Description
Technical field
The present invention relates to intelligent net element administrative skill in a kind of ASON, particularly realize synchronous method and the network management system of intelligent net element intersection information.
Background technology
Network element in the ASON, comparing common network element is conventional synchronous digital series (SDH) transmission equipment, its maximum characteristics are, network element has intelligent characteristic, that is: network element device can be initiated to create professional application, real-time monitoring business state, also can be carried out heavy-route or the like according to the service condition variation.At present; ASON is realized function such as business configuration end to end at key-course; and business configuration is converted to intersection information, and to be handed down to legacy hosts be SDH transmission equipment, the service channel with protective feature and bandwidth (LSP) that is become to be communicated with by the interconnection of each network element.Here, interconnection is to be used for signal forwarding, multiplexing, the least unit of divide inserting in the SDH transmission equipment, and described intersection information is the information that is used for describing SDH equipment interconnection situation.
Wherein, for intelligent net element, its smart host software is positioned at the key-course of network, and realizes following function: calculate professional end to end route automatically according to requirements such as sourcesink, bandwidth, protection types; Go out required intersection information according to property calculation such as the rank of business, route, protection types; Intersection information is converted to cross-over configuration orders such as establishment, deletion, and is handed down to legacy hosts; Obtain the state of whole piece business according to all cross-coupled modes of operation in the legacy hosts; Take place or during upgrading service, obtain new intersection information in fault, and new intersection information is converted to the cross-over configuration order is handed down to legacy hosts thereby calculate new routing iinformation automatically.
That is to say, smart host in the intelligent net element can calculate intersection information automatically according to current business configuration, and intersection information is converted into the cross-over configuration order is handed down to legacy hosts, legacy hosts is reshuffled the interconnection of self according to the cross-over configuration information in the cross-over configuration order, adds, deletes interconnection etc. that is:.
Fig. 1 is the network management system frame construction drawing of existing ASON, as shown in Figure 1, existing network management system mainly comprises: network element message processing module, query processing module, checking warehousing module, MIT information bank, foreground interactive module and foreground, intelligent net element comprises: smart host and legacy hosts.
Wherein, the network element message processing module is connected with legacy hosts, be responsible for to transmit the message between webmaster side and the network element side, and the information that receives is carried out conversion between discernible form of webmaster side and the discernible Host Command word format of network element; Query processing module links to each other respectively with network element message processing module, checking warehousing module, foreground interactive module; The foreground interactive module is connected with the foreground, and checking warehousing module is connected with management information tree (MIT) information bank.
The network maintenance staff inquires about the intersection information of intelligent net element, and the intersection information that inquiry obtains is saved in the MIT information bank by foreground input inquiry request, and main processing procedure is as follows:
At first, the foreground is sent to query processing module with query requests by the foreground interactive module, and this query requests is indicated the identifier (ID) of network element to be checked.Query processing module can judge that according to this query requests this request requires this network element intersection information that preserve or this network element self preservation in the inquiry MIT information bank.Then, transmit this query requests to verifying warehousing module/network element message processing module according to the judged result query processing module, this network element message processing module changes into the discernible Host Command word of legacy hosts with this query requests, and this query requests is sent to the legacy hosts of this network element according to the ID of network element to be checked in the query requests; Perhaps, by checking warehousing module this query requests is forwarded to the MIT information bank.
Then, this legacy hosts is according to the query requests of the Host Command word format that receives, the intersection information that self is current returns to the network element message processing module as Query Result, and this network element message processing module changes into this Query Result the discernible data format of webmaster side and is sent to query processing module; Perhaps, the MIT information bank is sent to checking warehousing module with this network element intersection information of self preserving as Query Result according to this NE ID in the query requests, after checking warehousing module is proved to be successful intersection information this Query Result is sent to query processing module.
At last, if query processing module receives Query Result from the network element message processing module, then this Query Result is sent to checking warehousing module, after being proved to be successful, this intersection information will be verified the warehousing module and be sent to the MIT information bank and preserve, and by query processing module Query Result is sent to the foreground by the foreground interactive module simultaneously, be shown to the network maintenance staff; If query processing module receives Query Result from checking warehousing module, then this Query Result is sent to the foreground by the foreground interactive module, be shown to the network maintenance staff.
