Description
Technical field
The present invention relates in EPON (PON) field, optical line terminal (OLT), to the management method of the optical network unit connect under it (ONU), is a kind of method and system based on interface capability collector reason ONU specifically.Espespecially based on the method and system of ONU interface capability collector reason ONU.
Background technology
PON system is the access network equipment based on passive optical communications mechanism adopting point-to-multipoint, early stage PON technology adopts time-division multiplex technology to complete point-to-multipoint communication, and other multiplex technique, as wavelength division multiplexing and CDMA (Code Division Multiple Access), also in the explorative research of PON system, but not yet extensive use is obtained.
For traditional PON system based on time-division multiplex technology, PON networking mode is OLT(optical line terminal) put ONU(optical network unit) multiple spot networking, its communication general principle is: downlink data is by time-slot division logical channel, end-user listening data on all ONU is broadcasted after time division multiplexing on the time slot of correspondence and issues, selected the data received and control oneself in corresponding logical channel by ONU side; And upstream data adopts the device supporting burst luminous signal on ONU, by time division multiplexing principle, each ONU is luminous at predetermined time slot window according to the order of sequence, and the upstream data of terminal use is sent to OLT side.
Splitting ratio is an important networking and soft exchange enabling technology parameter in PON system, and usual has 1:32,1:64,1:128, even in 10G EPON system standard, splitting ratio has been defined into 1:256.Its meaning is under the PON mouth of an OLT side, can access 32,64,128 even higher ONU quantity.The fan-shaped network construction form of this point-to-multipoint just, makes to realize on OLT to carry out reliable certification, mandate and configuration management have important demand and engineering significance to meeting all ONU under it.
Support that 16 PON mouths calculate according to a less boxlike single deck tape-recorder OLT, each PON mouth is pressed splitting ratio 1:64 and is designed, then the ONU unit accessed under this OLT just has 1024.For a larger convergence type OLT, ONU quantitative requirement of needs management of its lower access is larger, even can reach up to ten thousand.Realizing the configuration management of a large amount of ONU will be a no small engineering, also be the important demand in a PON system engineer applied.In addition, different according to the feature of access user collection, also there is a variety of sorting technique in the interface of ONU and model, SFU(Single Family Unit as under FTTH application scenario), FTTB(Fiber To The Building), FTTC(Fiber To The Curb) MDU(Multiple Dwelling Unit under occasion) etc., kind is very many.So for the flexible support of various ONU kind, it is also the important demand of PON system one of will realize.
In PON system, OLT comprises for the configuration management demand of ONU: for the Authentication and authorization of ONU; For the configuration management of ONU; For the status poll etc. of ONU.Because PON system is based on fan-shaped group-network construction, usually need below an OLT device access and manage thousands of even up to ten thousand ONU.In engineering opening process, OLT first puts in place usually, and ONU layouts gradually, so for the pre-configured function of ONU, namely outline management also must be supported.
For the Authentication and authorization function of ONU, the identify label when support of various Industry code requirements OLT system carries out ONU certification based on the physical label of ONU, logical identifier and these three kinds of ONU main characteristic parameters of password or combination.
For the configuration management function of ONU, mainly comprise the functional configuration management etc. that the user side interface of the configuration management of ONU optical link and ONU is relevant.
For the status poll function of ONU, mainly comprise the version information to ONU, various configuration and interfaces state and inquire about.
Will at OLT and NMS(Network Management System, network management system, referred to as webmaster or network management system) on, realize ONU is managed, concrete certification mark must be known, the interface type of ONU, interface quantity and other relevant ability information.In the system of practical PON, OLT is to the configuration management model of ONU, normally based on ONU equipment model, analyze the model of its interface capability, and then by standardized OAM or OMCI(ONU/ONT Management Control Interface), or even privately owned communication standard carries out the configuration management to ONU.
Illustrate below by way of off-line arrangement ONU.
