ONU interrupts regular traffic and carries out the quantity of business migration, while also considering shadow of the suspend mode ONU quantity for business migration
It rings.
In step S206, such as migration and suspend mode control that following methods carry out ONU may be used：
First method migrates the ONU that enlivens hung under the ports OLT of traffic load minimum to other ports OLT, if
Not lower to hang suspend mode ONU, then the ports OLT that can control traffic load minimum enter suspend mode, if the traffic load is most
The small ports OLT also hang with down suspend mode ONU, and suspend mode ONU is waken up and is migrated to other ports OLT, then controls the business again
The ports OLT of load minimum enter suspend mode.Business migration is carried out by waking up suspend mode ONU in advance, reduces its business recovery
Time, avoid ONU it is spontaneous restart reach the standard grade, reduce influence to existing network service.
Second method migrates the ONU that enlivens hung under the ports OLT of traffic load minimum to other ports OLT, if
Not lower to hang suspend mode ONU, then the ports OLT that can control traffic load minimum enter suspend mode, if the traffic load is most
The small ports OLT also hang with down suspend mode ONU, and opening timing device wakes up suspend mode ONU as much as possible simultaneously in timing
It migrates to other ports OLT, after timer expiry, if still there is ONU not respond or do not complete business migration work, to ensure
The ports OLT can smoothly enter suspend mode in time, then abandon the processing to remaining ONU, control the OLT of traffic load minimum
Port enters suspend mode.
These do not complete the ONU of migration, since the ports OLT have been switched off, then can not receive what the ports OLT issued
Downlink data, when that can not receive downlink data in certain time, these ONU can restart authentication registration process, at this point, by
OLT system is that these ONU share out the work wavelength and the specific ports OLT, but this process actively wakes up compared to the ports OLT again
Migration is more time-consuming, and a large amount of ONU restart simultaneously after carry out authentication registration larger instantaneous bear also brought to OLT system
Lotus, therefore the present invention handles the ONU of energy saving suspend mode by actively waking up migration pattern first, is examined again after timer expiry
Consider the identifying procedure that re-registers using system itself, utmostly reduces the influence to existing network service.