Wherein, the checking that checking warehousing module is carried out intersection information is mainly: whether the judgment data form correct or the like, with guarantee transfer of data accurately.
According to above description as seen, in the existing intersection information administrative mechanism, the webmaster side can be preserved the intersection information of each network element, the intersection information of preserving with the webmaster side that can inquire about also that each network element self preserves.But when legacy hosts was reshuffled its interconnection, the cross-coupled change that is produced did not report the webmaster side, and at the main feature of ASON, the intersection information that this kind mechanism will make network element side and webmaster side be preserved is difficult to synchronously.
Because, network element does not report the relevant change that intersects to the webmaster side, cause the actual conditions of each network element intersection information that the webmaster side preserves and each network element inconsistent, therefore, the webmaster side can't be monitored in real time and manage the intelligent intersection information change of generations such as the change of LSP, heavy-route, fault recovery.Like this, obtain the intersection information of network element reality if desired, then must arrive in the concrete network element and inquire about, promptly present ASON can only be realized static management for the intersection information of network element.
Therefore, existing network management system can not be carried out the management of automation to the network element intersection information, the webmaster side is not understood the true operating position of present system resource, when network management system is operated according to the intersection information of self preserving, just be easy to occur the operation of resource contention, bring inconvenience to the user, also be easy to generate some unpredictable consequences.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Main design philosophy of the present invention is, when change took place the intersection information of intelligent net element, intelligent net element initiatively reported to the webmaster side and intersects change message, and the webmaster lateral root intersects the intersection information of this network element in the change information updating MIT information bank in view of the above.In order to realize the real-time report of intelligent net element intersection information change, the invention provides a kind of by the synchronous network management system of intelligence intersection synchronization module realization intelligent net element intersection information.
Fig. 2 is the frame structure of network management system one preferred embodiment of the present invention, and as shown in Figure 2, this system comprises: the MIT information bank, and this system also comprises: intelligence intersection synchronization module, it comprises: lock unit and checking mould are determined; Wherein, lock unit receives intersection change information and sending to authentication module from intelligent net element; Authentication module, receive intersection change message from lock unit, extract this network element intersection information according to this intersection change message from the MIT information bank and verify, and select directly to send updating message and after this network element extracts its whole intersection information, send updating message to the MIT information bank to the MIT information bank or by lock unit according to whether being proved to be successful.Described MIT information bank is used for according to updating message the intelligent net element intersection information of self preserving being upgraded.Here, if the network element intersection information that intelligence intersection synchronization module is not preserved the webmaster side when receiving intersection change message is verified, then intelligence intersection synchronization module can only comprise synchronization module, and it is used for receiving intersection change information and sending updating message to the MIT information bank from intelligent net element.Described lock unit can be realized by the network element message processing module of existing network management system.
In the said system, when the authentication module authentication failed, inquire about the network element intersection information by lock unit automatically, system of the present invention can also be when authentication failed be said the word by the foreground and triggers authentication module inquiry network element intersection information, further comprise in the system then shown in Figure 2: the foreground, it is used to receive the synch command of user's input and export synchronization request to authentication module; Described authentication module further sends synchronization failure message to the foreground, and receives the synchronization request on foreground.
Based on network management system shown in Figure 2, the present invention realizes the synchronous processing of intersection information as shown in Figure 3, and Fig. 3 is applied to the handling process schematic diagram of network management system shown in Figure 2 for the inventive method, and it comprises following treatment step:
Step 301: the smart host of intelligent net element receives the business configuration order.Here, described business configuration order can be for initiating business, change orders such as business configuration or winding-up, and the business configuration order can be initiated by User Network Interface (UNI) by the user, also can be issued by the webmaster side.
Step 302: smart host calculates intersection information according to the business configuration order that receives, and this intersection information is changed into the legacy hosts that the cross-over configuration order is handed down to this network element.
