Problems solved by technology

The purpose of this kind of manual authorization ONU is to prevent the access of illegal ONUs by this means. MAC address and other identification information, and the administrator manually enters the information of the ONU, so that the ONU can be authorized to access the network. This method is not only difficult to maintain, but also cumbersome. Therefore, the OLT needs to provide an automatic authorization method. After the ONU is registered, the OLT automatically authorizes the ONU and allocates the required bandwidth and other resources.

Embodiment Construction

[0037] based on the following figure 1 , specifically explain the preferred embodiment of the present invention.

[0038] Such as figure 1 As shown, the present invention provides a kind of method that realizes ONU automatic authorization in EPON system, and this method comprises the following steps:

[0039] Step 1. After the ONU device and the OLT central office device are powered on and connected, the OLT discovers that the ONU is online through periodic broadcast discovery messages, and the ONU sends a registration request to the OLT after receiving the discovery message;

[0040] Step 2, OLT responds to the registration request of ONU, and ONU reports its physical address information to OLT, and OLT writes the physical address information of ONU into the ONU registry to complete the registration;

[0041] Step 3. Switch the OLT system to the automatic authorization mode, and search the authorization table items in order according to the authorization number;...

Abstract

The invention provides a method for realizing ONU automatic authorization in an EPON system. On the basis of existing manual authorization, the automatic authorization ONU mechanism is added to make an ONU registered to an OLT system authorized automatically so as to make all data services of the ONU pass through to ensure that the ONU can conveniently access to the network, so that the maintenance in conditions, such as the authorization of a large number of ONUs, the frequent replacement of the ONUs, etc., can be greatly facilitated.

Description

technical field [0001] The invention relates to a method for realizing ONU automatic authorization in an EPON system. Background technique [0002] EPON is a point-to-multipoint system composed of OLT (Optical Line Terminal), ONU (Optical Network Unit) and ODN (Optical Distribution Network). The OLT is located at the central office, the ONU is located at the user end, and the ODN consists of passive optical splitters and optical fiber lines. [0003] According to the requirements of China Telecom's EPON standard specification, the ONU connected to the network through the OLT needs to be registered and authorized. The OLT system should support the authorization of the ONU (authorized), and the authorization status of the ONU determines whether the ONU can access the network. The OLT has a database of legal ONU identification information. For an authorized ONU, the OLT directly sets the ONU to an authorized state, allowing data services from the ONU to pass through. The aut...
