Data configuring and controlling method for optical network unit

Abstract

The invention provides a data configuring and controlling method for optical network units. Each of one storage unit and four task threads of an optical line terminal performs the own functions, so that the data configuring operations of the various optical network units in a network can be processed in parallel, and then the occupation of the task system resource of the optical line terminal caused by excessive task threads is substantially reduced; in addition, each optical network unit receives an OAM (operation administration and maintenance) configuration data message every other one polling cycle T0 under the condition that the optical network unit is smoothly communicated with the optical line terminal, so that a plurality of optical network units are configured in parallel, the problem that the overall consumed time for downloading the data configuration of the optical network units is too long because of excessive optical network units registered at the same time in the network is avoided, the reliability of data configuration is guaranteed through a retransmission mechanism, the expanded OAM configuration mode defined in China Telecom's technical requirements for EPON equipment and technology becomes compatible, and a higher execution efficiency of data configuration of the optical network units is guaranteed.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to the technical field of passive optical fiber network communication, and in particular to an optical network unit data configuration control method. Background technique [0002] Passive Optical Network (PON for short) refers to ODN (Optical Distribution Network, optical distribution network) that does not contain any electronic devices and electronic power supplies, and ODN is composed of passive devices such as optical splitters (Splitter) composed of fiber optic networks. A passive optical network is mainly composed of an optical line terminal (Optical Line Terminal, OLT for short) installed in a central control station, an optical distribution network (ODN) including optical fibers and passive optical splitters or couplers, and a batch of supporting It consists of an Optical Network Unit (ONU for short) installed at the user's site. In the downlink direct...
