Embodiment 1

[0040] like figure 2 As shown, the embodiment of the present invention provides a method for the OLT to realize the simultaneous registration of a multi-rate ONU under a 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 and the optical line terminal OLT are connected 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 of the rate capability supported by the ONU in the message ;

[0043] S300, after the OLT receives the SN PLOAM message sent by the ONU, analyze and obtain the rate capability supported by the ONU, and save;

[00...

Embodiment 2

[0049] like image 3 As shown, the embodiment of the present invention provides another method for coexistence of multi-rate ONUs, and the method includes:

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

[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 of the rate capability supported by the ONU in the message ;

[0053] S300, after the OLT receives the SN PLOAM message sent by the ONU, analyze and obtain the rate capability supported by the ONU, and save;

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

[0055] Th...

Embodiment 3

[0057] like Figure 4 As shown, the embodiment of the present invention provides yet another method for coexistence of multi-rate ONUs, and the 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 the supported rate capability parameter into the 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 the OLT receives the SN PLOAM message sent by the ONU, analyze and obtain the rate capability supported by the ONU, and save;

[0062] S400, the ONU and the OLT both exchange management messages, including embedded OAM and OMCI, through channel 1, and perform service data exchange through corresponding channels 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 storage medium, belonging to the technical field of communication. The method includes: acquiring the rate capability supported by the ONU, and performing service data interaction through a channel corresponding to the rate according to the rate capability supported by the ONU. In the multi-rate ONU coexistence method, network equipment and storage medium provided by the embodiment of the present invention, the 100G-PON system can be compatible with 25G / 50G ONU, and the technology that solves the conflict between the 100G-PON system and the existing low-rate ONU problems, thus facilitating the deployment and smooth upgrade of 100G‑PON systems.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, network device and storage medium for coexistence of multi-rate ONUs (Optical Network Unit, Optical Network Unit) in a 100G-PON (100-Gigabit-Capable Passive Optical Network) system. Background technique [0002] Due to the rapid upgrading of access network technology, huge scale, 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 components, it is the top priority 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, and after 10G-PON, 25G / 40G optical devices have the characteristics of technology-intensive and high cost, and the industry chain has yet to be cultivated. The bandwidth of high-speed optical devices is the core factor to ens...
