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 administrative unit of mentioning among the present invention and can be to realize the manager of any network management task and by manager by pipe unit.For example, they can be respectively business operation support system (BOSS) and network management unit (NMS) or NMS and NE management unit (EMS) or EMS and the network elements (NE) etc. in the OSS.And the Network Management Function of being mentioned among the present invention comprises webmaster service function and entrance function.And as described in the background section, administrative unit and all are logic entities by pipe unit, they can be any system or device in the reality, though be referred to as " administrative unit " or " by pipe unit " herein, also can be called " management system " or " by guard system " etc.
The present invention makes the server end that is comprised this entrance, upgrading back function in the pipe unit to being carried out the upgrading of functional class by the entrance function in the pipe unit; And, make to be comprised preceding webmaster service function server end of upgrading and upgrading back webmaster service function server end in the pipe unit simultaneously to being carried out the upgrading of system level by the webmaster service function in the pipe unit; Administrative unit before the upgrading is by being inquired about the webmaster service function information that this is provided by pipe unit by the server end of entrance function after the upgrading in the pipe unit, and, realize network management by being used the webmaster service that is provided by pipe unit by webmaster service function server end before the upgrading in the pipe unit.
Above-mentioned step of the entrance function being carried out the upgrading of functional class can comprise: to being upgraded by the entrance function in the pipe unit, and make entrance function before entrance function after the upgrading is inherited upgrading.In addition, the present invention also proposes the specific implementation method to the entrance function upgrading, comprising extended operation, the specific implementation etc. that increases operation, expansion notice and increase notice.
The above-mentioned step that the webmaster service function is carried out the upgrading of system level comprises: the interface that generates upgrading back webmaster service function is described, and describes the server end that generates upgrading back webmaster service function according to this interface; The server end that in by pipe unit, keeps original webmaster service function, and in this original webmaster service function server end running, in by pipe unit, install and move the server end of described upgrading back webmaster service function.
Describe network management method below in detail according to backward compatibility network management system of the present invention.For the purpose of narrating conveniently, suppose that at first the version by the entrance function in the pipe unit when the backward compatibility network management system is a, and the version of webmaster service function is b.Wherein, realized the server end of this a version entrance function and b version webmaster service function by pipe unit, provide the query function of this b version webmaster service function information by this a version entrance function for administrative unit, and provide this b version webmaster service function to administrative unit.Administrative unit then realizes the client of this a version entrance function and b version webmaster service function, by a version entrance functional inquiry that provided by pipe unit by the b webmaster service function information of pipe unit, and use corresponding b version webmaster service function, thereby carry out network management.And suppose by the version of entrance function after the upgrading of pipe unit to be c, the version of upgrading back webmaster service function is d.The method flow of present embodiment specifically comprises the steps: as shown in Figure 1
Step 101: the interface that generates c version entrance function is described the interface description of (Interface Description) and d version webmaster service function, make the interface of this c version entrance function describe the interface description of inheriting a version entrance function, and the server end of realizing c version entrance function is described according to the interface of c version entrance function, the server end of realizing d version webmaster service function is described according to the interface of d version webmaster service function.
Wherein, the concrete mode that the interface of the above-mentioned c of making version entrance function is described the interface description of inheriting a version entrance function can be succession, the succession of attribute, the succession of notice and the succession of dtd etc. of operation, wherein Cao Zuo succession specifically can be, for example: after upgrading, not only comprise original operation in all operations of version entrance function and can also comprise the operation that increases newly, perhaps the original a certain operation of upgrading back version entrance function can not only be handled the parameter of original operation, can also handle succession from the new argument of origin operation parameter etc.; The notice that version entrance, upgrading back function is supported not only comprises original notice, can also comprise the notice that increases newly, and perhaps original notice of version entrance, upgrading back function can also increase some notifying parameters newly.When specific implementation, both can take above-mentioned a kind of succession mode, also can take the combination in any of above-mentioned several succession modes.It should be noted that, to based on Common Object Request Broker Architecture (Common Object Request Broker Architecture, CORBA) network management system, can realize succession in this step according to the defined IDL of CORBA standard, and to the network management system based on Simple Object Access Protocol (SOAP), can be 200510091286.X according to the applicant's number of patent application then, the application name be called the mode of mentioning in " implementation method of information service level inheritance in the network interface " and realizes the succession described in this step.
