Description
Technical field
The present invention relates to the communications field, in particular to a kind of multiple time division configuration method and device.
Background technology
Technical on SDH Network (Synchronous Digital Hierarchy, referred to as SDH) is developed widely and is applied in optical communication field.Along with becoming increasingly abundant and scientific and technological progress of social life, the demand in optical communication field is also more and more diversified, and optical-fiber network can be realized the adjustment of business flexibly fast, can better meet different clients' various demands.This is just proposing more harsh requirement aspect time-slot cross configuration to SDH equipment or network element.
In Technical on SDH Network, if between two network elements or single network element internal there is transfer of data, just must carry out time slot configuration.The function of time slot configuration is exactly for all given output time slot and input time slot, determines concrete crossedpath in transmitting procedure.Normally on webmaster, configure after time-slot cross relation, by network element control processor (Net Control Processor, referred to as NCP) issue time-slot cross order to time slot algorithm module, through the processing of algorithm, obtain concrete various path configurations command result.NCP is issued to each veneer in network element by these configuration order results again, is realized the cross-over configuration of business by veneer, realizes the connection in path between input time slot and output time slot.Wherein, the object of time slot algorithm is exactly: the input time slot issuing according to webmaster and output time slot, arrange the time slot stream communication path in hardware resource (empty sub-module, time sub-module), and complete the calculating of time slot configuration function.
The position of output time slot and input time slot may be between tabula rasa, may be also that tabula rasa is to tributary card.A certain time slot may only need the intersection that just can directly be completed out and enter by space division cross matrix, also may need the intersection of having been come together out and having been entered by space division cross matrix and cross-interaction matrix of time division.The development level of current hardware technology has determined for administrative unit (Administration Unit, referred to as AU) level time slot signal can be by the realization of AU level space division cross matrix, if and utilize space division cross to complete the intersection of this rank lower than the AU that the time slot signal of AU rank can not be followed its place, they just can only rely on empty sub-module and time sub-module cooperation complete intersection.Certainly, for certain technical requirement, also may specify all must complete configuration by space division cross matrix is disposable for AU level time slot signal, for the time slot signal lower than AU rank must through empty sub-module and time sub-module cooperation complete intersection.In order to realize the signal transmission lower than AU rank between signal plate, time-division inside modules realizes the time-slot cross lower than AU rank, time carry out AU level signal time gas exchange by the connection of administrative unit groups (Administration Unit Group, referred to as AUG) bus between AU level space division cross matrix and signal plate between sub-module and signal plate.
Although time sub-module can realize any intersection lower than AU level signal, but due to the impact across time-division factor in the restriction of single time-division module capacity itself and many times sub-modules, still not can solve the problem of low order time interval resource configuration in enormous quantities, so that how to optimize utilizes resource, the problem that can save again in ensureing to be configured to power time, sub-module must be considered in just becoming time slot configuration process.
If there is no the treatment mechanism of the many time-divisions that package, for many times sub-module when the time slot configuration, just likely occur that time-division resource also has part idle, but cannot continue the possibility of configuration, or for same time slot data, there is the different order that issues, sometimes success failed situation sometimes.

Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
Fig. 1 is the multiple time division configuration method flow chart according to the embodiment of the present invention.As shown in Figure 1, comprise according to the multiple time division configuration method of the embodiment of the present invention:
Step S102, divides irrelevant group, wherein, includes one or more input time slot ends and/or the related time slot of output time slot end in each irrelevant group.
Step S104, determines that above-mentioned irrelevant group comprises that output time slot terminal number order maximum irrelevant group is maximum irrelevant group.
Step S106, is configured the irrelevant group of above-mentioned maximum.
In said method, the division of irrelevant group, has reduced as much as possible time slot input time slot end and has been dealt into the possibility that causes the wasting of resources when multiple on sub-module, has ensured the optimization utilization of time-division resource., preferentially the irrelevant group of maximum is configured meanwhile, has applied and first configured greatly, then configure little configuration sequence, improved the probability of configuration successful.
As shown in Figure 2, Fig. 2 has represented the example (example 1) of a multiple time division configuration, sub-module while having two in figure, and twill part represents that the time-division of this part is occupied, the part of white represents that the time-division of this part is idle.Also have two irrelevant group, as shown in Figure 3, if then sub-module 1 of first configuration-independent group 2, so irrelevant group 1 just cannot be configured, and can cause configuration failure simultaneously.But, if use said method, as shown in Figure 4, sub-module 1 when the group 1 that will have nothing to do is configured to, sub-module 2 when irrelevant group 2 is configured to, will find that configuration is successful.
