(1) webmaster replacing or network management data are lost;
(2) network element has imported new configuration by network management interface;
(3) changed the configuration of network element by concole mouth or telnet;
When (4) webmaster establishment, modification, deletion net element information, network link is unusual, makes configuration normally not issue;
When (5) webmaster does not link to each other with network element, the pre-configured network element of webmaster.
Above-mentioned situation all can cause network element and network management data inconsistent, makes the user can not see the real information of equipment and has carried out wrong operation.
In view of above situation, must can realize data synchronization between webmaster and the network element, to guarantee the consistency of configuration up and down, this just requires will preserve in the webmaster backup of network element data, can obtain the other side's configuration between webmaster and the network element by certain operation.
When webmaster or network element have the arrangement abnormalities of an end, the data that just need synchronizing network management and network element, but, a kind of detailed data configuration is described, need to use the binary number of consecutive, the configuration of necessary each object of poll of webmaster or network element, and each configuration item is compared by turn, find out not existing together of configuration, perhaps directly that data are all synchronous, thereby the renewal self database, this is the engineering of a very consuming time and poor efficiency.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned background technology the method that provide a kind of and save time, reliably and efficiently network element and webmaster is realized configuration synchronization.
Network element provided by the invention and webmaster are realized the method for configuration synchronization, may further comprise the steps: steps A, every mode that is configured to order ID of network element is carried out unique identification, there is the configuration item of order ID to be loaded in each network element sign, be sequence number of each order ID configuration, the configuration information of each network element is kept in the reference table of main control unit; Step B, initiate synchronously or webmaster is initiated when synchronous to network element to webmaster when network element, configuration item to each network element of preserving in network management data storehouse and the main control unit reference table compares, configuration items different in the comparative result is added in the configuration distributing formation, prepare data synchronization; Step C, employing subpackage and compressed package mode send and receive synchronization packets.
In technique scheme, the subpackage mode among the step C is: when the synchronous network element of webmaster, behind each the big bag decompress(ion) with webmaster, by the configuration synchronization agreement each configuration order bag is separated from big bag, after each network element receives the configuration of self, extract order ID, cover original configuration.
In technique scheme, the compressed package mode among the step C is: when the network element synchronizing network management, the configuration of a plurality of order ID that will obtain from network element is spliced into big bag, mails to webmaster after big bag is compressed.
In technique scheme, when network element or webmaster are made amendment to configuration item in the steps A, sequence number added 1 operation.
In technique scheme, configuration information described in the steps A comprise single-deck information on the throne, and single-deck or single-deck hang the data configuration of optical network unit ONU down.
In technique scheme, the information on the throne of described single-deck is carried out when synchronous, webmaster is inquired about the network element information on the throne of current system, and according to Query Result analysis disc situation on the throne, if the groove position is all consistent with disc-type, then webmaster does not process; If only there is the configuration information of single-deck, but do not have the information on the throne of this dish, then webmaster increases the information on the throne of this dish; If dish is on the throne on the groove position, and has configuration information, but disc-type is inconsistent, then webmaster is replaced disc-type; Whether webmaster coils synchronizing information on the throne with each groove position and the action that will take shows, select will carry out synchronously for the user.
In technique scheme, described data configuration is carried out when synchronous, the check that network element and webmaster at first are configured, after webmaster issues Query Information, network element is with object in the ergodic data and order ID, obtain the sequence number of order ID, and, return to webmaster and compare the address of network element object, order ID that this object is supported and the sequence number of this ID correspondence; The webmaster corresponding order ID configuration data sequence number in the reading database that receives orders behind the ID, the sequence number of more same configuration, if the sequence number of storing in the sequence number uploaded of network element and the network management data storehouse is identical, then judge this configuration consistency, otherwise webmaster shows the difference configuration by network management interface.
In technique scheme, described webmaster is initiated when synchronous to network element, after network element receives the synch command of webmaster, sequence number is enclosed in the single configuration that needs synchronization object sent to webmaster together, and webmaster is new database more.
