And for example, what different signals had can transmit separately, what have must have dependence, then try to achieve the available resources of all signals at first respectively, then according to mutual mapping relations between different transmission resource (for example, wavelength of optical signal, signal of telecommunication time slot etc.), obtain transmitting resource mapping table, point out available resources and logical relation thereof.
And for example, the dependence between unlike signal is set by the setting of equipment again sometimes, the processing that must be correlated with according to the setting of equipment when calculating.
Below in conjunction with example shown in Figure 4 above-mentioned preferred account form is described.
Fig. 4 is the internal structure schematic diagram of the complicated transmission node of the example according to the present invention.As shown in Figure 4, in this transmission node, the veneer performance is as follows:
A top side (line side) of light service board and photoelectricity mixed service veneer, transmission be light signal, once business can only be used a kind of wavelength, but selectable wavelength is divided into 1, can transmit the multi-wavelength; 2, transmit a kind of wavelength only.Below a side (client's side), transmission be the signal of telecommunication, wherein once business can only be used a time slot.Being configured among the figure:
A following side (client's side) of electric industry affair veneer and photoelectricity mixed service veneer, transmission be the once professional signal of telecommunication that can only use a time slot of the signal of telecommunication.
Photoelectricity mixing veneer can be linked into the signal of telecommunication of different time-gap in the light signal of a wavelength and transmit.
Close A1, A2, the A3 input port of ripple veneer and can once import any one wavelength in the business, but closing and can inserting optical wavelength on the A4 input port of ripple veneer is λ 1, λ 2, λ 3, the signal of λ 4, but current being set at can only allow tuning specific wavelength input, at this moment, tuning wavelength is λ 3, and promptly current can only be the signal of λ 3 by wavelength.
The photoelectricity mixed service veneer 1 energy transmitting optical signal and the signal of telecommunication just can transmit but the signal of telecommunication need be converted into light signal,
Its light signal that can transmit has only wavelength X 1, and its signal of telecommunication that can transmit is that time slot is the signal of t1.
The signal of telecommunication that electric industry affair veneer 1 can transmit is time slot t1, the signal of t2.
The signal of telecommunication that electric industry affair veneer 2 can transmit is time slot t2, the signal of t3.
The light signal that photoelectricity mixed service veneer 2 can transmit is a wavelength X 1; And can be light signal with t1 and t3 conversion of signals.
The light signal that photoelectricity mixed service veneer 3 can transmit is a wavelength X 3, and λ 4; And can be with t1, t2 and t3 conversion of signals are light signal.
Close the ripple veneer and have the function that the synthetic multiplexing ripple of various wavelength is transmitted, its access interface is divided into 1, can insert a kind of (as can unconditionally receiving λ 1, λ 2, and λ 3, any one among the λ 4) in multi-wavelength's signal arbitrarily; 2, can in multi-wavelength's signal, can only insert under the certain condition wherein a kind of wavelength information number (as being λ 1 when the receivable signal of port, λ 2, λ 3, and λ 4, but when on this moment this port be tuned to when inserting signal and being λ 1, then can not receive λ 2, λ 3, λ 4 signals; When on this moment this port be tuned to when inserting signal and being λ 2, then can not receive λ 1, λ 3, λ 4 signals).In addition, because the identical signal of wavelength can produce mutually and disturb, need (be λ 1 signal on the light service board 1 can not insert simultaneously close on the ripple veneer 1) inequality with λ 1 signal on the photoelectricity mixed service veneer 1 so be input to the wavelength of the different business that closes the ripple veneer.
Electric industry can the be engaged in arbitrary signal of veneer of electricity switching board is transferred on the different photoelectricity mixed service veneers.So the signal of telecommunication of electric industry affair veneer 1 and electric industry affair veneer 2 can be selected any one of photoelectricity mixed service veneer 2 and photoelectricity mixed service veneer 3 by electric power board, the signal of telecommunication is converted into light signal transmits.In addition, the signal of identical time slot can produce on electric switching board and disturb, so the same time, the time slot of the signal of telecommunication on the electric switching board can not be identical (being that t3 signal on the photoelectricity mixed service veneer 2 and the t3 signal on the photoelectricity mixed service veneer 3 can not insert on the electric switching board 1 simultaneously).