Preferably, in step S102, input time slot end and/or the related time slot of output time slot end include but not limited to: input time slot end and/or output time slot end are crossed to the undetermined time slot of output time slot end of same time slot end.
In specific implementation process, the time slot signal of AU rank does not need to participate in the division of irrelevant group, directly completes cross-over configuration by empty sub-module.
Output time slot time sub-module definite time slot of out position (output time slot end), can preferentially carry out time-division position distribution, do not need to participate in the division of irrelevant group yet.Now, the principle of time-division configuration is while being configured to output time slot place in sub-module, there is directly connecting of definite implantation site (input time slot end) for input time slot end, for do not determine implantation site one of this time-division module assignment idle enter AUG (input time slot end), if can not find the idle AUG that enters, return to failure.
Only have output time slot time sub-module the undetermined time slot of out position, just need to have nothing to do group division.
And the principle that irrelevant group is divided is: by time slot enter and/or the related time slot of output time slot end is divided in same irrelevant group, so-called association refers to that time-slot cross arrives same AUG.
Preferably, step S104, may further include following processing:
(1) select time slot terminal number order maximum irrelevant group as the irrelevant group of maximum.
(2), in the time there is maximum irrelevant group of multiple output time slot terminal number orders, select maximum irrelevant group of input time slot terminal number order wherein as the irrelevant group of maximum.
If the output time slot terminal number order maximum in certain irrelevant group, this irrelevant group is exactly maximum irrelevant group so.If output time slot terminal number order maximum contain several irrelevant groups, so just taking these irrelevant group the inside input time slot terminal number order maximums for the maximum group that has nothing to do.
Preferably, the further following processing of bag of step S106:
(1) while irrelevant maximum group being configured to input time slot end place one or more of the irrelevant group of this maximum, in sub-module, comprise take input time slot end maximum time sub-module on.
(2) if this time the idle input time slot end of sub-module and idle output time slot end cannot meet the configuration requirement of the irrelevant group of this maximum, irrelevant this maximum group is configured to sub-module while removing this outer in sub-module, comprise when remaining take input time slot end maximum time sub-module on, until meet the configuration requirement of the irrelevant group of this maximum.
(3) if there is no meet the time sub-module of the configuration requirement of the irrelevant group of this maximum, split the irrelevant group of this maximum, return to step S104.
Having determined after maximum irrelevant group, while preferentially irrelevant this maximum group being configured to input time slot end place one or more of the irrelevant group of this maximum, in sub-module, comprise take input time slot end maximum time sub-module on, while being configured to these the not busy input time slot end of sub-module hollow minimum time sub-module on, if this module cannot meet the configuration requirement of the irrelevant group of described maximum, irrelevant this maximum group being changed to sub-module while being fitted on another gets on, can preferentially select to get rid of the minimum time sub-module of the not busy input time slot end of sub-module hollow when remaining after this module is configured, this way can be utilized time-division module resource to greatest extent.If there is not the time sub-module of the configuration requirement that meets the irrelevant group of this maximum in the last discovery of fruit, split the irrelevant group of this maximum, return to step S104, redefine the irrelevant group of a maximum, above-mentioned steps is carried out in circulation.
Preferably, after step S106, can further include following processing: judge whether that all irrelevant group all configures completely, if so, finishes configuration, otherwise carries out the step of the irrelevant group of described definite maximum.
So can guarantee that all irrelevant group all can be configured.
In sum, as shown in Figure 5, multiple time division configuration method according to the preferred embodiment of the invention, can comprise the following steps:
Step S502, divides irrelevant group.
Step S504, determines maximum irrelevant group.
Step S506, the maximum irrelevant group of configuration.
Step S508, judges whether success of configuration, if the unsuccessful step S510 that carries out of fruit is successful carry out step S512.
Step S510, splits maximum irrelevant group, returns to step S504.
Step S512, judges whether to also have remaining irrelevant group, is to return to step S504, otherwise finishes.
Below in conjunction with example 2 and Fig. 6 to Figure 10, above preferred embodiment is elaborated.
The prerequisite of example 2: all output time slots time sub-module the time slot determined of position completed configuration, and all space division cross without time-division configuration have also completed configuration.The time slot of all AU ranks has completed time slot configuration.
The environment of example: as shown in Figure 7, time sub-module capacity be all 5 × 5AUG, (the sub-module when 1#) time-division of sub-module 1 wherein time has taken 2 × 2AUG, time sub-module 2 (the sub-module when 2#) time-division taken 3 × 3AUG.The AU being surrounded by circle in Fig. 7 to Figure 10 represents to distribute the AU of use.
