Embodiment
For flexibility and the ease for maintenance that rises to the slave unit assign logical addresses, the embodiment of the invention provides a kind of method and system of slave unit assign logical addresses that are, below specifies through some embodiment.
101, slave unit sends the message of request logical address to corresponding buffer region.
102, main equipment is known the logical address of this slave unit with the annexation between the buffer zone address contrast master-slave equipment that receives above-mentioned message.
103, the logical address that will know of main equipment sends it back this slave unit.
201, upward the annexation between the master-slave equipment is configured at main equipment or OMC (Operation Maintenance Center, operation maintenance center); A port of a main equipment can be hung a plurality of slave units, is that example describes with 4 slave units of a port cascade below.
202, (illustrating) as shown in table 1, the annexation between the master-slave equipment comprises: the corresponding relation between the HOP value of main equipment port numbers, each slave unit, the logical address three of each slave unit.The logical address of the slave units at different levels under the same port can be can be interval skip also continuously, depends on the configuration of OMC, and OMC does not have the slave unit of configuration to represent with 0xff;
Table 1
203, main equipment is encapsulated in the HOP value of slave units at different levels in the control messages (ControlMessage) of port, and the HOP value that the first order slave unit that links to each other is corresponding marks; First order slave unit gets access to HOP value at the corresponding levels according to mark, and the HOP value that the next stage slave unit is corresponding marks; By that analogy.
204, after slave unit obtained each self-corresponding HOP value, in power up, initiatively the logical address of configuration was obtained in the foundation of the transport layer link between initiation and the main equipment from main equipment.
205, need get access to self signaling data stream time slot corresponding (multiplex/demultiplex rule) after slave unit powers on, the slave unit on same link takies different time slots, like this signaling flow independence that on the bottom link, just is isolated from each other.
206, the logic of slave unit needs to judge whether configuration information changes when the multiplex/demultiplex control messages (Control Message) of period treatment main equipment broadcasting.If get access to new multiplex/demultiplex rule, then need reconfigure slave unit.
207, the idiographic flow of message transmission does, main equipment is provided with different transmitting-receiving buffering areas for 4 grades of slave units of each port, and is as shown in Figure 3; When slave unit sends signaling message, select corresponding sending buffer address according to the logical address of purpose slave unit; When receiving the slave unit signaling message, can look into the logical address that configuration obtains slave unit, carry out subsequent processes again from the address that receives buffering area.
Slave unit master control process module 301: after the system of slave unit control master control process powers on, through initializtion protocol to the master devices request logical address.Because main equipment is provided with different transmitting-receiving buffering areas for the slave units at different levels of each port in advance; And for the slave units at different levels of each port have disposed the transmitting-receiving buffer zone address, so when main equipment receives the logical address request message of slave unit, can learn it is that which rank of slave unit is sent through the address that receives buffering area; Like 2 grades of slave units of 0 port; Configuration in the question blank 1 then can be known the logical address of this slave unit, constructs the logical address of slave unit; Send it back slave unit through initializtion protocol again, accomplish the handling process that the slave unit logical address is obtained.After slave unit master control process gets access to logical address, begin to send out the message that powers on to the basic process of each registration.
OMC data configuration module 302: the annexation in operation maintenance center (OMC) configuration interface between HRP-configured master device and the slave unit port.The situation of corresponding subordinate devices cascaded can be hung a plurality of slave units under the main equipment port.Through the OMC configuration interface, can increase slave unit, deletion slave unit, and each item configuration data of revising slave unit.
Main equipment link multiplex/demultiplex module 303: according to the master-slave equipment annexation that disposes in the OMC configuration interface; Generate the link multiplex/demultiplex rule of slave unit, and be encapsulated in the control messages (Control Message) of port to all slave unit broadcasting.
The flow process that each slave unit on the link (for example altogether 4 grades) obtains configuration is following: the main equipment logic constantly sends to the configuration frame of each slave unit that this link is hung up and down on the link, and the configuration frame comprises following several field:
HOP-ID: identifying this slave unit is which level of place optical fiber, 0～3.
MY-HOP: the slave unit that this field indication receives, it is at the corresponding levels whether this message belongs to.Slave unit can receive itself with and a plurality of configuration frames at different levels in downstream.It only gets a wherein minimum configuration frame of HOP-ID, disposes as the corresponding levels; The MY-HOP field of this frame is 1.Other configuration frame is forwarded to the downstream slave unit.
When main equipment is configured, put 1 only for the MY-HOP field of the configuration frame of the 1st grade of slave unit on the optical fiber, other slave units put 0.These configuration frames comprise 4 situation of HOP-ID from [0～3].
The HOP-ID of all configuration frames the insides that the inspection of the 1st grade of slave unit is received can receive all frames of HOP-ID==0～3; Wherein 0 minimum and MY-HOP field are 1; Therefore thinking that the corresponding levels are the upper levels, is the configuration as the corresponding levels of 0 frame with HOP-ID.Afterwards, the frame of HOP-ID==1～3 is forwarded to downstream, and the MY-HOP field of the frame of HOP-ID=1 is put 1.Can receive the frame of HOP-ID=1～3 for the 2nd grade, it will think that the frame of HOP-ID=1 is configuration at the corresponding levels.All the other are at different levels and the like, can both obtain proper configuration.
Slave unit communication link process module 304: after the communication link process (CLP) of slave unit is received the message that powers on, initiatively initiate and main equipment between the foundation of transport layer link, for other processes provide and main equipment between the support of reliable transmission.Configuration information below the CLP process of slave unit need write down in link setup:
The logical address of main equipment
The logical address of slave unit
The port numbers that connects the place main equipment
The progression of slave unit in link
4 above-mentioned configuration set information all need check whether change in the CLP process after the each and main equipment link re-establishment, and any configuration set information slave unit that changed all will reset Configuration Data.The logic of slave unit will judge also whether above-mentioned 4 configuration set information change when the multiplex/demultiplex control messages (Control Message) of period treatment main equipment broadcasting, if get access to new multiplex/demultiplex rule, also will reset Configuration Data.
Annexation between the 401:OMC data configuration module 302 configuration master-slave equipments is after configuration is accomplished, through data sync, with the slave unit annexation notice main equipment of each port of main equipment that disposes.
402: slave unit communication link process module 304 after the communication link process (CLP) of slave unit is received the message that powers on, initiatively initiate and main equipment between the foundation of transport layer link, for other processes provide and main equipment between the support of reliable transmission.
403: main equipment link multiplex/demultiplex 303 cycles of module are gone up the multiplexing rule to each node of slave unit broadcasting in control messages (Control Message).The rule of multiplex/demultiplex is that in first order slave unit first signalling time slot of use, second level slave unit uses second signalling time slot, by that analogy.
404: after the system of slave unit control master control process powers on, through initializtion protocol to the master devices request logical address.
405: because main equipment is provided with different transmitting-receiving buffering areas for the slave units at different levels of each port in advance; And for the slave units at different levels of each port have disposed the transmitting-receiving buffer zone address, so when slave unit master control process module 301 receives the logical address request message of slave unit, can learn it is that which rank of slave unit is sent through the address that receives buffering area; 1 grade of slave unit like 0 port; Configuration in the question blank 1 then can be known the logical address of this slave unit, constructs the logical address of this slave unit; Send it back slave unit through initializtion protocol again, accomplish the handling process that the slave unit logical address is obtained.
More than be preferred embodiment of the present invention, can not be interpreted as restriction claim of the present invention.Under the prerequisite that does not break away from basic principle of the present invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with accompanying claims.
