Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The network element that the embodiment of the present invention provides and webmaster are realized the method for configuration synchronization, comprise the following steps:
Steps A, every mode that is configured to order ID of network element is carried out to unique identification, have the configuration item of order ID to be loaded in each network element mark, for a 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 synchronous or webmaster when network element to webmaster and initiate when synchronous to network element, configuration item to each network element of preserving in network management data storehouse and main control unit reference table compares, configuration items different in comparative result is added in configuration distributing queue, prepare the synchronous of data;
Step C, employing subpackage and compressed package mode are carried out sending and receiving to synchronization packets.Concrete, in the time of the synchronous network element of webmaster, by after each large bag decompress(ion) of webmaster, by configuration synchronization agreement, each configuration order bag to be separated from large bag, each network element receives after the configuration of self, extracts order ID, covers original configuration; In the time of network element synchronizing network management, the configuration of the multiple order ID that obtain from network element is spliced into large bag, after being compressed, large bag mails to webmaster.
The specific implementation step of the embodiment of the present invention is as follows:
1, with command id configuration item and be loaded in each network element:
Embodiment of the present invention utility command ID (IDentity, identify label number) carry out certain concrete configuration of unique identification, in the time 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 supported configuration item is loaded, the order that for example main control unit need to load 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 upper united dish need to be loaded has upper united dish masterslave switchover enable switch and the inhibition of designated port bag etc.In the time that webmaster and network element are configured comparison, whether synchronous order ID will must configure 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 if result is relatively that both sides preserve this configuration item, cannot confirm but whether configuration is identical.Therefore, the embodiment of the present invention is that each order ID distributes a sequence number, and this sequence number can be identified by webmaster and network element simultaneously.Though network element or webmaster in which way to configuration item create, change, the operation such as deletion, in operating successfully, all to add to sequence number 1 operation.
In the time that user carries out the single operation that issues configuration by webmaster or order line to network element, the object of operation, order ID and sequence number should be write in reference table, record the configuration information of this object.
3, the comparison of webmaster and network element data:
Initiating synchronous or webmaster when network element to webmaster initiates when synchronous to network element, first be configured comparison, entity is relatively the configuration item of each object of preserving in network management data storehouse and main control unit reference table, then configuration items different in comparative result is added in configuration distributing queue, prepare the synchronous of data.
4, the sending and receiving of synchronization packets:
If in webmaster and network element to dispose more needs synchronous, and synchronizing process is to issue one by one configuration, webmaster or network element must be waited until a configuration distributing success so, then from deployment queue, take out next configuration, thereby new database more.Can increase so undoubtedly the interaction time of webmaster and network element data, the embodiment of the present invention adopts data is packaged and the processing mode of compressed package, carries out subpackage and compression is processed in the time that the packet of group bag is greater than 8K.
In the time of the synchronous network element of webmaster, by after each large bag decompress(ion) of webmaster, by configuration synchronization agreement, each configuration order bag to be separated from large bag, Network element object receives and belongs to after the configuration of self, extracts order ID, covers original configuration; In the time of network element synchronizing network management, the configuration of the multiple order ID that obtain from network element need to be spliced into a large bag, after compression, mail to webmaster.
Configuration information had both comprised the information in place of single-deck, comprise again and under single-deck or single-deck, hang ONU (Optical Network Unit, optical network unit) data configuration, because synchronizing process is divided into following two stages: the information in place 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 information in place of equipment query current system, according to the information analysis dish situation in place receiving, and more different information, if groove position is all consistent with disc-type, webmaster does not process; If there is the configuration information of single-deck, but the information in place of this dish not, and webmaster increases the information in place of this dish; If coil in place on groove position and have configuration information, but disc-type is inconsistent, webmaster carries out disc-type replacement.
(2) whether webmaster coils synchronizing information in place by each groove position and the action that will take adopts the mode of list to show, select will carry out synchronous for user.If user confirms, continue operation by the action of row in table; Operate like this if user not thinks, cancel the current command, otherwise, will increase as required or amendment is coiled after information in place, then be configured synchronous.
