Fig. 4 be according to an embodiment of the invention for a long time the time slot of sub-module distribute the particular flow sheet of method rationally, as shown in Figure 4, specifically may further comprise the steps:
Step S402, the low order time slot is intersected after order (refer to TU11, TU12 in SDH, the TU3 level is intersected) the ordering arrangement, analyze the destination AU at time slot order place, and send signals to the source AU of this AU, combination is abstracted into some basic time-division time slots streams;
Step S404, in all basic time-division time slots streams, sub-module when selecting AU number maximum trial in source to be arranged into, wherein, if sub-module can be arranged this time-division time slot stream can find the time, then dispose concrete time slot and intersect, otherwise just report the not enough mistake of time-division resource;
Step S406, in remaining time-division time slot stream, calculate source AU and arrange the into coupling number of the time-division time slot stream of time-division, the time-division time slot stream of selecting coupling number maximum (non-zero) is as current time-division time slot stream, attempt to arrange advance sub-module when same, wherein, the calculating of coupling number has embodied professional relevance, and, if all coupling number averages are 0, then forward the time slot stream that step S412 attempts arranging mark to come out to;
Whether step S408, the time slot that detects this time-division block configuration surpass the dispersion threshold of setting, if do not have, then current time-division time slot stream are arranged into sub-module when same;
Step S410, if when being arranged into the time slot of sub-module when same and surpassing preset threshold, then current time-division time slot being failed to be sold at auction is designated as special time-division time slot stream, sub-module in the time of wouldn't being arranged into forwards step S406 then to;
The time-division time slot stream that step S412, trial configuration flag are come out;
Step S414, to attempt the configurations match number be 0 and the unmarked time-division time slot stream that comes out; And
Step S416, circulation execution in step S406 dispose all time-division time slot stream to step S416, up to configuration successful or the not enough mistake of generation time-division resource.
Like this, just finished the process that the time slot of sub-module is for a long time distributed rationally.
As mentioned above, the core of whole invention comprises three parts on the whole: (1) intersects to the low order time slot orders, with substantially the come out unit of time-division time slot stream as subsequent analysis; When (2) arranging time slot to flow to during sub-module, sub-module when preferred at first according to the coupling number; And (3) be configured than multi-service in the sub-module at that time, when surpassing dispersion threshold, and sub-module in the time of being arranged into other.
Summarize foregoing and can see that in the present invention, the implementation step of core comprises:
One, analyzes this all low order time slots intersection orders to be processed, judge whether to have disposed low-order service according to system logic AUG, and be organized into basic time-division time slot stream format, in time-division time slot stream, allow a plurality of AU to be crossed to a destination AU;
Two, in all basic time-division time slots streams, sub-module when selecting AU number maximum trial in source to be arranged into wherein, if sub-module can be arranged this time-division time slot stream can find the time, then disposes concrete time slot and intersects; Otherwise, report the not enough mistake of time-division resource.If the cross-capacity of maximum source AU numbers sub-module when all are single in the system then can directly be concluded, in current time-division time slot stream can't be arranged in the system, need report not enough mistake of time-division in addition;
Three, be configured business in the sub-module at that time, then at configuration subsequent timeslot stream, may originate AU and the time time-division in the sub-module go into AU repetition arranged, promptly professional existence is related, at this moment, sub-module when adopting the coupling number to decide current time slots stream which is arranged into, sub-module when attempting being arranged into that mates the number maximum;
Four, before configuration, whether the time slot that detects this time-division block configuration surpasses the dispersion threshold of setting, if do not have, then current time-division time slot stream is arranged into sub-module when same, wherein, dispersion threshold has reflected the time sub-module capacity more than needed of expectation indirectly, its setting can be appointed as a fixed value, also can adopt the mode of dynamic-configuration, dispose custom, use different dispersion threshold according to different clients;
Five, if when being arranged into the time slot of sub-module when same and surpassing preset threshold, then current time-division time slot being failed to be sold at auction is designated as special time-division time slot stream (SPECIAL state), sub-module in the time of wouldn't being arranged into, and jumping to for the 3rd step then continues to select other time slot stream to carry out;
Six, attempt the time slot stream that configuration flag is the SPECIAL state, mate number this moment is 0;
Seven, attempting the configurations match number is 0 and unmarked time-division time slot stream for SPECIAL; And
Eight, circulation is carried out above-mentionedly three to eight, disposes all time-division time slot stream, up to configuration successful or the not enough mistake of time-division resource takes place.The not enough wrong reason of time-division resource takes place to be comprised: the cross-capacity of sub-module is too little when configuration professional too many and some.
Fig. 5 be adopt the time slot of sub-module for a long time of the present invention distribute rationally after the method time-division time slot stream the time the schematic diagram of crossedpath in the sub matrix.As shown in Figure 5, sub-module and many one way traffics when having disposed 3 4*4, they are configured to destination A1, A3, B1 and B2 respectively, and the dispersion threshold of setting is 75.Adopt method of the present invention, business not only can be distributed to sub-module when a plurality of, success is disposed existing professional, and provide the leeway that the time-division adjusts, such as, the newly-increased A2 of client intersects to the time slot of B2, and sub-module still has the free time during still because of 1#, still can set up cross reference as shown in phantom in FIG., still business can be joined logical.
In sum, the method for the optimization time-division resource that the present invention proposes, the business that can guarantee are distributed to sub-module when a plurality of more uniformly, and can be not concurrent because of producing the too many time-division, and reduce actual crossing.This has significance for the general character of joining of raising equipment when high traffic disposes.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