In technique scheme, when carrying out configuration synchronization, webmaster resolves into many order ID and object with synch command, inform that network element needs synchronous configuration, network element is preserved to read the module from configuration needs synchronous configuration, obtain the sequence number of order ID again from the reference table module, the sequence number of configuration that needs are synchronous and order ID sends to the Buffer Pool of subpackage-compressed package module, and subpackage-compressed package module sends to webmaster obtain the set of configuration data bag from Buffer Pool after.
In technique scheme, after webmaster receives configuration data, according to following three kinds of situations new database more: if there is not this configuration in the object in a network management data storehouse, then increase this configuration, and be the sequence number that network element transmits with sequence number update; If there is this configuration in the object in the b network management data storehouse, but the sequence number of this item and the sequence number in the network element are inconsistent, then revise the configuration in the database, and are the sequence number that network element transmits with sequence number update; If there is a certain configuration in the object in the c network management data storehouse, but does not have this configuration in the configuration of network element, then webmaster deletes this configuration, and is the sequence number that network element transmits with sequence number update.
The present invention is configured to unique mode with network element every and identifies, each network element configuration information stores is in the reference table of main control unit, when webmaster and each network element relatively dispose, only need read reference table information in the main control unit, one by one all configuration orders of retaking of a year or grade network element.When needs are synchronous, the user issues simultaneous operation by network management interface, webmaster compares the information of configuration information in the database and reference table by certain mode, and comparative result shown by network management interface feed back to the user, the user can carry out following optionally operation: (1) network element that single configuration is different carries out uploading or downloading of data; (2) all are different configurations are uploaded or are downloaded; (3) no matter whether configuration is identical, network element and network management data library information are uploaded or downloaded.
Compared with prior art, advantage of the present invention is as follows:
(1) the present invention adopts order ID to identify concrete configuration, represents webmaster and network element to store the variable condition of this configuration with sequence number, and the configuration that can locate network element and webmaster does not fast exist together.
(2) adopt the mode of subpackage and compressed package to carry out uploading and downloading of data among the present invention, reduced the number of interaction data bag between webmaster and the network element, reduce the link burden effectively, can transmit fast and effectively needs synchronous configuration data, saves time, reliably and efficiently realizes the configuration synchronization between network element and the webmaster.

Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Network element that the embodiment of the invention provides and webmaster are realized the method for configuration synchronization, may further comprise the steps:
Steps A, every mode that is configured to order ID of network element being carried out unique identification, have the configuration item of order ID to be loaded in each network element sign, is sequence number of each order ID configuration, and the configuration information of each network element is kept in the reference table of main control unit;
Step B, initiate synchronously or webmaster is initiated when synchronous to network element to webmaster when network element, configuration item to each network element of preserving in network management data storehouse and the main control unit reference table compares, configuration items different in the comparative result is added in the configuration distributing formation, prepare data synchronization;
Step C, employing subpackage and compressed package mode send and receive synchronization packets.Concrete, when the synchronous network element of webmaster, behind each the big bag decompress(ion) with webmaster, each configuration order bag is separated from big bag by the configuration synchronization agreement, after each network element receives the configuration of self, extract order ID, cover original configuration; When the network element synchronizing network management, the configuration of a plurality of order ID that will obtain from network element is spliced into big bag, mails to webmaster after big bag is compressed.
The specific implementation step of the embodiment of the invention is as follows:
1, with the command id configuration item and be loaded in each network element:
Embodiment of the invention utility command ID (IDentity, the identify label number) comes certain concrete configuration of unique identification, when authorizing certain object (dish or optical network unit ONU), inquire about this object according to the type of this object and support which configuration item, and the configuration item of being supported loaded, for example the order that need load of main control unit comprises: M-VLAN (Virtual Local Area Network, VLAN), NGN (Next Generation Network, next generation network) first line of a couplet user data and PON mouth performance statistics enable switch etc., and the order that first line of a couplet dish need load has first line of a couplet dish masterslave switchover enable switch and the inhibition of designated port bag etc.When webmaster and network element are configured comparison, whether synchronous order ID will must dispose a important indicator as difference network element and webmaster.
