Provide better embodiment of the present invention according to Fig. 1-Fig. 7 below,, rather than be used for limiting the scope of the present invention so that explanation the present invention makes it to understand performance of the present invention, feature and structure better.
Come the inventive method is described in detail below by system construction drawing, system construction drawing as shown in Figure 7, it comprises foreground 61 and the backstage 60 that becomes double-way connection with circuit,
Wherein, backstage 60 comprises business configuration and interface 602 and webmaster part 601, and the major function at this business configuration and interface 602 is to realize the automatic selection of professional route, the professional configuration automatically and professional change, and user's configuration interface is provided.Webmaster part 601 is then mainly formed (not shown) by NM server, network element processing module and data server.The data that the business configuration module produces are by 601 times control sections 611 to network element of webmaster part, by network element control part 611 data are sent to again and intersect on control section 612 and the branch road control section 613, finish checking jointly business datum by intersecting control section 612 and branch road control section 613.Foreground partition 61 comprises network element control part 611, intersection control section 612 and branch road control section 613, the main function that realizes two parts: 1. set up interim service channel according to the data of business configuration module, determine the formal foundation of service channel again according to follow-up checking situation.2. finish the checking of the service channel that produces by business configuration.Network element control part 611 mainly is message and forwarding of data; The control section 612 that intersects is the processing to time slot-time slot data; Finish the foundation and the checking of time slot branch road on the branch road control section 613.
Business configuration module in business configuration part and the interface 602 is to produce professional required time slot to prop up circuit-switched data, mainly the problem of Xie Jueing: the selection of route, time slot take the change of business.In the present embodiment, webmaster part 601 is made of NM server, network element processing module and data server, routing program 20 and light mouth Time Slot Occupancy program 30 all are based upon on the network element processing module, professional configuration process program 40 automatically is based upon on the NM server, and data then are stored in the data server.
The number of services of network of the present invention is unit with the ring, all is that unit considers with the ring during in definite route with to time slot analysis.Simultaneously for convenience, during problem analysis if no special instructions network element to connect be object with the ring only all, under the situation of protection all the situation with two fine unidirectional multiplex sections be object.
Carrying out at first network element in the network and network topology being carried out preliminary treatment before route determines.Network element is positioned over different rings by the network topology situation constitutes the network element distribution table.Above-mentioned table 1, table 2 and table 3 are kept at the form of static data in the database of webmaster part 601 on backstage 60.For network topological diagram, because we are to be that unit handles route with the ring, thereby to be changed to topological diagram with the ring label be the adjacent map of unit, simultaneously the adjacency list of kymogram and the situation of joining, in the present embodiment, have 14 foregrounds 61, be set at respectively network element 1, network element 2 ... network element 13 and network element 14, and be positioned over respectively on ring A, ring B, ring C, ring D and the ring E that constitutes network topological diagram, as Fig. 1, Fig. 2, table 1 is shown in table 2 and the table 3.
Table 1 network element distribution table

(comprising network element number, the ring label).
Because network element all is to belong to ring, the Route Selection of network element just is converted into the route of at first determining ring like this, determines the route of network element according to protection and situation about not protecting again, handles so that carry out the time slot of back.By with the ring being the network adjacent map of unit, we can determine the route of ring by the rudimentary algorithm of figure--breadth-first search.Because under the situation of protection; processing to the network element time slot all is to be unit with the ring; therefore route only need determine that the route of encircling gets final product; under unshielded situation; need each network element on definite professional route; then determine the network element of professional route process successively by the ring that the obtains situation that to be unit connect according to network element (the connection data that network element is generally all arranged when the network configuration are in this specified otherwise not) with loop.
Among Fig. 1, present embodiment determines at first that to determine that network element 1 is an example to the route of network element 14 network element 1 belongs to ring A, and network element 14 belongs to ring E, not in same ring, determines that by breadth-first the route of ring is: A-B-E or A-D-E.Optional wherein one: A-B-E.Need note in following of the situation of protection and to encircle number, be that unit handles with the ring when time slot analysis.Under situation about not protecting; earlier according to the network element between the joining (network element 2) of definite network element 1 to A of network element connection and B; the network element that the joining network element of definite again network element 2 to B and E is 7 is determined the network element of network element 7 to 14 of network elements at last, thereby has determined the route of network element.
The handling procedure 20 of route resides on the webmaster part 601 on backstage 60, its flow process is as shown in Figure 3: behind the 200th step start-up routine, entered for the 201st step, determine the ring that source network element and purpose network element are affiliated, did the 202nd step judge whether it is same ring? if in same ring, carry out the 205th step record ring number, carried out for the 207th step again, EP (end of program).If not in same ring, otherwise carried out for the 203rd step, by the method for breadth-first search determine loop by, carried out for the 204th step again, does judging have unprotect? carried out for the 205th step if any protection, record ring number carried out for the 207th step again; EP (end of program); As unprotect, then carried out for the 206th step, determine concrete network element with the joining of encircling by the situation that the is connected segmentation of network element according to ring number and ring, the network element on the record traffic route is carried out the 207th then and is gone on foot EP (end of program).
