As shown in Figure 1, be the schematic flow sheet of first embodiment of the present invention electricity relaying collocation method, present embodiment may further comprise the steps:
When the OSNR value of each website that travels through professional route, can select the head end website of professional route or terminal website as the initial website of traversal, travel through successively along professional route direction, after having traveled through the professional route of traffic direction, continue the reciprocal professional route of traffic direction is traveled through.
For the OSNR value of each multiplex section of making the professional route after the configuration is relatively more balanced, therefore the computational methods of OSNR equilibrium valve also are provided, as shown in Figure 2, the schematic flow sheet for the OSNR equilibrium valve of the first embodiment of the present invention is calculated may further comprise the steps:
The calculating of the multiplexing hop count in the step 201 can be drawn by following formula:
If A is the OSNR value of multiplex section reality after the emulation, C is the OSNR tolerance value of receiving terminal OTU, and the hypothesis multiplex section is that (N is a positive integer to the N section, default value is 1, is 6 to the maximum), determine the number of multiplexing hop count then according to SO, when SO＜A, determine multiplexing hop count N, wherein
SO=C-10 * log
10N＜A, N constantly increases (maximum of N is 6) since 1;
After determining multiplexing hop count N, the formula of step 202 calculating OSNR equilibrium valve is as follows:
Determine the OSNR equilibrium valve according to SFO, as SFO〉during A, determine that the OSNR equilibrium valve is FO, wherein
SFO=FO-10 * l og
10N, FO begins constantly to increase to SO (can at every turn increase definite value or underrange) from T.
Because the OSNR equilibrium valve is usually above the OSNR tolerance value of OTU, when disposing with the OSNR equilibrium valve as the standard that judges whether to dispose, can make the OSNR value equilibrium more of each multiplex section of whole service route, thus the raising signal transmission quality.
As shown in Figure 3, schematic flow sheet for second embodiment of the present invention electricity relaying collocation method, compare with a last embodiment, present embodiment is before the OSNR value of each website of the professional route of traversal, also increased step 100, judged promptly whether the head end website of professional route and the OSNR value of terminal website meet the OSNR tolerance value of the OTU of professional receiving terminal, if meet the OSNR tolerance value of the OTU of professional receiving terminal, then do not need to carry out electric relaying configuration, otherwise execution in step 101 travels through.Present embodiment also is applicable to the computational methods of the OSNR equilibrium valve of an embodiment.
As shown in Figure 4, be the schematic flow sheet of the 3rd embodiment of the present invention electricity relaying collocation method, present embodiment may further comprise the steps:
Whether the OSNR value of step 100, the head end website of judging professional route and terminal website meets the OSNR tolerance limit of the OTU of professional receiving terminal, if meet the OSNR tolerance limit of the OTU of professional receiving terminal, does not then need to carry out electric relaying configuration, otherwise execution in step 101;
If step 104c does not meet, then put and search for new non-light before the website and put website from the non-light that disposes electric relaying, and this non-light to the traffic direction of putting website on and carry out electric relaying configuration on the opposite direction of traffic direction, the electric relaying of the original configuration of deletion goes back to step 104a more then;
In the present embodiment to the site configuration of traffic direction intact after, also to the opposite direction of traffic direction be configured, can guarantee that like this OSNR value of head end website and terminal website all meets the OSNR tolerance limit of the OTU of first and last website.Present embodiment also is applicable to the computational methods of the OSNR equilibrium valve of an embodiment.
