Embodiment Construction

[0055] In the present invention, the OLT single disk collects the ONU information obtained by the EPON core chip, and then reports it to the network management system through a formulated protocol. And intervene in the registration process of the unauthorized ONU. The present invention will be described in detail below.

[0056] Fig. 5 is an overall block diagram of the OLT single disk and the network management system. The EPON core chip in the figure executes the MPCP function stipulated by IEEE802.3ah. The OLT single disk module provides the interface between the network management system and the EPON core chip. Perform operations such as initialization of EPON core chips and OLT single disks and equipment performance statistics and alarms. The function of automatically obtaining and reporting the ONU MAC address proposed by this solution to the network management system is mainly implemented in the OLT single-disk module. The network management system module communicat...

Abstract

The method includes steps: at time of system initialization, based on ONU (optical network unit) MAC address obtained from procedure of multiple points control protocol, building unauthorized ONU MAC address list in OLT (optical line terminal) and reporting it to network manager; network manager carried out authorization for unauthorized ONU reported from OLT single disk; MAC address of unauthorized ONU is transferred to serial number mapped list of authorized ONU to build ONU serial number map list; network managing system distributes the serial number map list down to OLT. The disclosed OLT single disk capable of automatic reporting MAC address to network managing system includes a module for maintaining an unauthorized list, receiving and comparing module etc. The invention realizes functions: reporting MAC address without need of manual input, distinguishing ONU device first found from authorized ONU device, preventing network resources occupied by illegal user.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, and relates to a method for automatically reporting a MAC address to a network management system by a remote optical network unit (ONU) device in a Gigabit Ethernet-based passive optical network (EPON). Background technique [0002] EPON is a new topology that Ethernet is used in broadband access network. EPON generally consists of a central office node optical line terminal (OLT) located at the root of the tree and multiple remote node optical network units (ONU) located at the branches. The OLT and the ONU are connected through a passive optical distribution network (ODN), as shown in FIG. 1 . The OLT is generally placed on the side of the service provider and connects the optical access network to an IP, ATM or SONET backbone network. The OLT also needs to provide an interface with the network management system (hereinafter referred to as the network management system), so that the...
