Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
The upgrade method of ONU in a kind of EPON of the present invention, be applied in the OLT device of EPON, first, when ONU carry out upgrading need Activate or Commit time, because Activate order is that the mirror image programming will upgraded based on ONU sends in flash, and Commit order is sent in after ONU completes and restart, so the time confidential upgrade status according to ONU starting timer is specifically determined, namely according to the upgrade status of ONU, OLT sends a command to ONU; Upgrade status as ONU is programming when completing, and OLT just sends Activate order to ONU, and starts Activate timer, and if ONU state has been restarted time, OLT then sends Commit order to ONU, and starts Commit timer; Wherein, by a task of timer, to be used for inquiring about the upgrade status of ONU, and then send Activate or Commit order, and only start corresponding timer when the first time of this subcommand action sends and orders.
Secondly, after order is sent completely, OLT judges whether in the time slot of predetermined Retransmission timeout, to receive ONU about the response receiving order, if OLT receives response, then illustrates that command action completes, and continues to perform next action; If OLT does not receive response in the time slot of predetermined Retransmission timeout, OLT then judges whether that the number of times of continuous retransmission order is at the appointed time being less than or equal to the number of retransmissions of regulation further, if the number of times retransmitted is less than or equal to the number of retransmissions of this regulation, OLT resends with order identical before to ONU, and repeats the step that above-mentioned judgement receives response; If the number of times retransmitted is greater than the number of retransmissions of this regulation, then illustrate that command action does not complete, and disconnects, and error message is reported webmaster to carry out analyzing and processing.
Due to, Activate order allows be restarted by the ONU that upgrade image programming completes, and Commit order allows the active and standby memory block of ONU exchange, and the real-time of these two processes is not high, even can due to different ONU, different upgrade images makes reboot time and active and standby memory block reciprocal time also be not quite similar.If the stipulated time of the time slot of predetermined Retransmission timeout and continuous retransmission order is too short, order in the time slot of setting is easily caused to transmit successfully and the situation of response cannot be received, if the stipulated time of the time slot of predetermined Retransmission timeout and continuous retransmission order is long, the efficiency of escalation process can be made too low.So the time slot of predetermined Retransmission timeout and the stipulated time of continuous retransmission order will arrange different time slots and stipulated time according to different upgrade images, and this time slot and stipulated time are all directly proportional to the size of upgrade image.
Further, the stipulated number of continuous retransmission order sets according to the upgrade requirement of ONU.