Usual off-line arrangement operation is first based on special identifier and the ONU equipment model establishment ONU mandate list item of ONU; Then the light path of this ONU and user's side data business are configured.After completing these work, when ONU is arranged in corresponding access site and after powering on, ONU can send registration message of reaching the standard grade, OLT, according to the data of off-line arrangement, completes certification, mandate to ONU; Then the concrete port traffic data configuration of this ONU is issued.After these configuration successfuls are issued to ONU and are executed correctly, ONU can provide concrete data service for user, comprise VOIP(Voice Over IP), broadband access network or IPTV etc. business.
On OLT, realize method schematic diagram based on ONU equipment model model configuration management ONU see Fig. 1 .a and 1.b, wherein: Fig. 1 .a is the flow process of being carried out the ONU configuration based on model management by NMS or OLT local command line; How Fig. 1 .b, after the ONU managed based on model reaches the standard grade, obtains the flow process of configuration.This modelling carrying out managing based on ONU equipment model realizes easily directly perceived, particularly can solve the pre-configured demand of off-line ONU.But it also has wretched insufficiency:
1) upgrading NMS and OLT software is needed, the configuration management to newly-increased ONU model device could be supported, because if in the management object of NMS management object and OLT, can not find the ONU of respective model, just accurately cannot be managed for configuration the interface of ONU, thus often support that a new ONU needs upgrading NMS or OLT software.And OLT and the NMS upgrading be on fan-shaped framework root node all certainly will have influence on its various customer services mounted below, be thus considered to the operation needing prudent treatment in PON operational system;
2) there is restriction in OLT and the ONU intercommunication for different producer, even if standardized OAM or the OMCI interface standard that intercommunication both sides define, based on the ONU that concrete model manages, all must first be recognized by OLT and NMS, could successfully access, this point can not meet operator or the user requirement for the convenient networking of terminal equipment.Along with PON system is in the increasing development need of Access Network aspect, the research institution of a lot of related device manufacturer and standard formulation, is also proposing various discussion to how to carry out management for ONU more flexibly.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
First, ONU management concept in some PON system is illustrated as follows.
About the creation mode of ONU administrative model, usually there are two kinds at present, namely manually add and automatically find two kinds of patterns.
Manually adding ONU administrative model is specified from top to bottom by NMS or OLT.This mode is used for the occasion of ONU off-line configuration management.General employing inputs manual for the information such as the certification mark of ONU, ONU equipment model (referred to as ONU model), configuration in advance at present, creating becomes an ONU corresponding with ONU equipment model and authorizes list item, thus when authorizing ONU that the ONU equipment model in list item is mated to reach the standard grade with ONU, namely obtain the information such as corresponding mandate and configuration by the ONU authorization message table be stored on NMS or OLT.Be usually used in pre-configured i.e. off-line arrangement occasion.
Automatic discovery ONU administrative model, be then after ONU reaches the standard grade, to ONU, go to obtain the information such as certification mark, ONU equipment model, configuration of ONU by sending instructions under OLT or NMS, then the validation of information of acquisition is got off, and create and become an ONU corresponding with the ONU equipment model of this ONU and authorize list item.And can be configured ONU further, the related administrative information of such ONU just creates and completes.In the engineering that this pattern is opened at a large amount of ONU simultaneously, comparatively conventional.
The difference of these two kinds of patterns is only for newly authorizing ONU, and it authorizes list item different with the flow process of the establishment of configuration data.
In addition, the solution of the present invention needs have basic standard to support requirement to the ONU be managed, and can meet the message format based on OAM, OMCI or SNMP standard and content that operator issued.These standards are operator's networking requirements basic to OLT and ONU, most obtain the license that networks ONU and OLT device all can support these standard criterions, here just do not elaborated.
The differentiated demand of the configuration management of ONU is mainly manifested in the differential management demand for ONU form, the ONU that this differentiation embodies a concentrated reflection of different application occasion will provide dissimilar joint side interface and user's side business interface for user, and different interface quantity, and for ONU other configuration, as the configuration of certification mark, the configuration on optical link etc. are all have unified standard can carry out managing at present.Therefore, the present invention is according to this application demand, and the interface capability proposed based on ONU is basic as the modeling of ONU configuration management, namely carries out classification configurations by " ONU interface capability collection (being called for short interface capability collection) " to ONU.Give an example, the ONU of every " having 1 1G EPON up going port, 4 100M ethernet user mouths and 2 POTS mouths " is all classified as same class ONU and ignores the difference of its ONU equipment model by us, all adopts OAM or OMCI of standard or snmp message form to be managed for configuration with same ONU interface capability collection template to it ONU of " having 1 1G EPON up going port, 4 100M ethernet user mouths and 2 POTS mouths " this ONU interface capability collection.
