Method for managing optical network unit in passive optical network (PON) system

Abstract

The invention discloses a method for managing an optical network unit (ONU) in a passive optical network (PON) system and relates to the field of broadband optical fiber access in the PON system. The method comprises the following steps that: 1, the ONU is powered on and transmits a broadcast message which carries a virtual local area network (VLAN) identifier to an optical line terminal (OLT); 2, the OLT authorizes the ONU, and transmits configuration of a management Internet protocol (IP) or configuration which modifies a management IP network segment to the ONU according to a management IP allocating rule, wherein the management IP allocating rule defines payload contents of a data field of a standard layer-two protocol message, the payload contents carry management IP information, an IP address format is 10. A1. A2. A3, the A2=card slot number of an OLT service disk*10+PON port number, the card slot number of the service disk is between 1 and 16, and the port number is between 1 and 8; and 3, the PON completes the configuration according to a layer-two protocol message which is replied by the OLT. By the method, the function of positioning and maintaining the ONU in various PON systems can be realized.

Description

technical field [0001] The invention relates to the field of broadband optical fiber access in a passive optical network system, and specifically relates to a management method for an optical network unit in a passive optical network system. Background technique [0002] Passive Optical Network (PON for short) system mainly consists of the optical line terminal (Optical Line Terminal, OLT for short) of the central office, the optical distribution network (Optical Division Network, ODN for short) including passive optical devices, user It consists of an optical network unit / optical network terminal at the end and an element management system (EMS), and usually adopts a point-to-multipoint tree topology. [0003] At present, the PON system can be divided into Gigabit-Capable PON (EPON for short) and EPON-ETHER PON (GPON for short) due to the use of different layer-2 technologies. No matter what kind of PON system, there are management and maintenance standards for ONU. For e...

Problems solved by technology

For example, the existing Operation Administration and Maintenance (OAM) standard can provide ONU management under the EPON system, and the management and control interface standard (ONT Management and Control Interface ONT, OMCI) can provide the ONU ONU under the GPON system. management, but these two standards cannot be used universally in different PON systems

Even if there is an extended standard to realize ONU location management, it must rely on the OAM or OMCI standard itself, and the configuration process is too complicated
