reply, otherwise send and disagree with and reply, and when disagreeing with, self apply for main usefulness, and all send when agreeing to reply, just determine from using veneer as waiting to lead at other veneers, as seen, this treats that main obviously is the highest veneer of priority with veneer.
The protection turning protocol form that above-mentioned mainboard is switched in can board software realizes.Each veneer carries out the agreement of self separately and calculates and the processing related work.Carry out according to above-mentioned time slot allocation method, it is synchronous at first to carry out system clock, for example for an intersection subsystem, this clock is for intersecting the subsystem internal clocking, every intersection veneer in the intersection subsystem is assigned to a fixing time slot (time slot that each veneer is assigned to is called the sending time slots of this veneer), and in this time slot, veneer gets permission outwards to send data, in other time slot, veneer can only be intercepted communication packet.It mainly may further comprise the steps:
Steps A. each veneer is by communication channel receiving data packets between plate;
Communication channel sends to protocol processes part in the veneer with the data message that receives between the plate of each veneer of step B.;
Step C. protocol processes;
Step D. sends this cross board current state at this veneer time slot, and expectation state (for example apply for main usefulness, i.e. expectation is the main state of using);
Step e. show that when certain time slot has abnormal transmission data of a veneer or data this veneer breaks down, other veneer recomputates activestandby state, can apply for the sending time slots application main usefulness of the veneer wait of main usefulness at oneself.
Step F. every veneer in the intersection subsystem has judged whether the main usefulness of veneer application, if have, judge whether the veneer that this application master uses has higher priority than this plate, if have, then agree to reply in the sending time slots transmission of oneself, higher as this plate priority, then send and disagree with and reply, and send main with application.It should be noted that veneer can all respond with application all before masters, also can only respond previous main with application.This is because in the present embodiment, when a veneer proposes main with after applying for, if there have veneer to propose again to be main with application, the veneer of filing an application after then must have the priority higher than the veneer of filing an application before, thereby the veneer more only need be responded, and back one is main to get final product with application.On the other hand, because when a veneer proposes main with after applying for, if there have veneer to propose again to be main with application, a veneer is disagreed with the main with application of last veneer after then meaning, thereby can integrate with solicitation message and main receiveing the response main with application, be negotiation message can be divided into main with solicitation message (at first propose main with application only for simple main with application, the main of proposition afterwards is not only the main with applying for of this plate with application, also is simultaneously that the main of header board replied with disagreeing with of application) and main with applying for receive the response (only comprise and agree to reply).
Step G. when intersect that all veneers in the subsystem all agree certain piece veneer main with application after, this veneer is determined from mainly use veneer as treating, and self is set to main usefulness.
In veneer quantity more for a long time, can adopt grouping to consult: veneer is divided into a plurality of groupings, each veneer in one group is elected from the veneer of applying for main usefulness and is treated the main veneer of using in the group by mutual negotiation the between veneer, treats in the group that grouping is elected that respectively the master treats that by consulting mutually between veneer to elect the master uses veneer with veneer.Like this, each grouping can be organized interior negotiation separately, and negotiation can be carried out simultaneously in a plurality of groupings group separately.In group, consult to obtain to treat in the group of each grouping main with veneer after, treat mainly to consult between organizing with veneer by these each groupings again, finally negotiate and treat that the master uses veneer.Thereby can accelerate to consult to obtain main speed with veneer.
The veneer of the embodiment of the invention is realized the system of masterslave switchover, establish communication channel between plate between each veneer and other veneers, comprise: the negotiation module of each veneer, be used for by the mutual negotiation between veneer, elect from the veneer of applying for main usefulness and treat the main veneer of use, described treating mainly is set to master's usefulness with veneer.
Each veneer is provided with priority, and described system can comprise:
The time slot allocation module is used for each veneer of clock synchronization, and for each veneer distributes sending time slots, each veneer outwards sends data at the sending time slots that is distributed, and monitors the data that other veneers send at other time slots;
The negotiation module of each veneer, in turn send in the following message at least one at the sending time slots that is distributed: application main with, the main of other veneers responded with applying for, wherein, a certain veneer comprises the main response with application of other veneers: whether the veneer priority of judging the main usefulness of application is higher than self, in this way, send and agree to reply, otherwise, send and disagree with and reply, and send main with application; And
Apply for that the negotiation module of the veneer of main usefulness judges its main response with application other veneers, agree to reply, determine from as treating that the master uses veneer when judging that other veneers all send.
The present invention will be further described below by a concrete application examples.This concrete application examples is applied to intersect in the subsystem, comprises the n piece and intersects veneer, and adopt the time slot allocation method to carry out the auto-negotiation of masterslave switchover.
In this intersected subsystem, public clock generation source was as the fiducial time of intersection subsystem.Each piece veneer in the intersection subsystem all has been assigned with a fixing time slot, and as shown in Figure 1, No. 1 veneer is assigned to time slot No. 1, and No. 2 veneer is assigned to time slot No. 2, and the n veneer is assigned to the n time slot.
Each veneer only can carry out message and send in the own sending time slots that is distributed, in the middle of other time slot, only monitor the message that other veneer sends as monitoring veneer, monitor simultaneously, can write down the state in other veneer message, and according to state computation judge whether needs lead with the application.