Account form according to the topological structure of above-mentioned veneer performance and transmission node inside is as follows:
(1) when any professional foundation do not arranged, be wavelength X 1 from client's side to the maximum spendable transmission resource that transmits interface B, λ 2, and λ 3, the signal of λ 4 and, time slot is t1, t2, the signal of t3.But limit owing to close the performance of ripple veneer 1, the A4 port can not use λ 4 wavelength, thus λ 4 current be unavailable resource.Current spendable transmission resource is a wavelength X 1, and λ 2, the signal of λ 3 and, time slot is t1, t2, the signal of t3 is wherein.Light signal does not have dependence, and the signal of telecommunication depends on light signal: time slot is the signal that the availability of the signal of t1 depends on wavelength X 1, is λ 1 so time slot is the signal of telecommunication and the wavelength of t1, and λ 3 forms two groups and transmits the resources mapping; Time slot is that the signal of t2 can be that λ 3 forms one group of available transport resources mapping with wavelength; Time slot is that the signal (electric industry affair veneer 2) of t3 can be that λ 1 (photoelectricity mixed service veneer 2) and λ 3 (photoelectricity mixed service veneer 3) form totally two groups of available transport resources mappings with wavelength.Five groups of available transport resources mappings altogether.
(2) after light service board 1 usefulness λ 2 foundation business, photoelectricity mixed service veneer 1 promptly becomes unavailable veneer, and λ 2 wavelength are unavailable resource.This moment maximum spendable transmission resource be wavelength X 1, λ 3, the signal of λ 4 and, time slot is t1, the signal of t2 and t3.And current available transmission resource is a wavelength is λ 1, λ 3 and, time slot is t1, the signal of t2 and t3, wherein time slot is that the signal of t1 can be the light signal (photoelectricity mixed service veneer 1 and photoelectricity mixed service veneer 2) of λ 1 and the light signal (photoelectricity mixed service veneer 3) that wavelength is λ 3 with wavelength, forms two groups of available transport resources mappings; Time slot on the electric industry affair veneer 1 is that the signal of t2 can be one group of available transport resources mapping of light signal (photoelectricity mixed service veneer 3) composition of λ 3 with wavelength; Time slot on the electric industry affair veneer 2 is that the signal of t3 can insert the light signal that wavelength is λ 1 (photoelectricity mixed service veneer 2) and wavelength is the light signal (photoelectricity mixed service veneer 3) of λ 3, forms two groups of available transport resources mappings altogether.Five available transport resources mappings altogether.
(3) use the signal of telecommunication of time slot when electricity consumption service board 1,, use the light signal output of wavelength X 3 through photoelectricity mixed service veneer 3 as t1.Then this moment the maximum spendable transmission resource light signal (photoelectricity mixed service veneer 1 and photoelectricity mixed service veneer 2) that is λ 1 and, time slot is t1, the signal of t2 and t3.Wherein, the time slot of photoelectricity mixed service veneer 1 is that the signal of t1 can be linked on the signal that wavelength on it is λ 1 and transmits, because though electric industry affair veneer 1 uses the signal of telecommunication of t1, but be to be linked on the light signal that wavelength is λ 3, these two wavelength of optical signal differences, belong to different carrier waves, so can allow two different signals to use the signal of telecommunication of time slot simultaneously as t1.At this moment, time slot is that the signal of telecommunication and the wavelength of t1 are that λ 1 forms the mapping of one group of transmission resource; Time slot on the electric industry affair veneer 2 is that the signal of telecommunication of t2 can be the light signal of λ 1 with the wavelength on the photoelectricity mixing veneer 2, and the λ 3 on the photoelectricity mixing veneer 3, forms two groups of available transport resources mappings altogether.Time slot on the electric industry affair veneer 2 is that the wavelength that the signal of telecommunication of t3 can insert on the photoelectricity mixing veneer 2 is that the light signal of λ 3 and the wavelength on the photoelectricity mixing veneer 2 are the light signal of λ 1, forms two groups of available transport resources mappings altogether.Four available transport resources mappings altogether.