2, be order ID configuration sequence number (seqId):
Each network element has loaded the configuration order that can support, when webmaster and network element are configured comparison, even result relatively is that both sides preserve this configuration item, can't confirm but whether configuration is identical.Therefore, the embodiment of the invention is distributed a sequence number for each order ID, and this sequence number can be discerned simultaneously by webmaster and network element.Though network element or webmaster in which way to configuration item create, change, operation such as deletion, in operating successfully, all to add 1 operation to sequence number.
When the user carries out singlely when issuing the operation of configuration to network element by webmaster or order line, object, order ID and the sequence number of operation should be write in the reference table, write down the configuration information of this object.
3, the comparison of webmaster and network element data:
When network element is initiated synchronously or webmaster is initiated when synchronous to network element to webmaster, at first be configured comparison, entity relatively is the configuration item of each object of preserving in network management data storehouse and the main control unit reference table, then configuration items different in the comparative result is added in the configuration distributing formation, prepare data synchronization.
4, the transmission of synchronization packets and reception:
If in webmaster and the network element to dispose more needs synchronous, and synchronizing process is to issue configuration one by one, webmaster or network element must be waited until a configuration distributing success so, take out next configuration again from deployment queue, thereby new database more.Can increase the mutual time of webmaster and network element data so undoubtedly, the embodiment of the invention adopts data is packaged and the processing mode of compressed package, when the packet of group bag carries out subpackage during greater than 8K and compression is handled.
When the synchronous network element of webmaster, behind each the big bag decompress(ion) with webmaster, each configuration order bag is separated from big bag by the configuration synchronization agreement, after the network element object receives and belongs to the configuration of self, extract order ID, cover original configuration; When the network element synchronizing network management, need the configuration of a plurality of order ID that will obtain from network element to be spliced into a big bag, mail to webmaster after the compression.
Configuration information had both comprised the information on the throne of single-deck, comprise again and hang ONU (Optical Network Unit under single-deck or the single-deck, optical network unit) data configuration, because synchronizing process is divided into following two stages: the information on the throne of stage 1, synchronous OLT (Optical Line Tterminal, optical fiber cable termination equipment) dish; The configuration data of stage 2, synchronous disk.
Respectively stage 1 and stage 2 are elaborated below.
Stage 1, dish are in bit synchronization:
(1) webmaster is to the network element of the current system of equipment query information on the throne, according to the information analysis dish situation on the throne that receives, and more different information, if the groove position is all consistent with disc-type, then webmaster does not process; If the configuration information of single-deck is arranged, but the information on the throne that should not coil, and then webmaster increases the information on the throne of this dish; If dish is on the throne and configuration information is arranged on the groove position, but disc-type is inconsistent, then webmaster carries out disc-type and replaces.
Whether (2) webmaster synchronizing information that each groove position dish is on the throne and the action that will take adopt the mode of tabulation to show, select will carry out synchronously for the user.If the user confirms that then the action by row in the table continues operation; Operate like this if the user not thinks, then cancel the current command, otherwise, will increase as required or after modification coils information on the throne, be configured again synchronously.
Stage 2, data configuration are synchronous:
The initiation of configuration synchronization is moved no matter upload or download, the check that network element and webmaster at first are configured, and referring to shown in Figure 1, the flow process of check is as follows:
After webmaster issued Query Information, network element obtained the sequence number of order ID with object in the ergodic data and order ID, and with the address of network element object, order ID that this object is supported and the sequence number of this ID correspondence, returned to webmaster and compare.The webmaster corresponding order ID configuration data sequence number in the reading database that receives orders behind the ID, the sequence number of more same configuration, if network element upload with the network management data storehouse in store identical, then think this configuration consistency, otherwise webmaster shows the difference configuration by network management interface.
