Lead to the business.Therefore, it improves the efficiency of service fulfillment and improves the service efficiency of network bandwidth.
The service activating method based on PTN network performance of above-mentioned implementation in order to better understand, is shown below a tool
The implementation of body, the realization process includes:
Step 1: assessing existing PTN network performance, when being connected to service fulfillment demand according to predetermined
First network index determines the loading level of current PTN network performance.
It is assumed herein that this section of link remaining bandwidth of existing PTN network is able to satisfy service bandwidth demand.Assessment consideration SLCBE,
Tri- parameters of SLRBE and SLPBE, wherein SLCBE and SLPBE is Configuration Values, and without considering statistic, SLRBE need to consider to unite
Metering, as shown in the SLRBE normalized set schematic diagram of Fig. 2, in entire observing time t, the time overall length of SLCBE≤0.7The time overall length of 0.7 SLCBE≤1 <The loading level of entire PTN network performance can
Make following assessment:

Step 2: being based on network performance evaluation state, judge whether business is open-minded.If link is lightly loaded, business can be opened directly
It is logical；If being carried in link, whether matched with the discharge pattern of business according to the discharge pattern of link to determine whether activate the service,
If matching, activates the service, if mismatching, the business is not open-minded on the PTN chain road；If link state is heavy duty,
The business is not open-minded on the PTN chain road.
Specifically, if the loading level is to carry in link, the link and service traffics type matching of such as the following table 1 can be passed through
Table judges whether the discharge pattern of PTN network link and the discharge pattern of the business meet preset matching relationship:

Step 3: configuration service bandwidth, according to type of service, quality of service grade, business demand-expected configuration service
CIR/PIR, wherein PIR should be greater than or equal to the maximum value for expecting flow.
Step 4: being observed after a period of time, whether assessment service bandwidth configuration is reasonable, if rationally, entirely opening stream
Journey terminates；If unreasonable, service bandwidth configuration is adjusted according to actual flow situation, until until band width configuration is reasonable.To industry
The reasonable evaluation for band width configuration of being engaged in mainly considers the duration statistic and PRT and CIR/PIR of PCE and PPE according to type of service
Relativeness.
After business monitoring a period of time of a PW (Pseudo Wire, pseudo-wire) carrying, its available real-time traffic
The guarantee bandwidth of its setting and the percentage of peak bandwidth are accounted for respectively, it can be from according to the relationship of real-time traffic PRT and CIR/PIR
To carry out Bandwidth adjustment from the aspect of two:
PRT is compared with CIR/PIR size: when the maximum value of PRT is more than the setting value in each service bandwidth model, need to examine
Worry is adjusted CIR/PIR, guarantees the reasonable setting of CIR/PIR.Such as a base station TD, if the maximum value of its PRT
Less than its CIR, then the CIR setting of PW can be suitably turned down；If the maximum value of its PRT is greater than 0.9PIR, need suitably to be turned up
The PIR value of PW.
In the comparison for observing duration accounting in the period when PCE/PPE different value: guaranteeing information according to the real-time traffic of business
The rate accounting PCE and real-time traffic peak information rate accounting PPE of business in different value in entire observation cycle when
Between length, when its time span deviate service bandwidth model in recommended value when, it is contemplated that CIR/PIR is adjusted.Such as one
A base station TD considers the CIR that PW is turned up if the time of its PCE≤1 is less than the 50% of entire observation time；If PCE≤1
Time is greater than the 60% of entire observation time, then considers the CIR for turning down PW.It is greater than 50% when the time of PCE >=1 and PPE≤0.9
When, then consider that CIR is turned up, it is on the contrary then turn down CIR；And the time for working as PPE >=0.9 is greater than 1%, need to consider the PIR that PW is turned up.
