The technical scheme that should be appreciated that the embodiment of the present invention can be applied to various optical communication systems, passive optical networks such as GPON, EPON, 10G-GPON, 10G-EPON, ODSM-PON, TWDM-PON.For convenience, following embodiment is example by the HPON system of take based on GPON, and take the network equipment that comprises the terminal equipment of ONU and ONT and comprise OLT and describe as example, but the embodiment of the present invention is not limited to this.
For example, in one embodiment, HPON system can be the ODSM-PON system that adopts dynamic spectrum management (Optical Dynamic Spectrum Management, referred to as " ODSM ") technology.Refer to Fig. 1, in ODSM-PON system, ODN can adopt two-stage light splitting, and the first order is mixed light multiplexer, and the second level is passive optical splitters part.With up, the descending situation of four pairs of wavelength that respectively adopts, illustrate below.From OLT to ONU, be called descending, four wavelength of descending employing, and coexisting in WDM mode; ONU is divided into four groups according to downstream wavelength, and in each downstream wavelength, OLT is broadcast to all corresponding ONU that receive wavelength in TDM mode by downstream data flow, but each ONU receives only the data with self identification.Otherwise, from ONU to OLT, be up, OLT adopts adjustable demodulation multiplexer (Demultiplexer, referred to as " DEMUX ") that upgoing wave dash is divided into four passages, and each passage is received by a receiver, and the ONU in different data feedback channels coexists in WDM mode.In order to guarantee that the upward signal of each ONU in same data feedback channel does not clash, each ONU adopts TDMA mode in this data feedback channel, by OLT, be each ONU distribution time slot in passage, the time slot that each ONU must distribute in strict accordance with OLT sends data.
On down direction, the continuous signal light of four transmitter Tx1 of OLT～Tx4 transmitting is by multiplexer (Multiplexer, referred to as " MUX ") and WDM device coupling after output to the trunk optical fiber of ODN, after trunk optical fiber transmission, arrive mixing arrangement (Hybrid-Box), in Hybrid-Box, after WDM coupler partial wave, by erbium-doped fiber amplifier (Erbium-doped Optical Fiber Amplifier, be called for short " EDFA ") amplify, then after another MUX demultiplexing, be coupled into branch optical fiber, through branch optical fiber, be transferred to second level passive optical splitter, through Drop cable, be transferred to each ONU again.On up direction, the burst luminous signal of ONU transmitting is coupled into branch optical fiber through Drop cable by second level passive optical splitter, after branch optical fiber, enter Hybrid-Box, after being coupled by passive optical splitter after WDM device partial wave, by semiconductor optical amplifier (Semiconductor Optical Amplifier, abbreviation " SOA ") amplify and enter trunk optical fiber by WDM device, after trunk optical fiber transmission, arrive OLT, after the WDM of OLT inside device and adjustable DEMUX, by four receiver RxA～RxD, received respectively.
If ODSM-PON system realizes on the basis of GPON, according to existing hardware handles ability, can accomplish up, descendingly totally 16 to (even more) wavelength, can support thus 1024 even more ONU, can accomplish that 1:1024(is even higher) branching ratio.
ODSM-PON adopts WDM and TDM technology, can keep existing ODN and ONU constant, can significantly reduce deployment and the O&M cost of PON system when promoting bandwidth, and protection existing investment, is one of technique direction of existing PON evolution.Of course it is to be understood that scheme that the embodiment of the present invention provides can also be applicable to other based on TDM-PON(such as EPON or GPON) HPON system.
Fig. 2 shows according to the indicative flowchart of the method 100 of the identifier of the conversion terminal equipment of the embodiment of the present invention.As shown in Figure 2, the method 100 comprises:
S110, the upstream data that local side apparatus receiving terminal apparatus sends, the control section of this upstream data comprises the device identifier of indicating this terminal equipment;
S120, local side apparatus, according to the bandwidth authorizing information corresponding with this upstream data, obtains and the corresponding expansion equipment identifier of this upstream data;
S130, local side apparatus determines that this device identifier and this expansion equipment identifier that the control section of this upstream data comprises match;
S140, this device identifier that local side apparatus comprises the control section of this upstream data replaces with this expansion equipment identifier.
In specific embodiment, local side apparatus can be respectively optical line terminal OLT and optical network unit ONU with terminal equipment.OLT is when receiving the upstream data of ONU transmission, can according to the corresponding bandwidth authorizing information of this upstream data, obtain and the corresponding expansion equipment identifier of this upstream data, and when the device identifier comprising at the control section of determining this upstream data and this expansion equipment identifier match, this device identifier that the control section of this upstream data is comprised replaces with this expansion equipment identifier.