Here, comprise the new cross-over configuration information that is produced by current business configuration in the described cross-over configuration order, configuration informations such as intersecting, revise intersection can be intersected, be deleted to this cross-over configuration information for creating according to the difference of current business configuration; Described cross-over configuration order also can initiatively issue because of former reason smart hosts such as " heavy-routes ", and need not that order produces according to business configuration.
Step 303: legacy hosts is reshuffled the intersection information of self according to the cross-over configuration information in the described cross-over configuration order of step 302, can add new interconnection at self according to creating the configuration information that intersects such as: legacy hosts, perhaps the configuration information that intersects according to deletion is with self existing interconnection deletion or the like.
Step 304: the lock unit in the extremely intelligent intersection synchronization module of legacy hosts transmission intersection change message of network element.
When legacy hosts the intersection information of self being reshuffled is that intelligent net element is when change has taken place to intersect, legacy hosts in the intelligent net element will intersect the change message be sent to lock unit, lock unit sends updating message to the MIT information bank again according to intersection change message, and the MIT information bank can upgrade this network element intersection information of self preserving according to this updating message then.Here, described lock unit can be by the network element message processing modules implement in the existing network management system.
Here, described intersection change message comprises: NE ID, alter mode, and the intersection information of change etc., described updating message comprises the NE ID in the intersection change message at least, alter mode, and the intersection information of change, then the MIT information bank can be according to the NE ID in the updating message, the intersection information of alter mode and change is upgraded, such as: alter mode is for creating, the new intersection information of then corresponding increase, alter mode is deletion, the existing intersection information of then corresponding deletion etc., thereby make network element when its intersection information of change, the MIT information bank of webmaster side also can be tackled this network element intersection information of its preservation mutually and be upgraded.
Because, network element and webmaster side can break contact in some cases, if the change of network element intersection information has taken place during this period, network element just can't will intersect the intelligence intersection synchronization module of change information reporting to the webmaster side, therefore, the network element intersection information of webmaster side preservation and the situation that actual intersection information is not inconsistent still can appear.In view of this, the inventive method can also increase according to intersecting the process that message is verified the network element intersection information of webmaster side preservation that changes in the webmaster side, then network element sends intersection change message to lock unit in step 304, further comprises following processing:
Step 305: the intersection change message that the lock unit buffer memory receives, should intersect the change forwards to authentication module, verify in the intersection information of webmaster side that by authentication module and to this network element this proof procedure can be verified or verification of correctness or the two combination for timestamp.
Described timestamp checking is specially: each network element has all been stored a timestamp in advance, and the webmaster side has also been preserved a timestamp for each network element, and timestamp can be 0 to the OxFFFO counter that constantly circulates and add up; When change takes place in the each intersection information of network element, timestamp just adds 1 and report to the webmaster side, the webmaster side is whenever received the timestamp of this reported by network elements, meeting adds 1 with the timestamp of this network element that self stores, like this, if this network element timestamp of preserving with the webmaster side that network element is preserved is inconsistent, illustrate then that this network element and webmaster side once-interrupted are crossed to get in touch, and during network element the intersection information change has taken place, just illustrate that also the intersection information of network element and webmaster side may occur inconsistent.
Here, if carry out the timestamp checking, when then change takes place to intersect in network element at every turn, also the timestamp of self current preservation is reported authentication module by lock unit simultaneously, this authentication module reads the timestamp that the webmaster side is preserved for this network element by this NE ID in the intersection change message from the MIT information bank, and this timestamp is added 1 obtain current webmaster side timestamp, then, authentication module compares the timestamp and the current webmaster side timestamp of this reported by network elements, if two timestamp unanimities then are proved to be successful; Otherwise network element intersection information synchronization failure has promptly taken place in authentication failed.
Described verification of correctness is specially: network element will intersect change message when being sent to authentication module at every turn, this authentication module reads the intersection information of this network element by intersecting NE ID in the change message from the MIT information bank, the intersection information contradiction whether that intersecting of judging that intersection information that the webmaster side preserves and network element send changed alter mode in the message and change.Such as: what network element was sent is to create the intersection change message of intersecting, but there has been this intersection information in this network element intersection information that the webmaster side is preserved, what perhaps network element was sent is the intersection change message that deletion intersects, and this intersection information not in this network element intersection information that the webmaster side is preserved, intersecting of illustrating then that intersection information that the webmaster side preserves and network element send changes message contradiction taken place.Like this, if described verification of correctness result is a contradiction, then network element intersection information synchronization failure has promptly taken place in authentication failed; Otherwise be proved to be successful.
