Along with development of Communication Technique, the optical fiber access technology has determined that it will be as the final solution of broadband access network technology owing to the huge capacity of optical fiber, can grow the advantage of Distance Transmission.The collocation form of existing fiber Access Network has multiple, for example passive optical-fiber network (Passive Optical Network is hereinafter to be referred as PON), Active Optical Fiber network (Active Optical Network is hereinafter to be referred as AON) etc.
Existing Optical Access Network network adopts Optical Fiber Transmission and the access technology that a little arrives multiple spot more, be example with the PON collocation form, its network architecture generally as shown in Figure 1, can comprise optical line terminal (Optical LineTerminal, hereinafter to be referred as OLT) 100, optical network unit (Optical Network Unit is hereinafter to be referred as ONU) 200 and passive optical splitter 300 (Splitter).OLT 100 wherein is the local side apparatus that are arranged at Virtual network operator service side; ONU 200 is terminal equipments of user's side in the network; Link to each other by light separator 300 between ONU200 and the OLT 100, between OLT 100 and light separator 300, be connected with trunk optical fiber, between ONU 200 and light separator 300, be connected with branch optical fiber, a plurality of branch optical fibers converge in light separator 300, melt to be connected on the trunk optical fiber together.At present, Gigabit Passive Optical Network (Gigabit PON, hereinafter to be referred as GPON) owing to have higher bandwidth efficiency, and the synchro timer mechanism that it adopts is continued to use traditional SDH (Synchronous Digital Hierarchy) (synchronous DigitalHierarchy, be called for short SDH), with and kilomega passive optical network packaging method (the G-PONEncapsulation Method that adopts, hereinafter to be referred as GEM) many advantages such as business that can adaptive different rates, therefore become carriers in the world gradually and use maximum access networks at present.
In the existing GPON implementation, issue downstream message by OLT to ONU, and control and bearer data transmission to the interacting message that OLT uploads upstream message by ONU.OLT and ONU alternant way can for: at first the probe message of setting form by the OLT broadcast transmission is given all coupled ONU; ONU sends response message to OLT after receiving this probe message, make OLT recognize the existence of this ONU, finishes the register flow path of this ONU to this OLT subsequently; After finishing registration, ONU generally can manage control interface (ONU Management and Control Interface is hereinafter to be referred as OMCI) passage by ONU and report self attribute of performance to OLT, for example can reporting uplink speed etc.; After registration, can carry out normal transfer of data.In the above-mentioned interacting message that carries out, after all need encapsulating according to certain agreement, each mutual upstream or downstream message sends again, receive when OLT or ONU receive upstream or downstream message that need resolve according to certain agreement, decapsulation etc. handled could correct identification message content.
At present, becoming increasingly abundant of customer service causes the user more and more higher to the demand of volume of transmitted data, development along with the fiber plant technology, more senior Optical Access Network network technology, for example 10G or optical module more at a high speed occur, promoted existing GPON to the more PON evolution of high speed, wherein more senior and passive optical access network network at a high speed can be referred to as next-generation passive fiber optic network (Next Generation PON is hereinafter to be referred as NGPON).Service provider's side network element devices such as OLT among the NGPON of upgrading can connect more user's side network element device, for example the OLT of original GPON system support and the maximum branch ratio of ONU are 1: 64, and have supported branching ratio now up to 1: 512 or 1: 1024, can transmit simultaneously more data stream, but the quantity of ONU quantity that former protocols having can have been distributed to the sign of ONU and data flow and address limitation and data flow, so the Optical Access Network network generally faces the problem of dilatation.High speed ONU is because upstream rate is bigger, therefore physical layer characteristic can be different, for example need the physical layer overhead more grown, in order to effectively carry out power threshold judgement and clock recovery etc., then the frame format of upstream message and downstream message needs to adjust, and is also corresponding different in concrete operations management and configuration, needs accordingly to adopt different agreements to resolve, in addition, the encapsulation/decapsulation agreement to upstream message and downstream message also has corresponding variation.Therefore, the problem that generally faces in Optical Access Network dilatation scheme is: from reducing cost and the angle that takes full advantage of of existing investment being considered, often can not be to existing user's side network element device, particularly can not all replace ONU, need be based on the dissimilar ONU coexistences of different fiber transmission technology, this just requires the fibre optic transmission equipment of service provider's side can identify dissimilar user's side network element devices of existing and new introducing, and the user's side network element device that is respectively dissimilar provides data transport service.Yet, how realize in the dilatation scheme that the coexistence compatibility of user's side network element device is assistant officer's problem to be solved after existing user's side network element device and the dilatation.

