Embodiment Construction

[0029] Aiming at the defects of logical port occupation and heavy maintenance work in the OLT locally binding the downlink port with the ONU MAC in the prior art, the following technical solutions are proposed.

[0030] Firstly, the embodiment of the present invention provides an EPON network element configuration method, which centralizes the authentication configuration originally scattered on the access layer device OLT to the access server, and realizes unified management of ONU authentication.

[0031] It can be seen that this embodiment utilizes the access server and adopts a remote authentication method to authenticate the ONU; those skilled in the art can understand that through the design of the protocol interaction message support attribute and the transformation of the attribute field in the protocol message, each Various remote authentication methods can be used here, for example: DHCP Option82 protocol (DHCP: Dynamic Host Configuration Protocol, Dynamic Host Config...

Abstract

A method for configuring EPON network element includes configuring binding relation of MAC address of ONU to down-link port of OLT in access server, carrying out certification on ONU login information reported by OLT by access server as per binding relation when an ONU is logged in, down-sending access permission information to OLT by access server if certification is passed, obtaining logic port by OLT automatically according to access permission, configuring ONU service information on logic port and releasing logic port when ONU is unlogged. The EPON network applying said method is also disclosed.

Description

technical field [0001] The invention relates to the field of communication access networks, in particular to an Ethernet Passive Optical Network (EPON for short) network element configuration method and an EPON. Background technique [0002] A typical EPON system is shown in Figure 1. It consists of an optical line terminal (Optical LineTerminal, OLT for short), an optical network unit (Optical Network Unit, ONU for short) at the user side, and an optical distribution network (Optical Distribution Network, short for ONU). ODN) composition. Wherein, any OLT includes an uplink interface and several downlink ports (for example, 8 downlink ports, 48 ​​downlink ports, etc.), and its uplink interface is used to provide the optical interface between the access network and the core network, and each of its downlink ports Composed of a certain number of logical ports, it can provide access support for at most this number of ONUs on a single fiber through the ODN. [0003] In the pr...