As shown in Fig. 2 .a, 2.b, the method based on ONU interface capability collector reason ONU of the present invention, comprises following content:
The definition of ONU interface capability collection and operation principle:
ONU is divided by interface capability, described interface capability refers to the joint side interface type that ONU provides for user and interface quantity and user's side business interface type and interface quantity, the ONU with same interface capability is divided in same ONU interface capability collection (set), then on OLT and NMS, create ONU interface capability collection template respectively as ONU administrative model by ONU interface capability collection, and be that often kind of ONU interface capability collection template specifies ONU interface capability collection template name; Then, manage with " ONU interface capability collection template " form.
Described ONU interface capability integrates the set that the joint side interface type and interface quantity and user's side business interface type that refer to and provide as user by ONU and interface quantity divide, its joint side interface type provided for user of each ONU of concentrating of ONU interface capability and interface quantity identical with user's side business interface type and interface quantity.
On the basis of technique scheme, described ONU interface capability collection template name is configured voluntarily by user, for O&M is convenient, ONU interface capability collection template name can be named by ONU equipment model number mode, then ONU interface capability collection template name has the identity with ONU equipment model equivalence.
As mentioned above, it is considered herein that the ONU with same interface capability is exactly same class ONU, and be respectively each class ONU and create a corresponding ONU interface capability collection template, in PON system of the present invention, manage with " ONU interface capability collection template " form, each ONU interface capability collection template can be named flexibly, conveniently manages, and ONU interface capability collection template name can be named by ONU equipment model number mode.ONU interface capability collection template name has the identity with ONU equipment model equivalence, can be compatible based on ONU equipment model management ONU.
ONU interface capability collection template name to have with the advantage applies of the identity of ONU equipment model equivalence in following application:
The place being object with ONU equipment model originally in system, all can expand " ONU interface capability collection template name " as new management object.Such as, when adding ONU in ONU mandate list item, add the place of " ONU equipment model ", can replace and add a kind of " ONU interface capability collection "; Again such as: the place of the interface configuration of corresponding ONU, be originally the interface object generated according to ONU equipment model, can expand to and generate interface object be managed etc. based on ONU interface capability collection.
In order to the communication standard between better compatible OLT and NMS and agreement, the coding of the ONU equipment model part supported in system can be regarded as the reserved numbering of ONU interface capability collection template name by us.ONU all like this carries out based on ONU interface capability collection template the system that manages by being included into.And can follow according to situation flexibly, the constantly newly-increased ONU model needing to be managed.Namely the problem that newly-increased ONU networks and the system NMS that brings of different manufacturers ONU access demand and OLT complete upgrading require is solved, again will from NMS and Equipments Setting aspect, compatible employing ONU equipment model carries out the method for ONU management comprehensively.
Such as: for the ONU managed based on model, the special capability set template of use is managed it, the ONU based on the management of ONU equipment model used in a network with compatibility.Be the capability set template that system known models ONU has been pre-created acquiescence at capability set template memory space, and ONU equipment model is managed as unified acquiescence template name.
On the basis of technique scheme, when employing manually adds ONU administrative model, described ONU interface capability collection template is created from top to bottom by OLT, and synchronous to NMS;
When adopting automatic discovery ONU administrative model, after described ONU interface capability collection template collects the interface capability information of access ONU by OLT or NMS, according to rule, by the spontaneous establishment of NMS or OLT.
