Detailed description of the invention
Embodiment 1, the present embodiment is a kind of intelligent method for releasing based on EPON band, comprises the following steps:
Step 1, by EPON manager, ONT Optical Network Terminal is initialized.
Step 2, by EPON manager, create thread and adopt the mode of poll to check the data link output queue that will monitor, if queue is sky to be represented countlessly according to output, indicate without flow, otherwise have flow.
If step 3, within the time of setting, detects that up direction has flow, initiate linking request to opposite end, network connection state is set for connecting; If within the time of setting, detect that up direction does not have flow, hang up the link of up direction, network state is set for hanging up.
Here network connection state variable is a temporary variable, exists in internal memory, and after power-off, it can be cleared, and after powering on and restarting, system can be opened up again an internal memory for it and be stored it.
Concrete steps are: if within the time of setting, detect that up direction has flow, ONU sends a pppoe linking request message, if ONU receives the response message of server, network connection state is set for connecting; If within the time of setting, detect that up direction does not have flow, hang up the link of up direction, network state is set for hanging up;
The flow of step 4, continuation up direction to ONT Optical Network Terminal by EPON manager is monitored;
If step 5, within the time of setting, detects that up direction has flow, if now network connection state is for connecting, turn to step 4, if now network connection state is for hanging up, initiate linking request to opposite end, and network connection state is set for connecting, turn to step 4;
If within the time of setting, detect that up direction does not have flow, if now network connection state is for connecting, hang up the link of up direction, network state is set for hanging up, turn to step 4, if now network connection state, for hanging up, turns to step 4.
Here setting-up time supports and holds according to reality, and general half an hour is proper, in time that also can be shorter.

After the first initializes, the flow of the up direction by EPON manager to ONT Optical Network Terminal is monitored;
Now, if within the time of setting, detect that up direction has flow, initiate linking request to opposite end, network connection state is set for connecting; If within the time of setting, detect that up direction does not have flow, hang up the link of up direction, network state is set for hanging up.
In passive light network terminal is normally worked kind, also by EPON manager, the flow of the up direction to ONT Optical Network Terminal was monitored.
Now, there are following two kinds of situations:
If within the time of setting, detect that up direction has flow, if now network connection state is for connecting, continue monitoring, if now network connection state is for hanging up, initiate linking request to opposite end, and network connection state is set for connecting, continue monitoring.
If within the time of setting, detect that up direction does not have flow, if now network connection state is for connecting, hang up the link of up direction, network state is set for hanging up, continue monitoring, if now network connection state is for hanging up, continue monitoring.
The master and slave flow chart of the present embodiment while specifically implementing as shown in Figure 2,3
Based on EPON broad band intelligent method for releasing, said method is that the real-time supervisory user data message of passive light network terminal (ONU) has will send by wide area network time, can be automatically and the other side initiate linking request and set up communication port, idle link is implemented automatically to hang up processing, abandon the data message that WAN connects input direction. Detailed process is as follows.
Host process handling process: as Fig. 2
Step1: by EPON manager, start the broad band intelligent hypervisor in single user optical network unit MCU, initialize and load relevant configured parameter, such as idle timeout, flow-control etc. are set;
Step2: circulation receives the message that monitoring WAN connection traffic process is sent;
Step3: if receive the disconnect message that monitoring WAN connection traffic process is sent, host process is hung up the link connection that this WAN connects, and abandons the data message that this WAN connects input direction;
Setp4: if receive the connect message that monitoring WAN connection traffic process is sent, host process is initiated to set up communication port with opposite end communication linkage request.
Monitoring WAN connection traffic process handling process: as Fig. 3
Step1: scan round monitoring WAN connects the flow of outbound course, starts hardware timer simultaneously, if reset hardware timer when WAN connection outbound course has data flow within the time of setting;
Step2: the connection status that WAN connects within the time of setting is connect state, if WAN connects outbound course without flow, sends a disconnect message to host process;
Setp3: sometime, if detected when user data message will connect transmission by this WAN, send a connect message to host process, the hardware timer of simultaneously resetting after disconnection WAN connects.
According to above-mentioned method for designing, when understanding the link of automatic hanging connection breaking free time and have user data message to send by wide area network, passive light network terminal (ONU) sets up communication port, effectively utilize network broadband resource.