Therefore, the method of the identifier of the conversion terminal equipment of the embodiment of the present invention, by the identifier to terminal equipment, replace, can support the terminal equipment of greater number, to realize the support to large branching ratio passive optical network at media access control layer, and can not change ONU, compatible with existing passive optical network standards, thereby can improve the capacity of system, and reduce the cost of system.
Particularly, in order to solve the MAC layer of PON system, support excess ONU, transmission container (Transmission Container, referred to as " T-CONT "), GPON method for packing port (Gigabit-capable Passive Optical Network Encapsulation Method Port, referred to as " GEM-PORT ") and don't change ONU, the embodiment of the present invention can adopt following scheme: in OLT inside with expansion ONU-ID, the ALLOC-ID of expansion and the GEM-PORT-ID of expansion distinguish mark ONU, T-CONT, GEM-PORT, and at ONU still with original ONU-ID, ALLOC-ID and GEM-PORT-ID distinguish mark ONU, T-CONT, GEM-PORT, in addition, OLT can shine upon according to bandwidth (Bandwidth Map when uplink receiving, be called for short " BWMAP ") and ONU packet map table carry out above-mentioned ID conversion, and according to ONU packet map table, carry out above-mentioned ID conversion when descending transmission.
Therefore, the technical scheme of the embodiment of the present invention can keep ONU constant, OLT and ONU interaction protocol flow process are constant, frame structure between OLT and ONU is constant, the technical scheme of the embodiment of the present invention can with existing PON operating such, can reuse existing ONU equipment as far as possible, can make OLT realize the support to large branching ratio PON system, and can make MAC layer degree of reusing high, thereby can also improve the capacity of system, and reduce the cost of system.
In embodiments of the present invention, MAC at OLT is inner, using expansion equipment identifier NEW-ONU-ID as the uniquely tagged that is linked into the ONU of PON system, using expansion transmission container identifier NEW-ALLOC-ID as the uniquely tagged of PON internal system T-CONT, using the uniquely tagged of Extended Capabilities Port identifier NEW-PORT-ID as PON internal system GEM-PORT.
Alternatively, this expansion equipment identifier NEW-ONU-ID comprises the down going channel identifier DS-PON-ID of indicating downlink passage, and the device identifier ONU-ID of indicating terminal equipment, and is unique at all ONU-ID of same down going channel; This expansion transmission container identifier NEW-ALLOC-ID comprises this transmission container identifier ALLOC-ID of this down going channel identifier DS-PON-ID and indication transmission container, and is unique at all ALLOC-ID of same down going channel; This Extended Capabilities Port identifier NEW-PORT-ID comprises this port identifiers PORT-ID of this down going channel identifier DS-PON-ID and indication port, and is unique at all PORT-ID of same down going channel.
For example, in HPON, each ONU can only receive the information of a downstream wavelength, the corresponding a part of ONU of each downstream wavelength, such as, the ONU subset that belongs to Tong Ge PON branch, wherein, different PON branches corresponds respectively to different downstream wavelength passages, and can identify by different PON-ID.Therefore, as shown in Figure 3, expansion equipment identifier NEW-ONU-ID can comprise two parts, and front portion is down going channel identifier DS-PON-ID, and rear portion is the device identifier ONU-ID that can only receive the ONU of the corresponding downstream wavelength of this DS-PON-ID.And the definition of latter part of device identifier ONU-ID and functional description meet definition and the functional description of existing standard, as ONU-ID equals 255 as broadcast ID.
In like manner, expansion transmission container identifier NEW-ALLOC-ID can comprise the transmission container identifier ALLOC-ID in the ONU subset that down going channel identifier DS-PON-ID and this DS-PON-ID are corresponding; Extended Capabilities Port identifier NEW-PORT-ID can comprise the port identifiers PORT-ID in the ONU subset that down going channel identifier DS-PON-ID and this DS-PON-ID are corresponding.
DS-PON-ID is that full 1(refers to binary system, as 0xFF) be illustrated in all downstream wavelength and broadcast.If the DS-PON-ID of NEW-ONU-ID partly refers to binary system for full 1(, as 0xFF), and ONU-ID is partly the ID of single ONU, ONU identical with described ONU-ID in all downstream wavelength is carried out to multicast; If ONU-ID is partly broadcast ID, is full 1(and refers to binary system, as 0xFF), all ONU are broadcasted.If the DS-PON-ID of NEW-ONU-ID is single downstream wavelength ID, and ONU-ID is partly broadcast ID, all ONU corresponding to this DS-PON-ID is carried out to multicast.NEW-ALLOC-ID and NEW-PORT-ID in like manner repeat no more.
In ONU-ID assigning process, the ONU-ID that OLT only need guarantee to distribute in the ONU subset of same downstream wavelength is unique, and in like manner ALLOC-ID, PORT-ID are unique in the ONU of same downstream wavelength subset.This also means, the ONU-ID in the ONU subset of different downstream wavelength is likely identical.
