Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
The present invention is intended to through the negotiation between OLT and the ONU, confirms whether ONU supports the concrete energy saver mode information of energy saver mode and/or support.Based on this, the negotiation control method of a kind of energy saver mode provided by the present invention is as shown in Figure 2, mainly may further comprise the steps:
In the practical application, ONU can initiatively send to OLT with the energy saver mode of self supporting; Perhaps OLT is to the energy saver mode of the current support of this ONU of ONU acquisition request, and ONU sends to OLT according to the request of OLT with the energy saver mode of self current support.
Need to prove; For ethernet passive optical network (EPON; Ethernet Passive OpticalNetwork) system; OLT wherein is through extended operation management maintenance (eOAM, extended OperationAdministration and Maintenance) passage, the energy saver mode information of the current support of acquisition request ONU; ONU sends to OLT through the eOAM passage with the energy saver mode information of self current support.
For Gigabit Passive Optical Network (GPON; Gigabit-Capable Passive Optical Network) system; OLT wherein is through the energy saver mode information of ONU management control channel (OMCI, ONU Management and ControlInterface) the current support of acquisition request ONU; ONU sends to OLT through OMCI with the energy saver mode information of self current support.
For the simple principle of trying one's best in accordance with ONU, require OLT to support multiple energy saver mode simultaneously.Concrete, do not support any energy saver mode if ONU is current, then the OLT configuration is empty (content in this tabulation representes that promptly ONU can select the energy saver mode that uses) to the content of energy saver mode tabulation that should ONU;
Only support a kind of energy saver mode if ONU is current, and this energy saver mode OLT supports also, then the OLT configuration is the energy saver mode of the current support of this ONU to the content of energy saver mode tabulation that should ONU;
If the multiple energy saver mode of the current support of ONU, then OLT configuration is to the content of energy saver mode tabulation that should ONU, is the common factor of the energy saver mode that energy saver mode and OLT supported of the current support of this ONU.
For example: the energy saver mode that OLT supported comprises energy saver mode (1), energy saver mode (2) ... energy saver mode (n); Do not support any energy saver mode if ONU is current; Then OLT can't be successfully dispose any energy saver mode to this ONU, thereby configuration be a sky to the content of energy saver mode tabulation that should ONU;
If the current energy saver mode (1) of only supporting of ONU; Then OLT can support the information of energy saver mode (1) according to the ONU that gets access to; Confirm that it is energy saver mode (1) that OLT goes up configurable energy saver mode to this ONU, the follow-up energy saver mode (1) that will adopt carries out administration of energy conservation to this ONU; Having only energy saver mode (1) in the tabulation of the configurable energy saver mode of this ONU;
Support multiple energy saver mode simultaneously if ONU is current; Then the information of the OLT multiple energy saver mode of support that can report according to ONU is held consultation, and the common factor of the energy saver mode that OLT and ONU are supported is as the optional energy saving pattern of ONU (to the content of energy saver mode tabulation that should ONU); The selection of the energy saver mode of follow-up this ONU of being directed against can only be selected from this occurs simultaneously, otherwise can't configuration successful.
