Machine room centralized monitoring system and monitoring method based on EPON (Ethernet Passive Optical Network) networking

Abstract

The invention provides a machine room centralized monitoring system based on EPON (Ethernet Passive Optical Network) networking, which comprises a first optical network unit, an optical splitter, an optical line terminal and a plurality of network management clients arranged in a core machine room, and further comprises second optical network units arranged in peripheral machine rooms, the first optical network unit and the second optical network unit are connected to the optical line terminal through the optical splitter, the first optical network unit is interconnected with the plurality of network management clients, and the second optical network unit is interconnected with each server in a corresponding peripheral machine room. The network management clients are respectively used for accessing the servers in the core machine room and the peripheral machine room, and the optical line terminal is interconnected with the servers in the core machine room through a network network. According to the invention, networking is carried out based on the EPON, and the network structure is simple and visual; the default isolation performance of the physical port of the ONU further improves the network transmission reliability; the optical branching device ODN can save main optical cable resources to the maximum extent and save cost.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a centralized monitoring system and monitoring method for a computer room based on EPON networking. Background technique [0002] When planning the deployment of a communication system, the principle of nearby deployment is usually followed. An aggregation site is set up at the user aggregation site, and a communication system is deployed to cover surrounding users, which can save the cost of home entry to a certain extent. When deploying the communication system, the supporting network management server and network management terminal will be deployed simultaneously for the management and daily maintenance of the entire system. The maintenance personnel operate on the network management terminal, and transmit the maintenance data to the network management server, and then the server transmits the maintenance data to the equipment running continuously in the for...

Problems solved by technology

However, it does not reduce the occupation of backbone optical cable resources; the port isolation function on the switch is disabled by default, and some low-performance switches do not have the port isolation function, which has certain network security risks; in the later period of network maintenance, fool-type (Non-managed) switches cannot log in remotely, and cannot view port status to quickly locate faults

For network-managed switches, although you can remotely log in to check the port status, it is usually after the event, that is, after the client is found to be unable to operate normally, the fault has occurred for a period of time, which directly affects the processing efficiency of the fault; the number of switch ports is large. There will be a large number of idle ports dedicated to the private network, resulting in waste in use and increasing costs in disguise
