Detailed description of the invention
Fig. 1 is the flow diagram of the ONU adaptive method for switching of PON network in the present embodiment.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described further.
As shown in Figure 1, the present embodiment provides a kind of ONU adaptive method for switching of PON network, for different in switching
When PON network route, ONU equipment can automatically detect and modify automatically inherent parameters, to be switched to corresponding operating mode,
Realize adaptive switching.
The above method mainly comprises the steps that
S1: the current PON mode of ONU is obtained；
S2: configuration error counter is simultaneously initialized as 0；
S3: whether detection fiber is inserted into；
S4: if detecting, optical fiber is not inserted into, and error counter is reset to 0；
S5: if detecting, optical fiber has been inserted into, and whether the current value for the counter that judges incorrectly is greater than predetermined value；
S6: if the current value of error counter is greater than predetermined value, switch PON mode and restarting equipment.
The ONU equipment that the present embodiment uses have GPON and EPON double working modes, can adapt to respectively GPON network and
EPON network.
After ONU equipment booting, monitoring process starts automatically, so as to the whether normal incoming fiber optic of real-time monitoring ONU equipment,
And whether the current network of detecting is normal.
Above-mentioned error counter often detects primary network event for detecting at regular intervals to current network
Barrier, then counter adds 1.After equipment is restarted, error counter is initialized to 0.
In the present embodiment, whether detection fiber has been inserted into ONU equipment first, if not having, is considered as network failure, will
Error counter resets to 0, and return step S3 is continued to test.
If detecting, optical fiber has been inserted into ONU equipment, continues to detect whether network has other failures, if detecting still
There are failures, then counter values continue growing, until its current value is greater than predetermined value.
When the numerical value of above-mentioned counter is greater than predetermined value, it is believed that after multiple network joins again, network there are still failure,
It is can determine that at this time as the operating mode of current ONU equipment and current network mode mismatch, and therefore, ONU automatically switches PON
Mode (operating mode), and restarting equipment comes into force.
If error counter does not detect more network failures, i.e. current value is not more than predetermined value always, not
It is normal for representing current network, at this point, the present embodiment increases following steps:
S7: if the current value of the error counter is not more than predetermined value, continue the state for monitoring current PON mode
It is whether normal.
Whether the state for detecting current PON mode can normally be realized by the following method:
If current PON mode is GPON network mode, following methods are used:
S711: whether detection GPON state is O1 state；
S712: if so, error counter is added 1.
If current PON mode is EPON network mode, following methods are used:
S721: detect whether the network packet received is increasing；
S722: if it is not, error counter is then added 1.
In above-mentioned steps, since current PON mode may be GPON or EPON mode, and the inspection to GPON and EPON mode
Survey method is different.
For GPON mode, usually there are multiple states, and O1 is abnormal condition, O2~O7 is normal condition,
Therefore, as long as the state of detection ONU equipment is that O1 may know that current network is abnormal condition.At this time, it may be necessary to further detect
It surveys.
For EPON mode, can most simple effective method be to receive detection network packet, if ONU equipment is received
To network packet increasing, show that current network is normal, at this point, can be by counter clear 0, and detect again network-like
State.
To avoid accidentally surveying, the present embodiment sets a predetermined value to the errors number of error counter, which is preferably 4
~6 times.When errors number reaches this value, it can just be determined as that the operating mode of current network mode and ONU equipment mismatches,
Need to switch the operating mode of ONU.
After detecting network failure, error counter adds 1, leads to error counter mistake to avoid the occurrence of network delay
It counts, the present embodiment also increases following steps:
S8: make the ONU suspend mode predetermined time.
Step S8 is located at after step S2, before step S3.It should be noted that the ONU suspend mode refers to ONU's
The suspend mode of monitoring process is not necessarily referring to the Network Process Unit suspend mode of ONU.
In the present embodiment, after counter initialization after perhaps counter adds 1 or after counter is reset as 0, make ONU
Step S8 is gone to, monitoring process sleep step is executed, helps more accurately to detect network state, reduces false detection rate.
The length of time of ONU suspend mode can be freely arranged, but be advisable with 2-3 seconds.
By above-mentioned setting, ONU can detect the network mode that local side uses automatically, so as to when network mode mismatches
The operating mode that itself can be switched in time can be adapted to current network, realize adaptive network connection.
In conclusion whether the present invention is inserted by detection fiber and whether the error counter of ONU is greater than predetermined value
Judge whether current PON mode matches current network mode, if being judged as mismatch, automatically switches PON mode to adapt to
Current network mode, to be answered by adjusting the PON mode of ONU itself to achieve the effect that oneself.The present invention supports GPON, EPON
Double mode adaptively switches, the network mode used by detecting local side automatically, and modifies inherent parameters automatically, and implementation pattern is cut
It changes, so that user is not needed replacement ONU when switching route or is upgraded software, the network upgrade and business for greatly facilitating user are opened up
Exhibition, also reduces the use cost of user.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
