Fig. 2 illustrates the schematic flow sheet of network performance evaluation optimization method in an embodiment, as in figure 2 it is shown, the method in this embodiment includes:
Step S21: obtain the bandwidth availability ratio of each ring inner link of current looped network；
Step S22: the bandwidth availability ratio according to each ring inner link, it is determined that bandwidth availability ratio average in the ring of looped network before deserving；
Step S23: according to the bandwidth availability ratio of bandwidth availability ratio average, each ring inner link in the ring of described current looped network, it is determined that balancing link load degree in ring；
Step S24: the bandwidth availability ratio according to each ring inner link, is defined as in ring by the maximum of the bandwidth availability ratio of link in each ring the most high bandwidth utilization of link；
Step S25: according to the most high bandwidth utilization of link in balancing link load degree, described ring in described ring, it is determined that the network performance of current looped network。
It will be understood by those skilled in the art that, in above-mentioned steps S22 to step S23 fixed ring really, in the process of balancing link load degree and step S24 fixed ring really, the process of the most high bandwidth utilization of link can be order in no particular order, the network performance of current looped network carries out, as long as can be determined in step s 25 based on the two parameter simultaneously。
Scheme according to the embodiment of the present invention as above, due in practical application substantially based on domain dilatation, network condition is estimated for ultimate unit by the present embodiment scheme with ring, closer to practical application, from the angle of the network optimization, by flow equalization in ring, it is possible to avoid the blindness domain dilatation caused due to single hop heavy duty, the degree of depth realizing network bandwidth resources is taped the latent power, and promotes network resource utilization。
Wherein, when above-mentioned steps S25 determines the network performance of current looped network, in a concrete example, it is possible to adopt following manner to carry out:
By balancing link load degree in described ring with default equilibrium degree threshold ratio relatively, it is determined that link equalization rank in the ring corresponding with balancing link load degree in described ring；

According to the pair relationhip of link equalization rank, described most high bandwidth utilization rank in described ring, it is determined that the network performance of described current looped network。
It is to be noted, it will be appreciated by those skilled in the art that, the bandwidth availability ratio of above-mentioned ring inner link, it is actually the assembly average of a relatively long time interior (such as one day, one week or even one month), therefore, extended " in ring the balancing link load degree " determined and " in ring link most high bandwidth utilization " by " bandwidth availability ratio of ring inner link ", be also the assembly average of (such as a day, a week or even month) in a relatively long time。
Thus what was certain was that, above-mentioned according to ring in the most high bandwidth utilization of link determines the network performance of current looped network in balancing link load degree, ring time, and when determining the network performance of current looped network according to the pair relationhip of link equalization rank in ring, most high bandwidth utilization rank, substantially in conjunction with the meansigma methods of long period, network performance is estimated, thus erased each shorter time carve the details of (such as every 15 minutes or even short time period per minute)。Therefore, in order to more fully network performance is estimated, it is necessary to the details in each moment is reflected to a certain extent。Accordingly, in a concrete example, when determining the network performance of current looped network in step s 25, it is also possible to combine to when in the ring of current looped network, link carries out traffic sampling, gathered flow exceedes the number of times of threshold value and comprehensively determines。This number of times may be for whole current looped network, it is also possible to is for each ring inner link in current looped network。
To determine busy degree for the ring inner link in current looped network, Fig. 3 illustrates the schematic flow sheet of network performance evaluation optimization method in this example, as it is shown on figure 3, the method in this example is for the method in above-mentioned Fig. 2, before above-mentioned steps S25, further comprise the steps of:
Step S2401: obtain total sampling number that each ring inner link in described current looped network is carried out in preset time period traffic sampling, and when each ring inner link is carried out traffic sampling, the flow that gathers exceed the super early warning value sampling number of Flow Limit definite value of this ring inner link；
Step S2402: determine the busy degree of each ring inner link according to the super early warning value sampling number of each ring inner link, total sampling number, and the busy degree according to each ring inner link determines link busy degree。In a concrete example, it is possible to be that the maximum in the busy degree of each ring inner link is defined as link busy degree。It will be understood by those skilled in the art that at the busy degree determining each ring inner link, it is also possible to adopt other modes comprehensively to determine link busy degree。
Now, in above-mentioned steps S25, it it is the network performance determining current looped network according to the most high bandwidth utilization of link in balancing link load degree, described ring in described ring, described link busy degree。
Accordingly, in a concrete example, when determining the network performance of current looped network, it is possible to adopt following manner to carry out:
By balancing link load degree in described ring with default equilibrium degree threshold ratio relatively, it is determined that link equalization rank in the ring corresponding with balancing link load degree in described ring；
By most for link in described ring high bandwidth utilization with pre-set bandwidths utilization rate threshold ratio relatively, it is determined that corresponding with the most high bandwidth utilization of link in described ring most high bandwidth utilization rank；
Described link busy degree and default link busy degree threshold value are compared, it is determined that the link busy degree rank corresponding with described link busy degree；
Then according to the pair relationhip of link equalization rank, described most high bandwidth utilization rank, link busy degree rank in described ring, it is determined that the network performance of described current looped network。
To determine busy degree for current looped network, having illustrated the schematic flow sheet of network performance evaluation optimization method in this example in Fig. 4, as shown in Figure 4, the method in this example is for the method in above-mentioned Fig. 2, before above-mentioned steps S25, further comprise the steps of:
Step S2411: obtain total sampling number that each ring inner link in described current looped network is carried out in preset time period traffic sampling, and when each ring inner link is carried out traffic sampling, the flow that gathers exceed the super early warning value sampling number of Flow Limit definite value of this ring inner link；
Step S2412: determine the busy degree of current looped network according to the super early warning value sampling number of each ring inner link, total sampling number。
Now, in above-mentioned steps S25, it is that the busy degree according to the most high bandwidth utilization of link in balancing link load degree, described ring in described ring, described current looped network determines the network performance of current looped network。
Accordingly, in a concrete example, when determining the network performance of current looped network, it is possible to adopt following manner to carry out:
By balancing link load degree in described ring with default equilibrium degree threshold ratio relatively, it is determined that link equalization rank in the ring corresponding with balancing link load degree in described ring；
By most for link in described ring high bandwidth utilization with pre-set bandwidths utilization rate threshold ratio relatively, it is determined that corresponding with the most high bandwidth utilization of link in described ring most high bandwidth utilization rank；
The busy degree of current looped network and the busy degree threshold value of looped network are compared, it is determined that the looped network busy degree rank corresponding with the busy degree of current looped network；
According to the pair relationhip of link equalization rank, described most high bandwidth utilization rank, the busy degree rank of looped network in described ring, it is determined that the network performance of described current looped network。
It will be understood by those skilled in the art that in the explanation of above-mentioned each example, in preset time period, each link can be carried out several times sampling, this is the above-mentioned total sampling number mentioned。And for wherein specifically certain is once sampled, the flow gathered necessarily is confined to the flow in this sampling time section, therefore, in essence, the actual meaning containing " flow velocity " of flow that sampling obtains。
After the network performance determining current looped network based on the mode in above-mentioned each example, namely can according to the network performance of the current looped network determined, determine the network optimization mode to described current looped network corresponding with this network performance, and this network optimization mode can be adopted to be optimized, to improve network performance。
Having illustrated the schematic diagram of loop network link in a concrete example in Fig. 5, shown in Fig. 5, for any one looped network, it includes two kinds of links, a kind of ring inner link within this looped network, a kind of ring upper level link for the first line of a couplet。
Additionally, for each current looped network, it there may be and accesses the lower floor's ring deserving front looped network, shown in Fig. 5, for the looped network of backbone layer, it is connected to the ring of multiple convergence-level under its meeting, and the ring of convergence-level can be connected to down the ring of multiple Access Layer。Therefore, when the second line of a couplet looped network connect under current looped network exists, further each second line of a couplet looped network of current looped network can also be analyzed, further network performance is estimated, particularly in the network performance of current looped network not good when, can further determine that out specifically which second line of a couplet looped network goes wrong。
Accordingly, as shown in Figure 2, Figure 3, Figure 4, the method in the present embodiment can also include:
Step S26: obtain each second line of a couplet looped network under described current looped network, and respectively using each second line of a couplet looped network as current looped network, be then back to above-mentioned steps S21, reacquire the bandwidth availability ratio of each ring inner link of current looped network, carry out above-mentioned analysis process。Namely, after obtaining each second line of a couplet looped network, above-mentioned analysis process can be repeated for each second line of a couplet looped network, such that it is able to accordingly each second line of a couplet looped network is estimated, it is simple to determine specifically which second line of a couplet looped network goes wrong。