Step 306: authentication module judges whether checking is successful, if success, execution in step 308; Otherwise execution in step 307.
Here, describedly be verified as the checking of carrying out in the step 305, can verify for timestamp, also can be verification of correctness, perhaps for the two combination,, then have only and all successfully could adjudicate this when the checking of this correctness and timestamp and be proved to be successful if be the checking of the two combination.
Step 307: authentication module sends query requests by lock unit and to this network element of synchronization failure takes place, and this network element returns the Query Result that comprises self whole intersection information by lock unit and gives authentication module.Here, comprise this NE ID in this query requests at least, authentication module sends query requests to this network element by this NE ID.
Step 308: authentication module sends updating message to the MIT information bank.
Wherein, when step 306 is proved to be successful this step of back execution, authentication module sends updating message according to the intersection change message that receives, then intersect and change message transmission updating message, comprise at least in the described updating message: the intersection information of NE ID, alter mode and change in the described intersection change message according to this; When after the intersection information of step 307 inquiry synchronization failure network element, carrying out this step, authentication module sends updating message according to the Query Result that receives, then send updating message, comprise at least in the described updating message: the whole intersection information of this network element in this NE ID and the described Query Result according to this Query Result.
In addition, if carried out the timestamp checking in step 305, then the also further transmitting time of authentication module is stabbed updating message in this step, and this message comprises at least: the timestamp of this NE ID and this reported by network elements.
The step 309:MIT information bank intersection information of 308 described updating message this network element that self is preserved set by step upgrades.
Be exactly specifically, when step 306 is proved to be successful this step of back execution, the MIT information bank is according to the intersection information of the NE ID in the updating message, alter mode and change, creates new intersection, deletion or revises existing intersection information etc. on this network element intersection information basis of self current preservation; When after the intersection information of step 307 inquiry synchronization failure network element, carrying out this step, the MIT information bank is according to NE ID in the updating message and the whole intersection information of this network element that obtain of inquiry, and this network element intersection information with self current preservation all replaces with the intersection information that inquiry obtains again.In addition, if authentication module has sent update of time stamp message in step 308, then the MIT information bank also will be according to this timestamp updating message with the corresponding timestamp of self preserving that replaces to this reported by network elements in the update of time stamp message of this network element timestamp in this step.
In the above-mentioned processing procedure, when the intersection information of intelligent net element and the preservation of webmaster side is asynchronous, authentication module will be inquired about the intersection information of the asynchronous network element of this generation intersection information automatically, use this kind Automatic Analyzer system to be suitable for the network management system that network size is less, intelligent net element quantity is few of being managed.
When the phenomenon of intersection information synchronization failure of self intersection information and webmaster side has appearred in a large amount of network elements, upgrade and handle if carry out the inquiry of a large amount of network elements and intersection information simultaneously, system just might can't work owing to inadequate resource.Therefore, when the present invention is applied in the NE quantity system with more, when the intersection information of network element intersection information and webmaster side is asynchronous, for foreground queries mechanism is adopted in the safe operation that guarantees system, report synchronization failure message by authentication module to the foreground, select when the intersection information of this network element to be inquired about and upgrade according to the general status of current network intersection information synchronization failure by the user again, thus foreground intersection information by authentication module and lock unit inquiry network element when receiving the synch command that the user sends.
When adopting this kind working method, above-mentioned steps 307 is: authentication module reports synchronization failure message to the foreground, the foreground sends synchronization request to authentication module after obtaining synch command, the intersection information of this network element is inquired about by lock unit by authentication module, and extract Query Result by lock unit.
