Description
Technical field
The present invention relates to a kind of method of real-time of ONU equipment operation condition, belong to communication network comprehensive management technology field.
Background technology
EPON (ethernet passive optical network) communication network is to adopt point-to-multipoint topological structure, comprehensive ethernet technology and PON(EPON) advantage of technology, signal is at optical line terminal (Optical Line Terminal, OLT) and between optical network unit (Optical Network Units, ONU) transmit.The EPON(ethernet passive optical network) be a kind of novel Optical Access Network technology, it adopts point-to-multipoint structure, passive fiber transmission, and multiple business is provided on Ethernet.It has adopted the PON technology in physical layer, uses Ethernet protocol at link layer, utilizes the topological structure of PON to realize the access of Ethernet.Therefore, it combines the advantage of PON technology and ethernet technology: low cost; High bandwidth; Autgmentability is strong, flexibly service reconfiguration fast; Compatibility with existing Ethernet; Management etc. easily.A PON(EPON) comprise an optical line terminal (OLT) that is installed on console for centralized control, a collection of supporting a plurality of optical network units (ONUs) that are installed on customer site of one-level.
The chain structure that EPON is natural and cheap terminal ONU make it to become the most suitable mesolow distribution communication.
According to statistics, the power outage that suffers of power consumer causes (deduction generation deficiency factor) by power distribution network more than 95%.In distribution automation system, ONU equipment usually for the ease of power taking and use, usually be deployed in switching station, load center, electric supply meter place, ring main unit, on-pole switch, transformer etc. and locate, because environment of living in is abominable, the frequency that breaks down is higher.According to the PON network failure Distribution Statistics investigation of Japanese NTT communication company (beginning FTTH built in 2003), the ONU fault has accounted for 69%.
Therefore, ONU equipment is carried out Real Time Monitoring, find early fault, and measure exactly abort situation, be convenient in time isolate and repair fault, ensure to greatest extent ONU equipment reliability service.Ensure that the distribution automation service communication is unimpeded, be of great significance improving the power supply reliability tool.
Alarm is a kind of event report of the circular formation that managed object is sent when particular event occurs, and is used for transmitting warning information.It is that device fabrication manufacturer oneself defines, and produces by the equipment in network, is the message that system sends, and represents that certain thing or abnormal has occured for it, is finally observed by the network management personnel.
Yet, the corresponding a plurality of ONU of PON mouth due to 1 OLT, ONU equipment is equivalent to the remote end module of OLT, cause the also corresponding growth of network operation fault warning information scale and complexity, the failure cause judgement is more complicated, only by producer's equipment alarm, is difficult to find the ONU equipment fault, often after the failure of power distribution automation devices communicating, just find the ONU equipment fault.
The fault of ONU equipment is divided into three major types, and the one, communication disruption, the 2nd, communicate by letter impaired, the 3rd, performance is impaired; Because ONU equipment has two PON mouths usually, lead to respectively two OLT PON mouths, one is in line states at ordinary times, and another is in dormant state.All be in malfunction if two PON mouths of ONU lead to the passage of OLT PON mouth, the ONU equipment fault is communication disruption; Iff being that a passage is in malfunction, system can automatically switch and remain a normal passage, and this type of fault is impaired for communication; If two passages all are in upstate, but due to spread of voltage, the PON mouth is dirty etc., and reason causes hydraulic performance decline or the potential hazards such as data packet loss, and this type of fault is that performance is impaired.Observe and research through long-time, what the discovery user was concerned about the most is the fault of the first and second classes, has therefore studied emphatically Real-Time Monitoring and has found communication disruption and the method for impaired this two classes fault of communicating by letter.
Summary of the invention