In addition, ring upper level link for current looped network, aforesaid way can also be adopted to determine the network performance of each ring upper level link, namely for each ring upper level link of current looped network, adopt the above-mentioned processing mode that link in ring is same, determine ring upper level link equilibrium degree, the most high bandwidth utilization of ring upper level link, the busy degree rank of ring upper level link, on the one hand can according to ring upper level link equilibrium degree, after the most high bandwidth utilization of ring upper level link determines the network performance of ring upper level link, further the busy degree rank of coupling collar upper level link comprehensively determines the network performance of ring upper level link in case of need, can also be directly according to ring upper level link equilibrium degree on the other hand, the most high bandwidth utilization of ring upper level link, the busy degree rank of ring upper level link comprehensively determines the network performance of ring upper level link。
Generally only have two ring upper level link due to current each current looped network, thus can simplify on the basis of the above。Accordingly, in another specific example, as shown in Figure 2, Figure 3, Figure 4, the method in the present embodiment can also include:
Step S201: obtain the bandwidth availability ratio of each ring upper level link of current looped network；
Step S202: when the difference of bandwidth availability ratio of each ring upper level link of current looped network is more than preset difference value threshold value, the flow of ring upper level link high for bandwidth availability ratio is imported the ring upper level link that bandwidth availability ratio is low。
Thus, two ring upper level link are generally only had due to current looped network, such that it is able to directly utilize the difference of the bandwidth availability ratio of these two ring upper level link, determine their performance, and when the difference of the broadband utilization rate of the two is higher than preset difference value threshold value, the flow of ring upper level link high for bandwidth availability ratio is imported the ring upper level link that bandwidth availability ratio is low, to realize the optimization of the performance of two ring upper level link。
After the flow of the ring upper level link that bandwidth availability ratio is high imports the ring upper level link that bandwidth availability ratio is low, may result in the change of the flow etc. of each ring inner link of current looped network, therefore, after the flow of above-mentioned steps S202 that bandwidth availability ratio is high ring upper level link imports the ring upper level link that bandwidth availability ratio is low, above-mentioned steps S21 can be entered, again the performance of the ring inner link of current looped network is estimated and optimizes。
Based on the method for the embodiment of the present invention as above, the process below in conjunction with the network performance evaluation optimization in a concrete example is illustrated。For simplicity of illustration, it is illustrate only for evaluating and optimizing of current looped network in the following description, is referred to the mode in this embodiment carries out for each ring upper level link of current looped network, the network performance evaluation of second line of a couplet looped network and optimization。
Scheme for the embodiment of the present invention, when the network performance of current looped network is estimated, first the bandwidth availability ratio of each ring inner link of current looped network is obtained, bandwidth availability ratio be characterize the network bandwidth occupied how much with parameter of network congestion, embodiment of the present invention scheme can the direct extracting data of monitor in real time from network monitoring system, can also being network directly carries out test obtain above-mentioned bandwidth availability ratio, this not be limited by the embodiment of the present invention。It will be understood by those skilled in the art that bandwidth availability ratio described herein is actually the assembly average of a relatively long time interior (such as one day, one week or even one month)。
Subsequently, the bandwidth availability ratio according to each ring inner link, it is determined that bandwidth availability ratio average in the ring of looped network before deserving。
In a concrete example, it is assumed that current looped network has k bar ring inner link, and the bandwidth availability ratio of i-th ring inner link is xi, then in ring, bandwidth availability ratio average can be expressed as:
Wherein,Represent bandwidth availability ratio average in ring。
Above-mentioned example is the average of bandwidth availability ratio directly to ask for each ring inner link is illustrated as bandwidth availability ratio average in ring, in other applied environment, can also using the weighted mean of the bandwidth availability ratio of each ring inner link as bandwidth availability ratio average in ring, such as, available following formula is determined:
Wherein,Represent bandwidth availability ratio average in ring, xiRepresent the bandwidth availability ratio of i-th ring inner link, aiRepresent the bandwidth availability ratio x of i-th ring inner linkiWeight coefficient, a1+a2+...+ak=1。Wherein, weight coefficient aiCan determine in conjunction with various factors such as the position of this ring inner link, importances。
Subsequently, can according to bandwidth availability ratio average in the ring of current looped networkThe bandwidth availability ratio x of each ring inner linki, it is determined that balancing link load degree in ring。In a concrete example, in this ring, balancing link load degree can adopt following formula to determine:
Wherein, E represents balancing link load degree in ring, xiRepresent the bandwidth availability ratio of i-th ring inner link,Represent bandwidth availability ratio meansigma methods。
Have 4 for ring inner link, then in above-mentioned ring, balancing link load degree can be expressed as:
On the other hand, bandwidth availability ratio based on each ring inner link of above-mentioned acquisition, it may also be determined that the most high bandwidth utilization of link in ring, can being defined as in ring by the maximum of the bandwidth availability ratio of link in each ring the most high bandwidth utilization of link, namely in ring, the most high bandwidth utilization of link can be expressed as:
xm=max (xi)
Wherein, xmRepresenting in ring the most high bandwidth utilization of link, max () is the function asking for maximum。
On the other hand, can also obtain total sampling number that each ring inner link in described current looped network is carried out in preset time period traffic sampling, and when each ring inner link is carried out traffic sampling, the flow that gathers exceed the super early warning value sampling number of Flow Limit definite value of this ring inner link。And then the busy degree of each ring inner link or the busy degree of current looped network can be determined therefrom that, in case of need, it is also possible to be the busy degree of busy degree and the current looped network simultaneously determining ring inner link。The super early warning value sampling number of above-mentioned each ring inner link, total sampling number, can the direct extracting data of monitor in real time from network monitoring system, can also being in certain period of time, network directly carries out test to obtain these data, this not be limited by the embodiment of the present invention。
Determine each ring inner link busy spend time, it is N that i-th ring inner link is carried out total sampling number of traffic sampling by noteiall, when this i-th ring inner link is carried out traffic sampling, the super early warning value sampling number of the flow that the gathers Flow Limit definite value that exceedes this ring inner link be Nil, then the busy degree M of i-th ring inner linkilCan be expressed as:
After the busy degree determining each ring inner link, can comprehensively determine a link busy degree according to the busy degree of each ring inner link, in order to carry out follow-up analysis。In a concrete example, it is possible to be that the maximum in the busy degree of each ring inner link is defined as link busy degree。Have k bar ring inner link for current looped network equally, then link busy degree can be expressed as:
Determine current looped network busy spend time, it is N that i-th ring inner link is carried out total sampling number of traffic sampling by noteiall, when this i-th ring inner link is carried out traffic sampling, the super early warning value sampling number of the flow that the gathers Flow Limit definite value that exceedes this ring inner link be Nil, then the busy degree M of current looped networkhCan be expressed as:Certainly, it will be understood by those skilled in the art that the busy degree that other modes can also be adopted to determine current looped network, for instance in conjunction with the busy degree busy degree comprehensively determining current looped network etc. of each ring inner link。
Wherein it is determined that link busy degree Ml, or determine current looped network busy degree MhProcess, it is possible to be the most high bandwidth utilization x of link in balancing link load degree E, ring in coupling collarmAfter determining the network performance of current looped network, determine again in case there is a need, in order to carry out comprehensive consideration。The most high bandwidth utilization x of link in balancing link load degree E, ring can also be determined in ring with above-mentionedmProcess carry out simultaneously。Illustrate respectively below for both modes。
In first kind of way, i.e. the most high bandwidth utilization x of link in balancing link load degree E, ring in coupling collarmDetermine the network performance of current looped network, determine current looped network busy degree M in case there is a need againhOr link busy degree MlFor example, concrete process can be discussed further below。
First, according to the most high bandwidth utilization x of link in balancing link load degree E, ring in the above-mentioned ring determinedm, it is determined that the network performance of current looped network。In a concrete example, it is possible to adopt following manner to carry out:
By balancing link load degree E in ring and default equilibrium degree threshold value ETRelatively, it is determined that link equalization rank in the ring corresponding with balancing link load degree in ring；
By most for link in ring high bandwidth utilization xmWith pre-set bandwidths utilization rate threshold value xTRelatively, it is determined that corresponding with the most high bandwidth utilization of link in described ring most high bandwidth utilization rank；
Then according to the pair relationhip of link equalization rank, most high bandwidth utilization rank in ring, it is determined that the network performance of described current looped network。
In a concrete example, in ring, link equalization rank only has two-stage, it is assumed that in ring, balancing link load degree E is more than or equal to default equilibrium degree threshold value ET, then it is believed that in the ring of correspondence link equalization rank be high, or other marks (such as 1) of corresponding level, otherwise it is assumed that link equalization rank is low in the ring of correspondence, or other marks (such as 0) of corresponding level。
Similar, also only have two-stage for most high bandwidth utilization rank, it is assumed that the most high bandwidth utilization x of link in ringmMore than or equal to pre-set bandwidths utilization rate threshold value xT, then it is believed that the most high bandwidth utilization rank of correspondence is high, or other marks (such as 1) of corresponding level, otherwise it is assumed that the most high bandwidth utilization rank of correspondence is low, or other marks (such as 0) of corresponding level。