Step 102: the server end with c version entrance function is replaced by the server end of a version entrance function in the pipe unit; In by pipe unit, keep original b version webmaster service function server end, and in this b version webmaster service function server end running, install and move the server end of above-mentioned d version webmaster service function in by pipe unit at this.
In this step, in the server end that adopts c version entrance function is replaced by pipe unit during the function server end of original a version entrance, can cause by the interruption of function service in entrance in the pipe unit, but, therefore can not cause by the interruption of network management services in the pipe unit because the entrance function does not directly provide network management services.In addition, because the installation of the server end of upgrading back version webmaster service function is to carry out in by the running of the original version webmaster service function assembly in the pipe unit, the outage that therefore can not cause this network management unit, also just can not influence the carrying out of corresponding network management function, thereby guarantee to carry out the continuity of network management task.
Step 103: the handle of the server end of use c version entrance function is restarted the client of original a version entrance function in the administrative unit, administrative unit is used the webmaster service function information searching function that is provided by the server end of c version entrance function in the pipe unit by the client of its a version entrance function, promptly by the information of webmaster service function is provided by pipe unit by the inquiry of the server end of c version entrance function in the pipe unit, and the client by its b version webmaster service function is provided by the webmaster service function that is provided by the server end of b version webmaster service function in the pipe unit, promptly, realize network management by being used the webmaster service that is provided by pipe unit by the server end of the b version webmaster service function in the pipe unit.
Wherein, because as described in above step 101, the server end of c version entrance function is to describe according to the interface of c version entrance function to realize, and the interface of this c version entrance function is described the interface inherited former a version entrance function and is described, thereby makes administrative unit can continue to use the service of a version entrance funtion part in this c version entrance function that is provided by pipe unit by the client of its a version entrance function.When the function of administrative unit need use that this is provided by pipe unit c version entrance, need to use the handle of this c version entrance function server end to restart the client of original version entrance function in the administrative unit.
Network management system for backward compatibility, just to being upgraded by pipe unit, and administrative unit is not upgraded, so administrative unit is merely able to client by its a version entrance function from the information of the b version webmaster service function that is provided by pipe unit is provided by the c version entrance function server end the pipe unit.Simultaneously, administrative unit also can only be used the original b version webmaster service function that is provided in the pipe unit by the client of its b version webmaster service function.Certainly, if the corresponding network management function in the administrative unit, also be upgraded to c version and d version respectively after including stomion function and webmaster service function assembly, then the c version entrance function client that just can pass through of administrative unit is used by the c version entrance function server end in the pipe unit and is inquired about this by webmaster service function information that pipe unit provided, use the webmaster service that is provided by the d version webmaster service function server end in the pipe unit by d version webmaster service function client, thus supervising the network.
Like this, owing to only the entrance function is taked the upgrade method of functional class, make that the administrative unit before the upgrading can be used the information of being brought in webmaster service function before the corresponding upgrading that inquiry provided by pipe unit by the entrance function server after the upgrading in the pipe unit by the entrance function client of its original version.And owing to only the entrance function is taked the backward compatibility of functional class, and the webmaster service function is taked the backward compatibility of system level, therefore with respect to the backward compatibility scheme of taking functional class in the prior art at the all-network management function, the present invention program does not need to consider the restriction of existing interface in escalation process, directly therefore the definition new interface implements than being easier to.Especially, to during by the upgrading of the corresponding webmaster service function of pipe unit and even during the webmaster service function upgrading to administrative unit afterwards, owing to need not to interrupt the operation of their original separately webmaster service functions, thereby can guarantee the continuity of webmaster service operation.
