Problems solved by technology

However, when a large number of ONUs go online and offline at the same time, and ONU configurations are issued, data packets may be lost due to data channel congestion. The control panel cannot update its own registry and the online status of the ONU in the authorization table, resulting in inconsistent ONU status between the main control panel and the line card, resulting in information confusion

Abstract

The invention provides a method for retaining synchronous ONU (Optical Network Unit) states in a master control panel and a line card. The method comprises the following steps: adding ONU into a registry of the line card in an ONU registering process when the ONU is on-line; searching an ONU authorization list on the line card according to an MAC (Media Access Control) address of the ONU or logical identification information LOID; determining that the ONU is authorized if the ONU is in the authorization list; determining that the ONU is not authorized if the ONU is not in the authorization list and obtaining information of the ONU; reporting the on-line state of the authorized ONU and the information of the unauthorized ONU when a timer reaches the preset time to the master control panel. According to the technical scheme, the timer is used for triggering the report of the ONU state and the ONU information, so that the problem of the inconsistent ONU states in the master control panel and the line card caused by line congestion can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of optical access communication, in particular to a method for keeping the state synchronization of the main control disk and the ONU in the line card. Background technique [0002] In the rack-mounted OLT system, the distributed management method is generally adopted. One main control panel manages multiple EPON line cards. According to the different types of line cards, each line card manages 8 or 16 PONs. Each PON port is connected to 32 or 64 ONUs through an optical splitter. [0003] When an ONU accesses or leaves the line card, the line card will send the relevant information of the connected ONU or the departed ONU to the main control panel through the inter-board communication message, and the main control panel will add or delete the registered ONU and Modify the status of the ONU in the authorization table to be online or offline. [0004] Specifically, after the ONU registers on the online card ...
