With reference to Fig. 3, be further used as preferred embodiment, it comprises:
B1, link scanning control module are that effective E1 of access divides the channel resource being used in detection;
B2, link scanning control module exchange link block to numeral and send the order of setting up switching matrix, thus arrange two tuples of source time slot and object time slot;
B3, link scanning control module send the order and parameter that detect to link detecting acquisition module, and start detection timer;
B4, link detecting acquisition module according to the order received and optimum configurations relevant parameter, and are added up E1 link data bag;
After B5, detection timer arrive the time of setting, link scanning control module exchanges link block to numeral and sends dismounting order, delete two tuples of respective sources time slot and object time slot, and send the order and parameter that stop automatically detecting to link detecting acquisition module;
B6, link detecting acquisition module return the statistics of E1 link data bag, and judge that whether the type of E1 link is correct by link scanning control module according to the data of statistics.
Wherein, effective E1 is the Interface status of access E1 link is effective.The present invention is only that effective E1 distributes channel resource, and invalid E1 does not distribute channel resource, effectively can reduce the waste of resource.Meanwhile, the present invention, when processing a fairly large number of E1, can adopt the mode of batch process automatically to detect, to alleviate the load of link and to improve the efficiency of link detecting and collection.
Be further used as preferred embodiment, described step B1, it is specially:
Judge whether link detecting acquisition module adopts symmetric pattern to carry out link and automatically detect, if so, then link scanning control module adopts symmetric pattern to be that the effective E1 accessed divides the channel resource being used in detection; Otherwise then link scanning control module adopts asymmetric mode to be that the effective E1 accessed divides the channel resource being used in detection.
Wherein, light mouth or electric mouth for accessing E1s in E1 link access module adopt paired mode to manage, and the E1s of access so just can form E1 couple.In the balanced mode, link detecting acquisition module only needs to detect the link carried in a right E1 of every a pair E1, and the link in another one E1 is then determined by the link carried in this E1, thus the efficiency of link detecting is doubled.
Be further used as preferred embodiment, judge the type of E1 link this step whether correct by link scanning control module according to the data of statistics in described step B6, it is specially:
The percentage accounting for total data bag according to correct data bag in the data of statistics by link scanning control module judges that whether the type of E1 link is correct, if the percentage that correct data bag accounts for total data bag is more than or equal to the percentage preset, then represent that the type of E1 link is correct, now, the type of mode to E1 link of Flash memory is adopted to store and continue automatically to detect the E1 link of next type; Otherwise, then represent that the type of E1 link is incorrect, now, continues automatically to detect the E1 link of next type.
Wherein, the percentage P preset is that P must be more than or equal to the 99% percentage P namely preset between 99% ~ 100% in advance according to the constant of actual conditions setting.And Flash memory to refer to memory be erasable: in the time period T0 preset, the type memory retention of E1 link; After having crossed the time period T0 preset, the type memory of E1 link can be wiped free of, thus effectively reduces the drain sweep probability of link of the same type.
Here for HDLC agreement, the type of its E1 link data bag has four kinds: correct packet msu, short bag fisu, crc error bag crcErr, termination bag abortErr.Wherein msu, fisu are correct packet, and crcErr, abortErr are the packet of mistake.If the percentage that correct packet accounts for total data bag (packet of correct packet+mistake) is not less than the percentage P preset, so the type of link is correct.For reducing the probability of link error detection, needing to adopt the method for statistics to carry out statistical data packet, the link data bag quantity in statistics a period of time T, and then judging that whether the type of link is correct.
Here two parameter P and T are related to, the arranging of this two parameters directly can have influence on the accuracy and efficiency that link detects automatically, if P value is excessive, link meeting drain sweep, if T value is excessive, the time of every bar link detecting lengthens, and the number of links that unit interval class detects is few, and the efficiency of link detecting can reduce.In practice, general P is arranged to 99%, T and establishes and be worth into 1 second.
With reference to Fig. 4, be further used as preferred embodiment, described step C, it comprises:
C1, link scanning control module are the channel resource of E1 link assignment for gathering after detecting;
C2, link scanning control module exchange link block to numeral and send the order of setting up switching matrix;
C3, link scanning control module send acquisition to link detecting acquisition module;
C4, link detecting acquisition module arrange acquisition parameter according to the acquisition received, and gather in units of time slot to corresponding E1 link data.
With reference to Fig. 5, be further used as preferred embodiment, described step C1, it comprises:
C11, link scanning control module carry out classification statistics to the E1 link after detection, thus obtain the quantity of E1 link of the same type;
C12, judge whether the quantity of current E1 link of the same type is less than total number of link detecting acquisition module, if, then perform step C13, otherwise, then the quantity of E1 link of the same type is adjusted, make the quantity of the E1 link of the same type after adjustment be less than total number of link detecting acquisition module and perform step C13;
C13, structure load balancing tree, carry out equilibrium statistics to the speed of E1 link;
C14, link scanning control module are the channel resource of E1 link assignment for gathering after speed equilibrium statistics.
The process of automatic detection and collection all needs to take physical resource on link detecting acquisition module, and the resource that testing process takies and the resource that gatherer process takies all can be reused.The balancing link load form of expression mainly link acquisition, because the final form of expression link acquisition of link scanning.Load balancing can have two kinds of criterions: the quantity that link is total and the total speed of link.Weigh the load of each link detecting acquisition module with the quantity that link is total, this standard comparing is simple, only need link detecting acquisition module one by one to distribute and gather resource, but its accuracy is not high.And the load of each link detecting acquisition module is weighed with the speed that link is total, this standard considers that duty ratio is comparatively comprehensive, but algorithm is very complicated.
Present invention employs the load-balancing algorithm simultaneously comprising number of links equilibrium and speed equilibrium and carry out load balancing to data acquisition link road, two of load balancing criterions organically combined, accuracy is high and algorithm is relatively simple.Be provided with N number of link detecting acquisition module, detailed process of carrying out load balancing of the present invention is as follows:
First, link scanning control module carries out classification statistics to the E1 link after detection, thus the quantity obtaining E1 link of the same type is Ln (35>n>0);
Then, compare the size of Ln and N, if Ln>N, then the quantity of E1 link of the same type is adjusted, make Ln<N, otherwise, then construct load balancing tree;
Then, structure load balancing tree, carries out equilibrium statistics to the speed of link;
Finally, link scanning control module is the channel resource of link assignment for gathering after speed equilibrium.
Wherein, if Ln>N, then the quantity of E1 link of the same type is adjusted, make the detailed process of Ln<N as follows: a, be respectively each link detecting acquisition module and distribute an E1 link, after being assigned, the quantity Ln of E1 link of the same type reduces N number of; B, judge whether current Ln meets Ln<N, if also do not meet, then repeat step a, until Ln<N.In fact, if Ln>N, then the number of links of this type of each link detecting acquisition module distributing is (Ln-Ln%N)/N, and here " % " refers to and get remainder operation.
Suppose also have M(M>N now) bar link is not assigned with, and the process of structure load balancing tree is as follows: (1) chooses 2 minimum values in current link rate value; (2) the value addition chosen these 2 obtains a new rate value, and replaces 2 original minimum values with the new rate value obtained, and participates in sequence (link numerical value number now becomes M-2+1); (3) in this M-2+1 link rate value, choose 2 minimum values again, repeat (2), until number of links is less than or equal to N.
First method of the present invention distributes collection resource with number of links standard, and then carries out equilibrium to the speed of link, effectively can reduce the number of plies of structure load balancing tree, improve the speed of algorithm.
With reference to Fig. 4, be further used as preferred embodiment, after described step C14, be also provided with step C15, described step C15 is specially it:
After the channel resource for gathering is assigned, link scanning control module gathers link to every bar and monitors, and judges whether this link has data within the time preset, if there are data, then continues to perform step C2; Otherwise, then the channel resource that this link occupies is discharged.
Wherein, the time T1 preset sets according to actual needs, generally gets T1 and is less than 1s(as got T1=0.5s).
Step C15 comprise to collection link monitor, can reclaim be not used further to collection channel resource, minimizing resource waste.
Meanwhile, the link detecting of different E1 and link data collection walk abreast and carry out, and link detecting and link data collection all need Resources allocation.If the resource that link detecting takies is too much and the resource of link acquisition can not get distributing always, the deadlock of resource will be formed.In order to prevent the deadlock of resource, need utilance problem link detecting Resourse Distribute being optimized to efficiency and the resource that just can solve link detecting.Specific practice is as follows: each is taken turns link detecting and distributes resource as much as possible, to improve the efficiency of link detecting; And the inspection that link detecting will discharge after completing
Survey resource and be used for link data collection, until the link data collection of epicycle complete after release link data gather resource carry out next round link detecting, namely next round link detecting Resources allocation is just carried out after last round of resource all releases (link detecting and link data gather resource and all release).This ensures that there the link detected and necessarily have resource for gathering, improve the efficiency that link data gathers, and take full advantage of resource.