Fig. 4 is another preferred embodiment frame structure schematic diagram of network management system of the present invention.Among Fig. 4, described lock unit is by the network element message processing modules implement in the existing network management system; Described authentication module is realized by query processing module in the existing network management system and checking warehousing module; Wherein, the network element message processing module is used to receive the intersection change information and sending of intelligent net element to verifying the warehousing module, query requests between forwarding inquiries processing module and the intelligent net element and the Query Result that comprises the whole intersection information of this network element; Query processing module is used to transmit query requests and Query Result between checking warehousing module and the network element message processing module; Checking warehousing module is used for verifying from the intersection information that the MIT information bank extracts this network element according to the intersection change message from the network element message processing module, directly sends updating message to the MIT information bank according to the checking result again; Perhaps, send query requests, send updating message to the MIT information bank according to this network element Query Result that receives to query processing module.
Here, described authentication module extracts the processing of intelligent net element intersection information, can be as mentioned above by himself automatic triggering, also can trigger by the synchronization request that the foreground sends, when the synchronization request that is sent by the foreground triggers authentication module extraction intelligent net element intersection information, system shown in Figure 4 further comprises: the foreground is used to receive synch command and exports synchronization request; Described authentication module further comprises: the foreground interactive module.
At this moment, the function of the network element message processing module in the system is constant, and the function of other module changes to some extent.Wherein, query processing module is used for receiving synchronization request and sending query requests to the network element message processing module from the foreground interactive module, receives from the Query Result of network element message processing module and is forwarded to checking warehousing module; Checking warehousing module is used for verifying from the intersection information that the MIT information bank extracts this network element according to the intersection change message from the network element message processing module; Directly send updating message to the MIT information bank according to the checking result again; Perhaps, send synchronization failure message, receive from the Query Result of this network element of query processing module and send updating message to the MIT information bank to the foreground interactive module; The foreground interactive module is used to receive from the synchronization failure message of checking warehousing module and is forwarded to the foreground, receives from the synchronization request on foreground and is forwarded to query processing module.
Here, more friendly for the user interface that makes network management system, described query processing module can also further be returned Query Result to the foreground by the foreground interactive module after obtaining Query Result, and the network element intersection information that inquiry is obtained is shown to the user.
Preferred embodiment frame structure based on the described network management system of the present invention of Fig. 4 is described in detail the inventive method below in conjunction with accompanying drawing.
Fig. 5 is applied to the handling process schematic diagram of network management system shown in Figure 4 for the inventive method, and as shown in Figure 5, concrete treatment step is as follows:
Step 501: the legacy hosts of intelligent net element sends the intersection Notification of Changes and synchronous sequence number is notified to the network element message processing module.
Here, described intersection Notification of Changes is the described intersection change of Fig. 3 message, described synchronous sequence number notice is the timestamp of the described reported by network elements of Fig. 3, described intersection Notification of Changes comprises the intersection information of NE ID, alter mode and change at least, and described synchronous sequence number notice comprises the timestamp of self preserving of this reported by network elements at least.
Step 502: the network element message processing module is forwarded to checking warehousing module with described intersection Notification of Changes of step 501 and synchronous sequence number notice.
In the present embodiment, system carries out timestamp and verification of correctness to the intersection information of network element, so network element reports the synchronous sequence number notice and the Notification of Changes that intersects simultaneously; System also can only carry out verification of correctness, and then network element needn't report synchronous sequence number notice here.
Step 503: verify synchronous sequence number notice and intersection Notification of Changes that warehousing module buffer memory receives, and the intersection information of this network element is verified, and whether the judgement checking is successful, if execution in step 504 according to this synchronous sequence number notice and the Notification of Changes that intersects; Otherwise promptly synchronization failure has taken place in this network element intersection information, execution in step 506.
Wherein, described timestamp checking and the verification of correctness of being verified as.Checking warehousing module can be extracted the intersection information and the timestamp of this network element by this NE ID in the intersection Notification of Changes from the MIT information bank, and according to the timestamp in the synchronous sequence number notice, intersect alter mode in the Notification of Changes and the intersection information of change and the correctness and the timestamp of this network element intersection information verified by the verification method described in Fig. 3, and have only correctness and timestamp checking all success could adjudicate this and be proved to be successful.
Here, checking warehousing module also can only be carried out the timestamp checking or only carry out verification of correctness the intersection information of network element by the described method of Fig. 3.