Embodiment
The optical-fiber network method for transmission processing that various embodiments of the present invention provide can be applicable to the compatibility coexistence of carrying out the polytype user side network element device of transfer of data based on the different pieces of information transmission technology, for example solve the coexistence problems of GPON network element device and NGPON network element device, NGPON wherein can be 10G-GPON, WDM-PON (Wave division multiplexing passive optical network, Wavelength Division Multiplexing-PON), Hybrid-PON (mixed type PON) etc.Clear for describing, below will be called G-ONU based on the ONU of GPON technology, be called NG-ONU based on the ONU of NGPON technology.
First kind of optical-fiber network method for transmission processing embodiment one
Be illustrated in figure 2 as the flow chart of first kind of optical-fiber network method for transmission processing of the present invention specific embodiment one, the different situation of frame format of the Data Transport Protocol regulation that be applicable to present embodiment GPON technology and NGPON technology adopt, be specially the performed method of the side OLT of service provider, this method for transmission processing specifically comprises:
Two type probe message after step 130, OLT will encapsulate are respectively to all ONU broadcast transmissions that this locality connected, and, the type identification sign indicating number is arranged in the type identification message returns to OLT when each ONU resolves the corresponding type probe message of acquisition with indication;
In above-mentioned steps 130, other field contents can not change in the type probe message of OLT broadcast transmission, have only type identification sign indicating number difference, and two type probe message can be received by all ONU that is connected on the OLT.For G-ONU and NG-ONU, it can only be resolved the type probe message based on a kind of Data Transport Protocol of self, that is: because the form of the type probe message of corresponding different pieces of information host-host protocol itself is different, though so ONU can receive all types probe message, can only resolve one of them type probe message.So, G-ONU can abandon it because resolving the type probe message of obtaining based on the NGPON protocol encapsulation, and in like manner, NG-ONU also can abandon it because resolving the type probe message of obtaining based on the GPON protocol encapsulation.In fact each ONU can only correctly resolve and obtain a type probe message.Certainly, in step 120, OLT should encapsulate it according to the represented different pieces of information host-host protocol of the type identification sign indicating number that arranges in the type probe message further accordingly, if in certain type probe message, be provided with a kind of type identification sign indicating number of data transmission, but adopt another kind of Data Transport Protocol to set and encapsulation, under this situation arranged in a crossed manner, will make any ONU all can't resolve any kind probe message.After corresponding type probe message is obtained in the correct parsing of ONU, according to the agreement regulation, the type identification sign indicating number is arranged in the type identification message of generation, again type identification message is uploaded to OLT.
The data transmission that step 150, OLT support according to type identification sign indicating number identification ONU, determine that namely ONU also is based on the NGPON technology based on the GPON technology, after correct each ONU data transmission of identification, can continue to carry out the data transfer operation of upstream message and downstream message.
Above-mentioned steps 140 and 150 specific implementations are: certain specific field is set point in the upstream message frame overhead field when OLT receives and detects, when for example being first kind offset, frame format by the GTC upstream message is resolved, the GEM frame that demultiplexing is gone out carries out decapsulation, carries out dissection process when having PLOAM message; When certain specific field is second types value in detecting the frame overhead field, resolve by the frame format of NG-GTC upstream message, the NG-GEM frame that demultiplexing is gone out carries out decapsulation, carries out dissection process when having NG-PLOAM message.
