Data transmission interface or agreement.
Preferably, the step S3It is further comprising the steps of afterwards:
Configuration based on service board described in the configuration data management.I.e. heretofore described service board is parsing data
After configuration data in packet, so that it may realize the configuration management of the specific business of service board.
Preferably, the step S3It is further comprising the steps of afterwards:
The service board sends a feedback data packet to the main control unit.
Heretofore described service board can pass through the shapes such as data packet after the configuration management that success or failure realizes business
Formula informs the success or failure of main control unit configuration concrete configuration, consequently facilitating further management of the main control unit to service board.
Preferably, the data packet is UDP(User Datagram Protocol) data message.
Preferably, the UDP message message includes in Cmd ID, Session ID, Ack ID, Option ID and data
Hold.
The Cmd ID, Session ID, Ack ID, Option ID and data content are that the UDP message message of composition is each
The structure of a content, the UDP message message is the well-known technique of those skilled in the art, so being no longer described in detail here.
Preferably, the step S1Are as follows:
A TLV Number parameter is added in the main control unit of the OLT system in the data content of the UDP message message
With multiple TLV contents including the configuration data.
Wherein the TLV Number parameter is used to identify the number of TLV content in the data content, thus service board
When parsing the data content portion, the quantity of the TLV content can be known.
The TLV content contains specific configuration data, due to including Tag, Length and Value in TLV.So industry
Business disk can form a prompt judgement out specific business content configuration and management.
Preferably, the step S3Are as follows:
The service board is read based on the TLV Number parameter of the UDP message message comprising described in configuration data
TLV content.
Preferably, the step S3After further comprise the steps of:
Based on the configuration of service board described in the configuration data management, the service board sends a feedback UDP message message
To the main control unit.
The present invention provides a kind of OLT system, the OLT system includes a main control unit and one or more service boards,
Feature is that master-slave communication method as described above is used between the main control unit and the service board.
Preferably, service board is EPON(ethernet passive optical network) disk or GPON(Gigabit Passive Optical Network) disk.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get each preferable reality of the present invention
Example.
The positive effect of the present invention is that:
The configuration data of TLV format is added master-slave communication method of the invention by using the data content in message.I.e.
For one type of parameter definition of each configuration data, then added using the mode of triple mode (Type, Length, Data)
It is added in message, without providing some parameter to specific position.So that group packet mode flexibly, it is simple and be convenient for
Extension.
Detailed description of the invention
Fig. 1 is that the present invention is preferably communication flow diagram between the main control unit and service board of embodiment.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
It include a main control unit and a service board in the OLT system of the present embodiment, wherein the service board can be OLT system
Related EPON disk or GPON disk.The EPON disk and GPON disk are each responsible for the access of EPON and GPON communication data, and
Convert optical signals into ether data message and send main control unit to, while and responsible OLT system in ONU(optical node) channel
Management.
And according to the type of business of actual use or it can also need to increase service board in the OLT system of the present embodiment
Quantity.
Configuration data is filled into message by main control unit described in the present embodiment by the format of TLV, with realization group packet
Flexibly and extend.The lattice of one layer of TLV are encapsulated i.e. in the present embodiment in the data content of the UDP message packet of the main control unit group packet
Configuration data is sent UDP number of the format by configuration data for encapsulating TLV by formula by socket between main control unit and service board
It is in communication with each other according to message to realize, service board, which receives, will configure number for the format for separating TLV after the UDP message message of opposite end
According to by parsing configuration data content, to realize the configuration management of specific business.
Below by the communication process shown in Fig. 1, illustrated between the embodiment of the present invention main control unit and service board.
Step 1, the OLT system main control unit TLV Number is added in the data content of the UDP message message
Parameter and TLV content including the configuration data.
Wherein the UDP datagram text includes Cmd ID, Session ID, Ack ID, Option ID and data content.
CMD ID is order ID, and each business configuration has a unique order ID, and system can be accurate according to the ID
Identify the order.
Order ID described in the present embodiment is in BM(Board Manage, panel management) module definition, other business modules
It can quote.Following definition format can be used:
The Session ID is session id, in the present embodiment for be BM module be every order temporarily generate it is unique
Mark needs one session id of dynamic generation when BM module group packet is sent, and then passes through MSC(master-slave communication) it is sent to business
Disk need to receive response packet, according to the session id responded in packet with the session id, the BM module when service board has handled response
Confirm the state of transmitting order to lower levels.
The ACK ID of the present embodiment is response ID, which is used to carry the return value of response message, is transported under main control unit
When setting, service board is handled according to the configuration issued, is filled into the field for the result of processing, is returned to main control unit,
The case where main control unit knows configuration according to the field and result.
The field of the embodiment of the present invention Option ID is Option Field, for indicating the type of the message, defines generation
Code is as follows:
The TLV Number parameter is used to identify the number of TLV content in the data content, so that service board is solving
When analysing the data content portion, the quantity of the TLV content can be known.T field in TLV format indicates type of message, L
Field indicates that message length, V field are often used to store the content of message.
I.e. the parameter field of TLV Number described in the present embodiment is for indicating the number of TLV parameter in message, according to this
Field can be convenient the content for parsing TLV field
The TLV content contains specific configuration data, due to including Tag, Length and Value in TLV.So industry
Business disk can form a prompt judgement out specific business content configuration and management.
The code configuration of TLV content described in the present embodiment is as follows:
Step 2, the main control unit sends the data packet to the service board by socket.
Step 3, the service board is read based on the TLV Number parameter of the UDP message message comprising configuration data
The TLV content.
Step 4, the configuration based on service board described in the configuration data management, the service board send a feedback UDP number
According to message to the main control unit.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed
Protection scope of the present invention is each fallen with modification.
