Description
Technical field
The present invention relates to the communication technology, particularly the switching technique in the communication equipment.
Background technology
Communication network requires and can provide reliable continual service for its user, especially in the application of some important service, as electronic money, order processing, customer service, stock control, Email and Internet access etc., professional survivability becomes than more important in the past, and its availability requirement can reach 99.999% even higher.Therefore, the network survivability ability becomes the key factor that influences network design and structure, and the equipment that uses in communication network also needs very high reliability accordingly.
In communication system, redundancy backup and load sharing are the methods of the enhancing equipment dependability used always.Redundancy backup is meant and adopts the equipment of a plurality of identical functions to carry out replacement work that particularly under breaking down the situation that maybe needs to safeguard when host apparatus, stand-by equipment is taken over host apparatus and proceeded communication, guarantees the not interrupt run of communication system.Load sharing adopts identical principle, utilizes the alternation or the collaborative work of a plurality of equipment, increases the reliability of system.
For the assembly that adopts redundancy backup, the mechanism that masterslave switchover must be provided is to realize the demand of reliability and maintainability.Redundancy backup and masterslave switchover technology have multiple backup mode, such as 1+1, and 1: 1,1: N etc.1+1 backup is a kind of simple protected mode; active and standby in the system formed a service functional unit in logic with the unit; be that protected unit has a stand-by unit; the main real-time processing of being responsible for business with module; standby professional the maintenance and main data consistent with the unit; detect former main during with cell failure initiation switch, take over former master with the business on the unit.Stand-by unit is only started working after breaking down in the backup in 1: 1 different with 1+1 backup.And 1: the N backup is exactly that a plurality of units are shared a stand-by unit, and when any one master was broken down with the unit, stand-by unit was promptly taken over its work.
Usually, the telecommunication apparatus of a complexity comprises a plurality of processing unit collaborative works, needs to communicate between each unit; And in whole communication network, also need communication between the different node devices.In order to guarantee under network fault conditions the equipment self-healing ability, to guarantee the integrality of data and keep service quality, switch and must in the time limit of appointment, finish, recover professional as early as possible, make the communication system influence minimum.In general, be same functional entity each other on the component logic of active and standby usefulness, have only the master externally to provide service during operate as normal with the unit, stand-by unit does not externally provide service but needs and is consistent with main data with the unit as far as possible, after guaranteeing that the master is upgraded to main using with cell failure is standby, traffic lost is minimum.And these functions are all closely related with the performance of the switching technique that is adopted.Therefore, the performance of wrap protection all has great influence for the reliability of system and even the survival ability of whole network.
According to the reason difference of switching triggering, can be divided into Manual Switch, automatic fault is switched and automaticmanual is switched etc.Wherein, Manual Switch is meant by maintenance console to send the artificial triggering masterslave switchovers of mode such as switching order by operating personnel; Automatic fault is switched, and is meant by the system failure detection module, and detect the master and break down with veneer, and by the automatic masterslave switchover that triggers of system; Automaticmanual is switched, be meant because the main peripheral modules that relates to veneer takes place unusual or owing to mainly will be pulled out or because the specific (special) requirements of some veneer with veneer, and need stop using a period of time to safeguard with veneer with main, and the active and standby plate after taking place to switch also needs to switch back original main and standby relation, in this case the masterslave switchover that triggers automatically of the system of Fa Shenging.
In the present communication system, active and standby identity with the unit is determined that by bottom hardware when hardware found that the master uses unit exception, stand-by unit was upgraded to main using immediately, and then the notice upper application module, and further notify relevant other veneer that active and standby plate switching has taken place.
Fig. 1 shows the structure of a kind of exchanging system that is adopted in the existing communication system.The master uses, stand-by unit is connected by other equipment of circuit handover module and communication system.The circuit switching module realizes by switching network, and in the ordinary course of things, switching network is to finish switching by the exchange of active and standby physical address with the unit.Each Service Processing Unit all keeps physical connection with active and standby crosspoint.When switching condition trigger equipment unit and switch, bottom hardware carries out circuit and switches, and stand-by unit is switched on the working face, mainly separates with the unit, notifies all upper application module, business module to communicate by letter with the unit with new master then.
As seen, the present switching technique that is adopted in the communication system, owing to active and standby arbitration, switch notice etc. and all directly undertaken by bottom hardware, upper application module and business module are in passive state, are unfavorable for high-rise plant maintenance; And because to switch be directly to be realized by circuit switching, therefore upper layer application is not had the transparency, switch system is impacted bigger; Once more, reversed process is mechanically finished by circuit, does not have flexibility, can not support automaticmanual to switch; In the ordinary course of things, also need during device switching to carry out reconfiguring of data transfer, stand-by equipment etc., need long time delay, cause in communication network, can not satisfying the demand of real time business, high quality-of-service far away.
In actual applications, there is following problem in such scheme: because device switching is initiated and carried out by bottom hardware, upper layer application is in passive treatment state, safeguards for high-level device and does not support; Because the active and standby more time of consumption that reconfigures with data transfer and stand-by equipment between the equipment, so the switching operation time-delay is big, can not satisfy real-time requirement; Switch realization owing to switch, do not have the transparency and flexibility by physical address conversion or circuit, therefore bigger for the influence of whole communication system.
Cause the main cause of this situation to be, the device switching in the existing communication system is to realize by the physical operations that bottom hardware is initiated, and active and standbyly only carries out data with the unit when switching and shift and dispose.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention adopts the step-by-step procedure under the control to finish reversed process, and whole switching operation logically is divided into a plurality of substeps, improves the flexibility of switching operation.To carry out function and separate, realize by Executive Module and control module respectively with controlled function.Utilize the transparency of the mapping realization switching operation of logical address and physical address, minimum is reduced in the influence of switching whole communication system.Adopt the warm spare mechanism of data, keeps active and standby with between the unit synchronously, improve the speed of execution masterslave switchover.Adopt the traffic smoothing processing method, when guaranteeing to switch to the traffic smoothing transition.
Fig. 2 shows the structure of exchanging system according to an embodiment of the invention, comprises control module 201, main with Executive Module 202 and standby Executive Module 203.Wherein, control module 201 is used to control the execution of switching step, all links to each other with standby Executive Module 203 with Executive Module 202 with main; Main with Executive Module 202 be used under the control of control module 201 main with veneer on execution switch step; Standby Executive Module 203 is used for switching step controlled the execution down of control module on standby board.Wherein the master is distributed in the master with on the veneer with Executive Module 202, and standby Executive Module 203 is distributed on the standby board.And that control module 201 can be distributed in is active and standby with on the veneer, also can be distributed in separately on the other veneer.Controlled function and execution function are separated into independently module, make switching operation to realize set by step, strengthened the reliability and the flexibility of switching, make to switch and to carry out rollback set by step.
Fig. 3 shows the Address Mapping in the exchanging system according to an embodiment of the invention.At first to each veneer definition logical address and physical address.Use logical address to communicate between the application layer module, have address mapping relation between logical address and the physical address, this address mapping relation is safeguarded by the bottom module.When switching, the mapping relations between bottom module switch logic address and the physical address have promptly realized transparent switching.
Such as, comprise equipment veneer A, equipment veneer B and standby board B ' thereof in the communication system.When operate as normal, board B is the main veneer of using, board B ' be standby board, the physical address of board B is 301, board B ' physical address be 302.By map addresses, the physical address 301 of board B is corresponding with logical address 303, board B ' physical address 302 corresponding with logical address 304.Other veneers in the communication system such as veneer A, by the main veneer of using of logical address 303 visits, communicate with board B with main.When switching when taking place, Address Mapping is switched address mapping relation, and main physical address 301 with board B is mapped to logical address 304, and the physical address 302 of standby board B ' is mapped to logical address 303.After this during other veneer A access logic addresses 303, promptly visit physical address 302 pairing veneers, therefore be actually and board B ' communicate by mapping relations.At this moment board B ' become is main uses veneer, and board B becomes standby board.And before and after whole switching operation takes place, upper application module, or other veneers all are not affected.
Adopt above-mentioned Address Mapping, realize the switching of bottom communication passage fast, realized the fast processing of switching, and reduce service outage duration.Do not switch because the operation of address mapping relation does not relate to hardware, therefore improved the reliability of switching operation.Simultaneously,, shielded and switched the influence that brings, had the transparency for other business module.
Fig. 4 shows reverse method flow process according to an embodiment of the invention.According to aforementioned, will switch flow process and be divided into a plurality of steps execution, and finish controlled function by control module, Executive Module is finished concrete operations.
Under various triggering modes, after switching triggering, trigger message and at first pass to control module, start switching operation by control module.
At first enter step 401, switch preliminary treatment, judge whether system resource satisfies the condition of switching by control module.Just because switching operation needs certain system resource condition to finish, therefore switch carry out before, in order to guarantee the reliability of switching, carry out system resource earlier by control module and judge.Such as, judge whether the configuration of standby board finished that if also not configuration of standby board then can't be taken over the master and communicate with veneer, switching operation can not carry out, this moment, control module was switched flow process with termination.For the situation of Manual Switch, control module will judge that also system resource is whether sufficient, such as when the standby board operation exception, send warning signal, and notification operator can not be switched.
Then enter step 402, control module sends order and switches preliminary treatment by the master with Executive Module and standby Executive Module with Executive Module and standby Executive Module to main, judges whether service resources satisfies the condition of switching.Because switching operation has certain influence to business, therefore before switching, must judge the current business of moving by Executive Module, such as, busier or during when business to the having relatively high expectations of real-time, judge that the condition of switching does not satisfy, stop switching or postponing and switching, perhaps send and switch unsafe warning.
Then enter step 403, after the condition of switching satisfies, carry out the business datum back-up processing with Executive Module and standby Executive Module by main.Because standby board and master can not be synchronous with data between the veneer, even adopt the mode of warm spare can not guarantee the synchronous fully of data, therefore before switching real execution, the data that need will lead with veneer earlier backup to standby board, make active and standby in full accord with data, guarantee that after switching generation service communication can smoothly continue.