The first step, the time slot that will configure this have nothing to do group division.For the convenience of narrating, regard time slot the intersection of the upper business of certain logic AUG to the upper business of certain logic AUG as, be indifferent to the factor of port and plate.Need the time slot lower than AU rank of configuration as follows:
AUG1?TU1→AUG4?TU1，
AUG2?TU1→AUG4?TU2，
AUG2?TU1→AUG5?TU1，
AUG3?TU1→AUG4?TU3，
AUG3?TU1→AUG5?TU2，
AUG6?TU1→AUG8?TU1，
AUG6?TU1→AUG9?TU1，
AUG7?TU1→AUG9?TU2。
Here suppose No. 1 AUG and No. 7 AUG time sub-module 1 there is time-division implantation site (input time slot end), and 2AU and the 1AU of respectively corresponding time-division, entering with out position of remaining other AUG is all unallocated.The time-slot cross of all tributary units (Tributary Unit, referred to as TU) rank is defaulted as TU12's (speed that represents TU, also comprises TU11, TU3 etc.).
According to the division principle of irrelevant group, can be divided into two irrelevant group, the irrelevant group of 1# and the irrelevant group of 2#, as shown in Figure 6:
The 1# group that has nothing to do:
AUG1?TU1→AUG4?TU1，
AUG2?TU1→AUG4?TU2，
AUG2?TU1→AUG5?TU1，
AUG3?TU1→AUG4?TU3，
AUG3?TU1→AUG5?TU2。
The 2# group that has nothing to do:
AUG6?TU1→AUG8?TU1，
AUG6?TU1→AUG9?TU1，
AUG7?TU1→AUG9?TU2。
Second step, determines (calculating) maximum irrelevant group.According to the calculating principle of the irrelevant group of maximum, first compare the number of the AUG at time slot place, both 2, then the number of input time slot place AUG relatively, the irrelevant group of 1# is that the irrelevant group of 3,2# is 2, clearly, the irrelevant group of 1# is maximum irrelevant group.
The 3rd step, starts the irrelevant group of maximum to be configured, first, calculate maximum irrelevant group with time sub-module suitability.First, calculate with time sub-module 1 suitability, when output time slot AUG number 2 is less than, the free time of sub-module 1 goes out AU number 3, removes 1 input time slot AUG having distributed, when remaining input time slot AUG number 2 is less than, the free time of sub-module 1 enters AU number 3, sub-module 1 can be configured to time.Then, calculate with time sub-module 2 suitability, when output time slot AUG number 2 equals, the free time of sub-module 2 goes out AU number 2, when input time slot AUG number 3 is greater than, the free time of sub-module 2 enters AU number 2, sub-module can not be configured to 2# time.
The 4th step, the maximum irrelevant group of configuration.By time sub-module 1 in the position that enters 3AU, 4AU distribute and feed AUG2 and AUG3, the position that goes out 3AU, 4AU is distributed and is provided AUG4 and AUG5, distribute owing to entering AUG1, therefore do not need to distribute again.Configuration for the irrelevant group of maximum completes, as shown in Figure 8.
The 5th step, calculates maximum irrelevant group.Due to one irrelevant group of residue, the 2# group that has nothing to do, so do not need to calculate.
The 6th step, starts the irrelevant group of maximum to be configured, first, calculate maximum irrelevant group with time sub-module suitability.First, calculate with time sub-module 1 suitability, when output time slot AUG number 2 is greater than, the free time of sub-module 1 goes out AU number 1, does not meet adaptive condition.Then, calculate with time sub-module 2 suitability, when output time slot AUG number 2 equals, the free time of sub-module 2 goes out AU number 2, when input time slot AUG number 2 equals, the free time of sub-module 2 enters AU number 2, sub-module 2 can be configured to time.
The maximum irrelevant group of the 7th step configuration.By time sub-module 2 in the position that enters 4AU, 5AU distribute and feed AUG6 and AUG7, the position that goes out 4AU, 5AU is distributed and is provided AUG8 and AUG9, as shown in Figure 9.Configuration for the irrelevant group of maximum completes.
The 8th step is calculated maximum irrelevant group.Because the irrelevant group of residue number is 0, finish.
If do not adopt the method, if the method being configured according to general order as shown in figure 10, first configures the irrelevant group of 2#, the irrelevant group of 1# just cannot configure.Even if irrelevant 1# assembling and dismantling are divided into elementary unit groups, can not complete configuration.