That is: in the pattern of " manually adding ONU ", ONU interface capability collection template is created from top to bottom by NMS or OLT.And in " ONU finds automatically " pattern, then ONU interface capability collection template is after collecting the interface capability information of access ONU by OLT or NMS, according to rule, by the spontaneous establishment of NMS or OLT.The difference of both has been described in detail in Fig. 2 .a and Fig. 2 .b.Do manual configuration from NMS to OLT, which is usually used in ONU off-line arrangement scene.Trigger after being reached the standard grade by ONU and automatically find, this ONU of being usually used in concentrates the scene activated the service in real time.By the contrast of Fig. 2 .a, Fig. 2 .b and Fig. 1 .a, Fig. 1 .b, can see in the present invention, extend the treatment mechanism after supporting ONU interface capability collection Template Manager and the difference for the treatment of mechanism carrying out ONU configuration management based on ONU equipment model.
What Fig. 2 .a described is support the ONU collocation method schematic diagram based on ONU interface capability collector reason in the present invention.First follow according to managerial demand, create corresponding ONU interface capability collection template; Determine the designation method of parameters for authentication and ONU capability set template again the need of pre-configured (off-line arrangement) occasion with certificate, namely, if pre-configured (off-line arrangement), need to specify the authentication feature parameter of ONU and the ONU interface capability collection template of ONU, if the ONU equipment model that system is known, then capability set template can be replaced to manage by ONU equipment model parameter; If Configuration Online, then the information that can be reported by actual ONU, is confirmed parameters for authentication and the ONU interface capability collection Template Information of ONU in lower white list, need not input by hand; After completing above operation, and then the optical link parameter to ONU, and the service parameter of the user side interface of ONU is configured.
The handling process schematic diagram of line process on the ONU that what Fig. 2 .b described is based on ONU interface capability collector reason.After ONU reaches the standard grade, OLT receives ONU registration message, and OLT gathers parameters for authentication relevant information and the ONU equipment model of ONU, and the information such as interface capability, then compare with the ONU authorization message be stored on OLT; If authentication information mates, more whether there is pre-configured process with certificate.If have pre-configured, then, after checking administrative model coupling, what be configured issues process; If do not have pre-configured, then follow and whether supported that the configuration management model of this ONU processes according to OLT; If the model supported or ONU interface capability collection template, then can carry out Configuration Online, if do not have the model mated, then OLT should be this ONU and automatically creates new ONU interface capability collection template, is then configured operation.
On the basis of technique scheme, described ONU interface capability collection template adopts the whole network unified management.
The present invention gives the whole network unified management and the realization mechanism thereof of ONU interface capability collection template: have employed based on encryption algorithm (as MD5, CRC algorithm etc.) generative capacity collection template full network marking, and the key word index of communication as ONU type relevant configuration, unified to guarantee the ONU interface capability collection template data efficient information of the whole network OLT and NMS.
NMS system, it will manage for the whole network OLT, and is managed for all ONU of its lower access by OLT.Because each OLT independently can carry out the establishment of ONU interface capability collection template, so when multiple OLT is to the configuration information of this locality of NMS system synchronization oneself, such situation may be there is: same ONU interface capability collection template title on different OLT is different, also may on different OLT, ONU interface capability collection Template Information there are differences.This species diversity can be allowed in separate unit OLT device, so that the maintenance of engineering, but these differentiation should conceal in NMS aspect, allows ONU of the same type show consistent attribute in NMS aspect.This just relates to adopt what scheme, can ensure the problem of the efficiency that the whole network of ONU interface capability collection template is unified and synchronous.
The present invention proposes a kind of mechanism of the whole network unique identification ONU interface capability collection template here, and we are called ONU interface capability collection template identification code.Each ONU interface capability collection template adopts the mechanism of the whole network exclusive identification code to realize the unified management of ONU interface capability collection template the whole network, utilizes this identification code to realize the whole network of ONU interface capability collection template operation unified.
ONU interface capability collection Template Information is divided into key message and the large class of peculiar information two by us.Key message is the information participating in the calculating of capability set template exclusive identification code, such as the digital information such as interface type numbering and interface quantity.Peculiar information, for each OLT device, does not participate in exclusive identification code and calculates, as capability set template name, and the particular vendors information etc. of ONU.
Key message is the information participating in the calculation of ONU interface capability collection template identification yardage, the such as digital information such as interface type numbering and interface quantity, the key message that the ONU interface capability collection that these can determine by we comprises, adopt as MD5, the digital coding algorithms such as CRC calculate one " numeric string ", and this numeric string is exactly our ONU interface capability collection template identification code.ONU interface capability collection template identification code will play the index effect of unique identification one specific ONU interface capability collection template between OLT and NMS in a network.Note, ONU interface capability collection template name is not key message, does not participate in the calculating work of exclusive identification code.
