OLT side ONU automatic discovery method and device based on SNMP

Abstract

The embodiment of the invention provides an SNMP (Simple Network Management Protocol)-based OLT (Optical Line Terminal) side ONU (Optical Network Unit) automatic discovery method and device. The method comprises the following steps of: acquiring ONU information on an OLT in batches through an SNMP (Simple Network Management Protocol); judging the running state of the ONU according to the ONU information, wherein the on-line state comprises an on-line state and an off-line state; and judging whether the ONU exists in a network management system or not, and finding the ONU. In this way, the ONU information on the OLT can be directly collected through the SNMP, the collection speed is high, the information is complete, distributed deployment and concurrence are easier, the ONU information of different OLT can be collected in batches and concurrence generally, discovery can be conducted many times every day, complete ONU information can be collected, accurate information of the latest ONU can be maintained and updated in real time, a third-party EMS network management does not need to be connected, and the cost is reduced. And manufacturer differentiation can be shielded.

Description

technical field [0001] Embodiments of the present invention generally relate to the communication field, and more specifically, relate to an SNMP-based OLT-side ONU automatic discovery method and device. Background technique [0002] With the development of network technology and the development of optical access and copper output, the access network now uses optical fiber access, and home broadband is usually directly accessed through an optical modem, such as FTTH ONU. In the access network, the ONU is usually managed by the OLT side management equipment, but it is difficult to manage the ONU because the number of the equipment is huge and changes every day. It is impossible to maintain the ONU by entering the ONU information every day. The usual access network management discovers ONUs through the manufacturer's network management EMS. The number of ONUs is extremely large. ONU discovery based on EMS cannot achieve higher concurrency due to restrictions on the login side ...

AI Technical Summary

Problems solved by technology

In the access network, the ONU is usually managed by the OLT side management equipment, but it is difficult to manage the ONU because the number of equipment is huge and changes every day. It is impossible to maintain the ONU by entering the ONU information every day.

The usual access network management discovers ONUs through the manufacturer's network management EMS. The number of ONUs is extremely large. ONU discovery based on EMS cannot achieve higher concurrency due to restrictions on the login side and the device side, resulting in slow discovery speed and low efficiency. Very little information was found