Be the network management method of example explanation backward compatibility network management system below with the CORBA system.In this embodiment, shown in Fig. 2 a, suppose that the preceding entrance of upgrading function is EPIRP, this EPIRP comprises: interface interface EPIRP, notice EPIRPNotification and dtd EPIRPDefs.Entrance, upgrading back function is EPIRP2, and this EPIRP2 comprises: interface interface EPIRP2, notice EPIRPNotification2 and dtd EPIRPDefs2.
Shown in Fig. 2 b, the webmaster service function is BasicCMIRP before the upgrading, and this BasicCMIRP comprises interface interface BasicCMIRP, notice BasicCMIRPNotification and network resources model NRM.Upgrading back webmaster service function is BasicCMIRP2, and this BasicCMIRP2 comprises interface interface BasicCMIRP2, notice BasicCMIRPNotification2 and network resources model NRM2.This BasicCMIRP2 is independent of BasicCMIRP, and also promptly: interface BasicCMIRP2 is independent of interface BasicCMIRP, and BasicCMIRPNotification2 is independent of BasicCMIRPNotification, and NRM2 is independent of NRM.Therefore, the content of interfaceBasicCMIRP2, for example operation can be different fully with the content of interface BasicCMIRP.The content of interfaceBasicCMIRP2 can obtain by adopting the mode that the content of interface BasicCMIRP is revised arbitrarily, expanded or deletes.The content of BasicCMIRPNotification2 also can be different fully with the content of BasicCMIRPNotification.And the content of BasicCMIRPNotification2 also can obtain by adopting the mode that the content of BasicCMIRPNotification is revised arbitrarily, expanded or deletes.
The following describes the flow process of present embodiment method, specifically comprise the steps:
Step 201: realize the server end of upgrading back entrance function EPIRP2, make EPIRP2 inherit EPIRP, and realize the server end of upgrading back webmaster service function BasicCMIRP2.
Wherein, shown in Fig. 2 a, the interface interface EPIRP2 of entrance function EPIRP2 inherits interface interface EPIRP, and notice EPIRPNotification2 inherits notice EPIRPNotification, and dtd EPIRPDefs2 inherits dtd EPIRPDefs.Interface EPIRP2 inherits and the operation that comes can be supported to define the EPIRPDefs2 that those are inherited and the data of coming from EPIRPDefs from interface EPIRP.For example: defined data managedData among the EPIRPDefs, these data managedData is the parameter of the operation OldOperation of interface interface EPIRP, and defined data managedData2 among the EPIRPDefs2, these data managedData2 inherits from data managedData, then operates OldOperation and can support data managedData2.
In addition, this step also can be taked other succession modes, for example: the interface EPIRP that has only the interfaceEPIRP2 succession EPIRP of EPIRP2, the EPIRPNotification that perhaps has only the EPIRPNotification2 succession EPIRP of EPIRP2, the EPIRPDefs that perhaps has only the EPIRPDefs2 succession EPIRP of EPIRP2, perhaps any two kinds of combinations of inheriting modes in these three kinds of succession modes.
Step 202: replace by original EPIRP server end in the pipe unit with the EPIRP2 server end, in by pipe unit, keep original BasicCMIRP server end, and in this BasicCMIRP server end running, install and operation BasicCMIRP2 server end in by pipe unit at this.
In this step, when adopting the EPIRP2 server end in replacing by pipe unit during original EPIRP server end, can cause by the interruption of EPIRP in the pipe unit, but, therefore can not cause by the interruption of network management services in the pipe unit because the entrance function does not directly provide network management services.In addition, because the installation of EPIRP2 server end is to carry out in the running of EPIRP server end in by pipe unit, therefore can not cause the interruption of this system's operation, just can not influence the carrying out of corresponding network management function yet yet, thereby guarantee the continuity of network management task.