As shown in Figure 2, veneer comprises in the handling process of this plate sending time slots:
Under the normal condition, if current single board is a main board, then judge whether to exist fault, if having, then release is led with state and is reported malfunction.
If this plate is a standby board, the current main single board state of using in the judgement system if the master is normal with veneer, then reports the current state of this plate.
If current master is unusual with veneer, need then to have judged whether that veneer applied for main usefulness in advance, if do not have, the main usefulness of this plate application then; If have, will apply for that then board status and this board status relatively, judge whether that this plate priority is higher, if then send main with application; If priority is not applied for plate hight, then report and agree to reply, agree the main of this plate with application.
As shown in Figure 3, veneer comprising in the handling process of this plate monitoring time slot (being other time slots outside the sending time slots):
Veneer is under the monitoring situation, and the type of message that receives has following several:
1, the message of conventional maintenance character.Processing method is to continue to monitor.
2, this veneer (in this example, this veneer promptly refers to send the veneer of message, down together) fault.This situation is divided into following two kinds again:
1) this veneer is a standby board, then writes down this single board default state, continues to monitor.
2) this veneer is that the master uses veneer, judges this board status, if this plate is normal, waits for that application is main with (need wait by the time the sending time slots of this plate just can send main with applying for), if this plate is unusual, continues to monitor.
The main usefulness of 3 these veneer applications.Judge the priority of this veneer, if the main usefulness of veneer application has been arranged before, relatively both priority write down the higher veneer of priority, continue to monitor.
4 listen timeouts think that this veneer is not on the throne, and are consistent with the malfunction processing method.
As shown in Figure 4, switching the handling process collaboration process comprises:
Switch collaborative process and be meant, when mainboard goes wrong, all normal veneers of state can apply for being the main veneer of use in the system, but after needing to consult through all veneers on the throne in the final system, decision is that the master uses veneer by the highest veneer of priority.For the veneer of a certain application master usefulness, have only other veneers to adopt its main using unanimously and apply for that it is main using that this application plate just can switch this board status.
In the example of Fig. 4,6 veneers are arranged in the cross system, wherein No. 4 veneers are the main veneer of using, main in this moment system with priority 1＞2＞3＞5＞No. 6, but No. 1 the highest fault that exists of veneer priority, No. 2 veneer priority is time high and normal, finally switches need be switched on No. 2 veneers.Every veneer handling process is as follows:
No. 4 veneer breaks down, and sends malfunction and discharges main using at sending time slots.
No. 5 veneer time slots detect No. 4 veneer masters with unusual, then send the main message of using of application.
No. 6 veneer time slots detect No. 4 veneer masters with unusual, and No. 5 main usefulness of veneer application, but judge that this plate is working properly lower than No. 5 veneer priority, send and agree to reply.
No. 1 veneer time slot detects No. 4 veneer masters with unusual, and No. 5 main usefulness of veneer application, judges this plate operation irregularity, sends and agrees to reply.
No. 2 veneer time slots detect No. 4 veneer masters with unusual, and No. 5 main usefulness of veneer application, judge the working properly and No. 5 veneer height of priority ratio of this plate, send the application master and use.
No. 3 veneer time slots detect No. 4 veneer masters with unusual, and No. 2 veneers and No. 5 main usefulness of veneer application, judge that the working properly and priority of this plate does not have the veneer height No. 2, sends and agrees to reply.
No. 4 veneer time slots, No. 2 main usefulness of veneer application are judged this plate operation irregularity, send to agree to reply.
No. 5 veneer time slots detect No. 4 veneer masters with unusual, and No. 2 main usefulness of veneer application, judge that this plate is working properly but do not have veneer priority height No. 2, send and agree to reply.
No. 6 veneer time slots detect No. 4 veneer masters with unusual, and No. 2 main usefulness of veneer application, judge that the working properly and priority of this plate does not have the veneer height No. 2, sends and agrees to reply.
No. 1 veneer time slot detects No. 4 veneer masters with unusual, and No. 5 main usefulness of veneer application, judges this plate operation irregularity, sends and agrees to reply.
No. 2 veneer time slots, it is the highest to detect main usefulness of this plate application and priority, and switching current state is the main state of using.
The present invention is with respect to other main and standby rearranging method of the prior art, do not need to control veneer, service board, hardware participation, do not take traffic overhead, determine the main veneer of using by the auto-negotiation between veneer fully, simple in structure, upgrading is convenient, and for example for the existing subsystem that intersects, the board software that only needs to upgrade can be realized.
This method also has very strong autgmentability in addition, is not limited to the cross protection of fixed proportion, supports the protection of n: m, and n and m can not cause the major change in the system according to the system requirements setting, for a kind of easy method is provided at the net System Expansion.
More than be to be example to intersect the class veneer, obviously, this method is not limited to active/standby switching of cross-connect board; for other service class veneer, monitoring class veneer; also can adopt, this method realize 1+1 protection switch, 1: the n protection is switched, n: m protection is switched, and its application scenarios is numerous.
Above content be in conjunction with concrete execution mode to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