With rank by the high and low example that is expressed as, table 1 below illustrates the pair relationhip according to link equalization rank in ring, most high bandwidth utilization rank in a concrete example, it is determined that the schematic diagram of the pair relationhip of the network performance of current looped network。
Table 1
In conjunction with upper table 1 it is known that when link equalization rank high bandwidth utilization rank high, most is also high in ring, illustrate that looped network load is significantly high, have a strong impact on looped network network performance, so that carry out early warning, and warning level should be higher, for instance upper advanced warning grade 3 shown in table 1。Shown in upper table 1, it is also possible to provide the network optimization mode of correspondence, for instance looped network network is carried out dilatation or cutover etc. simultaneously。
And link equalization rank high bandwidth utilization rank low, most is high in ring, illustrating that the single hop load of looped network is significantly high, looped network network is unhealthy, so that carry out early warning, and warning level is of a relatively high, for instance upper advanced warning grade 2 shown in table 1。Shown in upper table 1, it is also possible to provide the network optimization mode of correspondence, for instance looped network network is carried out dilatation or cutover etc. simultaneously。
And link equalization rank high bandwidth utilization rank high, most is low in ring, current in good condition of looped network is described, thus can without early warning。But although load can not be got rid of and do not arrive early warning value, but the impact that duration of peak value head causes, thus the network optimization mode provided can be to be analyzed further, for instance in conjunction with busy degree, looped network network is analyzed etc.。
In ring, low, the most high bandwidth utilization level of link equalization rank is also low, looped network underloading is described, but load imbalance, the better performances of at least single link is described, but although load can not be got rid of and do not arrive early warning value, but the impact that duration of peak value head causes, thus provide the early warning that warning level is low, for instance upper advanced warning grade 1 shown in table 1。Shown in upper table 1, it is also possible to provide the network optimization mode of correspondence, for instance need to be analyzed further, for instance in conjunction with busy degree, looped network network is analyzed etc. simultaneously。
When being analyzed in conjunction with busy degree, for current looped network, it is possible to by busy for current looped network degree MhDegree threshold value M busy in default looped networkhTCompare, it is determined that the busy degree rank of looped network that degree busy in current looped network is corresponding。
In a concrete example, only has two-stage for the busy degree rank of the looped network of current looped network, it is assumed that current looped network busy degree MhMore than or equal to the busy degree threshold value M of default looped networkhT, then it is believed that the busy degree rank of looped network of current looped network is high, or other marks (such as 1) of corresponding level, otherwise it is assumed that the looped network busy degree rank of current looped network is low, or other marks (such as 0) of corresponding level。
If being 1 or without early warning in conjunction with the advanced warning grade of the network performance determined in above-mentioned table 1, and determine that the busy degree rank of looped network of current looped network is for height, although then may determine that the not heavy duty of current looped network, and duration of peak value head, thus the network optimization mode that can provide correspondence is dilatation or cutover。If being 1 or without early warning in conjunction with the advanced warning grade of the network performance determined in above-mentioned table 1, and determine that the looped network busy degree rank of current looped network is low, then may determine that the network of current looped network is very healthy, it is not necessary to make any adjustments。
On the other hand, it is possible to be when needs are analyzed in conjunction with busy degree, directly in conjunction with link busy degree MlThe looped network performance of current looped network is comprehensively analyzed, it is also possible to be in conjunction with current looped network busy degree MhDetermine when the looped network busy degree rank of current looped network is high, then for link busy degree MlOr the busy degree M of each ring inner linkilComprehensively analyzing, the busy degree to determine specifically which bar ring inner link is higher。
With to link busy degree MlIt is analyzed as example, concrete for link busy degree MlIt is analyzed, when determining link busy degree rank, it is possible to similar otherwise with the above-mentioned looped network to current looped network busy degree level, for instance to only have two-stage for link busy degree rank, it is assumed that link busy degree MlMore than or equal to default link busy degree threshold value MlT, then it is believed that link busy degree rank is high, or other marks (such as 1) of corresponding level, otherwise it is assumed that link busy degree rank is low, or other marks (such as 0) of corresponding level。
With the busy degree M to each ring inner linkilIt is analyzed as example, the concrete busy degree M for ring inner linkilIt is analyzed, when determining the busy degree rank of ring inner link, it is possible to similar otherwise with the above-mentioned looped network to current looped network busy degree level, it is assumed for example that the busy degree M of i-th ring inner linkilMore than or equal to the busy degree threshold value M of default looped networkilT, then it is believed that the busy degree rank of i-th ring inner link is high, or other marks (such as 1) of corresponding level, otherwise it is assumed that the busy degree rank of i-th ring inner link is low, or other marks (such as 0) of corresponding level。
