Property configures.Two above step 110 and 120 establishes mapping relations between LLID and class of service under the configuration of OLT,
It finally realizes ONU class of service is mapped on corresponding LLID；
130, downlink data frame is sent, downlink data frame includes the logic chain for the logical links for receiving the downlink data frame
Line accords with and the service identification of the downlink data frame, so that the corresponding logical links of corresponding ONU is according to logical links
Identifier receives the downlink data frame, and the downlink data frame is put into corresponding uplink and downlink queue according to service identification；Its
In, service identification is used to indicate the class of service of corresponding data frame；
What this step substantially illustrated, when OLT sends out the multiple business downlink data frame of point-to-point to ONU, OLT needs
The destination LLID of data frame is analyzed, the LLID in data frame is the LLID corresponding to the destination ONU of the business；ONU only connects
The data frame for the LLID for belonging to own is received, and downlink data frame is classified, i.e., according to the service identification of downlink data frame
Symbol, is buffered in corresponding queue, these queues have been allocated to LAN mouthfuls corresponding, the wherein mapping of uplink and downlink queue LLID
Relational graph is as shown in Figure 8；
140, uplink data frames are received, uplink data frames include the logical links for the logical links for sending the uplink data frames
The service identification of identifier and the uplink data frames；Wherein, uplink data frames according to its service identification from corresponding interchanger
Port outflow, and flow into the LAN mouths of the port of corresponding interchanger connection so that corresponding ONU is according to the upstream data
The uplink data frames are put into corresponding uplink and downlink queue by the service identification of frame, and are put into according to the uplink data frames upper
Down queue determines the logical link identifier included by the uplink data frames；
What this step substantially illustrated, when ONU sends the uplink data frames of point-to-point to OLT, ONU need to only be analyzed and be come from
The service feature of the data frame of port, the LLID in data frame are the corresponding LLID of source ONU.
In the present embodiment step 120, as shown in fig. 7, identifying procedure is specially：
The ONU for having M-LLID abilities has multiple MAC Address and corresponding multiple LLID values.It is as same first
The ONU of a S-LLID equally carries out the discovery registration process of MPCP, is registered with Base MAC (MAC 0), LLID is
Base LLID (i.e. first LLID).MPCP, standard and extension OAM find all after the completion of, OLT can inquire the ONU
The attributes such as ONU SN, FirmwareVer, Chipset ID and ONU Capability.
ONU after being configured to more LLID, successively initiate LLID-1~LLID- (NLLID-1) MPCP find registration process,
The LLID registrations of all MAC are completed in the OAM of standard and the OAM discovery procedures of extension one by one.OLT need not be to this NLLID-1
LLID, which carries out the inquiry of ONU essential informations and ability discovery, (need not inquire ONU SN, FirmwareVer, Chipset of ONU
4 attributes such as ID and ONU Capabilities-2), and only need to configure its DBA parameter, agitation function, such as
Fruit EPON system is configured to single LLID patterns, then OLT does not carry out ONU the relevant treatment of any more LLID and (do not send
AcMultiLLIDAdminControl operation informations).
The ONU feasibilities that can simulate multiple ONU are illustrated below.
In EPON system, the control between OLT and ONU uses Multi-point Control Protocol (Multi-Point Control
Protocol, MPCP) in REPORT and GATE control messages make requests on and send in pon mandate.REGISTER message
For to distribute LLID by the ONU for registering verification, it is logical links to receive GATE message and feed back the entity of REPORT message,
And it is indicated with logical link identifier (Logical Link Identifier, LLID).LLID is that EPON is used based on frame
Emulation sub-layer come the method for establishing the link of OLT to ONU, traditional point-to-point emulation generalized reference model is as shown in Figure 5.
As shown in fig. 6, emulation sub-layer uses the lead code of 8 bytes to carry emulation sub-layer identification label, wherein LLID
Two bytes are occupied, it indicates that the label of U/M and 15 bit forms by the pattern of 1 bit, and 15 bit LLID have 30,000
The capacity of a LLID, so making to become possibility to the multiple LLID of same ONU distribution.
In MAC layer, an ONU supports a LLID.When upper layer uses, ONU can be whole from optical link by one
It holds the data of the LLID of (OLT) to be sent into the N number of different queue of itself to be handled.And with the rapid development of IT technology, industry
Service type is on the increase, and supports the ONU of list LLID that cannot distinguish a large amount of emerging service type well and therefore be
So that ONU is supported more types of service, each ONU expanded to and supports 8 LLID, i.e. in ONU each queue correspond to one
LLID, from supporting the OLT of more LLID to send these LLID to ONU simultaneously.
By to the same ONU multiple LLID of distribution, simulating, multiple ONU are registered the present embodiment, certification and data frame pass
It is defeated, management and flow control of the test OLT to high-volume ONU.OLT pairs can be completed using tens times ONU fewer than traditional test
The service bearer aptitude tests of large batch of ONT reduce test environment input, management cost.
In one embodiment, optical line terminal bearing capacity test method is on the basis of the method for one embodiment
On, further include following steps：