Stage 2, data configuration are synchronous:
The initiation of configuration synchronization is moved no matter upload or download, the check that first network element and webmaster are configured, and shown in Figure 1, the flow process of check is as follows:
Issue after Query Information at webmaster, network element, by the object in ergodic data and order ID, obtains the sequence number of order ID, and the order ID that the address of Network element object, this object are supported and sequence number corresponding to this ID, returns to webmaster and compares.The webmaster corresponding order ID configuration data sequence number in reading database that receives orders after ID, the sequence number of more same configuration, if network element upload with network management data storehouse in store identical, think this configuration consistency, otherwise webmaster shows difference configuration by network management interface.
Webmaster shows by webmaster with whether network element canned data is consistent, and 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 sequence number does not exist inconsistent situation.If multiple network management, in the time that multiple webmasters issue 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 still thinks that webmaster and equipment configuration are inconsistent when check.Therefore the embodiment of the present invention adopts the configuration of first reading network element before webmaster issues configuration, the different sequence numbers of just revising network element of configuration.
Uploading of data is to use network element synchronizing network management, and downloading is with the synchronous network element of webmaster.
Shown in Figure 2, the flow process of network element synchronizing network management is as follows:
Network element has received webmaster to be needed after synchronous order, and network element sends to webmaster together by the single configuration that needs synchronization object is enclosed to sequence number, and webmaster is new database more.
Detailed process is as follows:
(1) in the time carrying out configuration synchronization, synch command (may be made up of many order ID) need to be resolved into many order ID and add object, inform which configuration of network element need to carry out synchronously, network element is preserved module and is read these configurations from configuration, obtain again the sequence number of these orders ID from 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.In the time that being greater than 8K, the size of packet compresses, the form of compressed package is shown in Figure 3, wherein command type is read operation or write operation for distinguishing, order length is payload user data length, the sequence number of order subpackage is since 1 counting, the number of subpackage is represented by a byte, by relatively the sequence number of subpackage and the number of subpackage judge whether packet is all sent.In the time that the compression flag bit of packet is 0XB5B5B5B5, show that this packet compresses, be to represent not compress for 0 o'clock.Similarly, compression section also comprises sequence number and the number of compressed package.The method of employing group bag, subpackage and compressed package, can compress the data that are less than 400K and subpackage, has reduced the number of data packet transmission on link, the larger time that shortens configuration synchronization.
(3) webmaster receives after configuration data, according to more new database of following three kinds of situations:
If not this configuration of the object in a network management data storehouse, increases this configuration, and be the sequence number that network element transmits by sequence number update.
If the object in b network management data storehouse has this configuration, but sequence number in sequence number and the network element of configuration item is inconsistent, the configuration in Update Table storehouse, and be the sequence number that network element transmits by sequence number update.
If the object in c network management data storehouse has a certain configuration, but does not comprise this configuration in the configuration of network element, webmaster deletes this configuration, and is the sequence number that network element transmits by sequence number update.
Configuration sequence number form by 4, from 0～15, webmaster and network element all adopt from 0～15 circulation mode.When the configuration of network element is to have while being imported by customized configuration, can not check directly synchronous all data, webmaster and network element should synchronously be initialized as 0 by sequence number.
Shown in Figure 4, the idiographic flow of the synchronous network element of webmaster is as follows:
Because the main control unit in network element is divided into master and standby dish, therefore the synchronous network element of webmaster will carry out in master and standby dish simultaneously.Webmaster issues synchronous process and webmaster, and to issue the process of configuration similar.Difference is for configuration is just for single object, and the synchronous network element of webmaster is that multiple configurations of multiple objects are packaged and issue respectively each network element.The configuration packet that subpackage-compressed package module of network element is sent webmaster is decomposed into order one by one, and resolves to the configuration of single network element.These configuration distributings are given each network element by webmaster, if network element runs succeeded, returns successfully and order to webmaster, and sequence number is added to 1 operation.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if these amendments of the present invention and within modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
