Method and device for realizing configuration data synchronization in a pon system

Abstract

The invention discloses a method and device for realizing configuration data synchronization in a PON system, and relates to the technical field of passive optical networks. The method comprises the steps that: after an information management system successfully modifies ONU configuration data, an ONU stores the modified ONU data and reports a configuration change message to an OLT; after the OLT receives the configuration change message, the OLT carries out configuration data synchronization with the ONU; after the OLT and the ONU completed configuration data synchronization, the configuration change message is reported to an EMS network management server; and the EMS network management server issues a synchronization command after receiving the configuration change message and carries out configuration data synchronization with the OLT. According to the invention, timely synchronization of the configuration data of the PON system is realized, the consistency of system configuration is ensured, and the workload of management and maintenance is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of PON (Passive Optical Network, Passive Optical Network), in particular to a method and device for realizing configuration data synchronization in a PON system. Background technique [0002] Passive optical network technology is a broadband optical access technology based on optical fiber. A passive optical network system (PON system) generally includes an OLT (Optical Line Terminal, Optical Line Terminal) and several ONUs (Optical Network Unit, Optical Network Unit). Because the PON system has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces, most operators use this technology to realize broadband and comprehensive transformation of access network services, and have been widely deployed and obtained a large number of users experience. [0003] With the development of PON technology, there are more and more management methods for ONU, mainly includi...

Problems solved by technology

[0004] However, in the existing management method, because the ONU of the PON system does not actively send configuration data to the OLT, it can only passively wait for the configuration update of the OLT. Data out of synchronization between ONUs, similarly, this situation also exists between OLT and network management

In this way, the ONU will be disconnected, so that the service update of all users under the ONU cannot be sensed by the network management system in time and it is difficult to synchronize, thereby increasing the workload of management and maintenance.
