Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] In the existing management method, all the configurations of the ONU are sent to the ONU one by one by the OLT through the OAM message. When the number of ONUs connected to the OLT device is large, the burden on the OLT will be too large. For this reason, the present invention provides a kind of 10GEPON system power-off and restarts the method for business rapid recovery, comprises the following steps:

[0040] Step 1, generation of ONU batch configuration files.

[0041] The OLT generates and saves corresponding batch configuration files for each ONU respectively. The content of the batch configuration files is all configuration information issued by the EMS for the ONU; the batch configuration files and ONUs are in a one-to-one relationship. How many ONUs are there? There are as many batch configuration files as there are; the specific process is as...

Abstract

The present invention relates to a 10G? In the method and system for quick service recovery after the EPON system is powered off and restarted, the optical line terminal OLT generates and saves corresponding batch configuration files for each optical network unit ONU. When 10G? After the EPON system is powered off and restarted, the OLT directly sends the batch configuration files corresponding to each ONU to each ONU; each ONU analyzes the batch configuration files sent from the OLT, and automatically configures the ONUs according to the contents of the batch configuration files. 10G? After the EPON system is powered off and restarted, a large number of ONUs connected in the system will go online at the same time. The method and system of the present invention can issue batch configuration files to the ONUs on the optical line terminal OLT, and each optical network unit The ONU independently executes batch configuration files to complete automatic configuration, achieving the purpose of reducing the interaction between the optical line terminal OLT and the optical network unit ONU, thereby solving the problem of excessive burden on the optical line terminal OLT and realizing rapid service recovery.

Description

technical field [0001] The present invention relates to the rapid recovery of optical network unit services in the technical field of network communication, in particular to a method and system for rapid recovery of services after a 10GEPON system is powered off and restarted. In particular, it refers to a method and a system for quickly restoring services of an optical network unit after a 10GEPON system is powered off and restarted. Background technique [0002] Passive Optical Network (PON, Passive Optical Network) technology is one of the most widely used optical fiber access technologies at present. The PON system structure usually consists of three parts: the optical line terminal (OLT) at the central office, the optical distribution network (ODN) for transmission, and the optical network unit (ONU) at the user end. Among them, the OLT is located at the central office CO (CENTRALOFFICE), and the ONU is located at the user end. [0003] PON adopts a single-fiber bidir...
