Specific embodiment
Below with reference to Fig. 1-Fig. 2 and specific embodiment, the present invention will be further described.
As Figure 1-Figure 2, the present embodiment is from the status and adapted telecommunication network service of adapted telecommunication net to network
It is required that setting out, the existing every business of electric system is analyzed to other network quality parameters such as bandwidth and network delay, and combine
The multifarious development need of adapted electrical network business, it is proposed that the method for main passive probe cooperative adapted electric channel quality.
The present embodiment is related to a kind of method for leading passive probe cooperative adapted electric channel quality comprising following step
It is rapid:
The many kinds of and every class business of intelligent power distribution communication service requires each not phase to the bandwidth and propagation delay time in channel
Together.Adapted telecommunication business has Intelligent power distribution terminal communication service, energy storage station status monitoring business, distributed busbar protection control letter
Breath business, equipment running status monitor business, the information collection industry of distributed busbar protection curve prediction information service, transformer
Business and load seek survey management business.
The method is divided into two parts, evaluates first quality of service, then according to the evaluation result of quality of service
Overall merit is carried out to adapted electric channel quality.
(1) the service quality Q evaluation of business:
1) evaluation parameter of the service quality Q of business is obtained:
Every kind of adapted telecommunication business is different to the performance index requirements in distribution, by time delay, shake, the bit error rate, loss
Parameter of the rate as network performance, using Mean Speed as flow parameter, by these network parameters and flow parameter to biography
The distribution channel quality of defeated different business measures.
2) evaluation parameter of the service quality Q of business is calculated:
Main passive probe is configured in distribution, measures the network performance parameter and flow parameter in distribution channel, and to this
A little parameters are calculated, and the service quality Q of evaluation assignment is carried out.
If the state value of network performance is indicated with service quality Q, critical point Q '；When the network performance parameter includes
Prolong state value, dither state value, bit error rate state value and packet loss state value；

The quality in road, then in the main passive probe of optical line terminal OLT terminal link, main passive probe replicates flow information,
It realizes and the channel quality of optical line terminal OLT to optical network unit ONU is detected.
The specific measurement method of the present embodiment is as follows:
Step 1: the passive probe A of master is deployed between data center and optical line terminal OLT, monitors same period internetworking
It can state；The passive probe B of master is deployed between optical line terminal OLT and optical network unit ONU, same period network flow shape is monitored
State.
Step 2: related data is acquired by the passive probe A of master and main passive probe B, according to calculation method above
Data center is calculated to optical line terminal OLT and optical line terminal OLT to the comprehensive of optical network unit ONU both ends different light paths
Close the service quality of quality and different business.
Step 3: according to calculated result with sequence from big to small by data center to optical line terminal OLT and light
Road terminal OLT is matched to two sections of different optical paths of optical network unit ONU, obtains a matching sequence.Specifically matched
Journey is as follows:
A random number a is generated, the quantity m remainder of the adapted electric channel of data center to optical line terminal OLT is obtained
B, then in the channel of data center to optical line terminal OLT, the adapted electric channel of comprehensive quality ranking i-th is just and optical line terminal
OLT adapted electric channel of ranking (i+b)/n into n articles of adapted electric channel of optical network unit ONU matches.
Step 4: after a measurement period, matching sequence is updated.
Step 5: Step 4 is repeated, the real-time monitoring of adapted electric channel quality is achieved in.
Process based on the passive probe cooperative adapted electric channel quality real-time monitoring strategy of master is as shown in Figure 2.
Above-mentioned detailed description is illustrating for possible embodiments of the present invention, and the embodiment is not to limit this hair
Bright the scope of the patents, it is all without departing from equivalence enforcement or change of the invention, it is intended to be limited solely by the scope of patent protection of this case.