After this, enter the time slot processing procedure:
The processing procedure of time slot is actually the processing to the record of the Time Slot Occupancy on the network element light mouth.Passed through network element 1,2,3 such as a business, the time slot on the so corresponding light mouth is occupied, and when other business was passed through these network elements, these occupied time slots just can not be used again.
For the situation of protection (because various protection types have different disposal; two fine unidirectional multiplex section protections only are discussed for convenience of explanation in the present embodiment); network element 1 not only then; 2; the time slot of relative photo mouth is occupied on 3, and the relative photo mouth time slot of other network elements on their the place ring also can be occupied.So, under the situation of protection we to the processing of route be the record loop by, when handling Time Slot Occupancy, be unit, and to unshielded situation with the ring, the network element that the record traffic route is passed through.
We are that unit is that the time slot of its each light mouth is done one and taken record with the network element, when business is passed through this network element, then inquire about from taking the record of network element, see whether the corresponding light mouth of this network element has available time slot or available time slot whether to satisfy the requirement of number of services, if do not have or do not meet the demands then business can not be passed through this network element, need look for a route in addition, if there is no other route then can not be configured.
The situation that takies of time slot is handled, present embodiment is handled by following two kinds of situations, promptly the network element of Chu Liing is to liking the network element of being determined by Route Selection: 1. route data is a loop data: be that unit handles respectively with the ring, obtain ring and go up the relative photo mouth Time Slot Occupancy record of all network elements, check whether the available time slot of each network element satisfies the requirement of number of services, can be with number of timeslots more than or equal to number of services, meet the demands then according to number of services upgrade each network element relative photo mouth time slot take record, not satisfying then selects other route to handle, as there not being other route, then can not be configured.2. route data is a network element data: the relative photo mouth Time Slot Occupancy record that obtains all network elements, check whether the available time slot of each network element satisfies the requirement of number of services, can be with number of timeslots more than or equal to number of services, meet the demands then according to number of services upgrade each network element relative photo mouth time slot take record, not satisfying then selects other route to handle, as there not being other route, then can not be configured.Time Slot Occupancy handling procedure 30 resides on the webmaster part 601 on backstage 60, its flow process as shown in Figure 4:
From the 300th step program start, afterwards, carried out for the 301st step, do you judge that route is made of ring? if, entered for the 302nd step, obtain all network elements on each ring successively, carried out for the 303rd step again, if not, then directly carried out for the 303rd step, the Time Slot Occupancy record of inquiry related network elements afterwards, carried out for the 304th step, judge whether to satisfy service needed? if, carried out for the 305th step, upgrade the Time Slot Occupancy record, afterwards, carried out for the 307th step, EP (end of program); Otherwise, carried out for the 306th step, is judgement that other routes are arranged? if have, then return and carried out for the 301st step; If do not have, then carried out for the 307th step, EP (end of program).
After handling the Time Slot Occupancy of network element, the required time slot of just can managing business props up circuit-switched data and time slot-time slot data.Time slot prop up circuit-switched data be for determine business specifically be by on that branch road to that channel time slot, just produce at source network element and purpose network element place, the analysis situation and the time slot analysis of branch road are similar: each network element has branch road to take record, at first take available the way that branch road checked in record according to branch road, meet the demands (available way is greater than professional number) then be configured and upgrade the record that takies of branch road, do not satisfy then can not be configured.Time slot-time slot data are to produce at the joining place, set up the data that are connected of time slot and time slot on the light mouth of correspondence.
By above analytical procedure, produce the data of the required automatic configuration of business, by webmaster part 601 relevant data are saved in the database, as must checking then carrying out proof procedure, do not verify and then preserve professional relevant time slot-time slot data, the time slot branch road that time slot props up circuit-switched data and network element takies data, and will set up professional required time slot-time slot data and prop up circuit-switched data with time slot and send to relevant network element.The checking of configuration:
In order to guarantee the reliability of configuration automatically, this method provides the authentication function of business configuration, and the data that produced by automatic configuration section are verified.Checking is by foreground 61 (network element control part 611, intersection control section 612, branch road control section 613 and backstage 60 (webmaster part 601) cooperate finishes, by webmaster part 601 data that business configuration produces are dealt into network element control part 611, control intersection 612 and branch road control section 613 are finished professional checking, and the result fed back to webmaster part 601, background interface will verify that the result feeds back to the user.
In the structure of system shown in Figure 7, business configuration and interface 602 belong to the configuration that webmaster part 601 is finished business datum, and network element control part 611 and intersection control section 612, branch road control section 613 are finished the business checking of network element.
The processing procedure of checking:
Verify message and the related data that produces by automatic configuration by webmaster part 601 to relevant network element transmission.Network element control part 611 sends checking message and occasional service data according to the occasional service data (time slot-time slot data and time slot prop up circuit-switched data) that obtain from webmaster part 601 to intersection, branch road control section 612,613.Intersecting control section 612 and branch road control section 613 builds the occasional service passage according to the occasional service data, finishes checking to data by branch road control section 613.At last, the result of checking returns to webmaster part 601 by network element control part 611.
The handling procedure 40 of whole automatic configuration section resides on the webmaster part 601 on backstage 60, its flow process as shown in Figure 6:
From the 400th step start-up routine, afterwards, carried out for the 401st step, in type of service, quantity and the protection type determined on 60 interfaces, backstage between source network element and purpose network element and the network element, carried out for the 402nd step, in backstage business configuration part professional route and time slot being propped up circuit-switched data handles, produce professional required data, carried out for the 403rd step, judge whether checking? if not, jump and carried out for the 409th step, the webmaster part writes 611 times databases of database and the network element control unit in foreground 61 with data, carried out for the 4010th step again, EP (end of program); If, then carried out for the 404th step, by webmaster part 601 data of business configuration are dealt into network element control part 611 in the foreground 61, carried out for 405 steps again, network element control part 611 in the foreground 60 mails to intersection control section 612 and branch road control section 613 with data, afterwards, carried out for the 406th step, verify by the branch road control section 613 in the foreground 61, and the result is beamed back the webmaster part 601 on backstage 60, the cancellation occasional service carried out for the 407th step again, webmaster part 601 from the background interface to the user feedback authorization information, afterwards, carried out for the 408th step, judge whether to accept data? if not, directly entered for the 4010th step; If, then carried out for the 409th step, the webmaster part 601 in the backstage 60 writes database with data, and to the 611 times databases in network element control unit, carries out for the 4010th step again, EP (end of program).Summarize the automatic configuration process program of business of the present invention, promptly obtain relevant data by webmaster part 601 earlier, partly produce professional required data by business configuration, need not verify then data are saved in the network management data storehouse, and business datum is sent to relevant network element; Need checking then to send checking message and business datum to relevant network element by webmaster part 601, finish checking by network element to automatic configuration data, and the result turned back to background interface, whether accept data by user's decision at last, accept then data to be saved in webmaster part 601 databases, and will arrive related network elements under the business datum.
Building and professional checking of foreground 61 main realization occasional services in the present embodiment, network element control part 611 obtains occasional service data (time slot-time slot data and time slot prop up circuit-switched data) from webmaster part 601, to intersecting control section 612 and branch road control section 613 transmission checking message and occasional service data.Intersecting control section 12 and branch road control section builds the occasional service passage according to the occasional service data, finishes checking to data by branch road control section 613, after sending the checking results to webmaster part 601, cancels the occasional service passage.
Foreground handling procedure 50 is based upon on the network element control part 611, and its flow process is as follows:
Behind the 500th step start-up routine, entered for the 501st step, network element control part 611 obtains the occasional service data from webmaster part 601, carries out for the 502nd step afterwards, judged whether time slot-time slot data? if do not have, carried out for the 504th step just stride; If have, then carried out for the 503rd step, time slot-time slot data are sent to intersection control section 612, carried out for the 504th step again, time slot-time slot data are sent to branch road control section 613, afterwards, carried out for the 505th step successively, set up the occasional service passage, carried out for the 506th step, by branch road control section 613 checking passages, carried out for the 507th step, the webmaster part 601 to backstage 60 sends feedback information, carried out for the 508th step, cancel the occasional service data, last, carried out for the 509th step, EP (end of program).
The method system of the checking of being adopted in the present embodiment utilizes lower order path overhead J2 byte to handle, and in G.707, the J2 byte is used as the low order channel trace byte.The process of handling: the corresponding passage at the source network element when beginning to verify carries out write operation to the J2 byte, write specific content, respective channel at the purpose network element reads the J2 byte, and with the expectation numerical value compare, unanimity then passage can be used, automatically the data that produce of configuration are correct, otherwise then data are incorrect or passage is unavailable.
Because the process of checking adopts the process of batch processing, promptly once be that unit handles a plurality of service channels with the network element, after all occasional service passages that produced by automatic configuration data all are verified on this network element, the result is turned back to webmaster part 601 simultaneously, the user can be according to the feedback data situation, and part or all of data are wherein accepted in decision.
Adopted professional automatic configuration method, the user no longer needs the concrete configuration of service channel is considered, only needs to determine professional value volume and range of product, thereby has reduced the complexity of working; The user can also carry out batch process to business, thereby no longer carries out repeated operation when a plurality of business are handled, and has reduced user's workload; The checking of business datum has guaranteed the credibility of work especially.In a word, the inventive method has very strong practicality and reliability.