In addition, consider because digital coding exist certain collision probability (although algorithms selection must good time, collision probability is extremely low), namely different initial data calculates identical " numeric string ".We add a correction parameter especially in the parameter of ONU interface capability collection template, and it will participate in the calculating of identification code.When system is when creating ONU interface capability collection template, the ONU interface capability collection template identification code calculated there occurs with the ONU interface capability set identifier code on Already in native system and conflicts, then at correction parameter (correction bit) enterprising Row sum-equal matrix, recalculate a unique identification code.Correction parameter in ONU interface capability collection template is also key message.
Information outside key message is then peculiar information, as ONU interface capability collection template name, and the particular vendors information of ONU, function etc., it can be classified as privatization information by us, for each OLT device self, and does not participate in the calculation of ONU interface capability collection template identification yardage.
After OLT accesses NMS system, first the ONU interface capability collection Template Information that OLT stores collects by NMS, compare with the ONU interface capability collection template in the database of controlling oneself, if when finding OLT there is new ONU interface capability collection template identification code, namely in NMS system, synchronously add this ONU interface capability collection template, and for identical ONU interface capability collection template identification code, need NMS to do and compare further, see the collision of whether depositing with other template.If there is collision, then need by the unified adjustment of NMS.When complete OLT access NMS first subsynchronous after, NMS issues each OLT by unified for the ONU interface capability collection template data of this locality, and each OLT follows and issues data according to NMS, integrates template identification code as keyword with ONU interface capability, create and adjust oneself local data, corporate data is carried out synchronously.Thus reach the synchronous object of the whole network.After completing this operation, on all OLT, all unification is synchronized the ONU that the whole network will support.In ensuing PON system, when needing to use ONU type information, all can carry out alternately as parameter with the identification code of ONU interface capability collection template.On this problem, decrease the individual alienation data maintenance of NMS to OLT, improve the efficiency of NMS simultaneously.
Under Fig. 3, Fig. 4 just find two kinds of configuration mode situations with regard to ONU manual configuration and ONU respectively automatically, the interacting message of present system between ONU, OLT and NMS and important handling process are supplemented.
When Fig. 3 describes manual creation ONU administrative model, about the committed step of the interacting message of ONU configuration management between OLT and NMS.First be synchronous phase, when a new OLT adds NMS management, NMS needs the ONU white list that will OLT stores, and capability set Template Information is got up, with carry out in nms database synchronous.NMS, after completing synchrodata confirmation, will issue confirmation of synchronization information to OLT, wherein as previously mentioned, if capability set template needs to correct, also be issued by confirmation.Next be the operation manually being increased ONU white list information by NMS.In this stage, need to configure ONU authentication information by NMS to OLT, and specify the administrative model of ONU.The administrative model of ONU is followed and is adopted capability set template still to adopt the management of ONU equipment model to have different process branches according to this ONU.After completing the interacting message of above configuration, next follow and can operate the concrete configuration of ONU according to needs.
When Fig. 4 describes and automatically finds ONU administrative model, about the committed step of the interacting message of ONU configuration management between OLT and NMS.First be synchronous phase, the process of this Fig. 3 is consistent.Next be report situation by the actual of ONU, confirm by NMS the operation adding ONU white list.In this stage, the white list of ONU and administrative model are online acquisition and establishment.Certification mark, the ONU equipment model and interface capability information etc. of online ONU will be obtained to ONU by NMS, OLT.NMS follows the authentication information according to ONU white list under the ONU certification identity validation obtained, and follows the interface capability according to this ONU collects simultaneously, is confirmed to be and adopts capability set template still to adopt ONU equipment model to manage.If the interface capability of this ONU is in the database of OLT and NMS, can not find the capability set template or model of mating completely, then NMS and OLT will create a new capability set template for it automatically.After completing the interacting message of above configuration, next follow and can operate the concrete configuration of ONU according to needs.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