In the present embodiment, be uploaded to OLT again because have only the ONU of respective data transfer type to resolve to obtain corresponding type identification sign indicating number, every class ONU has only uploaded the type identification message corresponding with its data transport-type, so above-mentioned steps can realize that OLT is to the type identification of each ONU.
In concrete the application, can utilize original message, for example adopt delimiter to determine message, namely physical layer operations management maintenance (Physical Layer OperationAdministration and Maintenance is hereinafter to be referred as the PLOAM) message of " Upstream_Overhead " by name is as the type probe message.OLT is for the ONU that newly is connected thereto, usually before this ONU registration, send " Upstream_Overhead " message, Gigabit Passive Optical Network Transmission Convergence (the GigabitPON Transmission Convergence that OLT sends, hereinafter to be referred as GTC) general format of downstream message is shown in Fig. 3 a, comprise frame overhead part " PCBd " and frame payload part " Payload " wherein, the frame format of frame overhead part is shown in Fig. 3 b.In " Upstream_Overhead " message, the content of " PLOAMd " field carrying PLOAM message of frame overhead part, the concrete form of this field is shown in Fig. 3 c, " Message " field in the PLOAM message, one of its effect just is used to the delimiter that ONU sends to the upstream message distribution provisions of OLT, in the present embodiment, can stipulate that in this field the delimiter of different value is as the type identification sign indicating number of different pieces of information transport-type for dissimilar ONU.In the PON transmission technology, when ONU receives " Upstream_Overhead " message from OLT, can from " Message " field, obtain the delimiter of distributing to its use according to agreement, thus with this delimiter as the delimiter that will use in later and this OLT interactive messages.The frame format of the GTC upstream message that general ONU uploads is shown in Fig. 4 a, comprise " PLOu ", " PLOAMu ", " PLSu ", " DBRu " and frame payload " Payload " part, wherein, " PLOu " field comprises the delimiter field of " Delimiter " shown in Fig. 4 b.In the present embodiment, ONU can upload for the type identification sign indicating number that distributes delimiter field is arranged on the upstream message that returns to OLT as delimiter " Delimiter " field being arranged on downstream message.
This technical scheme is specially adapted to the situation that ONU burst upstream message is given OLT, and ONU will use OLT to distribute the delimiter of its use to upload message to OLT.This technical scheme has been utilized existing delimiter allocation flow, it is to consult to determine a delimiter value by OLT and ONU that existing delimiter distributes, be in use in the follow-up upstream message, the technical scheme of present embodiment is that the ONU of different pieces of information transport-type has specified different delimiter values, this delimiter still has the function of former delimiter on the one hand, becomes the type identification sign indicating number of ONU on the other hand.In mutual with the subsequent message of ONU, all continued to use this delimiter in each upstream message, so OLT can be according to the data transmission of the identification of the delimiter in each upstream message ONU, to handle accordingly.The realization of present embodiment is not limited to arrange the delimiter that distributes in " Upstream_Overhead " message, the type identification sign indicating number can also be arranged in the field of appointment in other message that OLT is broadcast to ONU and send to ONU, or generation is exclusively used in the broadcast of carrying out the type detection, indicate ONU to obtain the type identification sign indicating number according to default agreement from the field of appointment simultaneously, and be set in the setting field that self is uploaded to OLT message and identify for OLT.As long as the analysis mode difference that all types of ONU adopt just can realize only obtaining corresponding type identification sign indicating number and return to OLT.
By adopting the technical scheme of present embodiment, realized the identification of the ONU data transmission of OLT in the mode of OLT initiation, thereby can handle accordingly at the data transmission of ONU, for example carry out the message of uploading that ONU is handled in corresponding decapsulation according to the data transmission of ONU.The technical scheme of present embodiment is not limited to the data transmission identification to G-ONU and NG-ONU, can also extend to realization to the correct identification based on the multiple network element device type of different agreement and frame format, and the change to existing optical-fiber network network element device is minimum, and especially the operating process of ONU is hardly with change.Therefore, this technical scheme can effectively realize the compatibility coexistence of dissimilar optical network devices, and scheme is simple, cost is low, is easy to realize.