Should understand, the embodiment of the present invention be take Fig. 3 and is described as example, but the embodiment of the present invention is not limited to this, for example, identifier after down going channel identifier DS-PON-ID and expansion can have larger length, for example, identifier after expansion can be used to indicate any in terminal equipment, transmission container and port, and be used to indicate down going channel, and the identifier after expansion is not limited to the combination of down going channel identifier and device identifier, former transmission container identifier or port identifiers.
In S110, the upstream data that OLT device receiving terminal apparatus ONU sends, this upstream data portability has control information, and described control information can comprise the device identifier ONU-ID that indicates this terminal equipment.
In S120, alternatively, OLT can obtain the expansion transmission container identifier corresponding with this upstream data from bandwidth authorizing information; And according to the terminal equipment packet map table generating at ONU registration phase, obtain and the corresponding expansion equipment identifier of this expansion transmission container identifier.Wherein, this terminal equipment packet map table can comprise the corresponding relation between down going channel identifier, data feedback channel identifier, device identifier, transmission container identifier, port identifiers, expansion equipment identifier, expansion transmission container identifier and Extended Capabilities Port identifier.
Should be understood that in GPON, bandwidth authorizing information is handed down to ONU with the form of bandwidth mapping graph (Bandwidth Map, referred to as " BWMAP "), and the form of BWMAP and field implication have definition in ITU-TG.984.3, do not repeat them here.
In the OLT of HPON, in BWMAP, use expansion transmission container identifier to substitute transmission container identifier, the form of all the other fields and implication are still continued to use the definition of GPON standard; And in ONU, the form of BWMAP and implication are continued to use the definition of GPON standard completely.
For example, table 1 shows the ONU packet map table that ONU forms at registration phase.This ONU packet map table comprises the corresponding relation between down going channel identifier DS-PON-ID, data feedback channel identifier US-PON-ID, device identifier ONU-ID, transmission container identifier ALLOC-ID, port identifiers PORT-ID, expansion equipment identifier NEW-ONU-ID, expansion transmission container identifier NEW-ALLOC-ID and Extended Capabilities Port identifier NEW-PORT-ID.
Table 1
Should be understood that in the HPON systems such as ODSM-PON, TWDM-PON, uplink and downlink all may adopt a plurality of wavelength, before ONU reaches the standard grade, may be uncertain with the mapping relations of uplink and downlink wavelength.Therefore, in embodiments of the present invention, the mapping relations of ONU-ID, ALLOC-ID, GEM-PORT-ID and OLT transmitter and receiver can be set up by following two kinds of methods, automatically find, range finding, upstream bandwidth distribute, the routing issue of up-downgoing flow to solve ONU.
Method be OLT in the automatic discovery procedure of each downstream wavelength sequence starting ONU, same downstream wavelength ONU is a subset, OLT sets up the corresponding relation between ONU etc. and the Receiver And Transmitter of OLT when ONU responds.Another kind method be OLT in the automatic discovery procedure of all downstream wavelength parallel startings, in downstream message, add the numbering of OLT transmitter and in upstream message, send back to OLT, make OLT set up the corresponding relation between ONU and the Receiver And Transmitter of OLT.Form thus ONU packet map table as shown in table 1.
In S130, alternatively, when device identifier ONU-ID that the device identifier ONU-ID that OLT device comprises at the control section of this upstream data comprises with this expansion equipment identifier NEW-ONU-ID is identical, determine that device identifier ONU-ID and this expansion equipment identifier NEW-ONU-ID that the control section of this upstream data comprises match.
In S140, this device identifier ONU-ID that OLT comprises the control section of this upstream data replaces with this expansion equipment identifier NEW-ONU-ID.
Therefore, the method of the identifier of the conversion terminal equipment of the embodiment of the present invention, by the identifier to terminal equipment, replace, can realize the support of media access control layer to large branching ratio passive optical network, and can not change optical network unit or terminal, compatible with existing passive optical network standards, thus the capacity of system can be improved, and reduce the cost of system.
As previously mentioned, OLT device inside is carried out mark with identifier NEW-ONU-ID, NEW-ALLOC-ID and the NEW-PORT-ID after expanding to ONU, T-CONT, GEM-PORT, and ONU inside is carried out mark with former identifier ONU-ID, ALLOC-ID and PORT-ID to ONU, T-CONT, GEM-PORT.Therefore, can carry out ID conversion in OLT inside, the message passing mechanism between OLT and ONU can normally be carried out.
Therefore, as shown in Figure 4, according to the method 100 of the identifier of the conversion terminal equipment of the embodiment of the present invention, can also comprise:
S150, OLT device, before processing the data division of this upstream data, carries out the first identifier to the data division of this upstream data and replaces processing;
S160, OLT device, after processing the data division of this upstream data, carries out the second identifier to the data division of this upstream data and replaces processing.
