Abstract
An entity relationship model transformation method for managing an ONU comprises the steps that a circuit template module is utilized for judging the data mapping mode; when data are mapped into a minimum service bearing unit of the access node connector end only through priority, a second entity relationship model or a fourth entity relationship model is built; when the data are mapped into the minimum service bearing unit of the access node connector end only through the virtual local area network, a first entity relationship model or a third entity relationship model or a sixth entity relationship model is built; when data are mapped into the minimum service bearing unit of the access node connector end through two layers of filtering of the virtual local area network and the priority, a fifth entity relationship model or a seventh entity relationship model is built. A new data mapping relationship can be issued when scene demands change, and reconfiguration of an ONU service model is achieved.
Description
Technical field
The present invention relates to the entity relationship model conversion method of a kind of ONU of management, relate in particular to the entity relationship model conversion method of managing ONU under the many scenes of a kind of PON system.
Background technology
PON(EPON, Passive Optical Network) system management ONU(optical network unit, Optical Network Unit) time, need to manage control interface (ONU management and control interface is called for short OMCI) by ONU ONU is set up to entity relationship model.
OMCI module is the software module of OLT, at ONU administration module with between driving, that gigabit passive optical network (GPON) system is in order to realize OLT (optical line terminal, Optical Line Terminal) side ONT(Optical Network Terminal, Optical Network Termination) management control interface (OMCI) function and the module that designs.
The entity relationship model of the ONU defining in standard G.988 can be summarized as following 7 classes:
The Business Stream of the first model multiport is all mapped to a gemport, i.e. N:1 bridging model.
Gemport is minimal service carrying unit.GEM(GPON Encapsulation Method) be G-PON Encapsulation Mode.Gemport can be mapped in T-CONT flexibly.T-CONT is the business buffer that can carry multiple gemport.One or more business is mapped in a gemport, and a gemport can be mapped in a T-CONT and go, and multiple gemport also can be mapped in same T-CONT.
Second model is that single port ONU is based on pri(priority service priority) carry out business mapping, i.e. 1:M mapping model.
The third model is that single port ONU is based on vlan(Virtual Local Area Network, VLAN) carry out business mapping, i.e. 1:P filtering model.
The 4th kind of model is that multiport ONU carries out business mapping based on pri, i.e. N:M bridge-mapping model.
The 5th kind is the business mapping of single port ONU based on vlan and pri, i.e. 1:MP map-filtering model.
The 6th kind is that multiport ONU carries out business mapping based on vlan, i.e. N:P bridge-filtering model.
The 7th kind is that multiport carries out business mapping based on vlan and pri, i.e. N:MP bridge-map-filtering model.
Wherein, N represents the user port number of ONU, and port number is 1, and N is 1, and port number is greater than at 1 o'clock, represents with N.
The user port that M represents ONU is based on pri(priority service priority to ANI end (ANI:Access Node Interface access node interface)) carry out business mapping.
The user port that P represents ONU is to divide the VLAN network segment based on vlan(to ANI end (ANI:Access Node Interface access node interface)) carry out business mapping.
Under different application scenarioss, required entity relationship model has certain difference, need to re-establish corresponding relational model.
In practical application scene, business directly need to be forwarded to gemport, realize the mapping of data service to gemport according to pri or vlan, or carry out the mapping of business to gemport based on pri and vlan simultaneously.In the model of two layer services, can not support the demand of all application scenarioss simultaneously, therefore need to realize according to user's actual demand the arrangement of the upper business model of ONU.
In existing design, ONU is upper, and what set up is the business model of 1:P/N:P, only can supporting business be all forwarded to gemport and vlan shines upon two kinds of application to gemport.
User specifies the allocId(Alloc-ID:Allocation Identifier distribution marker on ONU, for identifying T-CONT), gemport and each gemport under each allocId allow by the vlan information of data.From line profile module, (circuit masterplate module is the software module of OLT to OMCI module, parallel with OMCI module, it is all business module, this circuit masterplate module provides type and the parameter of the ONU business model of user command row input to OMCI module) receive these data after, the gemport specifying by user creates the service channel of end from Ethernet interface to ANI, and each gemport sets up a path.Then gemport is set up to mapping with corresponding T-CONT, business is finally mapped in corresponding T-CONT by gemport.T-CONT is Transmission Containers transmission container, is a kind of buffer Buffer of bearer service, is mainly used to the unit of transmit ascending data, and introducing T-CONT is mainly in order to solve upstream bandwidth dynamic assignment, to improve line efficiency.
Current business model only can change to some extent according to the number difference of user port, and does not support the switching under various scenes, therefore can not meet all application demands.
