Problems solved by technology

[0008] The disadvantages of this method are: 1. It occupies the VLAN resources of the system; 2. The VLAN with the business flow of the management VLAN needs to be changed to another VLAN by using VLAN conversion or other functions, which is troublesome to deal with.

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment:

[0027] The network management personnel limit the port rate of the ONU through the EMS, and manage it through the in-band network management. It is planned to use the service port 1 as the management channel, and the management MAC of the CPU is 00:20:ED:16:EC:6C.

[0028] like image 3 As shown, the OLT consists of three main physical modules: CPU board, switch board and PON board. The CPU board is responsible for the processing of protocol control flow and configuration management flow in the system. The switching board is responsible for the forwarding of flows in the system. PON board negative table PON-related functional processing in EPON system.

[0029] The service flow and the management flow come down the same channel, firstly reach the switching board, and then go to the PON board or CPU board. Due to the limited processing p...

Abstract

The utility model relates to the equipment management in the Ethernet-PON, more particularly, the in-band control method in the Ethernet-PON. The method comprises following steps as OLT's CPU board is arranged with the MAC control and in-band control channel port for the CPU board. Also, the MAC control can be arranged in the MAC register in the exchange board; when the CPU board receives the OLT control order, the relevant processing shall be conducted, while as the CPU board receives the ONU control order, such order can be sent to ONU via PON board. The utility model introduces a functional character of the exchange chip and the uniqueness of MAC, so as to handily realize the in band network administration of the EPON system and avoid the occupation of the system's VLAN resources and address clash arising from the introduction of the other methods.

Description

technical field [0001] The invention relates to the management of equipment in the Ethernet passive optical network, especially the method for realizing in-band management in the Ethernet passive optical network. Background technique [0002] There are many data flows in the network, such as user service flows, protocol control flows to maintain the normal operation of user service flows, and various management flows to manage the network. These flows may be transmitted in the same channel or in different channels. In terms of whether the management flow and the service flow use the same physical channel, it can be divided into two modes: in-band management and out-of-band management. In-band management: The management information flow of the network and the service information flow of the user are transmitted through the same channel. Out-of-band management: refers to the transmission of network management control information flow and user service information flow in diffe...