In embodiments of the present invention, this first identifier is replaced to process and is comprised device identifier, transmission container identifier and port identifiers are replaced with respectively to corresponding expansion equipment identifier, expansion transmission container identifier and Extended Capabilities Port identifier; This second identifier is replaced to process and is comprised expansion equipment identifier, expansion transmission container identifier and Extended Capabilities Port identifier are replaced with respectively to corresponding device identifier, transmission container identifier and port identifiers.
In embodiments of the present invention, this expansion equipment identifier comprises the down going channel identifier DS-PON-ID of indicating downlink passage, and this device identifier ONU-ID of indicating terminal equipment; This expansion transmission container identifier comprises this transmission container identifier ALLOC-ID of this down going channel identifier and indication transmission container; This Extended Capabilities Port identifier comprises this port identifiers PORT-ID of this down going channel identifier and indication port.
Below in conjunction with Fig. 5, the HPON system of take based on GPON is example, to being described in detail according to the processing of the upstream data of the embodiment of the present invention.
As shown in Figure 5, according to the method 200 of the identifier of the terminal equipment in the conversion HPON system of the embodiment of the present invention, comprise:
S210, OLT device carries up gigabit passive optical network GPON Transmission Convergence (the Gigabit-capable passive optical network Transmission Convergence of upstream data in reception, referred to as " GTC ") frame, physical layer operations management maintenance (Physical Layer Operations Administration and Maintenance in processing this up GTC frame, referred to as " PLOAM ") before the data division of frame, the data division of this PLOAM frame is carried out to the first identifier and replace and process;
S220, OLT device, after processing the data division of this PLOAM frame, carries out the second identifier to the data division of this PLOAM frame and replaces processing;
S230, the up gigabit passive optical network GPON method for packing comprising for this up GTC frame (Gigabit-capable passive optical network Encapsulation Method, referred to as " GEM ") frame, OLT device replaces with this Extended Capabilities Port identifier by the port identifiers in this GEM frame;
S240, OLT device is being processed optical network unit ONU management and control interface (the Optical Network Unit Management and Control Interface of this GEM frame carrying, referred to as " OMCI ") before the data division of message, this OMCI message is carried out to the first identifier and replace and process;
S250, OLT device, after processing this OMCI message, carries out this second identifier to this OMCI message and replaces processing.
Should be understood that above-mentioned each process sequence number size and do not mean that the priority of execution sequence, the execution sequence of each process should determine with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present invention.
Particularly, at up direction, up GTC receiver module receives the up GTC frame (as shown in S110) of ONU according to the expansion transmission container identifier NEW-ALLOC-ID information of BWMAP, time started and dwell time information; Up GTC receiver module is searched expansion equipment identifier NEW-ONU-ID(corresponding with this expansion transmission container identifier NEW-ALLOC-ID in BWMAP as shown in S120 according to ONU packet map table), and the ONU-ID part of expansion equipment identifier NEW-ONU-ID is compared with the ONU-ID field in up GTC frame, if matched, the uplink that this ONU is described is (as shown in the S130) that meets the allocated bandwidth mandate of OLT, be for further processing, otherwise abandon, and produce alarm; Then, up GTC receiver module replaces to corresponding expansion equipment identifier NEW-ONU-ID(as shown in S140 by the device identifier ONU-ID of the up GTC frame header meeting).
For the control section of up GTC frame, up GTC receiver module has replaced to ONU-ID corresponding NEW-ONU-ID; The PLOAM frame comprising for the data division of up GTC frame, up GTC receiver module is given PLOAM module by this PLOAM frame and is processed, data (Data) part for PLOAM frame, if relate to ONU-ID, ALLOC-ID or PORT-ID, PLOAM module replaced to corresponding NEW-ONU-ID, NEW-ALLOC-ID or NEW-PORT-ID(as shown in S210 before processing), after handling, PLOAM module converts thereof into corresponding ONU-ID, ALLOC-ID or PORT-ID(again as shown in S220).Should be understood that the control section for up PLOAM frame can replace to corresponding NEW-ONU-ID by ONU-ID by up GTC receiver module or PLOAM module.
The DBRu(Dynamic Bandwidth Report upstream comprising for the data division of up GTC frame, up dynamic bandwidth report) field, this DBRu field comprises DBA(Dynamic Bandwidth Allocation, Dynamic Bandwidth Allocation) and CRC(Cyclic Redundancy Check, cyclic redundancy check (CRC)) field, this DBA field is the indication of customer flow demand information.Because DBRu field itself does not comprise id information, but corresponding with NEW-ALLOC-ID according to up sequential relationship, up GTC receiver module extracts NEW-ALLOC-ID and DBA to give DBA computing module and process.
