Problems solved by technology

[0003] In addition, when the optical network unit is connected to the optical network, the optical network management system needs to restore the configuration of the device immediately. If the system manager uses TL1 / CL1 to configure the device, then this will happen The configuration fails; secondly, the restart of the optical network unit will also cause the configuration recovery time of the entire system to be too long

Abstract

The invention relates to a method for configuring an ONU in a PON in an optical access communication network. The PON further comprises an OLT, and the method comprises the steps that a mapping relation table between formal LLIDs distributed by the an optical network management system and the MAC address and/or the serial number of the ONU and an authentication mode related to the ONU are built and stored in the OLT; when the ONU initiates a login request for having access to the PON, the OLT initiates an authentication request to the ONU, and whether the ONU is authorized or not is judged according to the mapping relation table and the authentication mode; if the ONU is authorized, the ONU is allowed to sent data flow and protocol flow; otherwise, the ONU is deregistered. All the other configuration in the OLT is based on the formal LLIDs, and the MAC address or the serial number of the ONU are not depended on any more. The method solves the correlation problem of the MAC address or the series number identifying the ONU and the formal LLIDs, all the configuration in the OLT is based on the formal LLIDs, and therefore the offline configuration of the ONU is achieved.

Description

technical field [0001] The present invention relates to wired communication technology, in particular to a method for configuring an optical network unit in a passive optical network in an optical access communication network. Background technique [0002] Various configurations in the existing optical access communication network are based on the MAC address of the optical network unit, which causes many problems. For example, after an optical network unit fails, it needs to be replaced by another optical network unit with a different MAC address. At this time, the previous configuration needs to be deleted, and then a new configuration should be created based on the new MAC address. On the one hand, this increases the difficulty for the realization of the system, on the other hand, it also makes the system not stable enough, and the configuration of the system must be updated along with the update of the optical network unit. In addition, the ONU can be configured by the ...
