At present, the method that is commonly used to discern BBU is: the identification label manually is set, such as, one toggle switch is set respectively among each BBU, manually toggle switch is allocated to different positions is provided with different values, the CPU of each BBU reads the value that toggle switch is provided with by I/O (I/O) interface, and the identification label that will be worth as self is stored in this locality.Each BBU in the system can send the identification label of oneself by broadcast to other BBU, each BBU can be stored in this locality with the identification label of other BBU of receiving by broadcast, like this, among any one BBU in system, all there is the identification label of self and other all BBU.
For the method for above-mentioned identification BBU,, can cause system works unusual because of the conflict of identification label, even make whole system in paralyzed state if because the manually error when toggle switch is set causes the identification label of two BBU identical.So, in whole system, corresponding different BBU, the identification label of setting should be unique.
For the identification label that guarantees each BBU is unique, need to increase complicated collision detection mechanism in whole system.When BBU broadcasts the identification label of self to whole system, there is identical identification label, can sends collision alert to network management center if collision detection mechanism detects.After alarm is received by network management center,, again toggle switch is pushed the work that recovery system is come in the correct position of being planned by systematic unity by sending the staff to the scene.
In sum, prior art is provided with the method that the identification label is discerned different B BU by toggle switch, need manually be provided with on the one hand, be subjected to bigger human factor influence, on the other hand, the identification label collision failure that causes for fear of the error that causes owing to human factor takes place, need to increase complicated collision detection mechanism, increase the complexity of system, reduced the stability of system, and to discerning the processing inconvenience of label collision failure.

Embodiment
Core concept of the present invention is: adopt the globally unique MAC Address of BBU to identify BBU as the identification label, simply and reliably different BBU is discerned, and effectively avoided the generation of identification label collision failure.
For each BBU, all can a MAC Address be set before dispatching from the factory and be stored in the hardware of BBU by producer, set MAC Address is a globally unique value.Generally, MAC Address is stored in the erasable read-only memory (EPROM), in BBU uses, can be by reading the MAC Address that EPROM obtains BBU.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 1 is the flow chart that the present invention discerns BBU, in conjunction with the structural representation of BBU employing chain networking in Fig. 2 embodiment of the invention, supposes to send data message from BBU0 to BBU2, and promptly BBU0 is source BBU, and BBU2 is purpose BBU.And the identification label of hypothesis BBU0 is that the identification label of MAC0 address, BBU1 is that the identification label of MAC 1 address, BBU2 is that the identification label of MAC2 address, BBU3 is the MAC3 address, and the specific implementation that the present invention discerns BBU may further comprise the steps:
Step 100: source BBU obtains source MAC and target MAC (Media Access Control) address.
For each BBU in the BBU chain networking system shown in Figure 2, when BBU starts, the self MAC address can be taken out from EPROM, store in the local data memory (RAM) as source MAC; In addition, by broadcast, the MAC Address of other BBU in the group network system under the BBU reception self, and the different MAC Address that will receive are stored among the local RAM as different destination addresses.
Specifically, in the RAM of BBU0, the source MAC of storage is the MAC0 address, and target MAC (Media Access Control) address then comprises MAC1 address, MAC2 address and MAC3 address; In the RAM of BBU1, the source MAC of storage is the MAC1 address, and target MAC (Media Access Control) address then comprises MAC0 address, MAC1 address and MAC3 address; In the RAM of BBU2, the source MAC of storage is the MAC2 address, and target MAC (Media Access Control) address then comprises MAC0 address, MAC1 address and MAC3 address; In the RAM of BBU3, the source MAC of storage is the MAC3 address, and target MAC (Media Access Control) address then comprises MAC0 address, MAC 1 address and MAC2 address.
In the present embodiment, suppose to send data message from BBU0 to BBU2, so in this step, the method that source BBU obtains source MAC and target MAC (Media Access Control) address is: BBU0 reads source MAC from RAM be that MAC0 address and target MAC (Media Access Control) address are the MAC2 address.Also can realize like this: BBU0 reads source MAC from EPROM, i.e. the MAC0 address; From RAM, read target MAC (Media Access Control) address, i.e. the MAC2 address.
Step 101: source BBU is carried at source MAC and the target MAC (Media Access Control) address that obtains in the Frame that will send, and sends this Frame.
A kind of data frame format schematic diagram that the present invention of being shown in Figure 3 adopts, as shown in Figure 3, in the data frame format that sends, comprise the source MAC field of storing source MAC, the target MAC (Media Access Control) address field of storage purpose MAC Address, the data message field of storing data information and the parity fields of storage parity position.
In this step, the MAC0 address of reading is stored in the source MAC field of Frame, the MAC2 address of reading is stored in the target MAC (Media Access Control) address field of Frame, and data message and parity check bit be stored in respectively in data message field and the parity fields, send this Frame then.
Step 102～step 104: receive BBU and resolve the Frame that receives, and whether the target MAC (Media Access Control) address that relatively carries in this Frame is consistent with the self MAC address, if it is consistent, then identification is certainly as purpose BBU, accept this Frame, and identify source BBU according to the source MAC that carries in this Frame; Otherwise, identify source BBU according to the source MAC that carries in this Frame, and to discern self not purpose BBU, the Frame that receives is transmitted to next stage receives BBU, return this step afterwards and rejudge.
In fact, only, receive BBU, identify self according to target MAC (Media Access Control) address and whether get final product for purpose BBU as long as which BBU identifies source BBU according to the source MAC that carries in the receiving Frame is at identification BBU.Further, receiving BBU and can whether accept or transmit the current Frame of receiving for purpose BBU decides according to self, is optional to the processing of Frame.
In the BBU networking, data are to send from sending BBU, and then the order of one-level one-level transmits, till purpose BBU receives.
In the present embodiment, sending BBU is BBU0, receives BBU and comprises BBU1, BBU2 and BBU3, and wherein BBU2 is purpose BBU.
In this step, Frame from the BBU0 transmission, at first receive by BBU1, BBU1 resolves the Frame that receives, by comparing, the MAC3 address and self MAC 1 address of carrying in this Frame are inconsistent, and then identifying source BBU according to the source MAC that carries in this Frame is BBU0, and identifying self is not purpose BBU, and BBU1 is forwarded to next stage BBU2 with the Frame that receives; BBU2 is by relatively, and the MAC2 address of carrying in this Frame is consistent with self MAC 2 addresses, and then identifying self is purpose BBU, and BBU2 accepts this Frame, and to identify source BBU according to the source MAC that carries in this Frame be BBU0.
From the method for the invention described above identification BBU as can be seen, because MAC Address is globally unique, adopt MAC Address to identify different B BU as the identification label, simply and reliably different BBU is discerned, because the particularity of MAC Address, the probability that identical MAC Address occurs is extremely low, so also just avoided the generation of identification label collision failure, between BBU by being carried at source MAC and the target MAC (Media Access Control) address in the Frame, carry out the data transmission reliably, do not worried Frame to be sent to the problem of purpose BBU.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
