Example Embodiment
[0044] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and drawings.
[0045] In the present invention, when the OLT transmits the upgrade software to the ONU, a downstream message based on the 802.3ah standard is set, and several parts of the upgraded software are respectively encapsulated in the set downstream message based on the 802.3ah standard for transmission. Because the set downstream messages based on the 802.3ah standard can be set by the OLT according to the current EPON situation, the speed of upgrade can be increased; because the set downstream messages based on the 802.3ah standard can be sent to multiple ONUs by broadcasting , So you can support batch upgrades.
[0046] After the OLT sends all the parts of the upgraded software to the ONU through the set downstream messages, the OLT can also set a notification...