Whether webmaster and network element canned data be consistent shows by webmaster, and the user can carry out uploading or downloading of data as required.
In the check of above-mentioned data, if single webmaster repeats to issue, the sequence number of webmaster and network element can increase simultaneously, and there is not inconsistent situation in sequence number.If multiple network management, when a plurality of webmasters issued identical configuration continuously, the sequence number of network element can repeatedly add 1 action, but the actual disposition of network element does not change, and thought still during check that webmaster and equipment disposition are inconsistent.Therefore the embodiment of the invention adopts the configuration of reading network element before webmaster issues configuration earlier, the different sequence numbers of just revising network element of configuration.
Uploading of data is to use the network element synchronizing network management, and downloading then is with the synchronous network element of webmaster.
Referring to shown in Figure 2, the flow process of network element synchronizing network management is as follows:
After network element has received webmaster and needs synchronous order, network element will be enclosed sequence number to the single configuration that needs synchronization object and send to webmaster together, and webmaster is new database more.
Detailed process is as follows:
(1) when carrying out configuration synchronization, synch command (may be made up of many order ID) need be resolved into many order ID and add object, inform which configuration of network element need carry out synchronously, network element is preserved the module from configuration and is read these configurations, obtain the sequence number of these orders ID again from the reference table module, and these information are sent to the Buffer Pool of subpackage-compressed package module.
(2) subpackage-compressed package module sends to webmaster obtain the set of configuration data bag of some from Buffer Pool after.When the size of packet is compressed during greater than 8K, the form of compressed package is referring to shown in Figure 3, wherein to be used for distinguishing be read operation or write operation to command type, order length is payload user data length, the sequence number of order subpackage is since 1 counting, the number of subpackage represented by a byte, and whether the sequence number by relatively subpackage and the number of subpackage come the judgment data bag all to send to finish.When the compression flag bit of packet is 0XB5B5B5B5, show that this packet compresses, be to represent not compress in 0 o'clock.Similarly, compression section also comprises the sequence number and the number of compressed package.The method of employing group bag, subpackage and compressed package can will be compressed and subpackage less than the data of 400K, has reduced the number of data packet transmission on the link, the bigger time that shortens configuration synchronization.
(3) after webmaster receives configuration data, according to following three kinds of situations new database more:
If not this configuration of the object in a network management data storehouse then increases this configuration, and be the sequence number that network element transmits with sequence number update.
If the object in the b network management data storehouse has this configuration, but the sequence number of configuration item and the sequence number in the network element are inconsistent, then revise the configuration in the database, and are the sequence number that network element transmits with sequence number update.
If the object in the c network management data storehouse has a certain configuration, but does not comprise this configuration in the configuration of network element, then webmaster deletes this configuration, and is the sequence number that network element transmits with sequence number update.
The configuration sequence number form by 4, from 0～15, webmaster and network element all adopt from 0～15 the circulation mode.When the configuration of network element is to have when being imported by customized configuration, can not check directly all data synchronously, then webmaster and network element should synchronously be initialized as 0 with sequence number.
Referring to shown in Figure 4, the idiographic flow of the synchronous network element of webmaster is as follows:
Because the main control unit in the network element is divided into master and is equipped with dish, so the synchronous network element of webmaster will carry out with being equipped with in the dish simultaneously at master.Webmaster issues synchronous process and webmaster, and to issue the process of configuration similar.Difference for configuration just at single object, and the synchronous network element of webmaster to be a plurality of configurations with a plurality of objects package issues each network element respectively.The configuration packet that the subpackage of network element-the compressed package module is sent webmaster is decomposed into order one by one, and resolves to the configuration of single network element.Webmaster is given each network element with these configuration distributings, if network element runs succeeded, then returns success order and gives webmaster, and sequence number is added 1 operation.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
