Problems solved by technology

The standard SNMP protocol does not clearly stipulate the content of the additional information of the Trap, which not only provides flexibility, but also inevitably leads to arbitrariness and blindness in implementation.
For the EPON access system, the existing SNMP protocol trap operation cannot perfectly manage the abnormal events in the EPON access network

Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Fig. 2 shows a network management structure diagram of the EPON access system. The EPON access system includes EPON central office equipment, which provides a platform for multi-services, provides optical fiber interfaces for passive optical networks, and manages subordinate ONU (Optical Network Unit, optical network unit) equipment. It includes a main control panel, an uplink panel, a narrowband control panel and a line panel, and the line panel is connected to the remote OUN device. The EPON access system also includes a network management computer connected to the EPON central office equipment. The network management computer is equipped with an SNMP manager, and the master control disk of the EPON central equipment is equipped with an SNMP agent. The network management computer completes the management of the equipment through the...

Abstract

The invention relates to a remote network management method for an Ethernet passive optical network. An SNMP proxy is disposed on an EPON optical line terminal. An SNMP management station is disposed on a network management computer. The SNMP proxy establishes a Trap data packet. The variable binding part of the Trap data packet includes shelf number, frame number, slot number, port number, ONU number and ONU port number of event source, interface type field, and field of data related to event content. The SNMP proxy fills in the field related to the event source according to the recorded event source information, and sets the unrecorded field to zero while filling in the data field related to the event content according to the recorded event content information. The network management computer acquires the event source and the event content information by analyzing the Trap data packet via the SNMP management station, and displays the event source and the event content information on a network management interface.

Description

technical field [0001] The invention relates to remote network management, in particular to a remote network management method for an Ethernet passive optical network access system. Background technique [0002] Ethernet Passive Optical System (EPON) is a new type of optical fiber access network technology. It adopts a point-to-multipoint structure and passive optical fiber transmission to provide various services on the Ethernet. It adopts PON technology in the physical layer, uses Ethernet protocol in the link layer, and realizes the access of Ethernet by using the topological structure of PON. Therefore, it combines the advantages of PON technology and Ethernet technology: low cost; high bandwidth; strong scalability, flexible and fast service reorganization; compatibility with existing Ethernet; convenient management and so on. [0003] In recent years, the user scale of the access network has continued to expand, and the workload of network operation, maintenance and m...
