Problems solved by technology

[0004] However, there are following defects in the above-mentioned prior art solution: in the above-mentioned technical solution, even if there is only one online ONU in the PON (other ONUs are in a sleep state), the OLT is always in a state of full load (that is, all OLT ports are In active state), in other words, in the case of no downlink business, the OLT system contacts the ONU in the sleep state too frequently. However, in reality, the ONU is not online 24 hours a day, which leads to extreme resource consumption. big waste

Embodiment 1

[0064] refer to figure 1 , an energy-saving control method for an OLT port in a passive optical network disclosed by the present invention, comprising the following steps:

[0065] S10. Determine the working state of the OLT port. The working state of the OLT port includes idle state or active state. Specifically, if the OLT port receives the uplink customer data from the ONU or sends the downlink customer data to the ONU, it is determined that the OLT port is in the active state; if the OLT port is set If the uplink client data sent by the ONU is not received and the downlink client data is not sent to the ONU within the time threshold, it is determined that the OLT port is in an idle state. Wherein, if it is determined that the working state of the OLT port is an idle state, then enter step S20; if it is judged that the working state of the OLT port is an active state, then re-judgment is made on the working state of the OLT port.

[0066] S20. Close the corresponding OLT ...

Embodiment 2

[0081] refer to Figure 4 , is an energy-saving control system for the OLT port 11 in the passive optical network based on the energy-saving control method for the OLT port 11 in the passive optical network in Embodiment 1 disclosed in the present invention, including a detection module 2, a switch module 3, and a control module 4 and trigger module 5. The OLT includes a host 1 and a plurality of OLT ports 11 connected to the host 1 (in this embodiment, the four OLT ports 11 of "OLT port 1", "OLT port 2", "OLT port 3", and "OLT port 4" For example), a plurality of OLT ports 11 are connected to an optical splitter 13 (that is, ODN) through a wavelength division multiplexer 12, and the ODN connection is used to provide an optical channel between the OLT and each ONU.

[0082] refer to Figure 4 , four switch modules 3 are provided, and the four switch modules 3 are all connected to the detection module 2 and respectively connected in series between the host 1 and the correspon...

Abstract

The invention discloses an energy-saving control method and system for an OLT port in a passive optical network, relates to the technical field of passive optical communication, and aims to solve the problem of large waste of resources in the existing passive optical network system. The key point of its technical scheme is to include the steps of: judging the working state of the OLT port, and the working state includes an idle state or an active state; The ONU sends a forced sleep control signal to make the corresponding ONU enter the sleep state; when the ONU exits the sleep state, the ONU exiting the sleep state sends a wake-up message to the OLT, so that the OLT opens the corresponding OLT port. When the OLT port is in an idle state, the port can be closed in time. When the ONU exits the sleep mode, the corresponding OLT port can be opened in time so as not to affect user services, thereby reducing PON (passive optical network) energy consumption. The purpose of saving resources.

Description

technical field [0001] The invention relates to the technical field of passive optical communication, in particular to an energy-saving control method and system for an OLT port in a passive optical network. Background technique [0002] The PON system structure is mainly composed of the optical line terminal (OLT: Optical Line Terminal) of the central office, the optical distribution network (ODN: Optical Distribution Network) including passive optical devices, and the optical network unit / optical network terminal (ONU / ONT Optical Network Unit) at the user end. Network Unit / Optical Network Terminal), the difference is that the ONT is directly located at the user end, and there are other networks between the ONU and the user, such as Ethernet) and the network element management system (EMS), usually using point-to-multipoint The tree topology greatly reduces the number of optical interfaces on the network side, and the access of optical fibers provides greater capacity for...