When the resource model processing module receives the inner connection state information that connects the renewal that acquisition module sends, connect the signal transmission path that obtains the place according to this inside, all veneers on the traverse path successively, according to the account form of various resource information correspondences, get the intersection of the various available transport resources of all veneers.Thereby obtain the resource state information of transmission node on this transmission path.
The resource model processing module is a path logic starting point with the signal input veneer of intranodal transfer path, signal output veneer with transfer path is transmission path set in the logic terminal point structure transmission node of path, and in the satellite information of every transmission paths, indicate the type of transmission path, signal type on the transmission path, and total resource collection that transmits.
The resource model processing module is inquired about employed resource of current business and reserved resource to service resource management, and from the total resources state model it is deleted, and obtains above-mentioned available transmission node resource status model.
Preferably, after carrying out above-mentioned steps S106, can also comprise following processing:
(1) the resource model processing module is divided the resource performance of the resource state information of transmission node that available transmission node resource status model managed according to attribute of performance;
Wherein, above-mentioned resource performance refers to the attribute of performance of veneer, for example, and the power of output light, light non-linear, the time slot of dispersion situation, signal, the fade performance of signal, error rate thresholding etc.
(2) the resource model processing module adopt with divide after the corresponding regulation scheme adjusting resource performance of resource performance.
Describe above-mentioned preferred implementation process in detail below in conjunction with embodiment.In preferred implementation process, said process may further include following processing:
Step 1: when the operating state of each veneer in system start-up or the transmission node and performance information change, begin to carry out the processing of intranodal performance information.
Step 2: divide for example fault warning, signal impairment etc. according to attribute of performance.
This shows, detection in the time of can realizing that the intranodal Management Unit is in available and unavailable change, when the characteristic parameter of Management Unit changes, also can trigger the automatic detection procedure of resource model state, thereby realize the state of real-time update intra-node resource model.Except resource information, can also detect the performance information and the warning information of Management Unit, thereby can obtain the work state information with processing components.
Step 3: in different resource performance kind processing lists, choose corresponding processing scheme according to resource performance.Wherein fault warning comprises unglazedly, and power is less than thresholding, and the error rate is higher than thresholding etc.; The signal impairment class comprises optical dispersion, polarization, PDM time delay etc.
Step 4: checking feature is revised the value of cycle counter, if surpass the regulation cycle-index then forward step 6 to.
The value of cycle counter is set, and is for fear of the operation endless loop.
Step 5: the performance number with default serves as to carry out processing scheme, and the veneer configuration parameter is made amendment.
By above-mentioned processing, can realize that Management Unit is in alarm or the automatic adjustment of key parameter and obtaining automatically of automatic adjusting method when not satisfying normal operating condition.
Step 6: re-execute the processing of step 1, obtain the amended new resource performance of veneer configuration parameter, and run to step 2 always.
Step 7: the modification result of handling failure alarm.If the normal use of veneer can't be handled and influence to fault, then in available transmission node resource status model, this signal transmission path is labeled as fault.And show concrete failure cause.If have fault but do not influence the normal use of veneer, then in this resource status model, this signal transmission path is labeled as unusually, and shows concrete abnormal cause.If fault warning is revised the back in normal range of operation, then show this bars transmission path, and be labeled as normal.
By above-mentioned processing, the resource model processing module can be finished the resource status in the automatic detection transmission node, obtain the resource status model, and according to the performance and the alarm of each veneer in the system, regulate automatically, the final realization satisfied the required performance requirement of the correct transmission signals of system, and the resource model of available transmission is reported.
Preferably, after the resource model processing module was regulated resource performance, can also comprise following processing: the resource state information of transmission node that the resource model processing module is managed available transmission node resource status model was general grand to link.
By above-mentioned processing, not only can realize the resource status model of single node, and can realize the detection and the renewal of the resource state information of transmission node in the multinode network.
The preferred process mode of above-mentioned resource state information of transmission node is described below in conjunction with Fig. 5.
Fig. 5 is the flow chart of the processing method of resource state information of transmission node according to the preferred embodiment of the invention.As shown in Figure 5, this process mainly comprises following processing:
