Embodiment 1

[0040] Such as figure 2 As shown, the embodiment of the present invention provides a method for OLT to realize the simultaneous registration of multi-rate ONUs under one 100G-PON port through the rate support capability reported by the ONU in the SN message. The optical network in the 100G-PON system The terminal ONU is connected to the optical line terminal OLT through four wavelength channels from the first channel to the fourth channel, and the method includes:

[0041] S100. During the startup process of the ONU, judge the rate capability supported by the ONU through hardware information;

[0042] S200, after the ONU is started, in the SN (O2-3) state, in response to the SN authorization issued by the OLT, send an uplink SN PLOAM message, and notify the OLT in the message of the rate capability supported by the ONU ;

[0043] S300. After receiving the SN PLOAM message sent by the ONU, the OLT analyzes and obtains the rate capability supported by the ONU, and saves it; ...

Embodiment 2

[0049] Such as image 3 As shown, the embodiment of the present invention provides another method for multi-rate ONU coexistence, which method includes:

[0050] S101. When the ONU is started, judge the rate capability supported by the ONU through the model of the optical module;

[0051] S102. The ONU saves the rate capability parameter during operation;

[0052] S200, after the ONU is started, in the SN (O2-3) state, in response to the SN authorization issued by the OLT, send an uplink SN PLOAM message, and notify the OLT in the message of the rate capability supported by the ONU ;

[0053] S300. After receiving the SN PLOAM message sent by the ONU, the OLT analyzes and obtains the rate capability supported by the ONU, and saves it;

[0054] S400, the ONU and the OLT all exchange management messages through channel 1, including embedded OAM and OMCI, and perform service data interaction through the corresponding channel according to the rate capability supported by the ON...

Embodiment 3

[0057] Such as Figure 4 As shown, the embodiment of the present invention provides another method for multi-rate ONU coexistence, which method includes:

[0058] S100. During the startup process of the ONU, judge the rate capability supported by the ONU through hardware information;

[0059] S201. The ONU configures supported rate capability parameters into an uplink SN PLOAM message;

[0060] S202. After receiving the SN authorization issued by the OLT, the ONU sends an SN PLOAM message to the OLT, and notifies the OLT of the rate capability supported by the ONU in the message;

[0061] S300. After receiving the SN PLOAM message sent by the ONU, the OLT analyzes and obtains the rate capability supported by the ONU, and saves it;

[0062] S400, the ONU and the OLT all exchange management messages through channel 1, including embedded OAM and OMCI, and perform service data interaction through the corresponding channel according to the rate capability supported by the ONU.

Abstract

The embodiment of the invention discloses a multi-rate ONU coexistence method, network equipment and a storage medium, and belongs to the technical field of communication. The method comprises the following steps: acquiring rate capability supported by an ONU, and performing service data interaction through a channel corresponding to the rate according to the rate capability supported by the ONU.The embodiment of the invention provides a multi-rate ONU coexistence method, network equipment and a storage medium. According to the invention, the 100G-PON system can be compatible with the 25G / 50GONU, and the technical problem of conflict between the 100G-PON system and the existing ONU with low rate capability is solved, so that the deployment and smooth upgrading of the 100G-PON system canbe facilitated.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for coexistence of multi-rate ONUs (Optical Network Unit, Optical Network Unit) in a 100G-PON (100-Gigabit-Capable Passive Optical Network) system, a network device and a storage medium. Background technique [0002] Due to the rapid upgrade of access network technology, huge scale and high investment, high performance and low cost have always been the key factors determining the evolution of access network technology. Among them, due to the high cost of optical devices, it is the most important thing to be considered in the upgrade of access network technology. At present, the optical device industry chain of E / GPON and 10G-PON has matured, but after 10G-PON, 25G / 40G optical devices have the characteristics of intensive technology and high cost, and the industry chain has yet to be cultivated. The bandwidth of high-speed optical devices is the core eleme...