Then enter step 404, under control module control, finish hand-off process to the bottom communication passage, the i.e. address mapping relation of logical address and physical address modification with Executive Module and standby Executive Module by main.Former main logical address with veneer is mapped on the physical address of former standby board.This step has been finished active and standby transparent switching with veneer, has shielded the influence to higher layer applications module and other uncorrelated veneers, and can finish in the time faster.
Then enter step 405, under control module control, finish the configuration data hand-off process relevant with Executive Module and standby Executive Module with system by main.In communication system, equipment veneer often needs to be configured could operate as normal, therefore switch finish after, also need to carry out the relevant configuration data of system and handle.Such as, need dispose active and standby state at bottom with veneer, make the winner no longer send data, and other veneers of standby board and system communicate with veneer.
Enter step 406 at last, by the main smoothing processing of finishing business datum with Executive Module and standby Executive Module.Active and standby finish with veneer switch after, need to guarantee smoothly continuing of communication service, therefore in this step, Executive Module is monitored active and standby communication service with veneer, and adopt corresponding strategy under special circumstances, to guarantee the professional influence that is not subjected to switching operation as far as possible.Such as, communication data to standby board is verified, if communication occurs unusual, then send warning signal, perhaps work simultaneously with veneer and standby board traffic smoothing phase master, when active and standby usefulness veneer data are synchronous fully, just use the data of standby board to communicate, and make the winner enter stand-by state with veneer.
In one embodiment of the invention, under unnecessary situation, in the flow process of above-mentioned reverse method, step 402 is omitted.Such as, under the auto switching that hardware fault causes, this moment, the master was broken down with veneer, must take over it by stand-by unit communicates, the influence that cause business this moment is inevitable, but because the active and standby business datum of moving with veneer is designed to the warm spare mode, reality also can be very little to the influence of business.
In another embodiment of the present invention, under unnecessary situation,, in the flow process of above-mentioned reverse method, step 403 is omitted as the auto switching that hardware fault causes.Because during hardware fault, the master breaks down with veneer, can not switch recovery operation, so configuration data there is no need to back up.
In one embodiment of the invention, in order to realize smoothly switching design, as the veneer of master-slave redundancy backup, adopt the warm spare mode, assurance data sync and traffic smoothing are switched.Warm spare is meant, in normal course of operation, when the business datum on the mainboard changes, immediately business datum is backuped on the slave board, makes the service data on the main and standby boards remain unanimity.And when switching, particularly switch down at Manual Switch or automaticmanual, allow the master business datum to be backuped on the standby board with veneer, owing to implemented warm spare during operate as normal, therefore when switching generation, required backed up data amount is very little, and data backup institute time-consuming also is fewer, improve the speed switch thus, reduce the influence that system and service communication are caused.
In one embodiment of the invention, also utilize the step manner of execution of switching flow process to realize switching recovery.Switch within the certain hour after recovering to be meant in switching process of transmitting or switching generation, recovery can according to circumstances be switched by system, makes active and standbyly to return to state before switching with veneer as far as possible.This has realized the support of switching for automaticmanual under some special requirement situation, such as the board switchover process of being initiated by the Operation and Maintenance personnel, need carry out the off-line operation of certain hour with veneer to main.
Reverse method according to an embodiment of the invention at first will be switched flow process and be divided into a plurality of stages, adopt the method for State Control to control the carrying out of switching.When any one stage, the appearance processing was unusual, can switch and recover to handle, return to the state before switching as far as possible.Provided in detail below in switching step, when abnormal conditions occurring, switched that to recover flow process as follows:
In step 401 or the step 402,, owing to also do not carry out the switching operation of essence,,,, will directly finish to switch flow process, not need to switch recovery such as switching condition judgment when not satisfying if switch failure therefore in this stage at the pretreatment stage of switching.
In the step 403, in the data backup stage, because data backup does not influence former main normal operation with veneer, be at standby board with data backup, when therefore switching failure, the recovery operation of carrying out of switching only needs standby board is recovered, and restarts such as simply standby board being resetted.
In the step 404, in bottom communication passage switch step, if unusual, then switch recovery operation, the bottom communication passage is switched the state that returns to before switching, and recover former main configuration with veneer, notify it to move with veneer as main.
In the step 405, in system's relevant configuration data switch step, if it is unusual, then switch recovery operation, recovering the relevant configuration data earlier is former active and standby corresponding relation, then the bottom communication passage is switched the state that returns to before switching, recover the former main business module of using veneer etc. at last, notify it to move with veneer as main.
In one embodiment of the invention, by above-mentioned system's smooth upgrade and the hardware maintenance of switching Restoration Mechanism realization non-interrupting service.Such as, adopt and switch recovery, can from system, unload a period of time with veneer with main, operate or safeguard,, recover main operation again with veneer then by switching Restoration Mechanism, move with veneer and substitute the master by standby board in this course, so business is not interrupted.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