Shown in Fig. 2 c, webmaster service function BasicCMIRP server end (supporting interface BasicCMIRP, BasicCMIRPNotification and NRM) is separate and coexist as by in the pipe unit before upgrading back webmaster service function BasicCMIRP2 server end and the upgrading.And in administrative unit, only there is the BasicCMIRP client.At this moment, this BasicCMIRP client in the administrative unit still can be provided by the webmaster service function that is provided by BasicCMIRP server end in the pipe unit.For example, when need be sent notice by pipe unit the time, can send BasicCMIRPNotification and BasicCMIRPNotification2 respectively.At this moment, because BasicCMIRP is only supported in not upgrading of administrative unit, so administrative unit needn't subscribe to BasicCMIRPNotification2, and just receives and treatments B asicCMIRPNotification.And when also upgrading to the BasicCMIRP2 client after the BasicCMIRP of this administrative unit client, then can subscribe to BasicCMIRPNotification2 more separately, and the BasicCMIRPNotification that cancels subscriptions, thereby receive and treatments B asicCMIRPNotification2.
Step 203: use the handle of this EPIRP2 server end to restart EPIRP client in the administrative unit, administrative unit is used the entrance function that is provided by the EPIRP2 server end in the pipe unit by the EPIRP client after restarting, and uses the webmaster service function that is provided by BasicCMIRP server end in the pipe unit by its BasicCMIRP client.
Wherein, shown in Fig. 2 d, the EPIRP client is restarted by the handle that uses the EPIRP2 server end, so that can realize interface with this EPIRP2 server end, and and then the entrance function of using this EPIRP2 server end to provide the information of the corresponding webmaster service function that is provided by pipe unit is provided, thereby can know the BasicCMIRP webmaster service function that this is provided by pipe unit according to this information.
For example: when the above-mentioned entrance function that is provided by the EPIRP2 server end of pipe unit is a specific operation, and at this operation carry out upgrade to the upgrading of its parameter type the time, though then the EPIRP client of administrative unit can be used this operation, but can only support the parameter type of version before the upgrading of this operation, promptly administrative unit EPIRP client can only be before being transmitted upgrading by the EPIRP2 server end of pipe unit the examples of parameters (certain parameter value) of Release parameter type.Then both can have been received and handle the examples of parameters of Release parameter type before the upgrading by pipe unit, also can receive and handle the examples of parameters of upgrading back Release parameter type.Therefore after the examples of parameters of Release parameter type before the upgrading that is received the administrative unit transmission by pipe unit, both can return the examples of parameters of upgrading back Release parameter type to administrative unit, also can be before administrative unit be returned upgrading the examples of parameters of Release parameter type.Receive the examples of parameters of Release parameter type after the upgrading of being returned by pipe unit when administrative unit after, the examples of parameters of this upgrading back Release parameter type can be converted to the examples of parameters of parameter type before the upgrading, use further then and handle.As mentioned above, except can be to being upgraded by pipe unit entrance function operations, also can be to being upgraded by the notice of pipe unit entrance function, at this moment, when administrative unit receives the notice EPIRPNotification2 that is sent by pipe unit, this content of announcement can be converted to the EPIRPNotification that self supports, further handle then.It should be noted that, because the EPIRP client is not subscribed to the notice EPIRPNotification2 of EPIRP2, but only subscribed to the notice EPIRPNotification of EPIRP, so notification service need send to the notice EPIRPNotification2 of EPIRP2 the EPIRP client.
The network management method of backward compatibility network management system according to an embodiment of the invention more than has been described, in said method, has taked being carried out the upgrading of functional class, and its all webmaster service functions are carried out the upgrading of system level by the entrance function in the pipe unit.The present invention also can take being carried out the upgrading of functional class by the entrance function in the pipe unit, makes the server end that is comprised entrance, upgrading back function in the pipe unit; And to being carried out the upgrading of functional class by a part of webmaster service function in the pipe unit, another part webmaster service function is carried out the upgrading of system level, make to be comprised simultaneously in the pipe unit with webmaster service function server end and upgrading back webmaster service function server end before the upgrading of this part webmaster service function of system level upgrading; The webmaster service function information of administrative unit before the upgrading by being provided by pipe unit by entrance function server end inquiry after the upgrading in the pipe unit; Use the webmaster service that is provided by pipe unit by using with the system level upgrading by webmaster service function server end before the upgrading in the pipe unit, and used the webmaster service that is provided by pipe unit with webmaster service function server end after the upgrading of functional class upgrading in the pipe unit, thereby realize network management with the functional class upgrading by using.
