Problems solved by technology

[0006] In consideration of the problems of high cooperation between OLT and ONU and poor scalability in reporting port location information in the related art, the present invention is made. For this reason, the main purpose of the present invention is to provide a port location method to Solve the above-mentioned problems in related technologies, realize the port positioning information of both OLT and ONU is reported separately by OLT or ONU

example 1

[0033] Example 1: The ONU is responsible for reporting port location information.

[0034] In the first step, the ONU listens to the DHCP request packet, and inserts the port location information related to the PON system in the OPTION82 field;

[0035] In the second step, since the OLT is not responsible for reporting port location information, the OLT does not listen to the DHCP request packet, and the OLT writes its own port location information to the ONU;

[0036] In the second step, taking the GPON system as an example, the specific writing operation is: the OLT adds several attributes to the ONT2-G management entity in the ONU, including:

[0037] OLT identifier, OLT identifier, 1 byte, read and write;

[0038] OLT rack, the OLT rack number related to the ONU, 1 byte, read and write;

[0039] OLT shelf, the OLT shelf number related to the ONU, 1 byte, read and write;

[0040] OLT slot, the OLT slot number related to the ONU, 1 byte, read and write;

[0041] OLT port...

example 2

[0045] Example 2: The OLT is responsible for reporting port location information.

[0046] In the first step, the OLT listens to the DHCP request packet, and inserts the port location information related to the PON system in the OPTION82 field;

[0047] In the second step, since the ONU is not responsible for reporting port location information, the ONU does not listen to the DHCP request packet, and the OLT actively obtains the relevant port location information of the ONU port;

[0048] In the second step, taking the GPON system as an example, the operation of actively obtaining the location information of the ONU port is as follows: bind the ONU port to the GEM-PORT, and add several attributes to the GEM portnetwork CTP management entity, including:

[0049] ONU rack, ONU rack, 1 byte, read and write;

[0050] ONU shelf, ONU frame, 1 byte, read and write;

[0051] ONU slot, ONU slot, 1 byte, read and write;

[0052] ONU port, ONU port, 1 byte, read and write;

[0053] ONU...

example 3

[0058] Example 3: The OLT or the ONU reports port positioning information according to different types of ONUs.

[0059] The first step is to classify the ONU, and can be divided into the following types:

[0060] SFU type: used for home ONT not including home gateway function, applied to ONU of FTTH architecture type; HGU type: used for family ONT including home gateway function, and applied to ONU of FTTH architecture type; SBU type: used for single ONT exclusive to business users, and applied to ONU of FTTH architecture type; MDU type: ONU for multi-family users, and, applied to ONU of FTTB / FTTC architecture type; MTU type: ONU for multi-business users, And it is applied to the ONU of FTTB / FTTC architecture type;

[0061] Second step, for the ONU of MDU / MTU type, port location information is reported by ONU, and OLT writes relevant port location information to ONU (as described in example 1);

[0062] In the third step, for the ONU of SFU / HGU / SBU ​​type, the port location...

Abstract

The invention discloses a port positioning method and a port positioning device. The method comprises the following steps that: an optical line terminal or an optical network unit independently intercepts a related protocol and fills port positioning information of the optical line terminal or the optical network unit in scheduled fields of the related protocol, and the optical line terminal or the optical network unit independently reports the port positioning information to an authentication server. The technical scheme can reduce the cooperation between the optical line terminal and the optical network unit and improve the system expandability.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a port positioning method and device. Background technique [0002] In order to perform fault location and security traceability on users and their ports, operators need to locate users' ports to obtain user location and service flow path information. The port location information is carried to the authentication server through a special protocol or method. For example, the device listens to the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, referred to as DHCP), Ethernet Point-to-Point Protocol (Point-to-Point Protocol overEthernet, referred to as PPPoE) related protocol package, and fill in the port location information in the corresponding field. [0003] Passive Optical Network (PON) system consists of Optical Line Terminal (OLT), Optical Network Unit (ONU) and Optical Distribution Network (ODN) Composition, the ONU is applied to the...
