Embodiment
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Fig. 1 is the schematic flow sheet of the transmission method embodiment of data in EPON provided by the invention.Embodiment of the method shown in Fig. 1, comprising:
If step 101 adopts the cradle head control protocol address of the terminal equipment of terminal equipment and another ONU hung under ONU in the system of cradle head control agreement to repeat, then OLT is when initiating the communication with certain terminal equipment, sends and comprises the identify label of ONU corresponding to described terminal equipment and the message of cradle head control protocol address;
Wherein, because cradle head control agreement only supports that address is 8 binary addresses, 8 bit address that system therefore can recognize are as cradle head control protocol address;
Step 102, ONU are after the message receiving the identify label comprising ONU, obtain the identify label of ONU in described message, and described identify label and respective identify label are compared, if identical, then send described message according to the cradle head control protocol address in this message.
Compared with prior art single employing cradle head control protocol address marking terminal equipment, embodiment of the method provided by the invention, when the cradle head control protocol address of the terminal equipment hung under ONU in the system adopting cradle head control agreement and the terminal equipment of another ONU repeats, identify label in conjunction with ONU identifies this terminal equipment, realize the man-to-man control to the terminal equipment of cradle head control agreement identical under different ONU, the convenient dilatation to system.
Wherein, the identify label of described ONU is carried by preamble field.Certainly, can also select other fields, the field wherein selected can undefined field in message protocol, and configures all ONU and all resolve this field when receiving message.
Certainly, this ONU identify label is used to the one mark uniquely determining ONU, as long as the information of an ONU namely uniquely can be determined in multiple ONU, such as, number consecutively is carried out to the ONU in system, when numbering is as identify label, as long as ONU and OLT knows which ONU is which is numbered.OLT knows the identify label of each ONU.
The present invention is simple for realizing, and adopts the identify label of ONU to be logical links mark (LogicalLinkIdentifier, LLID).
Wherein, described OLT obtains the corresponding relation that described system is the identify label of the device address distributed of each terminal equipment and ONU in the following way, comprising:
ONU when registering to OLT, in the device address of the terminal equipment that extended operation, the field administered and maintained in OAM agreement are hung under sending this ONU;
OLT, by receiving the content that in expansion OAM agreement, field is carried, obtains the corresponding relation that described system is the device address of each terminal equipment distribution and the identify label of ONU.
A kind of management agreement in OAM agreement EPON system, the administrative message that can maintain between OLT and ONU is mutual, expansion OAM agreement is the expansions of telecom operators to this standard, different operators definition is slightly different, there is a little self-defining field in this agreement, these self-defining fields that the present invention utilizes just have accomplished cradle head control protocol address to pass to OLT, certainly simultaneously, in practical application, also other cradle head control property parameters can be sent to OLT.
Wherein, above-mentionedly illustrated that cradle head control agreement can only identify 8 binary addresses, therefore in described system, the cradle head control protocol address of at least two terminal equipments repeats to comprise:
System be the device address distributed of terminal equipment more than 8 time, the device address more than 8 can be that the device address of the terminal equipment of 8 is identical by the part of system identification and cradle head control protocol address.
Specifically, if the device address of terminal equipment is 8, then cradle head control protocol address is the device address of this terminal equipment, if there is the device address of more than 9 in system, this will exceed the scope of The Cloud Terrace agreement support, therefore, the cradle head control protocol address that system can identify is latter 8, therefore device address is just in time that the cradle head control protocol address of the terminal equipment of 8 is identical with device address more than the cradle head control protocol address of the terminal equipment of 8, such as, when identification equipment address is 10.00.00.00.00, the cradle head control protocol address obtained is 00.00.00.00, identical with the cradle head control protocol address of already present terminal equipment.
It should be noted that, the number of the terminal equipment hung under an ONU can be one or more, when quantity is multiple, the cradle head control protocol address that can configure the multiple terminal equipments under same ONU does not repeat mutually, thus ensures to realize man-to-man management to the multiple terminal equipments under same ONU.
Be described with an embody rule example below:
Fig. 2 is the schematic diagram of the management system of the cradle head control agreement based on EPON technology provided by the invention.In system shown in Figure 2, management system downgoing control signal based on the cradle head control agreement of EPON technology adopts RS485 data after ONU process, to pass to The Cloud Terrace by broadcast transmission mostly, and cradle head control protocol address is 8 bits, this just there will be a problem: when the camera of cradle head control in system is more than 256, the cradle head control protocol address of the terminal equipment under different ONU repeats, how to distinguish these terminal device address?
Be described below by two embodiments:
Embodiment one
System is the situation that 1 ONU controls 1 cradle head control terminal equipment, when described system adds new terminal equipment, the device address of the terminal equipment newly added, can human configuration be passed through, certainly, can also at OLT after having detected that new equipment adds, for this terminal equipment newly added produces a device address, and the ONU of lower this terminal equipment of extension is handed down to by the field in expansion OAM agreement, certainly, the minimum requirements of configuration is that the device address of the terminal equipment under same ONU is different.
Certainly, if adopt the device address of the former configurating terminal device, OLT is the device address cannot learning terminal equipment, therefore when ONU initiates registration to OLT, inform the device address of its lower terminal equipment hung of OLT, wherein the address of this terminal equipment can be sent by the field in expansion OAM agreement.
To how realizing OLT, how unique identification terminal equipment is described below, comprises step a ~ d, wherein:
Step a, acquisition system are the corresponding relation of the device address of each terminal equipment distribution and the identify label of ONU;
Wherein, ONU when registering to OLT, in the device address of the terminal equipment that extended operation, the field administered and maintained in OAM agreement are hung under sending this ONU; OLT, by receiving the content that in expansion OAM agreement, field is carried, obtains the corresponding relation that described system is the device address of each terminal equipment distribution and the identify label of ONU.
Step b, preserve the corresponding relation of the device address of each terminal equipment and the identify label of ONU;
Step c, behind the device address obtaining user's input, according to the device address of user's input, in described corresponding relation, the identify label of the ONU corresponding to device address of inquiring user input;
Wherein, the device address of user's input can obtain in the following way, comprise: the Serial No. be made up of numeral 0 ~ 9 receiving outside input, according to the corresponding relation of the device address of Serial No. and terminal equipment, determine the device address that described user inputs, such as, the binary expression arranging the Serial No. of user's input is the device address of the terminal equipment that will control, if user inputs 0, then represent that the device address of terminal equipment that will control is 00.00.00.00, if the Serial No. of input is 256, then represent that the device address of control is 1.00.00.00.00.
If steps d inquires, then device address user inputted rear 8 as cradle head control protocol address, send to comprise and inquire about the identify label of ONU that obtains and the message of cradle head control protocol address.
This shows, when cradle head control agreement is more than 8, the terminal equipment that under different ONU, cradle head control protocol address repeats uniquely recognizes a terminal equipment by the identity information of ONU, realizes man-to-man control.
Embodiment two
System is the situation that 1 ONU controls 1 cradle head control terminal equipment, conveniently user selects the terminal equipment that will control by numeric keypad, the device address of the terminal equipment newly added, two of embodiment one kinds of modes can certainly be adopted to be configured, when the device address of this terminal equipment newly added is not only different from the device address of terminal equipment existing under same ONU, also there is following features:
